Hi mates
The tacho in my 72 Chally reads roughly half engine speed, it's the same regardless of engine speed, cruising at 70mph it only reads around 1500 rpms!
I thought I read some where it's fairly easy to calibrate from in the car but I can't find a link or anything to show it.
The car has a Mopar electronic ign with an FBO box and the Rallye dash is from another car, the wiring loom is all Painless.
Any ideas?
