ZF (Cherry) GS100502 gear-tooth sensor is The replacement for original M52 sensor. It gives rock solid signal.

I´ve tested this with M52 original ecu


And in S50-engine Megasquirted:

Ps. I´ve used GS100502 6 yrs now with many engines and configuration and I trust it like my balls. It´s not even ecu related but this sensor solves sometimes mysterious problems that seems to be more like witchcraft.
so siemens camshaft sensor is VR and crankshaft is hall type ?

No. Crank is hall, but cam is strange one that I don't even know the name. It has two coils and ecu feeds 120khz signal to one. And then measures other one. And from the phase shift that occurs when sensor passes the half moon trigger, it defines cam position.

in future how we can use vag red coils?
Change the 160 ohm resistors to something like 40 ohm and put jumper wire to replace the ignition drivers with jumper wires. Wire from signal input to driver output.

There is now rev1.3 available: https://github.com/pazi88/Speeduino-M5x ... 0documents


- diode for BT module that removes the need to unplug BT module to be able to use USB
- A/C circuit with idle up input to mega (this is still the untested one)
- second external connector that has two more relay output, +5v, GND and serial 3 routed to it.
- minor improvements.

And of course there is no need to populate the components for A/C circuit or the second external connector, if there is no need for those features. But those are there as an option.

Also some have asked if this works in s52 and yes it does.
