Art, you heard wrong. FAST makes one with traction control, but it is a different name and color box, and they tell you it's not legal for NHRA. Besides, if you need that you have serious problems anyway. I remember David Nickens and MSD testing his pro Stock car at Baytown with traction control, and the best they could do was run the same, that or slow down. That was back when everybody was that crying Greg Anderson was using it when he had over 1/10th on everybody. They came and got Mike Edward's MSD box every time he qualified in the top half for a while. NHRA would bring them an MSD box and wiring and make you swap with them. The guy on the golf cart would drive off with this geeky looking little guy looking over the program loaded in the box they just confiscated. Nothing there. Anderson kept killing everybody for a good while. Most everybody's (at least most everybody fast) automatic cars dead hook anymore anyway. Traction control on Stockers and SS cars like we run ain't going to do a thing for you.
I'm sorry you had a bad experience with trying to tune your FAST ECU. If you were closer to me I would have helped you with it. They will idle and run just fine. I work with them all the time. MSD? I often wonder if that stands for Must Soon Die. I've had some reliability problems there in the two short years I have used it.
I have never been asked what EFI system I use anyway. I use the FAST XFI, but noody has ever looked or asked. Maybe if I were faster?
