powerfc and tachometer

[MoogLe]

hey guys.

there's a local guy that i'm looking to buy a powerfc from and he's telling me that it has a small problem which is that when it's hooked up, the tachometer in your gauge cluster stops working.

But he says that the hand controller displays the rpm's just fine.

So does anyone have a clue as to what might cause that and how to fix it?

he said that someone told him once that there's a small addon he can buy that fixes it easily.

help me out here!

weird, my rpms still work in my tach with my pfc installed. maybe its his wiring. see if u can test it in your car before u buy it?

yea, i will be doing that,

but he said it's done the same thing in 2 diff cars so it's a problem with the unit itself

also i would say send it in to apexi to have em fix it if it does the same in your car, cause my tach still works with my power fc hooked up. it might be burnt up in the circuit board in the pfc.

yea, i was looking at apexi's site but they didnt have an email, only a phone number.

i might try calling them up tommorow and see what they say

Tach output is toast, I did that to a stock ECU on accedent. Oops. Likely the damage is visible on the board.
