Stumbling and Bogging from dead stop in 1st Can't Launch or Burn it up?? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

ZL1 Start from dead stop, Stumbles are Boggs .. Can't do a burn out.
Traction control turned off, Start from first gear punching the exhilarator car stumbles nearly bogging out .. cant do a burn out.. then picks up and go..

Noticed i have this issue after i did the ecm fuses 5, and 20 pull.. before that my ZL1 could put down the pwr to the rear and smoke em up .. . now i'm regretting i did the fuse pull out of curiosity. I never ran anything less than 93 octane fuel .. i were one of the few people that probably did not need to do the fuse pull but did it anyway out of curiosity.. anyone have any ideas what''s going on.. could it be something else coincidentally that developed after i did the fuse pull could it be have a vacuum leak some where?????

No, the computer is programmed to pull 2-3 degrees of timing with a WOT start. Why, I don't know.

How many miles are on your car? I speculate that the ECM fuse pull probably also wipes fuel trims as well as the knock retard table. It is possible that you may need to drive the car normally for a bit to let the fuel trims relearn.

I can't think of any reason fuse pull would do this it actually woke my car up.

datalog is kind of what you need to see. hold down for 7 senconds turn the stabilitrack and t/c off.

the car should do a burnout.

even if the car pulled 2-3 degrees of timing it would still melt the tires down from a dead stop. it has 580hp.

if the car is boggin something is stepping in or the car is not running propperly.

The very first time I really ripped on mine with about 200 miles on it it did the same thing. I drove it and put some miles on it and I haven't experienced it again. I read a thread on this same thing a long time ago and it was explained. I jus don't remember what it was

I took delivery at 19miles; at 200 miles I felt all 580horses burning a hole in my wallet smoking up the rear tires. Dang wish you could find this thread..

Folks pls keep this thread alive... I bet someone out there knows.

I heard from my tuner after a fuse pull it puts the ecm into the low octane table and it takes a while for the ecm to "catch up". Drive it more and it should learn and work itself out. Double check your fuses too. Maybe disconnect the battery for a few minutes then reconnect and drive...couldn't hurt.

I did the fuse pull on mine and did not have any issues. The car actually feels a little pepier. Still have to problems breaking the tires loose shifting through 4th gear.

which fuse do you pull? And how long?
I thought the fuse pull puts it high octane?
