Not much help with yours @
ztan but more of a question for those who are good at discovery.
Been trying to work out why the throttle closes under WOT and am doing some digging around. I don't suppose anyone fancies digging into the throttle angle routines. It's definitely nothing to do with requested angle, however there must be something that causes this. It seems fairly uniform between FI and NA cars too. I've tried testing Requested torque and calculated tq tables but nothing there has yet made any difference.
