oh, I don't know.............. 5000 things running in the background, shut off the O2's and they still affect things, sportsmen vs pro key, hate that TAU deal (or whatever it's called). Every dealer in the Sacto area that I knew of has dropped them, as well as a dealer I know in the Bay Area.
I've tuned FAST, BS3, Gen VII, Holley 950 Commander, Factory GM LT1 with a prom burner, GM gas and diesel computers with HP Tuners and EFI Live, Ford Lightning computer with SCT Racer Pro, MEFI 4, and probably others I've forgotten.
By far the Gen VII was the most frustrating to get up and running really well. Actually I couldn't get things perfect for a friends Procharged small block so he paid two Accel dealers several hundred dollars each to tune it; both tunes were way worse when they finished with it, in fact one of them made 700 rwhp but you couldn't even drive the car back on the trailer to get it home. Had to load my tune back in (maybe I'm better than I think!
) After all that my buddy sold the Gen VII and bought the old FAST unit, immediately ran 100% better.
I am not dissing the system, it's more than capable. But I'll stand by my statement that it's much tougher than any other I've listed above to get tuned, at least for me. I'm just a hobbiest, not a pro, but I have a fair amount of tuning experience with n/a, twin turbo, blowers, diesels, etc. I know Accel had huge issues initially with EMIC's being awarded to people that should not have been able to get them, but there's still some pretty good tuners back then that gave up on that system.
Those two dealers I mentioned above dropped that system long ago, and these guys have been tuning for a long time. I've heard that the Accel has been "dumbed down" so maybe what you get now is not nearly as quirky as what I tuned. My experience was from when it first came out several years ago
