Just been up drag racing in this again yesterday- after doing a retune to it.
bhp up from 90 a fair bit, torque up from 166ftlb to 225ftlb. It looks to be on course for another circa 60mpg tank- even with the drag racing and remap..
end result is running 16.8s on track rather than 18s
the mapping was done via the obd2 port and was simple enough to manage when I'd learned the basics.
you can alter the values in a variety of ways..
Freeware software is available online that allows you to alter the values that map the following criteria:
Driver's Wish (this controls the max fueling at given throttle pedal input %)
Boost Target (Maps the requested boost level from the turbo for a given RPM/Fuel volume)
Smoke Limiter (Controls volume of fuel based on air volume and RPM)
Torque Limiter (Sets fuel volume limits based on RPM)
In essence then, I have the ability to raise /lower fueling levels and boost levels on a fairly granular basis.
The output is available via the "View performance" function:
