This is my first tune, its on my 2005 CCSB LQ4/4L80E. The cam is a Cam Motion 220/224 561/561 on 113, Pacesetter lt's , ebay cai , LC-1 Wideband, 3'' y into duramax catback , 4.10's and a value trac. The truck runs pretty good considering it's a heavy *** truck, but I fill like it should have a little more low end umph. I know the 80e has a higher first but I think from a dead stop stomp it should ruin the tires. Am I expecting too much or have I missed something in the tune??? working tune.hpt

new WOT run crew.hpl This is a few Wot runs I did this morning.

 

In about every WOT run, you have a nasty dip in timing. Did you get that figured out?

 

You are out of injector by 4500 rpm....do you have a wideband hooked up?

 

Yes I was hitting 11.5's so I changed my pe multiplier and now I'm around 12.85-13.5 and the IDC went down. I will get a current log today.

 

I think I had the AC on during that scan , for some reason timing will dip with the AC on. I did a new scan this morning so disregard the old one.

 

still need to add fuel 5000k+

 

Do you have E0% or E10% in your area?

 

Ok thanks, thats what I'm looking for. I went back and added to the PE mult in 5000+,that put me a little richer in that rpm range.

 

We have both, but I'm running E10%. The unbricked PCM is doing good, thaks again Kevin

 

im guessing your getting at the stoich value for e10? roughly 14.42...
