I thought it must have been a bad cam choice, and I was also happy to ignore the whole notion of VVT spark as It seemed I could add advance through the main spark table anyway so didn't matter VVT spark table wasn't working because it was redundant.
Well Yeehaa...

Now VVT spark advance opens full phaser movement with torque plateau higher and longer, as expected, but not like this: WOT pulls on exact same 26deg main table advance plus 6deg VVT spark advance is 32deg on e85 @ 13.5:1 - torque pulls like a filthy monkey at 5900 [emoji205]
So all good, truly exceptional performance now.

I wish I could figure out how to tune with efi live, the hole Ben factor or Ben ltft has me totally confused!

Sounds like a nice setup you have we don't have e85 here

Where are you located...?

Have a read thru this thread (it is for LS1 PCM): 15236-Calc-VET-correcting-MAF-and-calculating-VE-(in-single-log)

I (me and statesman) am in the process of converting it for E38/E67/E92.
