I posted this on the MS2 section:
I have 2 cars running MS2. One is a v2.2 and the other is v.3. One is a 4cylinder Triumph, the other is a V8, 1uz Lexus engine in a TR7, both using EDIS and IAC. The v3 controller was originally built for the TR4A 4cylinder, and works. When we built the TR7 with the V8, we started out with the v2.2 board and got the car running, but it has electric fans, so I need control for them. I accessed the output ports on TunerStudio to configure those ports, enabled them, set parameters, etc., but it still would not work. I believe the v2.2 board is not configured for that, so I swapped controllers to the v3. The 2.2 will work in the 4cylinder car, or at least it will run and tune. I am not sure about the ports yet.
After putting the v3 controller in the 1uz car and loading the tune, the car starts and runs like it did. I opened the output ports tab in TS and got nothing. A window opens but is not populated. What do I need to do to fix? The v3 board was controlling the IAC on the 4 cylinder before....
What would cause this?
