    EXT.WO2LAM1 looks noisy...

    do you have the CALC.AFM1000 analog calc pid file I made for you a few weeks ago (was it you?)(yes, it was you, I see the pid CALC.AFM1000 selected in your log file).

    Well Bret's been using the SAE.LAMBDA vs. EXT.WO2LAM1 for all the tuning we've been doing, I hope it's accurate! haha ... could the noise be because of the high channel count? I've reduced the Channels as directed, will do some drives tomorrow. BTW, I'm using a Innovate SCG-1 Wideband/Boost controller with the serial connection.

    Can you post some previous logs of SAE.LAMBDA and E38.AFRATIO, I want to compare those two pids.


    With E38, to get faster sample rate from the wideband, we've come to the conclusion that you will have to use analog.

    I guess I'll have to go in my dash to pull the wiring out haha

    Ok, thanks, your log shows SAE.LAMBDA working correctly.

    Why does the SAE.FRP show so much variation...?

    Is your FPR manifold referenced or unreferenced...?

    we did bump up the High numbers under fuel pump controls. I think it follows the PE mode? It did work though

    Post you tune file.

    If rail pressure varies (and not with MAP), then I'm wondering how the ECM determines the IFR...

    Here ya go. Maybe you can figure out what's been making us scratch our heads for months, haha. The point between normal/PE and lo/hi fuel rates and etc. have been a nightmare to deal with. And somehow there's a point where timing just goes through the roof during part throttle pulls.

    The IFR table uses delta pressure... calculated from rail pressure and MAP.
