I was talking to one of my buddies at Comp about this thread and got this e-mail from him. Since it is Comp's policy that employees don't get involved with internet forums I hope I don't get him in trouble by posting it for all to see. I thought it was good info.

You might want to suggest to Michael that if he is running in Alpha-N, he needs to try his program in open loop. Alpha-N ties the ECU to the TPS and tunes more like a carburetor that way without influence by the O2. Then use the O2 to track the results and make changes to his fuel map. Most of the Super Stockers I know of do not hesitate to go into the 13:1+ range with no damage. The Comp cars are forced into the 12.5-12.8 range because of the compression, but where there is very little………….

Also, there is a FAST option right in the catalog that is Digital Air/Fuel Meter RPM Module (part number 170536) that allows engine RPM to overlay the A/F ratio readings with an existing or new single or dual A/F meter during playback. "End Quote"

I hope this can help.....
