Dyno figures and videos of my re-mapped 335D

OK, repeat dyno today after the CA Automtive remap.

Gained 47 BHP and 65lb/ft of torque at the wheel, estimated crank values based on a 22% loss in the torque converter, 345 BHP and 512lb/ft The torque gain is most impressive, considering the V10 in the E60 M5 'only' twist at 384lb/ft.

Only gripe, at 3950 RPM on the dyno, the gearbox nanny kicked in to protect the gearbox (as you can see from the graph below engine power was being limited). This is what BMW has programmed into their new 6-speeder to prevent it from overheating and sending the car into limp mode.

However, peak torque has already been achieved at 3000RPM, and 4000 RPM really isn't the type of revolution that can kill and auto gearbox. I'm not sure why, but shall investigate. On the road, the engine pulls cleanly well into 4000RPM even during spirited driving; it's only when I drive the car VERY hard, I can feel the gearbox nanny kick in.

Compared to figures before the remap (rear wheel values)

Here a video of the re-mapped 335D doing 0 -135 MPH at Longcross track

Another video of in gear acceleration 80 -120 MPH

Overall I'm very happy with the gains, especially for the money. My most effective bang for buck mod to date. The gearbox nannying isn't a limiting factor in real world driving and gear changes occur well before 4000RPM. The immense torque and midrange is what that turn the 335D into an ultimate stealth machine.

What I've also learned is not to drive the 335D like an M3, it's actually slower. Make use of the long ratio and upshift before engine efficiency falls; hence, there's absolutely no need to red line the big six.
