MicroSquirt RPM Readings

Post by marclave »

Hello,

We are currently running the following:
MicroSquirt:http://www.diyautotune.com/catalog/micr ... p-519.html
Tunerstudio MS v2.6.14
Firmware: MS2/Extra release 3.3.3

We are not getting any RPM readings in TunerStudio, I hooked up an oscilloscope and we are getting the right signals from VRIN(18 teeth, 1 missing) can be seen (I can upload an image if needed...).

I tried adding a 10K resistor but that did not help get any readings, I have been looking through previous forum posts but cannot find anything...

Any ideas or thoughts? I can add more info if needed.

Thanks ahead! :)

Have you tried taking a tooth log? (This is covered in the Megasquirt2 Setting Up manual)
