Crazy Injector pulse

[uarperformance]

Hey Guys! Have a built 06 392 Charger. D1 Procharged. Has a very weird drivability issue! After doing a burnout it dies. No other time. if the car rolls through the burn out its pretty good. But do a burn-out and stop like at the strip. It dies and its acts and IS flooded. Have to crank and hold pedal down like an old carbureted I have a scan of it and you can see that at the 1 minute mark doing the Burn-out then dies as it stops. Injector pulse goes all the way to 23MS for a second goes back down and then back to 17ms. So what I am experiencing is real. I believe its a PCM issue but maybe someone else has a little light before I go spending looking for a factory PCM. Thanks is Advance

I would also like to know, I have the same issue, it also happens when I let off the throttle fast after a WOT run. 06 300c srt8 whipple here. Massive fuel dump and injector pulse width goes crazy and loses power or dies. I have read that enabling ?sensed map? could help and that this only happens to the 06 cars. Any confirmation of this info would be helpful.

Here is an example where I actually logged it. Changed to larger injectors since and it still happens. Very similar to what was posted above by uarperformance.20-05-31 17-20-38 weird cutout.hpl

its out of injector - 95% @6200rpm @ time stamp 5:19:15.130

I changed from 60 to 80 lb injectors after this log thinking the same thing, re-tuned and it still happens. Never cross 62% duty cycle or run out of fuel based on AFR, so i do not believe that is the root cause and something else is triggering a fuel dump.

could be out of pump too.. autozone loans a fuel pressure gauge .. tape the to you windshield and video a pull to see if it drops..
and post a log

Here is a log with a burnout and pedaling the throttle when I let off it floods the car with fuel but then restarted like nothing was wrong and took some pedal/air to get it to fire.
