Testing Automotive ECUs

Dave you are amazing. I've never had the design skills you seem to. I've always been more about repair, or building something someone else came up with. On a side note, "all this stuff" on EFI frankly amazes me. I can remember "we all" were depressed when EFI started to come out, as it was obvious the OEMs had stuff "locked up." This of course was before the internet, so there was no great amount of hacking, sharing, and modification. And, it turns out, you cannot believe much that showed up in "Hot Rod" magazine LOL
