Title: 2.5td Chip
Post by: largecol on 23 February 2009, 17:50:39
Heloo guys, i`m giving very serious thought to chipping the old tractor now that i`ve put all the electrical faults to bed (at last)!!! I`ve seen lots of threads and advice on this issue on the forum - just wondering if anyones had any experience with this company http://www.chiptuning.at  They`re making all kinds of easy-fit extra power with low cost and low risk claims. Seams far too : good to be true - or is it?? To be honest i`ve never heard of a plug`n`play chip system before - but if it saves pulling out the ECU and not having to search the attic for me soldering iron i`m all for it!!  :D :D

drop a PM to 'omegatoy' i think he still has access to TD chips

I run a chip in my 2.5TD, as its rubbish without.

It makes the car much better, more drivable imho.

If you have an auto, your gearbox won't take it though, so its a non starter if you don't have a manual (unless you want to fit a stronger autobox)

Yeah i`ve seen the scary tales of boxes going all hari-kari!! Am i right in thinking its an ar35 i need? Can this be donored from any 3L mig, or are their specifics?? Still after info on these plug-in units - can it really be THAT simple?? :o

ar35, yup.  You need to reuse the torque convertor and bellhousing from your ar25 though.

The chips themselves are plug in, no real problem if you have an ecu with socketed chips.

Got bored with your link, crap site, lost interest in 5s, sorry

lol most of them are easy to fit as they just increase the fuel pressure,
which puts the injector pumps under severe strain and usually 'dangle berries's it within 10k!!! thsts why they are so easy to fit! and even worse to fit them you have to remove the ECU to identify the wires to connect them to!!!!!

Having just chipped one myself here are the good points using the mentioned chip above.

Before - Fuel economy 25-30mpg around town, 45mpg on a long steady run

After - Fuel economy - 35-40mpg around town, 60mpg+ on a long steady run. Infact i managed just under 65mpg on a 200mile trip from cold over the weekend, but i was driving like a grandad.

Power is greatly increased especially low down. As far as i know the AR35 will simply plug and play, i think they have the same internals as the AR25 just better quality materials. If you go for the manual option then budget for a 3.0v6clutch.

The hardest part is finding someone who will fit it. The boards are pretty old fashioned and tough, but you still need a decent der-soldering station. I got a local computer repair to do it for 30 quid but it took a lot of ringing around before i could find somewhere.

Good luck

Is that via MID or via manual calculation

I have to admit thats via the computer. I used 18 litres of fuel over 189miles.

is that computer that says 18l used?  I'd be interested in how much you've actually used :y

been thinking about chipping my elite 2.5 td 1995 will it make much difference? only worry is that it's manual low geared rear wheel drive which makes it rubbish in snow and ice could'nt use it at all a couple of weeks ago would'nt even get it off the drive!

Post by: largecol on 23 February 2009, 20:09:28
Mmm, so as long as i can source a box with a decent mechanic attached i`m sorted!!!lol There`s a couple of decent vx breakers around these parts so the hunt is on - any pointers as to cost of a box guys?? Also it may sound like a daft question but how`d you tell if a donor box is sound, other than driving the thing before its removed???  :-?

the gboxes [ar35] come up on here regularly, wouldnt like to quote prices though but some scrapyards are a bit "keen" on charging the earth, i would say anything between £70-£100 is a fair price but believe me itll be money well spent!, but dont forget a change of pants when the chip is fitted ;D you wont believe the difference :y

worth it, and not bad in snow (if you drive sensibly)

Chip it fellas - you'll wonder why you've not done it sooner!

Fuel consumption on mine is a (proven) constant 33mpg - no matter how or where it's driven (not tried it with the caravan in tow yet).
Several other members also get similar consumption figures.

I get that unchipped & an auto AR25 calculated (not MID because I'm in the cheap seats)!
Would like to improve on it though

I think mine has now settled at about 40mpg real average with upto 45-50 showing on the MID. On a good run I can do a real 50mpg with about 60mpg on the MID!

So I have established that the MID is as good as useless! The chip, however, is very much worthwhile.  :)

Ok, Ok, i`m convinced!! You guys have talked me into it!!  ;D So I`m now making the first deposit into the Miggy-bank!!Sounds like i`ll need to budget for some new driving shoes - as opposed to slippers if things go as planned!! Made a couple of enquiries re: boxes at the breakers and the cheeky monkeys wanted £200+!!! Well i spose patience is a virtue? :D :D Watch this space!!!

I would say your best bet would be to whip your ECU out and open it up frst to see if it needs to be socketed to accept the chip (take note of the serial number).

On the picture below, it is the chip on the left (with the white plastic cover on) - the pic shows a socketed board (good news) if your chip is direct into the board you will need to solder a socket in before you can install the chip.

Then PM TheBoy or Omegatoy to arrange the chip, and keep your eyes peeled in the for sale section for an AR35, or ask MutantCav as he always seems to have a few lurking about!

I have just re-brimmed tractor to manually calculate economy.  97 miles, 13.5l, that included some 3 figure speeds (obviously on a private road).  Thats from a auto.

With all the foregoing Jamie, that's not bad.
My maths come up with just under 33mpg for yours - same consumption as mine. As yours is an auto and shown little mercy - I'd be happy.

Not good enough in my book, but improvement on the 28/29 I get from it non-chipped, even being miss daisy

Doubt any computer shops will do it - christ, most of the current crop can only just plug in cards!

Try tv repair places...

ill have to go ask them do you buy the socket with the chip or do you have to buy that as an extra im realy no good with electronics
Title: Re: 2.5td Chip

You will need to buy the socket.  Have you checked if yours already has a socket?

Desolder old chip.

Solder in socket (available from Maplin/Farnell/Whoever)

Plug old chip in and make sure it all still works.

Remove old chip, plug in new one.

I just got the chip in mine, I had a field techie (who knows how to solder properly) perform the change of chip which was a nightmare the old chip refused to be unsoldered for some reason, with all necessary tools and a very experienced person doing the job...

The car now runs very well, it certainly pushes me into the back of the seat when I accelerate, which it does very happily...  Definate Grin factor...  I just need to watch the loud pedal now... lol...

Oh, anyone know how to switch off the speed limiter???

It is now chipped and as an update, it did seem not to kick in, so must be a characteristic of my original chip...

I do seem to find the car very jumpy at around 15-20 mph now though, which I need to work on, unless it is a poor low speed mapping on the chip...
