tachometer reading off
 

hello, I freshly got mspnp2 and my tachometer reading on it seems to be off by around 1000 rpm, what can I do to solver this? also it is not picking up my wideband signal or is not holding the calibration for it since if I open up the calibrate afr table in tools it always comes up as blank. My car seems to want to idle, and I feel my biggest issue is these to factors. I'm gonna link a data log where I kept the rpm around 800 except for a couple revs, and my current tune.

To add to this, its my tach imput that's off, car is stock engine wise so I can't think of anything that would mess with the tach imput, and runs fine on stock ecu. the car trys to idle but its trying to at around 100rpm. the wideband signal is going through the stock o2 signal wire, but just reads extremely rich megasquirt wise.

problem has been solved timing was just off, afr seems to have fixed its self

it's a miata, the tach is off -- this wasn't fixed by changing the timing.

imput was off on megasquirt, fixed the timing the .5 it was off and the tach imput read right. the actual tach itself has always been weird, but the car most definitely wasn't running at 2k rpm like it said on tunerstudio.
