Thank you so much man

This clarified a bunch! Back to the garage, thanks!

14:19. It definitely works on cold start for me. The only time it doesn't work is when I'm on an incline. It works every other time (M240i RWD). When the transmission is cold the 1-2 shift can be quite jerky at low-partial throttle, this is why I activated this setting. It makes pulling away from a stop much smoother and more relaxed.

[@Y.D.43210]

Excellent overview! More comprehensive than Part 1 :)

[@vrp93]

Thanks man! I have a G30 540i and was looking for trustworthy information before trying a xhp tune

[@clmbiano]

What else do you have on your car? I have a ‘17 G30. I’m MHD stage 2 plus with the XHp. It was a total game changer. Without it the additional power didn’t balance well with the transmission.

[@dougcoffey3496]

Thanks for this! Awesome video, and makes me feel much more comfortable messing with my XHP settings now

[@kern417]

Glad to help

[@MeadorRacing69]

Ty for these videos. I just got xHP and needed better explinations of all the options and you came up! thnaks!

[@Ryan-cx7gb]

Hey, for someone after the loud brap upshift sound increasing torque reduction seems to be the key if I’m getting it correct. I was just wondering in what increments should I try raising torque reduction upshift between gears to get what the loud upshift sound I’m after? Or is it better to play around and see. Regardless if you have a number I should start at I would appreciate it! Thanks man

[@kern417]

I really appreciate the support. And yes, the torque reduction will give you what you're looking for. Start in the middle and slowly go more aggressive until you hit the sound you like. I would only increase it as much as you need to. It can slow down the shifts and affect performance.

[@JohnsonMotorsports]

What about the ignition cut shifting, is it safe and what settings should I do

[@omgitssmike]

hey how’s it going I’m having trouble with slipping from 4th-5th gear is there any settings that could help besides bumping the line pressure it works sometimes but the car is stock no tune just downpipes and intakes what would u recommend also my xhp settings never seem to save i have to flash my settings every time i get in the car

[@omgitssmike]

i have n54 btw

[@kern417]

If your transmission is slipping on stock tune then make sure your fluid levels are not low. Otherwise it may be time for a rebuild/replacement.

[@Rocketman_205]

Idk if I’m the only one that has run into this issue… I have a 2017 540i 40k miles with MHD stage 1 (for now). All maintenance is up to date. Bought XHP, flashed the car, get a flashing CEL but no error codes. Uninstalled and it went away. Tried to reinstall same thing. Anyone have an answer for this?

[@fongfuning3564]

Nice video. Your explains more details then the others. Thankks. One question though. Does it need to flash the tune everytime you change the settings?

[@kern417]

Yes you do

[@Dardania07]

i would not touch the custom setting but let the tune be how it is, it is already very well packed.

[@DrewEckman-n4t]

maybe on an Xdrive it is good as is... but on my RWD (MHD stage2 on E30) the stock XHP stage2 can't put the power down, not good enough traction and the traction control in Sport mode constantly cuts power. But the custom settings are hard to figure out. I should have gone X-drive. :o(

[@justinishaq7555]

So for the fastest upshifts I turn the torque reduction to negative 50?

[@BigBlueRacing]

Good info

[@turk1998]

So torque reduction function if i put the slider to negative it can make the car faster right?

[@kern417]

It just depends on if that's even a limiting factor. If you have other Big Turbo then possibly

[@DrewEckman-n4t]

Can anyone recommend the optimal custom XHP (stage 2) settings for my RWD 340i MHD stage2 on E30 blend? I'm running always start in 2nd Gear on and some torque reduction but the car really has trouble putting the power down on my 265/35/19's in the rear. Even in Sport mode the traction control constantly cuts power as it loses traction. I really regret not getting X-drive.... Also should i go to a 275 or 285 on 18's for better traction?

[@JustLuuchi]

Do you recommend using torque reduction or staying away ?

[@varsity2845]

Do you think Throttle Blips will wear the transmission? I love driving it in manual mode in my 2022 M340i and I have my Throttle Blips all set to +35% it’s so addicting hearing the downshifts. Also put my Torque Reduction all to +10%. I’m only on JB4 since these are locked ECU. Just curious because I don’t wanna blow my transmission either.

[@kern417]

Nah it can handle it

[@elmontii]

⁠@@kern417what about 15% for the torque reduction on a stock 2021 M340i

[@elmontii]

what stage are you currently on ?

[@blacktalonsport1262]

Would adjusting the slides help prevent the car from going into limp mode during hard launches on a prepped surface?

[@kern417]

No, that just adjusts how much power is sent. There are still limiters that can put the car in limp in certain scenarios

[@tristanmayor6302]

Would be so good if you could have different settings that you could toggle through like you can with the ECU tune eg MHD. Then you could select valet mode on/off in a couple of seconds

[@kern417]

Yep somehow make a map 5 the valet mode

[@tristanmayor6302]

You could even have a 0% power mode as an anti theft setting. I've even suggested this to MHD in the past

[@kern417]

@@tristanmayor6302 worked great on my APR tune on my Volkswagen. And you could even lock out map switching so if someone knew how to do it they couldn't switch maps

[@STAyTHIrstyMyFREind]

Make the map you want and export it (three dots in the top right). You can export as many maps/setting configurations as you want! Like Race Mode or Valet Mode. Makes flashing for every scenario a lot quicker! NOTE: Export/Import only works in the editing window for some reason. If your in the stage selection window, export/import will fail.

[@EraBoyz]

Just to clarify since I may have heard you wrong. Is there a limit to how many times you can flash your transmission. Great info thanks

[@kern417]

No way jose

[@DWNFRC]

Great video as always! Any idea to what level the torque on 6th gear should be limited to?

[@kern417]

600ftlbs

[@dougcoffey3496]

@@kern417would you do 600 for 3rd as well? Do you think 3rd is stronger, or simply not as necessary unless you’re hybrid turbo? I’m thinking engine torque could get higher than 600 even on stock turbo with some of the dyno sheets I’ve seen being 550+

[@kern417]

3rd is stronger than 6th but the limit just depends. Not many go that high on stock turbo without port injection

[@JustLuuchi]

Has anyone used these settings on N55 ? are ZF8 transmissions all the same ?

[@the_batmobile0.4]

Xhp now offers custom tune for zf8hp50 auto, do u think it's worth getting it?

We'll be talking about it this weekend

[@itswhip]

Do tunes like Xhp or even BM3 recognize 'Sport Individual?' Or do they need to be run in Sport or Sport+ to work properly?

[@kern417]

Not sure, I don't have that option on my car

[@NigelDRealest]

11:34 Why can't you flash your transmission too many times?

[@AlexJaramillo-m6v]

He means that you can do it as many times as it takes to figure out exactly what you want. It won’t hurt the car to flash it a bunch of time.

[@MajorBuzzKill]

What if my car doesnt have launch control will this add it? i have an f20 bmw 125d 2013

Just set torque reduction in your tune

[@maxserhiienko5648]

Will drag mode work in the D mode of the gear and Sport+ of the engine?

[@kern417]

I believe any trans mode as long as you're in sport + or dsc off

[@hialeahhigh]

Is the drag mode feature automatically turned on? On the stage 3? Or does it have to be turned on before you flash the tune?

no you need to enable it in the options

not really needed unless you're pushing the limits of the trans with a tune that isn't reporting torque accurately.

Does the Supra not have the soft shift mode I don’t see it on mine

[@kern417]

I'm not sure. I would have thought the options are available for both

Great videos, the most informative I've find with regard to xHP software. I have one question, new user of xHP I try to do my custom maps. I cant notice any change of ZF8 transmission shifting, BMW F30, until the transmission is fully warmed up. It seems that xHP maps are not active and stock map is on until transmission fully warmed up. Is that the case, as it was meant to be?

[@N55Koby]

i wanna try drag race mode from a 50 roll to see what ill get, but my trans is already experiencing torque limits in 6th gear should i try it one time?

[@kern417]

Torque limits in 6th aren't much of a factor specifically. What's your mileage/maintenance like? No fluid leaks or anything?

[@N55Koby]

@@kern417 60k miles i have a small oil leak but i dont think anything from the transmission is leaking

[@kern417]

Main thing is making sure the car is in good condition and up to date on maintenance. Still no guarantees but that reduces the risk

[@VDUSoulja]

Is there a way to eliminate the upshift farts completely?

[@kern417]

I believe reducing torque reduction on shifts will help and dial back shift aggression. No matter what the car has to cut power when shifting and that's what you hear.

Sounds like you need a Lexus if this is to much for you

[@maoda4778]

[@yanisbondar]

What is the current only way to get more power out of POST 06/2020 produced b58s. So like for example a 2021 m340i. And are there any companies working to figure out a way to unlock them without having to send them to femto? 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?

[@universalg_]

Femto is unfortunately the only way at the moment to get your ECU unlocked. JB4 technically gets you past the stock power levels but it isn't a true ECU tune (piggyback) like MHD or bootmod3 would be.

[@peepstar8773]

As far as I know there are no companies publicly working on unlocking them. Downpipe JB4 E30 is basically the limit without sending your ecu out.

[@yanisbondar]

@@peepstar8773 mission performance tuning has apparently had it unlocked for over 6 month now. They posted on a discussion posting in may of last year with an attached video for proof that they unlocked it. But they said they will not release it to the public until another reputable company unlocks it because they don’t want other companies to copy their technique and take credit for unlocking it. And I don’t see mhd or bm3 making any strives to unlock it. Very annoying

Drag mode doesn't do anything in that scenario.

Does the launch control setting only affect using factory law control or does it also affect break boosting?
