Are they working on it for manuals or is this going to be an automatic only tune?

I would think 100% yes it will be available for manuals. There is no way terry would do it for auto only. For those wondering even stock the stage 2 will make considerably more power than stage 1. I personally cannot wait to try it out. Even stage 1 is impressive.

Interesting thread on f30 8spd tranny ratings.

http://www.f30driver.com/forum/showthread.php?t=948666

Seems like the the standard rating is 369ft/lb. I imagine a 10% fudge factor, so 400 might be within the limits.

Thoughts?

There is no simple equation. Only time will tell but they should be fine under 450.

Comparing the numbers, it doesnt look like a 'considerable' power upgrade from stage 1. I guess it's all about how you define considerable I suppose.

From what I could tell comparing the the posted dyno with the stage 1 dyno (both with DPs) it looked like virtually the same peak hp and around 10 more tq. But one would expect not much of a peak power bump from just a tune anyway (can only turn the boost up so far reliably).

Now where the real benefit may be is where the power is made across the RPMs and he mentioned lag reduction. Both would be great reasons for the upgrade, but I wouldn't expect anything like 30hp/50tq above stage 1 with only stage 2 as the mod.

But I'm no expert and will probably be getting it when it's released

20 peak rwhp and 50 lb ft is a nice bump but E85 takes it to 35 rwhp and meth will most likely add 10 or so. Which will be around 45 to 50 rwhp over stage 1. Might be able to juice a little more out with tinkering and maybe an intake. But your right about the curve that is what will make this feel like a beast.

We need more Downpipe options.

Can't wait to see the first 11 second F30.

I think there is only 2 or maybe 3 N55's in the 11s period. Simply horrible.

The F30 Stage2 is similar to the N54 and E90 N55 JB4 with the exception of functional dash control. So, no in dash gauges. But you can cycle through maps and disable the tune all together using the steering wheel controls.

Overall gains were on par with E90 N55s. Huge gains under the curve more so than peak gains. Typically speaking map 1 would be used for factory downpipe, map 2 for aftermarket downpipe, and for those lucky enough to have E85 access that can be used with or without a downpipe. Alternatively racing fuel can be used instead of E85.

Up next some additional refinements and then will start looking around for alpha testers. Initially the upgrade kit will be available only to automatic F30s who have the pneumatic boost solenoid. You'll add a few wires to the harness and replace the control box with the new JB4 module.



mike, will there be an economy/no boost map?

Yeah the DCT a lot of N55's came with was not good for drag racing. I am hoping the the ZF 8 speed will get us there.

~370whp @ ~15% drivetrain loss = ~435hp...

When you consider all the attributes of the BMW 335i, it is difficult to find a better value-to-dollar car within the segment...

Cost, on par with competitors like S4, G37, C350, IS350, S60, etc
Luxury/Comfort/Amenities/Technology on par with competitors
Looks, very subjective but on par with competitors
Performance with 500$ Tune and 500$ DP = 435hp

Thoughts?
That's 369ft/lb at the crank. This tunes with a downpipe is making about 450 ft/lb at the wheels on a stock car which is closer to 520 ft/lb or so at the crank. I don't see how this is going to work.

I'm thinking its an assumption that the transmission rating is based on crank torque since that's where it connects. Stage 2 Map 1 + DP = 419lbs to the wheels which could be considered roughly 493lbs at the crank (15%drivetrain loss), this could be an issue. Not to mention map 2 is 449lbs to the wheels (roughly 528lbs at crank), yikes!

And all this before E85/Race Gas, Meth, NOS....

yeah, I guess this is why you let others try it out...it would take awhile for it to have an impact really (something like 4-5 years of daily driving and flooring it, I would imagine).

Another reason I'm watching this one by the sidelines, letting the engineers at M Performance and Dinan sort out things too...

I don't know about the numbers being crank or wheel because it does not say, but these ZF transmissions tend to be over built. I only keep a car for 3 years so I am jumping in after public release. E85 it makes the same peek torque and meth won't change that number much. Nitrous is not a good idea.
