Thoughts on the FAST Ez-EFI system??

My last car had the original Fast "classic" ECU, which was actually sold by Speed Pro at the time, and my current car is an older Accel Gen 7 that’s upgraded to the 5.5 firmware (sounds like you are familiar with the system). Both systems have widebands and you can get the car driving really well in no time. Maybe I'm a perfectionist, but I've found you can get 95% of the way there in the first hour or so [with the wideband system] where there is no discernable driveability issues ... That last 5% of tweaking takes quite a bit of time, at least for me.

First aftermarket ECU I retrofitted was a Haltech F3 into an early 3rd gen Camaro, back when it was far more popular to take off FI for a carb than vice versa!

I agree completely.... after the dyno -- it takes lots of seat time! Cold start... is always an issue... getting it to fire on the first revolution (just like a brand new car)... and on and on.

I think that is why I've fallen in love with the FAST EZ EFI... it just works... and seems to get better with each drive... and all I've had to do is DRIVE... it's like gettin' laid by the cheer squad! So easy... and FUN!
