Hi, as the title says, I want to load a P30 program to an automatic P72 OBD1.... The main reason I want this is that I have a fully electronic automatic transmission in my car, mated to a B16... Right now, my car is shifting at about 6800 RPMs, since this transmission is controlled by a separate TCU, because my P30 cannot control it.

A few months ago, I had an automatic P72 ECU installed in my car, and it was controlling both the engine and the transmission, without the need of an external TCU.

So, I thought that if this could be done, I could use my P72 (with P30 fuel/Ignition maps), and take advantage of an increased redline...

Many thanks for reading,

Roms are usable on all 66207 ecu's. Just enable/disable sensors that aren't on the host ecu.

theres a listing of ecu's and models/engines found in... just download the rom; export the tables, then "File->new" choose p30, import your saved tables, and you have your basemap.

you will probably need to check AFR offset if you change settings like disabling the o2.
