Had a go in a remapped 330d..

[shotta287]

... and i'm blown away! Drove a work colleague's N57 330d ~320hp/640Nm and it's very addictive. The surging torque makes it an extremely fun daily driver. Not a fan of diesels in general but this is something else. From a roll, I don't think much out there on the roads could keep up with it. Wonder if long term all that torque will require the auto tranny to be repaired. Must be a few owners on here..

Did you disappear up the road in a cloud of black smoke ?

I had a remapped m57 running considerably less power than that and it still went very well. Mine was a manual and the gearbox just didn't seem very well suited to the engine, an auto is much better imo. Apparently the autobox can handle huge amounts of torque, hence the 35d's only being available in auto.

472 lb of torque think the cut of point for that auto gearbox is 515

I had a manual non-remapped M57 and really rated it! Always enjoyed the sensation of consistent, strong acceleration when going flat out in gear: not the route to quickest acceleration, but it still felt good in 3rd or 4th, and the engine really sounded at its best at mid revs when under load.

I can't even imagine what it would be like to sit in a manual 320hp 330d accelerating hard in 4th gear from 30mph until the rev limiter. I'm sure an auto version would win this race, but it probably wouldn't feel quite so much like taking off in the space shuttle...

(Recently I've changed to a N53 330i - time will tell but so far, compared to my M57, I think the manual might suit the diesel better. The petrol engine will trundle fine at 1500rpm, but it's a bit weedy there, and it doesn't get properly going until 4000+rpm. It really needs a gearbox that can rapidly drop 2 ratios on demand - i.e., not the BMW manual... at least, not with me operating it. Meanwhile, the diesel will pull smartly even from low revs, and I always found this more satisfying than trying to keep it at high revs as the auto gearbox would. Even if doing this costs a bit of acceleration time.)

Try adding a bms clutch stop, weighted gearknob and a clutch delay valve delete and I'm sure the shifting will be better. I've only done the clutch stop so far myself and it did help.

Wait until you try a 335d!

That N57 is some engine I must say..

I’ve got a remapped F31 330d RWD. It’s running around 330bhp and 500 lb/ft. Paired with the ZF 8 Speed auto, which is the only option for this generation of 3 series, it’s mightily effective! It’s an M Sport but I’ve refrained from the usual M Performance adornments and tacky carbon fibre trinkets and kept it looking standard, so it’s a real sleeper. Some of the looks on the faces of 335d drivers are quality!

That puff of black smoke is just a little more of your soul burning away!
