Some engines (BMW N20) have a trigger wheel that has three teeth; one of them is wide enough that the sensor is always either high or low on the tooth immediately after the 2 missing teeth on the crank regardless of how much VVT is applied. Link ECU supports this option and calls it “Cam Level.” I…

Yes, we can add this feature. Do you have a scope file for EMU PRO from such an engine?

No, I currently have the engine running (ish - I have a stuck injector) on Link G4+ Force GDI. I am looking to switch engines (to a BMW N52) and thus need a new ECU, and am considering ECUMaster esp since it might be able to control either motor. I really like this idea since ECUMaster supports pr…

FYI the sensor wheel physically looks like this: Genuine BMW - 11367598215 - Impulse Sending Wheel for Timing Chain Sprocket - Intake/Exhaust Camshaft (11-36-7-598-215) sorry I know you can’t get exact readings from it but it gives a sense of what I’m talking about (big tooth opposite big gap).

Thank you for the link. Yes, the Cam Level will be faster than the Longer-than-factor. This pattern is very clever, as the engine can start from either an odd or even phase. Currently, we always start from the same phase, so to fully handle the pattern it will require a little more work. And sur…

I was able to start the engine today (BMW N52 transplant); I used falling edge instead of rising edge for no good reason. I used “Shorter than factor” to synchronize the phase though having cam level and being able to start on either phase would be nice. Attached is a captured scope though I don’t…

This decoder was fully implemented in firmware version 225.0 (EMU PRO 225.0-beta). In the Secondary Trigger Pattern dropdown, it appears as Signal Level.
