Dieseling condition for 2007 M6 with e-force?
Anyone getting dieseling at shut off? I have it and we're trying to figure out if this has happened to anyone else or if I'm just a really lucky guy.

Well, that's why I'm asking.
It didn't do it prior to the install. Now it does. I'm looking for ideas on how to find and fix.

Yup. Old carburated cars could "diesel" because the carb would keep letting fuel in no matter what... On a modern car shutting the ignition off turns off the fuel pump, the fuel injectors and the coil packs; it should be completely impossible for it to diesel...

Edelbrock #1591 kit on my LS3 since the end of this past March...no dieseling here. I've tuned at least a dozen LSx motors and never had one diesel. As mentioned above, on shutdown the car kills the fuel pump, the coils and the injectors....strange

... none on my 1590! I did notice that happened once when they were tuning it... not sure why but I heard it! Doug at ECS kept tuning and when he was finished there wasn't any of it. Some how it must be related to tuning.... I would call Doug at ECS if you can't get it stopped..... I'm sure he'd help your tuner!

Car needs to be scanned and see at a minimum what fuel trims are trying to do.

He needs to make a road trip down to Ian at The Tuning School and get it squared away.

He was one of the guys who had problems with the LS2 tune. IMHO the guys who worked on his car lacked the necessary expertise to set up his car properly on their own. Who knows what is in his ECU!

I think that's a good WAG! When mine was first started ECS had the stock tune.. never used Edlebrock at all. I remember hearing it's running SUPER rich from the tuner.. before he started making adjustments. That's when it dieseled.. BEFORE he started doing all this adjustments!

Even if the BAP was commanding full power to the fuel pump no matter what, you'd still not have a running engine since that requires the PCM to tell the fuel injectors to fire and the coil packs to produce a spark. No injector signal = no engine running. No ignition signal = no engine running either...
Not to mention the fact that if the BAP really didn't shut off it'd burn itself out.
