In for exhaust work, stage 1 ECU + TCU on the dyno
This was already running a tune and we have ran it on the dyno to check the power before, with it making more than standard power.
Running the vehicle on the previous tune first, i’m suprised it didn’t make more power at 1.45bar -> 1.6bar. This just shows that sometimes boost pressure alone doesn’t make figures, we ran this one more aggressive on boost whilst still preventing it from having the usual compressor surge these can have at low rpm and high boost pressure. Still requesting lower boost pressure as it spools and holding 1.6bar tailing off to 1.55bar top end. With some timing adjustments it made some nice gains 🫡
Completely different power and torque curves between the tunes as you can see with more volume over the whole rev range making it such a quicker car with power still rising till redline!!
Setup with 1-1 pedal demand, boost cap in 1st and 2nd to aid traction so once it gets into third gear and has full boost it gets off 👌🏻
Beautiful example of a cupra that is tastefully modified 💪🏻
We sure do love tuning the EA888 platform whether that’s a stage 1 or a stage 3
TCU also mapped with shift speeds, clamping pressures, oil pressure management making the car a more pleasurable drive whether you’re driving normally or giving it beans 👊🏼
