BLKMGK Posted September 14, 2001 Share Posted September 14, 2001 Have you got th eJTR book? It describes ho to do this for the various years. Hint - the 240 tach must have it's guts changed out for a later model and some twiddling of a screw in back done. Quote Link to comment Share on other sites More sharing options...
dmanzo57 Posted September 14, 2001 Share Posted September 14, 2001 I've got a MSD6AL ignition in my V8 powered '72 240Z. I had to install a MSD Tach Adapter, part number 8910, in order to get the stock tach to work. There is a adjustment screw in the back of the tach that can be used to calibrate the tach for the V8. JTR says to remove that tach from the dash for adjustment, but it can be done by reaching up from under the dash. I used the rev limiter to calibrate the tach by installing a 3K RPM module and then adjusting the tach until it read 3K when up against the limiter.
