I am looking to get the TD chipped now that I have sorted all the other problems out. So after sorting my fuel pump out, I was feeling confident and the ECU came out for inspection. The only thing is I'm a bit worried about pulling it to pieces so thought I would post some pictures first and ask for some advice.
How do I get the top board off?
I'm guessing the main chipset(s) are in the middle of the 2x PCB's? Please have a look at the pictures and feel free to advise me to what I should do next to identify if I need to socket the board or not... the pics aren't great, but might give you an idea.
Any help muchly appreciated.
Thanks, Platty

Release the white plastic standoff clips, 'unfold' the 2 pcbs (like a book), then take another piccy.
-
Do I have to unplug the ECU to do this? Will this cause any problems if I do?

yes.
It wont cause problems.

Well, I have finally opened up the ECU boards... and I think that it is socketed. I have shown some pictures below - you can make out the socket and the chip being seperate (i think). If anyone could confirm this it would be appreciated! :y

Does anyone know? :(
-
I cant remember which one it is......I know we got it wrong first time and because they are both memory devices, nothing was damaged.

I'm not sure which one either yet... just checking if its socketed or not first. It looks like it to me - but not sure :-/
-
yep swappable mate!! if the ecu is opened like a book its the lowest one on the right hand side!!! i think :'( damn i cant remember and ive questioned meself now!!! but as siad all that will happen is the car will light up the eml and refuse to run or run very poorly

Thanks, great news! So, looking at the picture below, I need to be replacing the one on the left hand side??
(http://img.photobucket.com/albums/v241/chrispy_platt/Mega%20Drive/DSC02134a.jpg)
If this is the case, next question - where do I get one!! Money is waiting to be spent! :y
TIA Happy Platty :D

pm me your email addy with nuber on ecu(ten digit and will email me mate, he will burn you one and you can rejoice in the real power of the diesel!! as well as the far better economy!!

Hi Lads, just saw this post and am very interested to see how this works out and the costs of this little upgrade as i own a 2.5td (beemer eng)

looking at your signature you have big probs cos o the auto bit!!!!

If you chip the diesel but retain the AR25 auto-box, you may trash the box within a few hundred miles. It is not designed to take the higher loads imposed by the chipped engine ...
If you wish to chip you need the AR35 auto-box
HTH

-
As mentioned already, It is a risky job fitting the chip with the AR25, I am only fitting one as I have a manual. I'll let you know what difference it makes though. ;)

I'd like to know how you get on with this as well. Mines a manual so no problems there.

Hiya Platty, you got the chip installed yet? Would be interested to find out how it's running. Mine is manual too and it's something I'll be looking to do if the results are worthwhile.
Are there any jobs I should be looking at getting done in preparation?
Thanks

Hiya, I shall be receiving the chip tomorrow all being well. The guy supplying me is really helpful - and knows his stuff too.
I will fill you in once I have been for a spin tomorrow night (fingers crossed).
Assuming you keep your TD well serviced (oil change evry 3k blah blah etc.) then I dont think there is anything else to do... well I haven't done anything else anyhow. :-/

yep service every 3 k wothout fail, other than that enjoy it!!!!!
there are a few other tricks to get a few more Ggs out of the pot but wont elaborate for a while cos it will seem like a new car once you chip it!!

I am impressed with the 427 chip, to the extent I tried fitting to my 428 ECU. Didn't work - wouldn't rev above 2k :(

Might have a look for a 427, though there is another 428 map to try :-X

Well guys... the chip has arrived and been installed.
All I can say is..........WOW !!! :D
What a difference it has made, and I have only done about 10 miles (all of which flat out) but the difference is significant. It makes the TD drive alot more like a modern diesel engined car as opposed to a Massey Ferguson.
Big difference I noticed was that when changing gears there is no delay before the power comes back on, it just pulls much harder straightaway. If I boot it i'll get a slight puff of black smoke then it clears and were away!
The chap who supplied me (thanks mate :y)has estimated that the power is probably up aroud 150 bhp ish and the torque to about 330 nm. That'll do me just fine!
Highly recommended :D :D :D :D :D :D :D :D :D :D :D :D :D
PS. Thanks for everyones help getting this job done! esp. TheBoy & Omegatoy :y

welcome buddy i
nice isnt it? tis always nice to help a fellow td owner, when you have finished hoofing it around you will find your fuel consumption is better thsn it used to be as wel, so you have gained all round!!!

I'm doing a run down south this weekend, about 200 mile round trip. I do it quite regular and get around 35 mpg... I'll have to see what its like now and report back.
Still gonna be hooning it around for a couple of days though. ;D
-
Makes it a drivable car, rather than the slug it is. That particular map you have is very impressive, particularly in a manual. Shame I cannot run that map in my 428 ECU :'(

I WANT ONE!!!!!!!!!!!! (don't tell the missus tho) ;D
-
I WANT ONE!!!!!!!!!!!! (don't tell the missus tho) ;D
Get one and tell the missus too, cos for what they cost you will get your money back after about 5 tankfuls of juice. The economy is so much better.
I was crusing the motorway today at 80 and the MID was reading 60 mpg (take it with a pinch of salt) - it used to read about 35 at that speed. :)

it will use less fuel when cruising mate, cos the engine isnt working as hard as it used to :y!!!

yup, economy jumped on mine. no idea how accurate mid is, as I never fill it - too lazy, use pay at pump, and can never get enough fuel in to fill....

border line if you have a 427 or 428 ecu (last 3 digits of Bosch part number). 428 needs a bit of soldering.
Also, if you have an auto, forget it....

Nope, mine is Manual. Where do I find the ECU's to find out which one I've got?

Where do I find the ECU's to find out which one I've got?
Open up the bonnet, and on the right hand side (as you look into the engine bay), behind the battery is a triangular shaped plastic fuse box. Open this up and the ECU is on its side in there (silver), pull it upwards and it slides out so that you can see the serial number (X XXX XXX XXX)
If you want to check if it is socketed or not, then you will have to unplug it, bend back the metal tabs and open it up full (T8 & T20 Torx reqd.)
Hope that helps :y

Sweet, I had knee surgery yesterday so it's gonna be a few days at least before I'm out and under the bonnet again but I'll have a look as soon as I can and see where it goes from there. If you don't mind me asking, what ballpark figure are we talking about for getting the car chipped?
Thanks

find out which ecu it is first, if its 428, then you'll need to solder in a socket....
-
This might be a stupid question, but are the TD ECUs interchangeable?
ie - if you have a 428, can you simply change it for one that does have a socket?

simple anser is no.
more complex answer - possibly. You'd have to swap immobiliser and transponders as well. never tried, but may have a go myself.

Ones with IR remotes, very easy. But then, they are all socketed chips anyway ;)
Later RF ones have a much more complex setup with the immobiliser.

Looks like I need to find an AR35 gearbox then!
My ECU doesn't seem to have 427/428 on it though.
I've got :
0 281 001 215
90 379 298
Does that mean anything to anyone?

Imagine the simplest most crude waste gate setup you have ever seen and then simplify it!
On the diseasel, the waste gate is normally closed and only opens as the boost pressure increases. The actual actuator is fed off the turbo boost pressure so as the inlet pressure rises, the waste gate opens therefore reducing the turbos rpm and maintaining a constant boost.
So, if you bugger about with the waste gate actuator then you can up the boost........dont overdo it though or you risk over revving the turbo!
Heres where it gets a little more difficult though, around 1997ish, a MAF was added to the setup to reduce smoke on full chat (to meet the regulations that were coming in) and this monitors the airflow. If it gets a bit high, it backs the fueling off to stop unburnt fuel exiting out the back James Bond style in a cloud of black smoke (because the smoke you see is unburnt fuel!)
This 'improvement' makes it harder to tune the old slug as your always fighting a few lines in code that are backing the fueling off!

We only adjusted the boost by a fraction - just under 0.1bar iirc. Sadly, this wasn't on mine, which has a MAF

I cant comment on how but, I suspect it involves little more than bending the actuator arm......unless you are silly enough to disconnect the actuator all together so the turbo waste gate always stays shut (would need to blank off the air feed to the actuator)!

Only, they didn't do a very good job of it ;D - "My name is Boy, The Boy"
Actually, I keep forgetting to plug the MAF in on mine. Tends to stay that way for weeks. First thing I notice is a stored fault code if I plug Tech2 in...

Very, but don't be too greedy, as its easy to do a lot of damage. You're better off with a chip.
Actually, just noticed you have a slush box. I wouldn't do anything :'(

Does the actuator od have a threaded adjustment?
You might find actually that winding the boost up wont do a lot without the extra fueling of the chip anyway!

Not surprising when you think that its only coming into play at the top end of the rev/boost range......plus as we all know, BMW dont light the fault light when things go wrong!

I didn't know there was any other home for the rev counter other than right at the top ::).
The one thing that does tend to bring it on is the 64 (?) which is a failing injection pump. I guess BMW feel they need to warn drivers that the repair bill is going to hurt ;D

Hmmm, I do miss changing gears, but being quite lazy the auto is the way forward, especially now that I'm getting so old (33 this month!)
I'm guessing it's much tricker to change auto for manual, than just auto to auto?

OH YES !!! and without a Maf There are certain other areas tht can be played with without the Maf pulling it back down!!! :y
You been buggering with the crude waste gate setup?
Would we do such a thing ::)
I am surprised it didn't throw an over boost fault code from the inlet pressure sensor
We only adjusted the boost by a fraction - just under 0.1bar iirc. Sadly, this wasn't on mine, which has a MAF
lolol on that day yes but cn tell you it can go a lot more quite happily with no
adverse effects so far!!!! :y
You bloody hooligan ;D
You measured the boost now then?
yup it now reads 2.60bar ::) and the wife hates it!!!! cos one minute its gently pulling away through the gears as soon as the revs hit 2000 rpm someone is pulling your head into the headrest :y then it just squashes you into the seat :y then the wastegate catches up around 4300 rpm
and thats when you change gear!! :y however the downside is out here there are many cambered hairpin turns which you cant pull away from without spinning the wheels no matter how hard you try >:( so a lot of spain >:( thinks im a hooligan!! mind you a lot of them always get in the way too!!!!

2.6 :o

2.60 bar bloody hell G!!!!! thats nearly 35psi are you mad ???? :o :o
-
yup it now reads 2.60bar ::)
Out of interest, what is the standard boost level?
-
nowere near that platty !! G's car must be pushing 250ish bhp !!! :o :o
-
yup it now reads 2.60bar ::)
Out of interest, what is the standard boost level?
Around 2bar

ohh didnt think they was that high jaime :-[ :-[
-
yeh its a fair bit i must admit but bear in mind i dont have to use the car every day, and the 2.60 is peak boost before the wastegate cuts it, it sure did make the turbo hose expand tho!!! so this is now covered in large zipties to limit the amount it can expand solid pipes would be better but thats impossible although i might try silcon if i can find a company that will do them anyone know any good ones???

Where do I find the ECU's to find out which one I've got?
Open up the bonnet, and on the right hand side (as you look into the engine bay), behind the battery is a triangular shaped plastic fuse box. Open this up and the ECU is on its side in there (silver), pull it upwards and it slides out so that you can see the serial number (X XXX XXX XXX)
If you want to check if it is socketed or not, then you will have to unplug it, bend back the metal tabs and open it up full (T8 & T20 Torx reqd.)
Hope that helps :y
Meanwhile, back at the plot . . . . . . . . . . . .
I have got the ECU out of the car and the first thing I noticed was the number ending in 427 on the back, being the optimist I am I presume this is the number peeps have been talking about....?
(http://i283.photobucket.com/albums/kk288/cheshley/19052008488.jpg)
I have then bent the metal tabs back (and sliced my hand open in the process) and having removed all the Torx heads I have removed the boards and carefully opened them up as described. The first thing I notice is that the 2 centre chips in the run of 4 across the top of the board are different from the pic Platty posted earlier but from reading posts an I right in thinking that it's the chip on the left of the 2 below these that I am interested in . . . . . . ?
(http://i283.photobucket.com/albums/kk288/cheshley/19052008494-1.jpg)
Also, previous posts mention a 10 digit code on this chip. If this chip is the right one, the code printed on it takes the format XX XXX XX XXXX XXXXX.X If this is the wrong chip then it won't matter, but if it is this one, how come I've got a much longer code?
It's all good fun aint it ;)

No, its one of the EPROM devices just behind, 28
pin DIL's (Dual In Line) with the stickers on.
Sadly, they need un-soldering and a socket fitting

Bugger. It's about right that if there's two ways of doing something, mine will be the more complicated!!!!! >:( Soldering ECU boards isn't something that I'll be attempting, any volunteers/recommendations?????????? :-?
I suppose it would make sense to have the new chip available so it can all be put back together at the same time, any chance of someone putting me in touch with Platty's chip provider? (any idea if the provider will be able to do the socket soldering?) :-/

If you cna get the ECU to me, I can fit a socket for you.

The 10 digit number referred to is the ECU number - shown in your first pic as 0 281 001 427. Mine was a 427 too, but had the sockets in already.
I would take Mark up on his offer and get a socket put in. I will pm you with the details of the chip provider so you can speak with him about getting hold of one :y
As said already the chip to be replaced is the left hand side one of the 2 x longer chips in between the 2 x "SIEMENS" chips. You can see the above ECU number on the chip label.

Had my ECU out at the weekend and mine is the same as the one above, soldered. Would be interested in this doing this to mine as well, not far from you either.

It seems some 427s are socketed, some aren't. Not see a 428 socketed yet either. Non MAF ones (2xx) are socketed.
-
Looks like I need to find an AR35 gearbox then!
My ECU doesn't seem to have 427/428 on it though.
I've got :
0 281 001 215
90 379 298
Does that mean anything to anyone?
Older U25DT engine (no MAF), 215 ECU.
So by going with those numbers it looks like mine will work just fine as well (0 281 001 214 on mine). Considering I have just done a long run from Devon to Portsmouth at about 37mpg if I can improve that I will be so much happier when I go back in October.

Your are getting about the same I used to before the chip.
I did 180 miles at the weekend and the average was 49.9 mpg - mixture of m'way, A-roads and traffic so I was pleased! :D
-
Where do I get a chip for a 215 then, in readyness for an AR35!

I GOT ONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Firstly I have to give HUGE thanks to Platty for putting me in touch with his chip provider and to Marks DTM Calib for fitting my ECU out with the required sockets and turning the job around so quickly. I can't thank you guys enough.
Socketed ECU arrived at 12.45 today and by 1pm it was back in the car with the new chip fitted. I can't believe the difference it has made and after wandering around the local roads for a while to make sure all is OK, I've kicked it along the M18 laughing my head off all the way.
I have to get this 'boy racer' complex out of my system before the weekend cos I'm off to Southampton via London so I want to see what the mpg works out at and if I can't keep my foot off the floor it won't be very much!!!!
;D :y ;D :y ;D :y ;D :y ;D :y ;D :y

It would have been there yesterday but, I couldn't get to the post office on Monday!

with a sludgepump gearbox you have to keep it pressed cos its a parasite for power!! ;D ;D

I have had mine in for 2 months and I have calmed down a small amount but have still destroyed a set of rear tyres in 4000 miles :(
The worst thing is that you can get the thing sideways on roundabouts in the dry and that is a serious handful!!!
Cheshley - Really pleased you got it sorted, now you can start enjoying the TD how it was meant to be! :y

Great fun tho ;D

I can't wait for this, who would like to help me fit an AR35 in the Essex area?

Just a couple of things I have noticed while pottering around yesterday:
1. It's very smokey out of the exhaust when you stick your foot on it
and
2. When driving carefully (remember how this is done....?) there is a point in the power delivery between maintaining speed and just backing off a small amount so the car slows a little (hard to describe) when as the power backs off it's quite juddery until the car slows to match the power being input and speed is maintained again.
Neither of these affect the performance and I was glad I went on a rally driving course a few years ago because the roads were wet yesterday and I lost count of the number of times the back end stepped out ;D

WRT smoke - what fuel are you using? I find the more tanks of Asda etc fuel that goes in mine, the more smoky it gradually becomes. I then whack in a couple of tanks of Shell/BP etc, and its fine again for a while.
Also worth renewing fuel filter, and sticking a can of Diesel Magic neat into new fuel filter and running (it will run like a tractor for first few seconds) - ignore the Diesel Magic instructions about shoving in tank ;)
-
WRT smoke??? :-?
I usually fill up at Sainsbury's but I'm going to stick some of the Shell V-Power or BP Ultimate in it when I fill up tomorrow and see if that does anything to help the situation, I'll also pick up a fuel filter and a can of system cleaner.
-
it will smoke when first chipped then it will gradually ease off and only smoke on high revs or crap fuel, the juddery thing is the same as mine its done it since ive had the car its only on a manual you get it think its where the throttle position is just open sending a trickle of fuel in enough to upset the tickover amount which it would be if the throttle was fully closed,
that make sense to you?? :y
-
Certainly does.
I had my garage put a fuel filter in today, only took 10 minutes and then took 2 mechanics 45 minutes to get the car going again. Fixed it by opening the bleed screw on the filter housing, sticking the airline in the fuel filler pipe, packing it with rags and forcing fuel through to the front end. Glad I didn't try to do it at home.......... ::)
-
if thatsn the case i would suggest checking the pump in the tank as they bleed themselves within 30secs after a filter change normally!!!
if not thsat you have a drain back problem or air in it!!!! :y

I'm back, did anyone miss me......? :-?
Just had a few days down inthe Isle of Wight, and bery nice it was too. Not been before but I'll definately be going back, hopefully in the not too distant future 8-)
Anyway, enough of the holiday reviews, still basking in the glory of the increased power since the chip went in but where is this fuel economy everyone was talking about? Drove from here down to my Brother's in Hertfordshire, A1(M), M18, straight down the M1, turn left on the M25. 164 miles and 159 of them on motorway at a steady 80ish and get 37mpg. Not a lot different from what I was getting before :-?
-
Thats odd, I jumped from mid 30s to low 40s in my auto the second the chip went it. Must higher on motorway runs....

not a lot but better? dont forget your probably still in the "ooh i can accelerate faster now style of driving" and if the economy is still the same as was when your driving it harder then thats not bad at all, however when you get used to it i.e. on the same runs you used to do for instance the daiy grind back and forward to work you will notice its not using as much fuel as you used to, take it the car is well serviced air filter and things changed etc?
