Which wideband are you running...?
Which wideband are you running...?
It seems to me that your MAF is lagging by about 1 second... post a pic of the MAF duct/plumbing.
It seems to be getting richer because either of COTP (cat over temp protection mode) is enabling...
( PPM has the same commanded fueling but is not enabling since it's MAF/TPS/ECT enablers are not reached )
Yeah,backing up what Joe said above(I hope!) at frame 140 your idling at 1000 rpm with 0% throttle and ~27 degrees timing. At your ECT(194F) your B4603 is commanding 800 rpm. Then at frame 160 idle drops to ~700, timing spikes to ~40 degrees (I imagine from Stall Saver) . For quite a while after that RPM raises all over the place, all without any pedal.
after another glance without playing ten thousand questions in my ear(kids), I see your Stall saver is zeroed out. And even though theres no pedal signal, the vehicle is moving. so either your rolling down a hill in gear, or your pedal isn't properly registering.
Other things I see as weird: B0108 and 7 are zero'd. I would think these need a proper value in order to use the idle airflow tables. I'm not sure but I think you may be idling based purely on the VE table.
-Oh, and I'm not a professional tuner, yadada....
some of the things I see may just be attributed to the 90mm TB and ported intake.
Do you have the stock tune that this PCM started with...?
hopefully this answers all the questions.
i do have to get out and do another log for driving, just out for the weekend and trying to install cats next weekend. after my friend helped with the maf scaling, things are better, and i've worked on the idle to get it down lower. i think that was the cause of the high map values.
log 38 was the last time out driving with the new maf table
log 41 is the idle where i'm at right now
i have a aem uego wideband
