| There is a 944 FQS Table in the "924/944/968 Frequently Asked Questions" document. Do not use this table! It is for a 911 FQS, not a 944 FQS. |
Early BOSCH Motronic DMEs are equipped with an 8-position Fuel Quality Switch. The switch allows the DME to adapt both fuel mixture and ignition timing for the quality of gasoline available. The Fuel Quality Switch allows the user to correct fuel related engine problems.
