How to make your BMW 335i Auto shift like a supercar (Xhp) 

Send it!

I feel you, my 335i is the same way. You just gotta find the sweet spot that the car likes most to shift at, once you find that the shifts will still be aggressive but won’t be as jerky as normal when you don’t use the paddles

For sure one of the best mods you can do your BMW!

Holding up well!

Disable torque bog for (MT) through MHD! I did this and it made a big difference.

@@Kamshaftcould damage the trans no?

@@3dirty5xi honestly man I’ve been running this stage 3 trans tune for 2 years now (40,000km since the trans tune) and for 1 year I’ve been single turbo putting down 550whp and the trans still shifts amazing! I also beat the hell out of the car. Another note, auto transmissions are very cheap and easy to find for these cars, no joke they are $300-$500 used with low km. Make sure you service your trans oil and filter with genuine parts and fluid, the benefits are definitely worth the risk.

I actually did service my trans a bit after making this video & it made it even shift better! I am now servicing it again and this time also replacing the shift solenoids & mechatronic seals, cost over $1000 just for all the parts & fluid.

​@Kamshaft doing that this week fingers crossed 🤞

@@Louie_E92 it’s pretty straightforward, you got it! Keep everything clean and work safely! I also highly recommend OEM (ZF) seals and fluid. I ended up having to redo my work down the road as the parts I used were aftermarket and leaked.

Still incredibly fast for an A/T how much faster can the shifts get lol! Could still bump up shift speeds but I enjoy where it is at!

@@fry.master thank you for this comment, I love it when educated individuals talk facts! When you say “Race mode” do you mean like once you shift the car into “sport” with the gear shifter?

@@Kamshaft sorry no, it’s a separate flash option within XHP’s stage 3 or 4 configuration settings.

@@fry.master if I enable zero torque reduction would this be extra hard on the transmission? Just curious

@@Kamshaft xhp’s tooltip in the setting itself claims “4x more clutch wear”. I believe this to be a massively wide approximation. There exists a balance in shift speed / force to find optimal clutch wear. Think about it: slipping the clutches is what wears the packs. So faster shifts mean less time slipping, but the harder force means the slip that does happen is more damaging. This ratio also changes depending on torque load and vehicle weight…. I digress. Main point is, not reducing torque output during the moment of shift is going to put a massive shock load on your clutch packs. This shock load sometimes might bite perfect with a crisp tire chirp, and feel like a monster making you want to do it again. But as soon as they slip a few good times doing that, they’re gone. I would only recommend that mode if you were going for a PR, had a very overbuilt transmission, or just otherwise needed every ounce the car has for a single race.

Yes! They make for a perfect combo.

Depending on what license you buy, it comes with a flash or all of them.

But the whole pack. It’s worth it so that way you have way more options to learn your trans.

MHD wifi adapter

@@fredsalfa Definitely not

@@Kamshaft How come? Will something else work?

@@fredsalfa Because a BMW transmission tune will not on a Mercedes, this is what you need www.vrtuned.com/tuned-ecu-flash-tune-mercedes-slk350-35l-r172-306hp-1116-p-152456102.html

@@Kamshaft Oh Wow thank you! I never even knew I could change the shifting on my car till I saw your video😁

@@fredsalfa that tune will help will your engine performance and throttle response, but not shifting. I can’t find any tunes for the transmission on your car.

You should get both at the same time! But it is not really that crucial, your car will be ok if you have MHD and not this.

I’m really not sure, your best bet is to reach out to XHP and ask.

In france we map 25d 30d and 35d, I’m pretty sure you can do it

HKS BOV & 3” aluminum charge piping

definitely due to the holes in the hood. I have a turbosmart BOV that sounds the exact same when my hood is open but is muffled by the regular hood when it’s closed.

@@Kamshaft was debating over hks charge + ssqv or just getting the cheapo pipe that comes with a fake tial and getting a real tial later. You 100% made up my mind with this video lol. That ssqv sounds so damn good. Been about 8 years since I had one (the sqv v3 had just come out recently, and hadn't been faked yet)

@@EvlEgle glad to hear that! The iconic sound never gets old! BOV is still going strong 💪

Stage 4 is a super aggressive map for auto mode only.

owner of a tuned 335d, id assume steptronic if yours has that?

@@murph7501 Yeah my 330D has the xhp software. It has the zf6hp gearbox i believe

It’s a 335xi but tuned with X-delete so AWD/RWD can be configured at any time.

@@RutherfordMichaelia-z8l yes

I actually did after installing the single turbo, made a big difference.

DIY hood vents, used a grinder.

Not hard enough

Lol

While I’d agree with you because I enjoy manual more than Auto and I’ve owned ONLY manual. I myself have a 6 speed 328i. The automatic in the 335i is better because it keeps you in boost when you really get on it, it’s faster because of that.

100% cause you are not tuned. Tune=more BOOST! More BOOST= more cool turbo sounds. I have also flashed my car back to stock and the noises it makes are not even comparable.

@@Kamshaft can confirm, just went stage one and it’s wayyy louder. Plus I fixed my wastegate rattle on acceleration

@@Kamshaft hey, i have stg3 Trans map also, but i have much vibration on shift, really agressive "clutch dumping" feeling. Do you have same?

@@freemail6284 when I first flashed the car it shifted really heard for the first 50km or so, you supposed to let the TECU “adapt” for a bit.

U might be acoustic

@@somith2329 I’m having trouble understanding what you mean, could you please elaborate on that?

@Kamshaft 3-4-3-4-5-4-3??that was so painful to watch man.just put it in 1st gear Rev it 2nd 3rd then 4th gear Rev it out from a dig.do the same before and after so you can see a clear difference

Your changing gears way to early dude

@@somith2329 well I’m demonstrating the speed of the shifts! Not the acceleration m8, I think you should make a video if you have such an issue with this one. 😂
