TAU -this was borrowed from Ford. Just think of it as an imaginary puddle of fuel that gathers in any manifold. The object is to maintain that puddle, throughout acceleration and deceleration. This is normally for light tip in, i.e. on and off the throttle during typical driving conditions. This is temperature driven, that's a good thing and when set up correctly can really enhance drivability, especially on big cammed applications. The larger the numbers and/or the smaller the gap between them the leaner it will be. The opposite is true if you need it to be richer.

On the flipside, when I as loading the software for the new FAST 2.0 I had some questions. I called FAST, they gave me the names of 5 guys here in Fl to speak with.
1 was out of business, 1 moved to Indy, 1 was Ramseys in Tampa, who I bought my Accel system from in '04. I wouldn't let him replace the spark plug in my lawnmower. Same problem you had Jody, no real knowledge of the systems, FAST or Accel.
The other 2 references I called, 1 called me back. By that time I had figured it out for myself.
My point? I agree too few good tuners out there, at least on this stuff.

Actually I'd put the new Holley ahead of the FAST 2.0, I wasn't impressed with the new running tables on that at all.

For the record, if anybody has any questions regarding the tuning of the Accel, fire away, happy to help.

I'd still put it above all else is driving quality any day, in the hands of a competent tuner of course.

Thanks guys.

I definitely appreciate your participation on this board, and if I ever end up in an Accel again I will probably have some questions.

Same goes for Dennis (64deuce), it's great to have pro tuners like you and Mike Norris that participate on the site.

All I know is the vision in my head shows a Hilborn or Kinsler injection stacks as to what will run it, no idea just yet as i am planning this build still.

After seeing the 1964 GTO that was built for Raybestos at SEMA, i got hooked on doing the Hilborn with LSX in a Goat, for anyone who has not seen that car , just look it up, its mean as hell.

Considering the route i plan to go i may look into using a GM harness and OEM styled computer tunable through EFI Live.
