COBB Tuning: Boost vs Load in ATR

$
0
0
Hi All, so i have been learning the ATR beast to try to dial in the boost for street & road courses.

Problem Statement:
the OTS high boost and fast taper was a bit disappointing to say the least, especially for a 30 minute road course session. High IAT, uneven torque, etc.

methodology:
sooooo, i started logging Stage 2+ aggressive and E30 maps.

plotted boost vs load (Actual), plotted a linear equation, long and behold, a good correlation. and then used this data to get a nice little table to dial in boost.

i used road course logs (1.5 hours of so) of data to plot this, have over 10k points.

looks good so far.

results are attached in the graph.

conclusion:
i understand ever car is different but here a quick starter so you can adjust your custom map boost using load values.

enjoy.
