Quick video of my car idling on RusEFI. Ignore the smoke coming out the engine bay lol, I think a weld of mine cracked, because my exhaust is hanging a bit low right now as well.

VSS Stimulation

Would it be possible to use the current self-stimulation that is used for RPM, for VSS?
Would it be a matter of moving some pin assignments in Tunerstudio?

A picture might help with comments. Was the OEM sensor surrounded by metal? If so was it a magnetic type of metal?

Re: 2000 Miata Turbo

Did you manage to keep the same gap on your sensor? It's possible your gap is larger or smaller than the original cap and it's creating a weak signal at low RPM. How rigid is the mount? Could it vibrate and shake around some? Yep crank sensor is gapped good. I use a .88mm feeler gauge to gap the se...

Unless JP11 ends are soldered together on the back, you have no signal from op-amps tp PC5. You need a 0R resistor or a piece of wire to get signal to PC5.

I've determined that something's not right inside the ECU for the circuits on INP11 and tachout. I have CLT hooked to PC5. The ECU seems to oscillate around 84 degrees F, regardless if the sensor is plugged in or not. The sensor has a resistance of around 1444 ohms, which does not correlate to 84F f...
