Tachometer? In my head unit?

[PantherP74]

And it works! Anybody wanna tell me how?

I kept playing with the calibration until it read 750-850 rpm for idle (in gear) and now it seems accurate right up to the 5200 rpm shift point.

Everyone thinks it's the neatest thing but nobody can tell me how in the world it could be accurate if it's not hooked into anything that a normal head unit wouldn't be.

Thanks in advance!

Hmmm video please! I'd get a DEH-P7800MP if it gave me an in-dash tach.

maybe it uses that frequency interference signal from the coil somehow, you know the crap that usuallly bleeds through to the speakers and gets reproduced as a whine that changes with rpm

Magic :confused:

Wow, guys, eight responses and only one half-helpful one. :P

I'll see what I can do about video, but I'm not promising anything.

All it does is use the dirt in the power supply to find out the RPMs.

My response was only half helpful?!? How dare you!

Oh, that's it. You've insulted my honor. I demand satisfaction! I challenge you to a duel.

[PantherP74]

I guess it wouldn't help to tell you that yours wasn't even the post I was referring to for being helpful.

Sure, bring on your duel! My place, tomorrow, noon.
