Hi guys,
I own a 1992 Holden VP Commodore which has a Holden 5.0L V8 in it, the engine use to be controlled by a Delco 808 ECM, I have changed this to a P01 LS1 PCM.
The engine has been tuned using EFI Live and I am really happy with the tune other than a small issue when I stomp the accelerator pedal from a dead stop.
A majority of the time when I do this I see a lean mixture for a second (17:1) and it pops and backfires in the exhaust before the engine comes to life and takes off.
I have heard a few people speaking about dynamic fuelling.
Can someone point me in the right direction on what tables I can play with to try and eliminate this problem.
Its like the engine needs a little more fuel just on stomp to get the engine up and going.
On occasions when I stomp the accelerator pedal the engine will backfire in the exhaust and sometimes stall the engine.
I haven't tried it yet but I was going to increase the number on B3426 STOMP COMPENSATION to give me a little more fuel on tip in.
Do you think this is a good move ??
Any help would be greatly appreciated.
Regards Rick
