Around 2 weeks ago i installed a set of toyota cops. They ran fine for around a week untill i touched the rev limiter one day.

After that point i've had a problem where under high load/in boost over 4500rpm i get a very bad misfire and backfire from the exhaust.

Flatshift/launch control is not enabled. This is a picture of the ignition settings im using:


Could it be a case of a bad cop, or is the a different ignition setting that may solve it?

Any ideas would be appreciated.

Datalog please

 

Only a couple of short logs, but i the problem was pretty pronounced when i logged them.

I'm only seeing a misfire in the first log, at partial throttle, while there is no misfire apparent during WOT?!?!

 

hmm, ok, il take another tomorrow. It seems to be during boost and i do get a slight misfire at very low revs in 5th gear.


Any indication of what it may be?

Thanks
Mike
