it's not a matter of having a smaller or bigger turbo, it's about giving the best launch at the best traction possible in order to give the best acceleration. just like i said earlier, you'll need to give it a few runs before finding out which RPM to use to get the best launching point for your car.
as for if it resets or not when the car is switched off: no it doesn't.
WAR chip provides the ability of loading 4 tunes to your chip and selecting which one to use through the selector knob provided with the package.
in my case i have loaded 4 tunes into the chip, and i will be talking about 2 to help you better understand this case.
the 2 tunes are: 1. performance tune, 2. performance tune with launch control.
the performance tune is the regular tune provided by Miller.
the other one with the launch control is simply the same as above, but with launch control activated and set at 3500 RPM.
whenever i select the one with launch control. the ECU limits the RPM to a max of 3500 RPM whenever it detects that the vehicle speed is zero (only available in 413 and 506 ECUs). once the car is moving, that limit is ignored and the regular rev limited is effective.
so whenever the car is stopped, the rev limit will be the launch control value, and whenever the car is moving then the other/regular rev limit is enabled.
if i want to stop using the launch control feature, i can either deactivate it using the software provided, or very simply switch to another loaded tune.
i hope i didn't make it sound complicated or anything, and please feel free to ask
