F30 335d remap

NISFAN · 10-28-2020, 05:10 PM

780 lb.ft is 371hp at 2500rpm. Seems a strange mapping strategy to achieve peak power at such low revs.

DynoDynamics are very odd as they also dont calculate coastdown losses (not that they are accurate either) so ultimately guess at flywheel figures.

It showed 313hp. Think book figure is 309hp

/edit - and I've just been thinking that if HP is achieved by a multiple of torque and rpm. Something bloody strange is happening to 'only' get 370hp out of an engine with 780 lbft of it!

I missed the other post, apologies.

780 lbft. Awesome.

My sincere apologies. I've reread this post as I got a notification message.
I have incorrectly stated mine had 780. It didn't.
Can't even blame hitting the adjacent number button, as it's two away. No excuses, I got it wrong plain & simple.
Mine was in fact running 580 lb/ft.

The car was fantastically driveable. 1/4 mile runs at Santa Pod were 12.2s IIRC. It was a long time ago, lol.
With a power hike like this, definitely go for the Alpina Transmission flash. It's night/day better.

Alpina transmission flash???? Wwwhhhhaatttt!!?? Pls tell me more, how, who, what.

I have an f36 440i so b58 / ZF 8 speed, I'd love to make mine more "Alpinaesque"

Contact Zed Coding, see if it's an option for you. I don't want to post his number here, just use Google...
It can be done remotely.
