93 Miata DIYPNP No Tach
Hello miata gods,
Not sure if CA 93 cars have anything else special other than stock sequential injection but I can't get the stock tach inside my cluster to function. DIYPNP 1.5 Board Starts up just fine as you can see TS is displaying rpms perfectly fine. I have OP- jumped to 4E and have the OPTO+ with a 470 omh pulled up on the 12v side. Tachout is turned off on TS. Can anyone help? |
jump ig- with b+ using a 1K resistor.
/thread. |
went straight to the diagnostics port and jumped the two with the 1k resistor.
still no movement. |
What sort of ignition are you using on the car?
|
Thanks for chiming in Matt, stock miata coils.
|
If you're using the stock Miata ignition module as well, the tach is driven off the module. This is usually a sign the module is on its way out.
