Reason for fans running while programming PCM??
Is there a reason why the fans run while programming the PCM. Those fans drain a lot of power from the battery, and I'm wondering if it isn't ok to unplug the fans while programming. I get worried everytime I program it now that the fans are going to kill my battery again.

With LT1 Edit they only "flash" on for a second and then turn off. I have another problem, the electric waterpump! I just disconnect it before I start so it's no big deal.

Ok, I wasn't sure if it was going to mess up the programming if I disconnected them. The way my PCM has been acting with me, if I were to do that it would screw it up and I'd have to have the chips reburned AGAIN.

While having my 94 BBB convertible programed in the spring of 2000, the very disaster that you have envisioned did happen. My fans ran contiually, and when the modified program was being uploaded, the battery power died, and so did the program. I had to send the computer away to get it blanked and then get the program reloaded.
