Thread: Top Swapped L26 hpt file

Any of you guys have one that you're willing to share or at least some base tune? I am ridiculously far off.

What have you done so far? what car? what year? injectors? maf? pulley? blower?

Yeah it would have made sense to include all if that info haha.

Blended inlet Gen V
1.8 roller rockers
42.5 injectors
Heads ported just enough to smooth out casting flaws.
Cold air fenderwell intake

2007 GP L26 bottom end

Stock MAF

4.0 pulley

2007

I was using the MAF table from and 05 GTP and I fixed my injector tables last night.

Above 7000hz on MAF frequency I lock in Power Enrichment. Did 10.0:1 to be safe. Writing with 11.0:1 right now.

And my battery craps out on me. Didn't have that in my budget. Damn.....

Yes I do

PE entry should be about 25% throttle. Other than that make your commanded PE vs coolant about 12.5, it should command about 11.5 on the scan at that point assuming the rest is stock.

That doesn't seem too lean? I'm commanding 10 now and seeing 13.2 on the wideband and some knock. I had PE at 30% too. May try 25. After tonight I'm giving it a break. Commanding so rich is really sucking down the tank.

Its not going to make a noticeable mpg difference...

I know, but I still have to give it a break for now. Still knocking all over the place. Using AL 104 plugs. Maybe I'll go to 103s this weekend.

You put L67 timing in correct? Start out with about 14 degrees or so if you are having issues.

No I put in L32. Used file from an 05 GTP. VE table scaled for L67 MAP sensor that im using.

Do you have HPT? I think I can upload a scan file here right?

Nah just tried. I don't think I can upload that here.
