EFI Bung in head update

Thats no $800 van, he has that much in the transmission alone. I have read up on it. Still a junkyard hero though! Gonna get some more work done tomorrow. Got the MS stimulator built and running, but this stupid serial port connection issue is driving me nuts. I got 4 computers and none communicate with the MS1 or 2 upgrade, nor even loop back to themselves. Even trying linux(s) on my old HP laptop that has a serial port, others need USB gabage. MS3 has USB built in, thats a great option. I have been planted in this ceat for 3 days trying to get the serial issue solved. Good times! Im in the garage tomorrow :-)
