There are no hardware differences with MPPSK that would allow the car to make more power. So no.

BM3 stage 1 93 vs JB+ (on M240i base map)

Had my 240i on the dyno today. Plot 1 (blue) is JB+ with settings at 3 o clock (not maxed). Plot 2 (green) is BM3 93 Stage 1. This is the same car, I previously had JB+ on it and now have BM3 flash.

Conclusion: JB+ has significantly stronger mid range. BM3 needs to be above 5500rpm where it definitely takes the upper hand. Car is stock otherwise, stock DP.

Just a point to note, JB+ on max settings records between 405-410hp on this dyno.

As it happens, last weekend I ran the 1/4 mile against a JB+ (max setting, 407hp dyno) M140i. My car was 2/10ths faster with a 12.2. @ 114. One run we both did a (less than ideal launch on my part) 12.5 , and our cars were almost identical the whole way down the strip. Very close. I feel this verifies what I'm seeing on the dyno plot.

Which do I prefer?
On balance I have to say the BM3 is the better solution. The softer / more progressive mid range makes it easier to drive drive, I guess. Although not really a good point, less power is never more
Throttle progression is smoother on BM3, and this must not be underestimated. Thirdly, BM3 seems to pull cleanly all the time, every gear. JB+ can have the occasional hiccup.
Oh and AFR is richer on BM3. Some people will be pleased with that.

This analysis is illuminating, thought provoking and much appreciated.

It's ironic, for the most part, that 90% of normal people who use their cars as daily drivers will rarely break 5000rpm's cruising around town and would most likely prefer something more akin to a JB+. I'm sure the forum enthusiast, dyno worshippers, and internet racers will scoff that they aren't getting absolute power boasting peak-power and that there is no way something under 200 bucks will suffice for them...."Gotta pay 600+ so I know it's good."

But I digress...I suppose if you're happy with it then that's all that matters in the end.

For me, it's not even about getting as much out of the engine. It's about protecting the drivetrain and having a lot smoother power delivery. Better 400 dollar difference than a new turbo or other drivetrain work in the thousands

[Relique]

These are pretty good numbers for a stock stage1. Does that dyno run a little high?

[MTWO]

JB+ is weak top end just completely dies

He's from the UK so that would be HP, not WHP.

[ivanj308]

Since BM3 does not offer a transmission reprogramming option I am wondering if they are limiting the midrange torque of their tunes due to the torque limits of the 8AT.

if that is the case I wonder if they would create an OTS specifically for the 6MT without the torque limits

Did you guys see this? Holy f&$@!

Thanks for posting the times, is your 240i AWD?

What's the curb weight?

[Mkswoosh]

Persuade me to downpipe and stage 2 map for the 340i. I'm simply happy where my car is at. But then again no body has tested me (on a safe enclosed cicuit) of course

Standard weight car, rear wheel drive. Standard MPSS tyres. ZF8.

So it did a 1/4 in 11.25 at 200kmh which is 124mph. Damn that thing is moving fast. Wonder how consistent these results will be on other cars using the STG 2 OTS E30 map + dp + intake.

Very fast
Who knows, but probably not that consistent. That Dragy user has very fast times if you go and look at his profile page and not just with this car, but every BMW he drives and does a Dragy run with including bone stock BMW's

[B58togo]

Yeah, that 124 mph trap is nuts. I've gotten a couple 118 mph runs on the Dragy, so it's tough to see how E30 could add 6 mph to that. What would E30 be good for over straight 93, maybe 20-25 whp?

Very consistent that is why they're heavily testing it and showing everyone what it's capable of doing with a good driver and the solid OTS map that it is!

haha look it is, you must be jealous your slow jb4 pos trick or trick cannot keep up?
Dragy is the way to shut up all you downhill racers since there's no 1/4 mile track overseas.

E30 has so much more fuel in it than 93 that of course it makes sense.
I did 0-60 in 4.19s and 1/4 mile in 12.4@110 in my X4 M40i (N55) and with E30 it did 0-60 3.88 and 1/4 mile in 12.1@114 (mind you this is a 4495lbs beast I had previously)

Anyways the B58 is a monster and it shows what a good solid OTS especially my favorite 'E30' will crush hearts! Great job on the hard work, time, sweat, dedication proTUNING Freaks and Halim@HCP are always putting out for every engine under BM3 support !

- A lot of us hit 7k every day, me included
- A lot of us enjoy the ability to log, switch maps, get tune updates, etc.
- Pretty much everyone sells their license/buys used so really it's $300
- A flash tune will always be safer than a boost controller, especially when it's spiking boost in the midrange vs. smooth boost onset with a flash tune. That's how you burn clutches and blow drivetrains (not that there's a huge risk with JB+, but still)

It's been posted a couple times that they modify the torque limits in the tune so it can circumvent the intervention in the 8AT. So they aren't limited by fooling the trans into thinking it's making less torque.

Same. I'm actually more interested in a Stage 1 E85 tune than a Stage 2 93 tune. I don't feel like spending another $500 to go from stage 1 to stage 2 will be as impressive as the $550 I spent to get to stage 1 with no other mods.
