Hey everyone I’m running the tephramod V7 for rom code 90550001. It’s currently set up for load based boost control but I want to switch over to ecu controlled boost. I have an omni 4 bar map sensor that I use to log boost which works great. I searched and couldn’t find anything about ecu controlled boost for rom code 90550001. If anyone is doing this please point me in the right direction.

 

Mainly just commenting to follow the thread, I don't have anything useful to contribute sorry.

Mine (90550701) is still set to load based because I could never figure out how to setup the ECU to use my 0-5V MAP signal.. I fed it to the relevant pin (the exact number I have forgotten). Never went past that point.. I don't know how to setup l the MAP VE Voltage tables in the ROM, or if theyre even relevant..

Alf gear based boost control doesn't seem to work even though I calculated the rpm/mph values too.. (25psi in fifth gear is something I try to avoid).
