Cobb maps

[tbenn1]

Looking on the Cobb website, these numerous maps for the n54,

Can any one explain what the difference is?

And which one is best and why?

Car is uk 07 135i full exhaust, intercooler etc,

Many thanks

Cobb provides pretty good documentation. Could you pose a more specific question?

stage 1 ( drive , sport, aggressive) used on stock car
stage 1+ ( drive , sport, aggressive) used on car with intercooler but no downpipes
stage 2 ( drive , sport, aggressive) used on car with downpipe but no intercooler
Stage 2+ ( drive , sport, aggressive) used on FBO car ( intercooler, downpipe and intake)
E85 map used on FBO cars with 30% ethanol
Race map used on FBO cars with race gas or E55-E60 ethanol kit ( stage 2 fuel it needed).

Pick the stage based on your mods and start with sport mode. Do a few logs and then you change to less/more aggressive,

Stock throttle provide stock like power delivery ( 40% gas pedal -> 80% output)
Linear throttle 1:1 ratio ( 40% gas pedal -> 40% output)

The more aggressive your map is, the more you will like the linear throttle.
