Is there a way to program or use the empty pins on the ECU for a wideband? instead of using the A/C pressure switch.
Can't really find anything online, and wanted to know if anyone had done it. trying to tune a '98 Chevy with a built small block that my buddies dad had built.
it has a carb cam which draws less vacuum so the VE table will be all screwed up right? that's why we want to tune it
Any help appreciated
