V2 BBL Flakieness

I'll give it a shot... I'll have to take my truck for a ride tomorrow after work.

Thanks.

Any thoughts why this never seemed to crop up before? I don't recall seeing this kind of behavior prior to the 2.07.xx firmware.

We're having that discussion at EFILive now...

* Looks like Bosch (or GM not sure who) changed the PID definitions that were originally defined for the LLY to a different format for the LBZ. THe EFILive software is not configured to handle that change (yet).

Go figure. If I had to guess, I'd say it's another "Boschism". From hearing Ross talk, Bosch does *everything* wierd relative to everyone else (What's with all the xxxx DTC enablers, some of which are set to "Non-Emissions, MIL On" ? That oddity is new for the Bosch ECM's, not to mention the total lack of any rhyme or reason to the order of them . If one of them trips, are we going to get a Pxxxx DTC? ). Take IAT, for example. In virtually every other PCM, AFAIK, IAT is measured at the MAF. With the E35, IAT *is* measured at the MAF, but for whatever reason, your definition of IAT (I'm assuming a "standard" IAT definition) is actually polling IAT2 .

I'll give the new pmm a shot tomorrow.

I ran my truck for a few minutes to check out the logging, and the data appears to be sane... But I'm not sure if FRPADES & FRPACOM are actually logging anything, since their values didn't change at all during my time logging...
