Phantom Rev Limiter On Hard Accelerate
 
1 Attachment(s)
I get a "pop pop pop" when I accelerate. I've attached a screen shot and my datalog if anyone can decipher it and fill me in on what you think i going on. Notice around the 30sec ish mark...that's the acceleration. I'm in 3rd... accelerate pop pop pop, 4th... accelerate pop pop pop, 5th... cruise with traffic.

My guess is throttle position acceleration enrichment or fuel acceleration enrichment.

Thoughts?

I think you're on the right track. Your accel enrichment is putting quite a bit of fuel in, AFR is dipping deep into the 10s, so the plugs are probably having a difficult time igniting the mixture. Try pulling some out, should clean it up.

You're also showing 105% on your total correction, so something else is contributing to the rich scenario. Go to Fuel Settings->Fuel Calculations Summary to find out what it is.
