PROM questions - ZR-1 Net Registry Forums

I wonder if anyone can give me some assistance regarding my PROM?

Recently I brought home my first ZR-1 (1991 #1135). The car is great and I am really enjoying it. The previous owner installed a Doug Rippie chip in the ECM. All that I have is the original invoice from when he purchased it that states that it is a "Level 1". I am curious about the specs of the chip. The cooling fans seem to run almost all of the time and I have read that that may not be the best thing. Plus I am curious about the other parameters such as the timing and fuel curves. The engine runs fine but the idle seems kind of high and unsteady as I come to a stop.

A couple of weeks ago I emailed Doug Rippie, Inc. but have received no response. The address I used was the one on their website to the Marketing Dept. so that may not have been the best one to use. Does anyone have a better place that I can make inquiries regarding this chip?

Thanks in advance for the help.
