after reading that article I believe I had a detonation induced pre ignition which is why it was not heard :think:

Great article. Certainly makes sense why most manufacturers tune there cars rich and then makes you think a bit about what we do with tuning and then thank christ for knock sensors.............

have had a good boating season and finally have got around to doing a log from Aldroid with speed enabled from the gps on the phone I can transfer the file back to pc as an xdl file but tuner pro does not have the gps speed or xyz options in the xdf file is this an option that could be added as it would be usefull for gforces at the track ,just easier to read on laptop with bigger screen.
I have settled on a 12 x 13 3blade prop seems a good compromise for what I use it for
Have posted xdl file of last log if anyone interested
