Guys have tried to maxed the values for the 02s to disable closed loop fueling at idle. Is there a bug in HP or is there another table I cant see? The values ive added should delay the 02s for at least 10 hours and until the 02 reaches 4000F.
Is there another timer table we cant see?
The changes I made have delayed closed loop fueling for 5 minutes.
I haven't successfully got a ford barra, boss or coyote to maintain full open loop fueling before. ive tried idle only, full time and ive tried failing 02s etc to achieve it and nothing seems to work. im of the opinion there are several closed loop, open loop, delays, timers and switching tables in the background over ruling everything I tried.
That's all I have been able to do on mine too.Quote:

I have found that 5 minutes is enough time when your dialling in the injector slopes.
I think if you zero proportional and Integral it'll still be in closed loop but does zero correction.Quote:

You’ll know when the slopes are right because the car will behave, transition from low to high slope correctly and the closed loop fuel trims will be -8 to +8 for nearly all closed loop operation
