Thread: Identifying mod ECU

2/ Would a saving of $150 be worth the effort buying a second hand unit from a wrecked TD5 or would I be best getting the ECU specific for mine?
why? is there a problem with the current ecu?
Thanks

i'll give you te third question for free

cheers phil

As Phil says its not easy. If you have an early D2 and it has a late part number ecu (NNN0000120 from memory) it may have been changed, but not necessarily chipped, but to tell from the outside wont be easy.

Other things may point to it, such as if it has had the EGR removed, or a larger intercooler fitted?

Driving it should be the easiest was of telling. Does it feel quicker than you would expect it to be?

If you can get a spare ecu for $150 I would buy it just as a spare.

Thanks ,

No nothing wrong with my ECU.

I was offerred an apparent mod. ECU from a wrecked TD5 for $500. saving roughly $150 on getting one from TRS

I cant drive it to see.
No. There is no EGR mod or intercooler mod either.

Seems to me from the replies that maybe I should just get my ECU modded rather than take a punt the unknown.

Thanks

The injector codes (at least) would have to be set to the same as yours, which is probably going to cost you money, so the apparent saving is less.
