I've been battling a P0336 code. RPM Circuit error.
Its kept me from 2 race events.
This is a 2003 2.7L 3 chain engine
I have verified the mechanical timing with the cam timing tool - The cams and crank are properly in sync.
The crank sensor is good. And a second sensor was tried and tested.
The wiring harness from sensor to DME is good
I can see engine RPM on the scan tool.
per Porsche diagnostics.
The DME (ECM) is bad.
Does anyone have a DME for a 2003 manual trans Boxster I could try to test?
Or a good source for the DME to purchase used?
