Re: Motor Control System Failure after remap
Thanks for the replies chaps.
The battery is OK Nev.
Pud, is it really a good idea to plug the EGR valve? It must perform a function which means there would be other side effects, surely? I understand and wondered about the sticking vanes thing, is it a big job to pull the turbo apart to check/clean?
Nomes, I spoke to Augusto some weeks back, he suggested it might be the overboost sensor - I had this changed by Jamie Porter last Friday and there has been one MCSF since. Maybe it has settled down now?
OA and AL, obviously, turning the boost down is an option - but the remap is not particularly radical, the 1.9 will easily go to 200bhp and 280ft-lbs according to Red Dot. It's a bit frustrating to say the least.
Would the diagnostics actually tell me how much the overboost is, or just that it is overboosting? If the amount of overboost won't do any damage, is there any way of making the ECU think everything is OK?
I don't really understand the relationship between the ECU and the 'Map', are they separate entities that talk to each other, or is the Map inside the ECU?
Also, I'm wondering why everything was hunky dory for a whole 3 weeks, only then did I start getting MSCF's?
