i have read loads of stuff on chips to improve performance and mpg of the 2.5 td,but would like to find out where to start?who can offer the best value for money?what works what dosen't?who would fit it or is it really a diy job?would it improve the low speed pick up?would like any advice,and comments off anyone who has chipped there 2.5 td.mine ha done 138.000 engine in :y good nick run very clean and no starting problems,did have but cleaned pump in tank and fitted a good battery as advised on here,now perfect,so now time for a bit more get up and go.

I believe "TheBoy" on here has a contact who can get a variety of chips and is the preferred forum supplier..
Is yours an automatic or manual? Received wisdom is that if it's an auto with the original AR25 box, the gearbox will self destruct in fairly short order if you chip the car (there is one car on here with an AR25 and chipped that hasn't however) - if you've replaced the box with an AR35 or plan to do so, it's not a problem.

PM TheBoy in the first instance.
Many on here have the 'Plus 5' chip, which'll set you back around 70 quid.
The BMW lump is detuned to 128 BHP in the Omega - that chip sends it back to the BMW standard of 143 BHP plus 5% - so close on 150 horses, with vastly improved driveability!

Pretty much what others have said regarding g/box, you dont say what year your tractor is, if its an early one then youll probably find the chip change is a simple job of pulling one out & putting one in, however if its a later one the chips tend to be soldered in so youll have to have a socket soldered in place first, firstly identify your ECU by reading the black label on it, you need the last 3 digits to determine what chip youll need, i do have a +5 chip for a 427 here. :y :y

cheers everyone,sorry its a manual 1996 elite estate ,£70 sounds good value,where will i find the ecu.also one rear shock leaking,thinking of putting normal shocks on to replace self leaving has anyone any thoughts on this,will it improve it or what? :
-
The ECU is in the black triangular box next to the battery. If the rear shocks have had it the replacement ones will make a huge difference. If you not towing or carrying heavy loads then the normal shocks will be fine and a lot cheaper ;)
-
just checked 427 last three dig,on ecu so its simply remove ecu and then follow the posted instructions,what are the improvements of fitting say a +10 or more,only asking coz i don't know,oh unlucky alf how much do you want for your chip,is it new,n why isn't it on your car?

P,M sent. :y

It may not be that easy.
You will need to actually check inside the ECU to see if a socket exists or if the eeprom is directly soldered on.
I have chipped mine a few weeks ago and my 427 ECU did not have a socket :( :(
If your eeprom is directly soldered you will have to find someone to remove (de-solder) the existing eeprom and then solder in a socket. This is quite a delicate fiddly job so make sure to give it to someone with experience.
I am an engineer so decided to de-solder and solder in the new eeprom directly onto the ECU board..
Worked a treat ;)
Well chuffed with the extra power and torque. The best bit is the throttle responce in the higher gears (it was flat as a nun's chest before :-[)
Good luck.

Yes, and its now over 30k on the chip. I do have an AR35 on standby tho' ::) ::) ::)

I have seen some nuns with spectacular chests (but I'm not in the habit of looking) ;)
