Dan you're not going to like this but that Hilborn has a VERY crude control system using very few inputs (2) and cannot be as efficient as it should be.
Thanks for the information Abe, it's been helpful. I looked at the wiring schematic and noticed that there were no 02, air inlet temp, or manifold pressure sensors required for the Rally System. Question for you, it's the computer module that needs all of the sensors (correct?), so your not talking about the performance of the Hilborn injectors are you? Correct me If I'm wrong, but don't the injectors only need to be given commands for when to "inject" fuel and how much fuel (air:fuel) to supply? If I'm correct, then can't you use different computer modules with compatible injectors?

I'm considering the computer and injector systems to be independent components.... I guess I'm trying to ask you if it's possible to change the computer component depending upon the level of "tuning" you want to perform. If I want "basic" tuning now, can't I trade up to a more sophisticated computer system later?
