Hi. I'm not a tuner, but I have a friend who is very proficient with tuning the LS1 motors with EFI Live and he and I have been tuning on my '08 Sierra Denali for over a year with it. We have read Swingtan's tutorial and want to dial in the VVE, as we can't get the AFR any higher than 12.0 to 12.4, even if you command a 12.8 in PE.
However, I have read the warning pop-up when you open the VVE tables in the tune tool that says:
"Variable camshaft positioning is not currently supported in this version. DO NOT use this software version to tune controllers/engines that implement variable camshaft positioning."
Does this mean that we shouldn't be using EFI Live to tune my truck? If not, what version should we use? My truck has the L92 w. VVT (I have in fact changed the cam to a Mast Motorsports VVT "Truck" cam)
I mean, we have been using this to tune my truck for over a year, to retune when I changed the cam, converter, gears etc, and have even tweaked the cam phaser a whole bunch, so what the hell does this mean??
The truck runs good, just a bit rich @WOT and we want to try to tune the VVE, but now I'm worried.:help2:
Here's a log that we have made recently, after I changed the gears to 4.10s:
Any guidance input would be appreciated.
