Default 125 B48 - map 1&2 review - 12-25-2018, 04:15 AM

i just setup JB4 on my bmw 125 b48 8AT (aus model).

attached logs, need some feedback regarding map 1 & 2. thanks in advance.

few observations:
- map 0 vs 1 vs 2 do not 'feel' significant power gain difference.
- while on map 2, full throttle, the upshift feels lags about half a sec before full power picks up.

Both map 1 and 2 look really good. Try and get a few more on map 2.

Thanks Payam for review.

please find attached more map 2.

after a few days, this is what we found:
- we can 'feel' map 2 seems to produce more acceleration. I will put this on dyno in the next 3 weeks.
- zero to full throttle (in manual mode) at any gear above 3k rpm produces 'back and forth' power response. E.g. the power comes in really strong for a short burst, followed by looses power abit, then, full power kicks in again.

is there ways to tune out the 'back and forth' power response issue?
