microedge rpms

I have my rpm wired to pin 10. Its the red connector which is on the bottom of the two pcm connectors, the top one is blue. When i first plugged in the microedge, the car was idling high because I had the throttle cable too short. Now the cable is fixed. The rpms are also registering perfectly. I got it to do this by changing the rpm pulse to 3. I'm not sure what rpm pulse means. but, I thought that maybe it should have been set to 8 because of my 8 cylinder car. If I was supposed to play with the pulse between 1-8 to get the proper rpms set, then all is well. If the pulse is supposed to be set to 0 or 8 or anything else, Something is screwed. When the rpm pulse is set back to 0, it registers at 3500 at idle.

I believe thats right. I dont remember off hand what mine is set to, but i believe the instructions say to adjust it until the display matches the tach.

I know the LS1's tach signal is the same as a 4-cylinder. I'd try 4, although I don't really know what the correct answer for your MicroEdge would be.

The instructions say to adjust the pulse until it matches the tach, like stated above. Mine is set to 2. Honestly I don't think it matters as long as the MicroEdge matches the tach.
