Fast Ez efi

Scoots340 said

Has anyone had any success with Fast's ez efi? I can not get my car to run right with this set up. Acceleration is inconsistent times it will rev up when driving other times it's like its fighting itself. Car has the complete kit, tank, pump, and regulator. When I bought the car this was already on it. Car is a 70 Duster 340.

I'd check the basics. Remember EFI needs high pressure fuel always. Check to make sure you have constant fuel pressure. What's the AFR showing, rich or lean? Are the plug wire boots good and not torn. Lots of easy things to check before assuming it's the controller or the tune that's the problem.
I'd also connect the computer (or handheld) and check to make sure the sensors are ready correct values. Maybe you have a MAP sensor or TPS failing. The TPS is really easy to check with an ohmmeter.
