Why is that ? Less power for PWG ?? Did MHD mention that PWG will make less power ?

Yeah, in the long post above, it shows less power for PWG.

pwg has less power because the compressor wheel of the stock turbo is smaller. It's a hardware limit.

[AZ-MCRacer]

Is the Compressor wheel on a PWG Pure Stage 2 = to an EWG Pure Stage 2, or is the EWG also larger on the upgraded turbo?

finally

so now it's possible to hit high boost safe for big single n55 like the n54?
the maps for big single n55 will be same as the n54 ?

im ready for testing

[Marlinman]

and we still have BM3 to think about too, they hopefully will be making an announcement soon.

Can i get more info on what are the options for us JB4 users? Will we be using both?? Flash + jb4??

What about the free maps? More info pleasee, sounds too good!

Similar to what we do for the E series: http://www.n54tech.com/forums/showthread.php?t=29236

EWG PS2 and PWG PS2 N55 are similar. The only difference is the turbo housing meaning the turbine side flange on EWG cars is 4'' compared to the 3'' PWG outlet. But the internal wheel combo is same and power gains are similar as well.

Terry if i flashed an OTS will it not work with the JB4 ? I will be using either map 2 or map 5

Wow this is all great news here! So excited that bms is offering free back end flash to guys who already have jb4, I was always wondering how this new obd dme unlocking would effect/benefit someone who already has jb4.

Anyways, a couple questions would be whether or not the Evolve-R cable from evolve automotive will end up working for this upcoming back end flashing (I have mine from my e46 m3 tune
Also, will the big time burble tuningg be avialable similar to the bm3 option for gunshot burbles with PWG?

Thanks a lot hope to hear more on this soon!

[WaqasRiyami]

Will MHD option's as
1)burble 2) cold start cancel - be in the backend flash ??

Any chance somebody can elaborate on this comment? Are u trying to say that the flash tune for pwg from mhd makes less power than jb4 map 1 or 2 on pwg?

I am here for some understanding of what benefit the back end flashing will provide to me on my pwg n55 running the jb4 already. Will power delivery be smoother and more consistent? Will the back end flash in combination with jb4 make more power than just the jb4?

Terry or anyone can you explain the benefits we can expect on the f30 n55 pwg with jb4 and a back end flash?

Also what are you guys talking about punching firewall grommet? Lol

[Terry @ BMS]

For a stock turbo PWG N55 I don't expect major benefits with the back end flash, but if your car has specific issues we'll have more tools to address those. For larger turbo PWG vehicles they really need a good BEF to be properly tuned.

I have an X3. I don’t have the same extra grommet to run the OBD cable through as the F3x does. So to run the cable, I need to punch or drill a hole through the main harness grommet for it. Pretty sure it only applies to the F25/26.

I just poke a screwdriver through it, takes 3 seconds. And when you pull the OBDII cable back out the rubber snaps back in place so its not like anyone would ever notice or care if they did. You're worrying about nothing with that.

X3 here too PWG, it’s basically a circular cover that can be sealed back up if you wanted to uninstall the jb4 obdII wire. Just don’t lose it.

I don’t have that. I just have the one grommet that the main harness runs through. ☹️

I’ve seen people use the one behind the booster, but for some reason, mine is sealed. The hole is there under the hood, but it’s not there under the dash.

[705]

There’s my punched grommet 😅
Saved the grommet Incase it gets too cold, haven’t needed it yet.
The hole is a bit big for that one obdII cable.

Once released by MHD, I'll provide full tuning support on F series, as I already do for N54-N55 E series, as long as it's stacked with a jb4.
Can't wait to tune thoses babies.

So your tunes will be like backend flashes's ? Not like OTS maps ? I really want to get my car tuned by you
, so if yes you make tunes that work with JB4 , i will be your first customer..

[trebila]

Absolutely.
