iijj,
The reset won't do anything, do it if you like.
Tuning wise; I guess I put the 'graph mode' on and use rev's Vs knock. I take a refference on the log and look at the peak values on the other screen. Take away fuel, take away timing, add fuel add timing.
If the car is pretty stock the afr can be pegged back in the top end on high throttle and on low throttle in the low/mid range I've added a bit of fuel to improve throttle response.
