FAST old gray box software

mike britt · 03-02-2022, 10:52 PM

I don't know if the software I have is incomplete or what but the only tuning I seem to be able to do is acceleration enrichment, I can't find a way to change the pulsewidth or A/F ratio. Anybody have any tunes or software for this thing? It's on a 350 TPI motor.

Go to this link: https://www.fuelairspark.com/software-downloads

Then look for "C-Com WP - For Grey Box FAST ECU"

When I click that link all I get is a bunch of garbage about gaming and advertisements.

Link works for me.

Then scroll down to the early software download.

So I figured out how to use the software I have so I don't need anything but time to play with it. The problem I was having was running too rich at idle and blacking the plugs. I got that fixed.

I just about have this thing straightened out but I can't get the O2 sensor to work. Any body that knows anything about EFI knows without an O2 your tuning blind. I guess I'm going to have to call FAST. That'll kill about an hour or two.
