Just wondering what others are seeing for your timing advance with a tuner. I have a 5 star tune (SCT) for my 2007 F-150 Harley Davidson. Using an OBD2 wireless scanner and Engine Link app on my iPhone I have seen 23.5* WOT in first gear and 20* in 2nd gear. This is with my 87 octane tune. I'm thinking if adding some timing (slowly) but I'm curious as to what timing numbers others are seeing.

Thanks!

 

That's aboot right.

Remember - these change depending on fuel octane / fule quality, knock sensing activity, type of tune ( perf/tow/ econo), engine load, VCT positioning, IAT, etc, actual throttle position versus commanded ( ETC, y'know), and specific PCM strategy, ... and more ....

So - really can't compare other than in a very broad sense.
