Very odd RPM reference issue
Recently my microtech LT-10s started to go all buggy one day and the car started to idle very rough and also begun sputtering.
It is bassically a stock T2 RHD FC with only a cat delete.
When I start the car, the rpm reading on the dash is 9500! Using a tachometer, the cars shows to be trying to idle at 1200-1300.
I thought it might have been a CAS failure so I replaced the CAS but no change.
While plugged in to the ecu, I spun the CAS removed from the engine by hand and the rpm is fluctuating ALOT like spinning slowly it is reading 2000 rpm.
Is this an interference issue or just a failure in the ecu? I had it sent out to microtech before and they claimed it was ok and reset the map for me.
