I do recall @ steve99 saying that I should go back to petrol to dial in my MAF scaling, but I've also heard that the numbers from the perrin site would get me in the ball park. Currently, I'm sitting at -10% at idle, and -7% cruising at 45mph/2500rpm... tips? |
yep the perrin scaling is ok but if you want the maf scaling good enough for +/-5% your going to need to do your own scaling.
some cars it will be closer than what your seeing, their is a bit of variation in maf sensor between early and late model cars
you can scale maf of E85 but you need a consistent blend of E85 to do it else your trims will be wandering around with changing E% as well as maf scaling and temperature changes so you will just chase your tail.
