i wish i could have done that to my 240D, but i have a 1980 without a EGR. i guess the only way i can have a tach on a manual 240D would have to be an engine change?

Funola-

Thanks for the writeup. That looks like a worthwhile mod. Even I should be able to do something like that.

Looks great, and very stock. Did it require any calibration? It seems to read high if that shot is at idle...

That looks great, it always seemed like something was missing on the
right side. but then Iam use to a tach.
There are always great minds at work on this site.

Now you need a 160 MPH Spedo.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

Thanks! No calibration necessary. I had my foot on the accelerator when the pic was taken.

Engine change just to get a tach? No!

You could go to a pic-n-pull and get the mag pickup, EGR controller and harness from an EGR equipped 240D and install it on yours. You have to verify that you have a "tooth" on your harmonic balancer for the mag pickup to sense. If it does not have one, you can always make one by epoxying a "tooth" on the harmonic balancer by using a small allen head screw.

Nope -- you could attach an RPM sensor to the crank pulley or one of the injector lines (piezo sensor - actually measures the expansion of the pipe when the injector pump "fires" - very cool!)
