Timing adjustment
My car is pinging under load. Is there a way to back off on the timing (timing adj) I checked the marks at idle and not really sure how to read. I think there was 7 lines and mine was between 3 & 4 starting from the left.

TDC is the first mark on the pulley I believe its orange, each mark after that represents 5*. So after the first mark three marks after that (4 total) would be 15*BTDC. You won't have to unplug anything but the ECU does have to be put in diagnostic mode III however. What you do is have the engine running at normal operating temp, turn the diagnostic selector screw fully clockwise and wait for both red/green LED's to flash 3 times, after that turn the screw fully counter-clockwise. Next race the engine 2-3 times under no load (rev it over 3k rpm 3 times) and this will lock in base ignition timing so you can adjust it.
