Speeduino is now on Github Sponsors (Rather than Patreon): https://github.com/sponsors/noisymime
Any strange behaviour, crashing issues etc, post them here! Problems compiling the firmware should go in the General support section rather than here

Hello ! Im running speeduino on my Bmw m50 turbo (stock vr sensors).
Running it on sequential fine till today, full throttle pull with 1st and 2nd gear till rev limiter, then engine turned off and didnt start.
Doesnt sync on cranking...
On semi sequential all works again so seems like it doesnt get signal from camshaft position sensor.
I check all the wires and they are OK, I also tried with another sensor and the problem still same.
What could cause this ?
I dont have a log from this pull, and there is no any changes in msq from other days while it was working.
Thanks guys !

If you are sure sensor and wiring is good all the way to ECU, the input on the Arduino may have failed.

Replacement will be needed

Try a composite tooth log to see if the MCU can see the cam input

I replaced the Arduino with a new one, but problem is still the same :cry:

Then either your wiring is no good, the sensor is no good or the Speeduino board has a fault.

Easy to check each of those.
