Today I encountered probs w/ my redtop and i know it's my fault. I have an SAFC2 and I wanted to raise the idle just a tad so I started messing w/ it a bit. I have limited exprience w/ this controller so I'm pretty sure I changed something by accident and now my car has problems. i filled out the qustionaire below to help you understand whats happening.

1. What setup are you running?

4. Does the car start up and idle without any problems?

no problems at all, only when i hit the gas it sputters

5. With out driving the car how high can you bring the rpms up to?

2500-3000 rpms

6. Can you hold the rpms at constant value? yes

7. Is the car building boost when revving?yes

8. Does the problem occur on a cold, warm or hot engine….all the above?haven't tried the cold yet

9. Once it stalls does it starts right back up

it doesn't stall but if i shut off the car it starts right back up

10. Can you hear the fuel pump running when the car stalls?i have to check

You can always reset the unit by going to the etc. menu and going to "initialize" and then selecting that. You are going to have to go through the initial setup again but you can always call us at Apex Integration at 714.685.5700 to be walked through that. Additionally you never want to mess with the unit and always take it to a shop with a dyno if you really dont know what to do. You can cause serious damage, not like you werent aware of that already. Also dont forget, you will lose all set values, however it sounds like you dont know what those values are...call monday.
