6-71 blown Hemi going full lean on throttle tip-in
I've driven myself bonkers trying to figure this out and I'm sure its something obvious right on front of me.
First, this a 2006 300c SRT8. It's now a 6-71 blown 398ci with a progressive, dual Hellcat throttle body setup on top. The linkage to the 2nd TB is mechanical on a progressive setup that doesn't start until about 33% of the primary TB opening.
2bar MAP, 80lb Ford injectors, boost referenced FPR set at 43PSI. Cam is .598/.598 and 248/252 @ .050.
I've settled the idle AFR out and dropped the base timing to 14 around the idle areas to start. I haven't had drive time yet to work on the VE or spark tables yet. This is all in open loop. Fuel pressure doesn't drop during this problem.
When I give any amount of throttle quickly, it goes full lean. Slow raise of the pedal will get the RPMs up, but a good rev just makes it lean pop hard.
In the attached log, the instance takes place around 07:11:41.257 to 41.267
Huge thanks in advance for any help. I can't tell you how much I've already learned from the great people around here.
