Force open loop just at idle

[pkincy]

Everyone is giving great advice on how to go to OL.

However lets step back a second. With your cam you don't need to go there.

Simply search the threads for how to idle tune and follow the directions carefully. Your cam is way small compared to some others that run just fine in CL.

Add some (maybe a lot) of timing in the idle ranges to rebuild the cylinder pressure that the overlap bleeds off and than do the airflow stuff and you will have it purring like a kitten. Well maybe a little lope due to the 112 lobe centers but it will be just fine.

Now reading the idle tuning threads will make your head hurt for a while (at least mine does) but it will all come together pretty good.

I recall a pretty good sticky on one of the other fora on this from last year. I think LS1Tech.com. Not specific to EFILive but it gives all the basics. Add the threads in here and you will be an expert.

Thanks Perry, your right that’s exactly what I’m doing. Got a wideband so I could better judge the mixture, Started playing with the O2 switch points and gave it a bunch of timing. Tamed that cam right down. Still working on it but I’m close. Thanks guys
