I use HPTuners.

And as far as the fuel trims you should have seen it with some 100% gasoline I found at a local station. I have tuned it with the common fuel available around here that has about 5% ethanol. With no ethanol in the fuel, the fuel trims drop to -10%. Just goes to show you how much worse MPG is with ethanol gas blend.

Not just E67's. That's the case with all the LS based engines. The old LT1 engines would add fuel at WOT if fuel trims are too high. But the LT1's would never subtract fuel at WOT.

I don't believe that's correct? I know that they will add fuel if the trims are positive, but I've yet to see one that pulls fuel if the trims are negative.
I don't think I've seen commanded EQ be affected or IPW?

I remember the BLM locker tool (that I think Jordan Musser wrote?) that used to lock the LT1's to 0 trims at wot.

I Think Christian Millard wrote it, I'm sure Jordan was using it back in the day. Haven't seen Jordan in a few years now. But anyway every LS car I have tuned will go into negative LTFT's at WOT if the tune is rich.

OK I take that back. I went back and looked at some old tunes of LS6 and LS1's and LTFT's at WOT are always "0" or positive #'s. But the E67 will pull fuel at WOT.

[ZO6 Bryan]

But I did find some scans of my TBSS with an LS2 and E40 PCM where it will pull fuel at WOT.

That only matters to some of us,,and these motors if tuned correctly and if not beaten to death are all most built proof..
He has not gone into the motor yet,and everything can be R&R again really easy,if needed...

Correct I am sure. I know that i asked FASTLANE about that right before i dropped it off there,and they gave me the number to the dealer they use to purchase the GM vehicles for their customers who are wanting something with a warranty.Anyway he told me that if I had any engine related mods done to my ZL1 that it would not effect any coverage on my car what so ever...plus all of my work is covered under FASTLANES warranty ,as well are the parts covered by LPE warranty since fastlane is a AUTH installer,etc....Thats another reason to pay the correct shop to install the parts,instead of doing it at home. But to be honest before I became wheelchair bound i normally did it at my own shop or at home nor caring about the warranty..

[EvilZL1]

So, how can you keep your warranty? Have you been to Memphis Motorsports ( I think that what its called) track in Memphis/Millington?

[Mutant Racer]

Nicely done Bryan!
