: knock sensor and timings - yet again :)

10th September 2004, 10:30 AM
The saab manual states that its best to run the standard 93T with 95RON fuel and the HOT/aero versions with 98RON.

Is this just the ecu default ?
What i mean is, can the sensors still adapt to any RON fuel and 'override' the ecu defaults over time?
eg can the 93T adapt to 98RON and take advantage of it? or is it designed to run optimally with 95RON and only an ecu upgrade can change this?

sorry if its a stupid question.

cheers :)
