"Somebody stop me!!!" I'm amassing way to much EFI crap. Bought a pretty much complete Holley Commander 950, large bore TBI system for less than 400 bucks. I've been researching and slowly finding info on it I've found that it can be flashed to "Pro" by Holley and I "hear" the updated software is better, and that allows the use of a wideband sensor, which "ain't cheap." The system is not installed but......... I came up with an old Thinkpad, Whinehozed98 and the software runs. I powered up the box and successfully connected with the computer. (Had to make a programming cable) The "guy" over at the Holley forum claims you can't program them with the factory narrow band sensor. Any thoughts? Some photos of the system, and the software running. It's powered up with a bench supply, just the box itself, no sensors connected.
