FYI, this is the way I figure out what load columns the ECU is falling into in ECUflash. I basically log the car and look at the timing, as long as the car is not pulling timing from knock and such, logging the timing should give you a good idea on what path the ECU is taking. Generally I take a couple logs and make sure the timing is constant from pull to pull.
Log:
22.5psi peak, 91 octane.
RPM -- MAS Hz -- Timing -- Wideband AFR
2513 -- 384 -- 12 -- 13.1
3024 -- 636 -- 6 -- 11.9
3501 -- 992 -- 5 -- 11.4
4035 -- 1121 -- 6 -- 11.3
4513 -- 1266 -- 7 -- 11.1
5043 -- 1393 -- 9 -- 11.2
5522 -- 1492 -- 10 -- 11.2
6002 -- 1595 -- 12 -- 11
6515 -- 1694 -- 13 -- 11
7002 -- 1731 -- 17 -- 11.1
7528 -- 1796 -- 19 -- 11
Here is the path my ECU is taking through the load columns according to the logs :
