Yes Stef, I agree with your potential explanation. As I said previously, I was surprised to hear that it tied into the motronics. Eric pointed this out, and I spent hours reviewing the wiring diagram. Being I have the schematics on CD and downloaded, it really can be difficult to follow the flow without printing out multiple pages. I also wondered if it were possibly some sort of over rev protection being the car is drive by wire. Anyway, my initial assumption ( incorrect) was it the switch was a simple starter lock out. Also when I started the car without the TCU installed, I received no check OK, and a solid check engine light, although the car ran perfectly. When I reinstalled the TCU, all functions returned to normal, and the CEL went out.
I am installing a factory "sport exhaust" which comes with new motronics, which are transmission specific. Installing manual trans motronics should eliminate most troubles. I am very excited to get this done. I am more concerned with converting my friends 430, as I am sure the ediff will complicate things a bit. The one encouraging thing is the factory made these cars both ways, so it will be reasonably possible. I expect to start posting pix of the details soon.
Thanks again for your input.
And yes Taz, I was considering the fact that you pointed out about f1 starting in gear. That seems to occur by the pump applying pressure to the throw out bearing which disengages the clutch, and satisfies the TCU to emit a signal to the start relay.
I will say, I am having a lot of fun learning the inner workings of this car. I have learned things that I didn't even intend to!
Anyway, I do appreciate the help and comments from everyone. If it were not for the people I have "met" thru these forums, my project would be so much more difficult!
