Great. Thanks.

I need to do a 4l80e segment swap for an 04 Silverado. I also need to make it a 3 bar SD. Should I do the transmission segment swap first and then the 3 bar SD or does it matter?

The spark table is just roughed in for now. I'll smooth it when I can start making WOT pulls.

I'll post a log in a couple hours. I appreciate your help.

It only makes 4psi and it has no problem making that without issue at part throttle. REP only happens at WOT.

The car did see WOT and go into REP in that log. I'll add TPS position and post...

Randomly, but not every time, it throws P0103 Mass or volume air flow and P2544 Torque management request signal A.

It goes into reduced power as soon as it sees 100% throttle. If I hold throttle...

I have an 05 C6 that is all stock except a turbo. Stock sensors, fuel system, everything but a turbo. Waste gate is set to 4psi.

I can roll into the throttle and make 4 psi. If I got to WOT it...

That makes sense to me. Now I need to reset my brain and scanner from AFR to lambda and figure out the lambda error pid.

Thanks.

Ok. So if the stoich table is 14.67 to 8.97 the multipliers like PE will work and log in lambda and make adjustments to VE and MAF as normal?



If that method is used how do you log and tune VE...

I'm new to flex fuel tuning and trying to tune an C6 with a fuel sensor wired in. Alcohol content is reading 78% and everything seems to be working proper.

How are you guys setting up the scanner...

That's what I was thinking. Thank you for your input. Did you happen to look at the attached tune and log? Thoughts?

I have my drive tune pretty good and I'm ready to start on the WOT tuning. I just want to run some things by more experienced tuners and see if I'm on the right track.

I am commanding PE at 13:1...
