Have any body run a fuel only haltech with the stock ignition in the FD?

Do you have to remove the wire harness even it you dont need it?

 

do you mean swapping a FC front cover on it and using that CAS?
what is it you are trying to do? are you running a F9/F10?

 

I think he means just using the Haltech as a fuel controller and then using the stock ECU for the ignition. I don't know if the FD will like the stock injector connectors not being connected to anything but maybe you just have to jumper them or something.

Do you have to remove the harness??? No, you can leave everything in there if you really want to

 

Yes I was planning on leaving in the wire harness to power the ignition circuit, for right now the only thing that the stock computer is powering is the two primary injectors ignition and oil metering pump, that brings me to the next question:

Will the oil metering pump still operate and where does it gets its signal from? crank trigger?

 

Pull the FI leads, install 15-ohm 20W resistors over them and be done with.

Wire the Haltech in parallel with the stock ignition input and TPS.&nbsp Wire the Haltech to handle just the fuel injectors and the MAP sensor input.

Don't touch anything else.

The stock ECU will handle everything but the FI.&nbsp The Haltech will merrily run just the FI.
