Thanks, Steve. Todd send me a divide by = 4 divider=20 but it didn't put out strong enough pulses for the RMI to pick=20 up....

New Problem:=20 RMI tach no good. According to my RMI engine monitor I have = about 4300=20 RPM at 24 MAP. At 29 MAP I still only have about 4500 RPM and = at 35=20 MAP I am still at 4500 RPM static. I dont buy it because it = sure=20 sounds different (faster). So I have to install an accessory=20 Tachometer.... Tracy, where was the Engine Monitor when I was = building=20 the pannel? :-) I still have holes in my = mixture map=20 as every now and then I pass through a hole and the mixture goes all = haywire.

Like John mentioned, I used a pulse = divider as=20 well. I couldn't get a reliable reading using the 12 pulse=20 output. I divide by 6 using a CMOS divider, which puts out = pulses=20 equivalent to a 4 cylider engine. Most tachs will take = that. If=20 you want I can look up the part number for the IC I used, but I = think that=20 it was a CD4060.
