Questions:
1. Did you need to rescale load range and if so, how much by; how much load does your engine see?
2. For your baseline timing map when starting, did you pull timing from base or advance map, and approx how much did you pull for a start?
3. What kind of AFRs are we looking for under boost at low level
4. What do you use for manual boost control; did you need to play with the MAP compensation maps?

1. yes i scaled it up to 2.5, it sees 2.0-2.1.
2. the first thing i did with both timing map was smooth out the base, then scaled both out to 2.5grev and set the advance map to 0 up to i think 0.4grev and ~5deg across the board from there. that was to make it easy to see when the ecu was pulling timing in the logs. i then used the total advance calculator to adjust the base to achieve the timing i wanted at peak torque and max rpm, smoothing it out along the way. from there it was just log, bump, log bump, until you see correction then pull back.
3. afr target under boost is 11.1:1. it actually hovers around 10.9:1-11.2:1.
4. i use a hallman pro mbc. iirc i didn't touch any maps that reference map aside from the scaling of the sensor.
