Yeah, I'd argue there's a bunch he understands that you should be aware of. And I'm pretty sure he was thinking you were talking about using all of the L-jet/Jetronic to run the car- that's what I thought when I read it. He's familiar enough with the Haltech to be able to get my datalog from the Haltech to upload into the MS software to be able to view it to help me... And I think that if you drill down far enough on most of the modern FI systems, they're all kinda' the same- a couple triggers, some sensors, some data, some spreadsheets, some math- boom, car runs.
