VVT angle issues
 

Running SpeedyEFI, Speeduino firmware 2023.05. I've been chasing what I thought was an intermittent misfire, but logs showed my VVT angle was ALL over the place. Changed the cam angle sensor with a fresh OEM unit with the hopes that it would solve my issue.....no change:

My angle and duty cycle seem to jump around, which feels like a misfire, especially under load. Any ideas? Wiring to VVT and CAS are good, just this intermittent nonsense. I did upgrade to a bluetooth module inside the SpeedyEFI case. Could that be an issue? Tune and log attached.

Well....ran through a bunch of diagnostic tests and decided to try removing the bluetooth module to see if that helped. Runs fine now. Any ideas? Could the module be bad or do certian Speeduino firmware packages not play nice with BT modules?

I realize this is an older post, but out of curiosity what trigger wheel are you running?

FWIW I've never had an issue that I traced back to the bluetooth module and I've been running my ECU with bluetooth for over a year now.

Running the stock trigger wheel. Ever since I removed the BT module, she's been running like a top.
