Peter,

Try calling Autotronics ( same people that make MSD), I've called them several occasions for help and they have always been helpful.

Howday All

I was wondering if anyone is familiar with or has any documentation
on a GM Integrated Processor Fuel Management system made
by Autotronics Control Corp Part # 5920.

It is giving me a problem in a commercial Van application.
The unit appears to control a propane mixer using closed
?? loop operation..

It plugs in a 350 tbi using a 8747 C3 ecm.

Now the problem. The Autotronics unit plugs into the TPS and Map
sensor. The original ecm connectors plug into the autronics unit
I would presume the signals are processed and then sent to
the ecm..

Big SES lite is on. Scan shows the TPS and Map signal are NOT
going to the ecm. No timing, TCC ect..

So I was gonna use an extra map and plug the stock ecm into
that. Not sure bout TPS.. Wonder if the signal output can be
run in parallel.. At least the ecm would be happy.

Thank you for any help anyone can give
