Typically a 20 minute mixed driving with two 3rd gear pulls from 2k rpm to redline, plus two minutes on tickover. You do this with flashpro plugged in and datalogging. Upload datalog to computer and give it a name, I did rev 1, rev 2 etc. Email to tuner, they send you an updated map, then you load it and datalog again.
Yeah this is pretty much spot on
20 minute data log trying to incorporate every type of driving. 2x 3rd gear pulls to the redline, Chris then changes and modifies this basemap based on your datalog and sends you revised map with all of the parameters changed.
Chris does do a good job there's no doubt about that - he did loads of testing on his own motor to get it right, and he does turbo kits too.
So then you get your second revised map back, upload and repeat. Continue this until you're on revision 5 and by then everything should be about as good as it can get, the way Chris explained it to me was that he tunes a car 90% of what he could do on a dyno, and the only thing that could be improved with a dyno is the peak WOT (wide open throttle) figures. IMO if Chris can tune the car to that level over the internet...for £150 I'm happy until I go seriously modded then I would go to tdi.
With a gruppe M and a catback, what's that extra 10% gonna be? And extra 2-3bhp absolute maximum haha?
He's also putting launch control and flat shifting on for me
