Hows it going guys,

I have a UA4C with a harness adapter i made going to my 1997 miata turbo build. Finally got the car back together and it started great on the stock ecu but i am not receiving any rpm data on the speeduino when i plug it in and try to start. I have confirmed that the sensor signal is reading 5v key on engine off, and that the sensor has some voltage vairance while cranking. Any help would be greatly appreciated

Log and tune please.

The ecu isnt recognizing any rpm so the log doesn't do much good. The tune is the base 1996-97 set for the UA4C.

Fix your wiring then.
