Z4 N20 Stage 1
Hey peeps,
Had my Z4 remapped today. Can highly recommend getting it done if you run with a 2.0T. It runs much more smooth now than it did before.

240hp
The dark red is the old curve the brighter is the remap.
Lower green the old and the higher is the new

hk = hp in danish.. Before the remap he did a pull too see how much power it had stock. After the remap he did another pull and compared them on the same sheet. See how wobly the darker red line is in the higher RPMs. Its the wastegate which works much smoother now also.
It went from 190 hp / 300 nm to 240 hp and 360 nm. You could take it to 260 hp 400 nm but i didnt look so much at number i looked at the lines and lambda numbers mostly.
In Copenhagen, Denmark. I will go with you if you come here with your car

I thought torque and bhp always crossed over at 5250rpm?

They should do if the graphs are extrapolated correctlySteveSmith wrote: ↑Tue Dec 05, 2017 2:05 pm I thought torque and bhp always crossed over at 5250rpm?
Mine measured 179bhp on the initial run but the evolve Dyno is known to be conservative.

Guess it depends on what gear you make the run in? This was done in 4th he also made one in 5th to 260 km/h where it showed 243 hp at 5271 rpms.
