setting B3618 PE AFR with cam and supporting mods

That concerns me there is a fuel system problem. it has a walbro intank pump but i guess anything is possible.

No, not necessarily - I noticed that the injector flowrate table slope is kind of steep - that is why I questioned where the data came from in an earlier post. That will effect the shape of the VE table - but it doesn't mean that there is a problem. Go ahead and log the tune I posted...

I tried to hit as many as possible , hopefully the throttle was smooth enough for most of it.

Its coming along - give this one a hit - do a little longer WOT pull this time too.

Yes, during tuning, disable DFCO to avoid the lean jump on decel, and set B4105 to 450mV in all cells (later GM calibrations do this also).

Sorry about intruding here, but when tuning the VE table in speed density open loop, should the STFTs be disabled for that?

Yes, you want STFTs and LTFTs diabled.

tried some more wot. I hit the limiter once.

and thanks again!

Yes...

disable all sources of trimming/correcting: CL, LTFT, STFT, SOL.

also disable the other source of cylinder air: MAF.

[BLK02WS6]

Go ahead and hook the MAF back up and load this tune. Add MAF frequency to the pids for logging. Don't hit it too hard this time at WOT - just one quick pull up to 6000 rpm to see where it is.

I will give it a try tomorrow night. do you want a full log or just the run to 6k
