Garrett Turbo Speed Sensor

Scott- thanks for the info, especially regarding the gaps for installing the Jacquet unit. This is working pretty well on the ADL for us with sampling up to 1k hz.

scott did mine on a FP 3794, Works well after we got the calibrations correct.

If you are having issues with larger comp wheels with thicker blades, INCREASE the sensor gap. It may work best at larger than specified gaps.

FYI they usually don't start picking up consistently until ~3000 RPM, so if you lose speed at engine idle but its OK everywhere else, don't worry.

Bumping the thread.

what would the settings be for and garret g30 turbo with 9 blades for M1 ?

Did you look at the help for "Turbocharger Bank 1 Speed"? It's pretty clear about how to set this up.

Here are some good guesses to start:
Pitch Threshold = 75%
Timeout = 50 ms
Blades = 9
Multipliwer = 8
Sensor Sample Teeth = 0
Pullup Control = On
Active Edge = Falling Edge
Threshold = 2V
Hystersis = 0.5v
