2 quick questions...FC coils and OMP
 

I'm looking into putting an rew into my 1st gen. I need to know what all is needed to run fc coils and cas. Does this work with the stock ecu? Is it simple as cutting the connectors and attaching the fc connectors? I've looked at the wiring diagrams and it seems like that's all it would take.

And as for the omp...what kind of signal goes back to the ecu? Is it a voltage, resistance, does it count the rpm??

I'm not wanting a race motor so the extra $1000 for a power fc isn't really worth it to me. If it can't be done with out going stand alone I'll just go back to a t2 motor.

Any help would be appreciated. thanks.

The OMP I know is controlled by the ECU on the S5's, if you use an s4 OMP it is mechanical, therefore not controlled by ECU.

As far as the coils, those are definitely controlled by the ecu. If you need more information take a look at the factory service manual for the FC.

Can't you just run a distributor on the REW from a 1st gen? That should solve your problem.
