Yes almost every car I tuned tends to knock somewhere between 1000-2000 area under load. So yes timing is retarded under low RPM and high MAP areas. Fueling is not rich, since enough air is not flowing past the MAF sensor to trigger open loop.
Currently with ~18% throttle opening (25% pedal angle)
1-2 : shifts at 2700 RPM
2-3 : 2400 RPM - Torque converter locks up
3-4 : 2000 RPM - Torque converter stays locked
AVG RPM since time to top gear is 1850 RPM and average MAP is 12.5 PSI or 85% LOD just shy of open loop. Car hits top gear at 40 MPH doing 1500 RPM.
Also the transmission slips much less with a slightly more aggressive drive by wire, so shifts are noticeably quicker.
