When I crank my engine I see that there is no readout on the tuner studio engine speed tachometer.
Here is my build;
4age (4 cylinder) 16v + 20v ITB conversion
hall effect sensor + 36-1 trigger wheel
COP conversion
narrowband o2 sensor - oem toyota/bosch sensor
speeduino v0.4c with mpmx4250 sensor
My other sensors have all been calibrated so with this I am lost. I used an oscilloscope to see if I am even getting a square wave signal and I am as shown below. In addition I've added some other pictures that may be relevant as well as the msq file.
Any help would be appreciated. Thank you for your time.
