Title: facelft 2.5td tuning
Post by: conalnugent on 29 December 2012, 03:28:04
i know its already been asked a million times about tuning this motor.  To date its 79k miles, converted 5 speed manual and LSD.  Going to blank off erg at next service which ive plugs to bang in and while im at it have pre painted manifold.  Any hows shes my daily barge and needs a bit more get up and go.  Would love to have the time and money to get a 530d engine in her but as i said its a daily driver and down time needs to be less than a days graft.  Any ways been looking at these chips from poland that are on ebay and hearing good things about them but still want a little more power.  So what else can be done? even down to the small things.  I hear removing the back box with a straight through will help and a decent air filter.  Also can someone recommend a tuning box.  Are they any good? I know there pricey yes but just need something thats quick and easy to sort out as its the dad mobile lol.

Cheers

If its manual, its good to go chipping wise. The 2.5TD was actually de-tuned in the Omega, just chipping it back to full BMW spec makes a big difference.

TheBoy or Omegatoy are people to talk to on chipping these beasts  :y

Facelift ... with EGR ... so should be an X25DT lump ;)

Couldn't see any reference to facelift. All tractors have egr.

Was it an auto, converted to a manual, or was it always manual?

That was how I read it. Wonder if ECU was changed during conversion (GM fit a different ECU, depending on manual or auto!).

Ideally need ECU type, guess its 428 - same as my old tractor. I loved the chip in that...  ...but not the cost of rear tyres ::)

The first 2 AR25s didn't ::)

The AR35 was OK.  Although I still maintain that the GM autobox isn't suited to that engine.

to answer all it was an auto converted manual with the wiring crossed off to trick it into thinking its still auto, lol still brings a smile to my face when it brings up on the info display auto transmission  :y :y  Its a 2001 facelift 2.5td the bmw engine.  I think only the very very 1st of the face lifts got these, was the shape i wanted with the donkey i was after.  Not to sure what brain is in it though but for the auto to manual conversion its the orginonal auto brain. 

Is there a chip that can bring it up to about 170bhp? or would a map or tuning box be the order of the day?

Not to my knowledge. MID can only be programmed to each car spec/engine/transmission, nothing unique text wise can be done.

dam.

Anyways back on topic, and suggestions for a tuning box that'll up it to 170bhp or there abouts?  Any for sale on here?

I'm no TD expert, but on these you want to chip them, rather than tuning box.

As TheBoy was asking earlier, he wanted to know what ECU you have as it changed between manual/auto. (and year)

Someone will advise of a suitable chip, some are plug and play, some require soldering.

not sure will check it before this evening is out a report back.  Ive an inkling it'll be the one that requires desoldering etc but could be lucky

427 is socket I believe, going on little research  :)

most ecu after 98 were soldered! so you need to put a socket in the board,then chip either to full fat or +10 or less smoke +5 and not far off its your choice on these,
small jobs worth doing,
backbox removal its rather heavy for what it does and gas escapes better withlittle or no
extra noise worth mentionning ;D
blank egr as you say some say it worth removing the plastic iintake and throttle body and replacing with a straight piece of pipe,
can also fit manual switch to intercooler, as stupid vauxhall only have it come on with main fans,very rare,it makes a difference as intake temps can come down by as much as 30degree,s!! :y
carefully very carefully,a quarter of a turn a time,on the wastegate arm, till you are happy when you have chipped it, this will lessen smoke, and give a fair bit more poke until the wastegate catches up with itself, but its worthwhile doing,change gear at around 4k and it dont very often catch up :y
oil change every 3 k with good quality oil makes a difference, as does running on super diesel,
mine would easily light up the tyres in third, so had to back it off a bit for the mrs, :-X

It'll be a 428 ECU then, and it will be soldered.

Some of the ebay ones are really bad.  I had a 428 off a local chap, who many OOF tractor owners use, as they are "known good".  I think, from memory, it was around the BMW spec, so 150+ bhp, with very nice delivery.

  I got one of the chips from omegatoys mate which i still havnt got around to fitting yet. he told me it would put the car back to BMW standard which was 178 bhp and stop most of the soke with that alone. Once I am back in work, i will be on the hunt for an AR35 and then getting the chip fitted. The chip carriers are easily available. I got mine from "Rapid Electronics" and they were only pennies to buy. Will cost more on postage than the cost of one.
