I recently purchased a obd dongle in order to read the CVT fluid temperature on my 2011 Subaru Outback. This dongle has also allowed me to look observe other things like timing, knock correction etc. I run on lpg most of the time, but recently ran out of it and ran on petrol for a while. I noticed the engine was " pinging" slightly at about 1200rpm, especially at low speed on an incline. It does not do this on lpg. Is this caused by the petrol ecu adapting to the higher octane lpg, then struggling with 95 octane petrol.? I have observed the ECU trying and failing to advance the ignition advance multiplier ( i think its called) while on petrol to 1.0 and it didn't do it in a couple of days and about 100 miles of driving. When i switched to lpg, it got to 1.0 ( where it apparently should be?) within 10 minutes! Any input appreciated!
