Replacement Motronic 60-2 Sensor

[petert 549]

I had few problems with a Motronic sensor on the dyno recently. Rather than replace with OEM, it was suggested to use a hall effect trigger as the output is less suspectible to noise. I drew and machined up an adapter to go in the standard hole. So now I have a 60-2 hall effect trigger.

Neat solution Peter!

I'm using the standard sensor on my xu10j4rs/megasquirt, and have no particular noise? I'm revving up to 7800rpm.

An even better solution is to mill all but four teeth off.........

Did you check Motronic VR sensor with a scoop? The amplitude of the signal is correlated with frequency (=rpm), so there should be something wrong with sensor. (Iirc, the later sensors have a different design and could work beter)

 

Milling off all teeth is not better; proper ECU software predicts the gap with 60 teeth in front of it and can measure the rpm more accurately with more teeth. So your current setup is probably the best...

 

Nice job btw!!

The cam sensor also turned out to be faulty. It had a "flutter" at 7100-7200. Sometimes it would rev through it, other times it became the rev limiter. It would only happen at 100% load, not even at 90%. Thus very difficult to diagnose without a dyno. Swapped it for a spare I had and now it's perfect, revving cleanly to 8000.

And where is the link to youtube??

Sorry, at this stage, only this one before I fixed the problem. I had the closed back on the camera, so sound isn't the best.
