Need a cheap tach fix
installed a chevy V8, HEI ignition in a 90 Jeep wrangler that originally had a 4 banger.
I hooked up the tack and it works - but it reads twice teh real RPM (seeing 8 coil pulses when it expects 4 per tach revolution).
Anyone know of a cheap fix for this? I found a website selling a black box that allows you to hook any engine to any tach for $80. I was hoping for a backyard fix...
Any ideas?Chris
Only the dead fish go with the flow.
The first model car I built was a 32 Ford roadster by Revell in the mid 50's.
How did you get hooked on cars?
