How to make your N54 have a real hard cut REV LIMITER! MUST DO SETTING!

[@e9xn542]

So I have a 6hp with xhp, I used the shift bog fix and I gave it a few pulls on the way back from work and the power just feels way more linear, I’m glad I saw this

[@ZeroTo60Tube]

Thanks for the info!

[@motodigitalvideo]

I'll be reflashing with this setting when I get home. I agree MHD need to rename this setting, the default limiter is brutal and needs to be avoided.

[@ZeroTo60Tube]

Let us know how it goes!

[@zomski101]

Ken recommended me to check the shift bog on my auto with sutphin custom tune after I mentioned to him that my car sometimes didn't wanna shift from 2 to 3 after a very hard/lots of tire spin launch. Solved the issue ever since and has been fine going on just over 10 months.

[@skatepark02]

Is that Ken from Wedge tuning? I’m thinking of using him for my custom tune once I fit my 17T’s

[@zomski101]

@@skatepark02 Yes, he is an excellent choice, I had multiple tunes done by him for different setups and he always gets the car dialed in. Also probably has the most experience out of any other tuner in the n54 scene.

[@AsmirSut]

I have the manual and i had this option on, i always knew there was something about it and i loved it but could never figure it out but now I know. it's a huge difference on a manual car. Another one that boggles my mind is if you want to launch the car and pin the throttle in 1st gear it is also possible to activate the antilag while holding volume down and traction off. It's a huge difference a bit difficult to activate it every time though. I make my rev limiter at 4k and antilag and it launches like a rocket, it's amazing.

[@mikaeleriksson157]

I have been using this feature on my 335Xi MT ever since MHD released it, and I must say that the difference in how the car feels is big. But I didnt know it were a ignition cut, I was just amazed in how much better response the car had post shifts. If I do a fast shift above about 6500 rpm the engine keeps boost and the car continues like a rocket in next gear. I am a little affraid how my x drivetrain likes it tho.

[@N54God666]

Yeah see its super weird. I don't have this issue at all. Using this option or not results in the same feeling, stock turbos, td04 twins and my g30-900 single. Tune has always been by me so its far from amazing but everything works right

[@friguy4444]

I've been using "XDelete" app on my 2008 335XI and I love the choice of running full rear wheel only or all four driving if I want. Each has a different feel and way the car responds.

[@H4roBMX21]

I've never knew what the option actually did. But that makes alot of sense and got rid of my shift bog but I am a manual

[@KurumaDesigns]

I’ve always questioned this with your car since on my car I have abused the limiter a lot without any problems, good to see you got it sorted now!

[@Saif0412]

It rips through all the gears 🤯 I always thought that option was for MT cars only.

[@ZeroTo60Tube]

Me too….. 🙃

[@friguy4444]

Well cook my cranberries! I had no idea what you were on about in this video except for seeing the loss of power in the race shot you showed. But NOW that I'm running the 17T turbos I know what it does! It cuts right out and takes a second or so to come back in. I'll be checking this box tomorrow! Hopefully it'll work for me too.

[@ZeroTo60Tube]

Really from a UI perspective it should say “Rev Limiter:” and have a toggle between “Spark Cut” and “Fuel Cut”.

[@maxmoughal5183]

Awesome stuff, i bet you'll be going through all of those settings now, we need some new draggy runs on these and the AR1's!

[@kraazed]

Yeah it even occurs on my m135i running around 400hp, but to a lesser extent. I checked my MHD logs from the other week and in lower gears 1st, 2nd and 3rd, I see a torque Lim 2048 kick in every so often in the rpm range of 6600 - 7000rpm. It seems really inconsistent on the exact RPM but the lower the gear on the 8HP, the lower the torque lim 2048 kicks in. In 4th gear it tends to not kick in until 6950rpm, any wheel spin and the value is also lower than the 6950rpm. Might give this a check the next time I flash the car. I've noticed the car sometimes bogs on 2nd to 3rd change even if I shift at 6500rpm, and the XHP stage 3 flash did reduce the bogging a fair bit but it's still there.

[@andrewwilliams5337]

I appreciate you ready my comments. Even if they are trash 🥰

[@ZeroTo60Tube]

Hahaha lol. Sometimes they are funny and that makes it worth it 💯

[@all4bspinnin311]

On manual cars you can use it to flat foot shift.

[@jayjo6160]

i saw on a forum that this was bad for the clutches? is that true? might just go ahead and test it on my 335is.

[@ZeroTo60Tube]

The revlimiter wont effect the clutches.

[@ATStone]

I wish there was a similar setting for N55. Our limiter is terrible.

[@PartiBuoy]

So I do need it to cut off at 6000 to save on my stock turbos and I don't need it to drop so much so for me it might barely drop.

[@pugs1377]

Nice. I'll have to go try this!

[@rrokas]

On DAW flow max plus, 6AT XHP stage 3, car rips now with this setting enabled! Kind of scared if it causes damage long term, but I don’t drive crazy 24/7 so occasional abuse will be fine I suppose haha. 8hp swap soon. Can you flash xhp with the aftermarket TCU?

[@Pho6oZ]

huh... I had a shift bog (DCT) happening under certain scenarios in track, always thought it was due to the ECU map waiting for boost to come a bit lower since inlets and stuff (really need to get it custom tuned but damn lockdowns dont let me go out and do it), and it looked and felt exactly as you described it and showed it in the videos and rolls, I will give it a try when I can go out and report Ty for the info!

[@becausereasons41]

Is this fine to run on an auto trans then? I have index 12 injectors, my fuel setup can support 1000hp. I feel like I notice the lag in between 2nd and 3rd

[@ZeroTo60Tube]

You can absolutely run it on a auto. However it will only effect how the car acts at the rev limiter. Common issue on the autos is post shift timing corrections. If you are having timing drops just after a shift, your tune will need tweaking.

[@mulletor123]

I believe i have told you to apply shift bog fix on a couple of occasions ,even when you had issues over a year ago. Only advised for manual as aggressive limiters are not good on torque convertors.

[@ZeroTo60Tube]

Sorry dude, if only we all knew what it actually back then. Probably would have ticked it way sooner. I reckon i went to enable it a while ago and realised it was the longer flash then probably went nahhhh, ill leave it off for now.

[@kenvanbuskirk7034]

Maybe someone with the full knowledge of the workings of this system can comment on the possibilities of hydro locking a cylinder. With DME just cutting the spark and not the fuel is there a possibility at that high of an RPM(red line)for the fuel to build up and hydro lock? Or is that what the "pop" through the exhaust is that you are hearing ? Just a thought

[@ZeroTo60Tube]

It wont hydro lock, remember the air fuel ratios, hardly any fuel going in per compression cylce and then its straight out the exhaust port, whether the spark fires or not. It's how rev limiters used to work before direct injection.

[@andreazzopardi7311]

Are there any downsides to this? Increase in temps, or additional stress on the twins?

[@ZeroTo60Tube]

Zero. The factory rev limiter is a fuel cut for emissions purposes. This just changes it to an ignition cut which is much nicer on the hpfp system

[@andreazzopardi7311]

Thanks for the reply, mate! And really appreciate the content! 😁 I'm going for an 8HP70 and a Quaife LSD for my E92 335i and can't wait to finish it. Your channel is an inspiration.

[@torsteinhoel5708]

Is this the same as no-lift shift?

[@ZeroTo60Tube]

No its not. This really just changes the way the DME activates an RPM limit. No lift shift ideally needs to cut power enough to allow a gear change. Which needs to happen at a range of RPMs.

[@dillonabraas902]

Is this safe or even necessary for the non dct automatic?

[@ZeroTo60Tube]

It should be safe. But only worry about it if you car is giving you grief near the limiter.

From your experience is the jb4 with bef faster than say a mhd v10 stage 2+? For a FBO car with stock turbos?

[@ZeroTo60Tube]

No, MHD stage 2+ v10 is more aggressive. More timing on the MHD maps. You could run around 20psi with the JB4 in the mid range and maybe have it feel a bit more punchy. But JB4 Map 7 and MHD Stage 2+ = MHD more aggressive. Keep in mind each car responds differently, but looking at the BEF and MHD on paper, MHD is more.

@@dextershumba7262 If you wanna get really spicy the most aggressive MHD map is the V5 e40. TBH not many tuners can make a custom map run faster than that.
