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"

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.

Any ideas? I still can't get the O2 to read. Wondering if I get a separate O2 can I overlay it on my graph to try to get the fuel right.

So FAST is telling me this thing will never run right without an O2 reading. I thought if you ran it in open loop, which I thought everybody did, it wouldn't matter if it gets an O2 signal or not.

I run a holley dominator ecu in closed loop. It runs consistent and pretty fast.
