ITBs w/Motronic ECU, cam choices for 3.2 Carrera rebuilds
Do ITBs gain anything over a stock Carrera intake if the Motronic ECU is retained?
Cam choice is what Im really curious about. I know I cant use anything hotter than a 20/21, 964, or 993 Supercup cam with the common plenum carerra intake due to fuel reversion issues. Can the Motronic ECU be chipped to use a hotter cam like a GE40, GE60, or GE80 if ITBs are used instead of the Carrera intake? Or would I need to go to full engine management if I wanted the hotter cam?
TIA
