Autometer Pro Comp Diesel Tach

Is there any reason why the Autometer ProComp Diesel tach would not work on my gas truck? A diesel tach only reads up to 6K RPM. I think a 8-10K tach in a truck that goes nowhere near that would be stupid.

Any issues?

In theory, something like the procomp diesel tach model 2888, that gets it's signal off the alt, should work for a gas engine as well.

To use the alternator style you'll need an alternator with a tach output.

Otherwise, doesn't the Autometer use a magnetic pick-up from the balancer? Or maybe a photo-optic style, either way it's doable.

Just more trouble, but if it's free... why not?

Dakota digital makes an adapter to convert a gas tachometer to a deisel engine. It picks up (counts) the teeth on the flywheel. Planning on using one on my Cummins when I get it swapped in. Heres a link.............

It's possible that some do, but not the 2888 that I had suggested

Interesting... calibration looks like a bit*h though. A magnetic pick-up or photo cell looks to be fool proof and no calibration needed.

I don't have anything for free...but when I redo my truck I will be wanting to use all Autometer guages. Professional ones like the Pro Comp's if you will. Looking to get that "racing" look. I love the 5" tachs with recall, but I just didnt want one that goes up to 10K. That would then just look foolish...Autometer has other cheaper tachs that go to the 5-6K range for gas vehicle, but they are cheap looking and not quality. Everything has to be top notch!!!

Glad to here that it is likely possible....
