Porsche 993 TRA FRA parameters
Those with a Durametric or PST2 or other Porsche specific monitor tool...
What are the expected values and +/- range for TRA and FRA?
If I understand correctly, TRA is the fuel adaption (adaptation?) at idle and FRA is the fuel adaption under load.
The Durametric that I have tells me 4.0 for TRA / TRA2 and .90 for FRA / FRA2.
Can someone out there share what these parameters should be for a stock 993 C4S engine?
