I asked Accel a couple of years ago about adding "self learing", the answer is simple.
Most EFI's in this class use the same capacity boards, they'll only hold/do so much, period. Big Stuff has more dataloging than most others out there, but did you ever see their transient fueling tables? They suck, I think there's 3 of them. FAST now has self learning and some other "new" stuff. But again there are other things they had to leave out. Accel doesn't have self learning but has more transient fueling tables than anyone, and have you ever used their nitrous tables? I don't think they get any easier, enter the pill size and bottle pressure and it does the fuel map for you, and it's damn close.
So what do you give up? In the case of Accel, do you give up the transient tables etc that imo make it drive better than anything in this price range, or does BS3 give up their datalogging capacity that makes them a drag racers favorite? Tough choices.
Every system has some limitations, it just depends on what's important to you and your application. I have no trouble tuning the Accel without the self learning feature, I wouldn't give up the potential driveability for anything.

That's good info Mark. I'd like to tune the new Accel some day. The Gen VII was not a favorite of mine, BECAUSE of those transient fueling tables and overall complexity of the overlapping of tables. That TAU vs table was not understood by any of the Accel tech guys or the EMIC's.

Also not a fan of having the pro key and the cost to buy the key. My buddy's car was a procharged 406 and I don't remember what, but there was something in there we had to tweak to fix an issue. Wasted a bunch of time tuning before we were told about that area.
It was the hardest system for me to tune that I've encountered. Easy to get up and running, but hard to get perfect. We would shut certain things off trying to isolate something, and then in datalogs you'd see they were still working (think it was the O2 correction, been too long to remember).The one we had on a friends car was finally sold after a year and replaced with Fast, and ran great.
I assume the new stuff is not like this? My friend has completely re-done that car and now has a 500 rwhp LS motor in it, and we have not decided on an engine management system yet for it.
