You're the man Kern! You always give the B58 community the info that we need.

[@marklinley815]

I usually don’t comment on KZbin, but I have been a subscriber for awhile now. Hands down, best B58 information out there. You actually explain why things are and not just because. This video made my mind up to purchase this flash!!

[@technopro-kz4xv]

Well said Kern, stage 2 is the best option specially if you are not tracking the car or drag racing. I’m on MHD Stage 1 and xHP Stage 2 in my 440i GC and it’s my daily driver but it feels really nice when you press the gas pedal 😊👍🏼pretty happy with the performance that i have with both flashed options.

[@Dazza367]

Great video and very informative. I have the B48 330i stage 2 with BM3 and have been considering XHP for a while but could not really find the answer to my question about if it was worth it for lower horsepower tune like mine (approximately 350HP) but you sure answered that for me. Big thank you.

[@marwansherin]

[@Vince370796]

You forfot something about stage 2 vs stage 3, and this is DSC off. Manual mode is really slower in dsc off in stage 2, there's a delay between shifts and in stage 3 they are instant. That's why I went stage 3. I just turned down throttle blips to minimum in settings because they were pushing the car when braking.

[@aTakoinaMako]

In stage 2, DCT and DSC off mode does not activate fastest shifting in the latest version. Only v1.0 does so.

[@aTakoinaMako]

Stage 2 was my go to, but then they removed fast manual shifting in DSC off mode in the latest version.

[@LuizPauloDT]

I noticed that in one of the track days earlier this year. Had to move to Stage 3

They don't have a trans Tune for our b58 cars. The ones they have on other cars only removes the torque limiter and doesn't have nearly as many features as xHP.

[@yuncheng8742]

Hi Kern, I really love all the videos you put out; they're very informative! I have a question, I have a 540i and it's on stage 3 XHP and stage 2 BM3. When the car shifts in comfort plus, I feel a jerk which I don't want to feel. Is there a way to have OEM settings for comfort plus and then stage 3 XHP on sport + or should I use stage 2 XHP and it should be less aggressive on comfort plus?

[@kern417]

It's probably the slow shifts in comfort +. Try selecting one of the presets in the shiftmap options

[@sevyn8038]

What are we looking at from a normal bootmod stage 2 to adding a stage 2 or 3 tranny tune in terms of 0-60 or 1/4 mile improvements?

[@ScottPC]

I’ve got stage 3 installed and really don’t find it jerky at all. Depends on user I suppose. The new M135i /M235i have the worst and harshest gear tunes I’ve ever experienced from factory. It literally lurches forward when it shifts gears 😂

[@Y.D.43210]

Exactly my point! Stage 3 is absolutely nothing in comparison!! It must be said the M135i has a different gearbox though, not ZF, but fact remains - in Sport (out of factory) it kicks you like an angry stallion!! Stage 3 is a kitten playing in comparison... so I also don't understand what jerkiness people complain about.

[@ScottPC]

@@Y.D.43210 yeah I’ve heard it’s not ZF but it’s hugely more aggressive than even stage 3 XHP 😂 Could class it as stage 5 in comparison 😂

[@GTS18]

Thank you for bringing new about B58 man I really appreciate the work you do, I have one simple question, as far as I understand, bmw x40 engines comes with a different torque converter than the one in 540i, how much can I push with the stock converter before looking to upgrade to an M Performance torque converter or another one in order to make some gains, I really don understand why the 540 G30 comes with a different torque converter than the 440, 340 cars? Thank you.

[@kern417]

I haven't seen anything regarding that. I don't know of any 5 series with slipping torque converters, even with big turbos

[@michaelcollins8774]

Great video👍Slightly off topic but I’ve often wondered if the software update that’s part of the mppsk install at bmw adjusts the gearbox software as it seems to improve shift times in sport+ (could be wrong)

[@willm2624]

Would you say stage 2 will produce the same times as stage 3? Also I’ve heard people claim that the line bump is not active 100% of the time, and that it increases the pressure as it sees that it needs it. Do you know which of those statements is true? Thanks for the content Kevin.

[@itsdakku]

This comment^^^

[@kern417]

with the right settings it's the same. just depends. stage 3 will put you in the fastest shifting modes more often.

[@ian.gomez_]

One question I have always had is, how hard are these tunes on the transmission/ overall health and longevity in general? I had to flash stage 3 after installing my big turbo as stage 2 was limiting the torque pulling from 50’s and would cause a split second loss of power before picking back up.

[@kern417]

Generally it isn't an issue. But some settings allow you to push the limits so you should be aware of what's happening before you go that far

[@ian.gomez_]

@@kern417 Thanks brother! Quality content as always 🙌🏽

[@ebigford34]

xhp stage 3 works better and smoother than stage 2 with my 440i bm3 stage 2 e30 flex tune. regardless, you can change settings with any stage for torque, shift aggression, etc.

[@kern417]

That's really the key. It doesn't hurt to try all the maps and just pick what you prefer. I'm still confident a lot of feedback is placebo but ultimately going with what you like will make the experience more enjoyable.

[@Mr-ni2cc]

I'm thinking of going MHD stage 2 on my daily, should I proceed to purchase xHP? I'm not racing or doing anything like that, just want that power.

[@kern417]

It's great with any tune. It just improved drivability overall. I think stage 2 is the perfect Middle ground.

[@kevekulcsar5732]

Is it normal with stage 3 that the shift on low throttle and low rpm that the shifts from 1 to 2 break my neck? Or is it just part of the aggressive experience thing?

[@marcussilva8440]

Its been 2 years since those b58s came out, shouldnt there be some kind of progress on figuring out a way to crack the dmes?

[@rossclarke10169]

I’ve found recently that the custom Launch control is now working really well. Tested on Stage 2+ RWD 440i with XF8 took half a second off my 0-60 time.

I'll have to give it a shot 👌🏾

[@onekind1554]

so on WOT stage 2 and stage 3 have the same shift speed?

[@kern417]

With everything else equally yes. A lot of it depends on your drive mode and transmission mode, but they have it set up to automatically go to the fastest shift mode when you're wide open throttle.

[@KurumaDesigns]

Doesn’t also xhp reduce lag in manual mode? Like when you hit the paddle or shifter to gear up, there is less of a delay before the transmission shifts. I don’t have experience with xhp myself so I don’t know if this is true.

[@bfidy8]

It does shift faster and harder, especially sport plus and DSC off. I'm currently on xhp stage 2

[@kern417]

They modify the shift mapping so it's more sensitive and downshifts earlier

[@mevans313]

Yes, I have stage 3 and it’s far more responsive.

[@johnmccallmusic]

Bro... I love your channel! So helpful. Okay, I am going to buy XHP but I need to fix my 540i first. Can you help me, please... Ever since I upgraded to the B58TU fuel pump. I can not get my car to make any aggressive pops. I use BootMod3 and running the Stage 2 plus. I have a stock exhaust, VSFR high flow downpipe, charge pipe upgrade, and K&N air filter. With that said... I could make it very loud before the new fuel pump install. Do you have any clue what might be going on? I have tried refreshing back to stock and then back to the tune. I changed the custom burbles to max and it still sounds the same. Help please. Thank you!❤

[@kern417]

Not sure. I would message PTF for help addressing it. A pump doesn't do anything with burbles.

[@kwakufordjour9568]

I am yet to buy xHP just for ignition cut aka upshift farts. Can I go with stage 2 but then add ignition cut?

[@kern417]

sure

[@Echelonperformance]

Those of us with a90s is it worth adding sport plus thru Bimmercode with xhp or stay with ots maps

[@kern417]

I think so. If it's like F30, it just combines all the fastest modes from everything, plus softened traction control to let the wheels slip a bit. It's great for performance and fun.

[@Y.D.43210]

Great video, but one very essential detail you missed out is that the difference in shifts between Stage 2 and Stage 3 is ONLY in Sport+ / Manual, not in Sport or Comfort, which remain the same in both stages!! This is crucial for those of us who drive predominately in Comfort and Sport and use Sport+ / M (or practically S) only when really aiming and expecting maximum performance and maximum aggressiveness!! Also, maybe it is something I've read but forgotten - are you suggesting in Stage 2, shifts are faster in Sport+ compared to Sport? Do you know for sure / can you confidently feel that? IMO they are the same (faster than in Comfort, of course). Apart from that - I tried both Stage 2 and Stage 3 (starting with Stage 2). To me, Stage 3 in Sport+ / Manual is not at all as jerky as some people describe it, the shifts are harder but N O T H I N G compared to e.g. M135i's stock (!) gearbox shifts in Sport, which crack your back on every shift. And since I rarely use Sport+ (and when I do - I don't mind the extra sauce) - I stayed with Stage 3, as in Comfort and Sport it is essentially Stage 2. therefore again - it is crucial to understand that Stage 2 Comfort = Stage 3 Comfort and Stage 2 Sport = Stage 3 Sport!!

[@bsturn]

Yes, I can tell you for Stage2 that shifts are faster in Sport+ than Sport (I believe the app mentions this.) This may depend on your iDrive settings though, for me with S2NH, I can chose whether to have dampening adjusted in Sport or Sport+ only.

[@kern417]

That's exactly what i said at 11:50. Maybe you missed it.

[@Y.D.43210]

@@kern417 My bad - you do mention it there indeed, but I would have put a huge spell on it. That's the key for understanding the difference between Stage 2 and Stage 3 and for choosing a Stage. There is a common misconception that Stage 3 is "harsh" and even "dangerous" irrespective of the mode which absolutely isn't true.

[@Y.D.43210]

@@bsturn Not sure what M Sport Brakes (S2NH) have to do with the transmission but I get your point about manually setting Sport mode. In my case Sport is with its default settings and I am not confident the shifts with Stage 2 Sport+ are any different than in Sport. Happy to be corrected. From memory xHP only say that the drive modes control the shift speeds, but that doesn't necessarily mean that there are 4 shift speed modes - in reverse order the shifts are not any softer in EcoPro than they are in Comfort.

[@kern417]

@@Y.D.43210 This is an overview video. The primary point is to show that one stage isn't designed for more power like engine tuning ots maps. They just enable different features in different settings. It doesn't make sense to harp on just one feature.

[@HargunSV]

Currently stage 1 340i rwd, im going xhp stage 2 before i get a DP. I’ll prob end up doing some suspension work and sway bars before i go stage 2. Also gotta make sure your tire setup can put that power down. So it really depends on your goals and if you’re ready for stage 2. and a stage 2 transmission tune will work fine with a stage 1 ecu tune, you shouldn’t have to worry about matching the stages. Personally I would go with xHP tune next, it’s fairly cheap and no install required. Dp is also pretty affordable and if you already have MHD license then ur good to go whenever you pop it in.

Once you go hybrid on the 340 I’d be interested to see what you change in the settings. While they raise the rpm a tiny bit it still goes into 8th fast at low rpms and kinda bogs you a bit if you have max torque at 3-3500rpm. Tried sportive shift map in the editor but it’s still not rly where I want it

[@alexk4804]

in the options where you chose sportive you can also do custom to change when each gear shifts

[@przemekgodzik56]

Im also curious how hybrid turbo affects to normal daily driving with D mode, is there still enough power to drive 1200-1500rpm ?

[@SpiderGamesHard]

@@alexk4804 yeah but not sure how I should go about doing that. The presets don’t add the same % to each gear and if you do it wrong it can make the car really weird to drive. If you have some settings I’d love to try em! The standard xHP shiftmaps are def made for stock turbo. Adjusting a slider with a % is hard to gauge compared to just setting an rpm Ideally in d mode, rpm would be at like 1800 while cruising but shift down with a little gas to be in the power band more and feel less sluggish. Shifting at 3k with 25-40% throttle and higher at 4-5k above 50% throttle. And hold 6th and 7th gear longer so you’re not in 8th gear at 50mph. May try sportive+ instead of sportive next

[@SpiderGamesHard]

@@przemekgodzik56 depending on which hybrid mechanically they will spool different. pure800 or the smaller daw turbos can spool pretty fast while the ultra flow will spool slower. Regardless, most tuners won’t give you full boost till 3500 even if the turbo spools faster to protect the stock motor. I’ve driven my og pure800 car for a while and like to be in d mode comfort around town and cruising on the freeway. It’s not undriveable but changing the shift maps would greatly help.

For those of us running stock, xhp ruined my car. It took away the hard aggressive shifts of the standard factory map in Sport mode. When I then tried to revert back to factory map, it took some updated stock map from somewhere....their servers.... And not the original map from my car. So I've now forever lost the enjoyable jerky shifts in sport mode, as well as the "fart noises" on upshifts. Total disaster.

If you want sharp gear changes you really need to put the car in Sport+ and to go in S mode (stick to left) or manual mode. For me, the shifts are crazy fast !
