15 Chevy SS, manual transmission,, LSA supercharger with 2.55" pulley, BTR PD supercharger cam, 60lb injectors, stock MAF. I have dual LC2 widebands and created a calculated PID that compares the average of both banks to the commanded AFR.
I have a fair amount of tuning experience, but none with the e38 controller and none with efiLive.
Installed the mechanicals and everything is working well. I know I have the correct fuel injector data.
The tune is far from complete, but I have set about dialing in the VVE and MAF and both are to the point where the error is within a fairly small range.
With the car in VVE only mode it runs very well and goes to wot nicely.
With the car in MAF only mode (B8024 and B8025 set to 0) it runs very well (although it tends to run very rich at idle on initial startup) and goes to wot nicely.
With the car in "normal" mode - VVE and MAF working together factory style it runs very well until you go WOT and then the AFRs spike very lean - very lean.
Attached are the 3 latest versions of the tune (I disabled LTFT on all of them):
Here is a scan showing the AFRs going sky high:
I know I am missing something, but I am not sure what it is.
I appreciate any advice. Thanks.
