I need it for initial start because it is already scaled for my injectors and Maf, and i need to pass emissions in Ct. I haven't been able to find any conclusive info on this. I know that the cam sensors between the s20 heads and t20's are in different locations. I will be using ia performances bulkhead and engine wiring kits for the avcs, What will i need to do to make this work? My usdm ecu already has the tgv codes deleted and forced for readiness. I guess my real question is how can the usdm ecu work with the different cam sensors? Please help. I'm confused lol
Should be no trouble at all I did the same thing with mine years ago after the swap I was waiting on an engine and avcs harness. I used my 05 usdm ecu tuned for the ej207 for a few weeks with no issues.
