Hi Guys,
I've just been out and done my first proper logging as I think something isn't quite right with my car. (Remapped LC with induction kit).
I'm getting this error frequently:
But can't find any split hoses and the DV is a new forge one. So, this led me down the broken MAF route.
I've posted my results below, and I'd be interested in knowing if you think there's something amiss.
The peak air mass is 162 g/s - does this sound reasonable? From what I've read this might be under a bit, but doesn't sounds broken.
Also - would you expect the actual boost to read the same as requested at the time of planting the thottle? I assume that the turbo takes a while to wind up to full speed, hence the difference at the beginning of the run, but I would also expect the engine to ask for less boost at the start?
If I use the g/s muliplied by 1.31 I get a bhp of about 210 bhp. I would have expected this to be a little higher.
Here's a log of 003 & 115
Any pointers would be gratefully received.
Is there something else I should log as well, perhaps timing pull?
Cheers, Will
