Trophy #267
As some of you may be aware, I have been having issues with a group N ecu Im trying to put in my late mk2 172 (CB1N late 04 reg'd motorpoint jobbie)
I have a spare 172 ecu bought from 16vJON on here which to the best of my knowledge is normal for a mk2 (mk1 ecu having 256k flash, mk2 = 512k flash) and should work on my car. pmurray & bellautos have been assisting me with my testing and all attempts seem to show the same effect and lead me to believe that my hardware is unique in my car.
My problem is that I believe my car is unique in that is has a 182 ecu on it (possibly plus other 182 bits) , hence my ref to a mk 2.2 and is causing some strange things to occur when the spare ecu I have is connected when programmed with a group N software.
So far issues I have seen are:
Coolant needle on dash does not move - stuck at bottom
Radiator fan on constantly even with keys removed (poss fed from ecu or by product of incorrect temp reading in 1st place ?).
Does anyone have any info on the differences and any assistance ?
