here is the deal, this is a track 07 Z06 Vette which will get a Kinsler ITB system with custom SD OS.

I do not need any IAC, cruise control whatsoever, and thus the idea what will happen if PCM just sees the TPS sensor with all TM, TC and all reduced power parameters removed. Changing to piggy back Motec or LS1 style PCM not really an option as some creature comforts will remain and Vette still looks stockish on outside and should stay that way. However, keeping E38 in place and run engine off an LS1 PCM would be an explorable solution too, that should keep all other CAN bus nodes happy.

what will happen, anybody tried?

asking this here as even Bill is not sure if it would work or not
