Wanted to write a quick review on Stage 3

I have a 2013 335I drive with a JB 4 on stage 1. The transmission always felt like it wasn't matched to the car. Hard to describe it, it just felt off. Plus the kick down was terrible.

I was very hesitant to install stage 3 because i drive this car for work and sometimes with clients in it. I couldn't have some boy racer hard shifting transmission. I went with stage 3 on a hope.

Turns out its amazing, in daily driving in D, no one would ever guess this trans has been tuned. Even at full throttle upshifts in D, they are smooth and very quick. No jolt, no hard shift, nothing. It shifts exactly how it should have from the factory. M mode is incredible. It's like driving a stick, shifts are fast and smooth, and most importantly, they are done when you click the paddle.

Haven't messed with S mode yet.

Simply put, this is the best 200ish dollars I have spent on the car. I used an Amazon Fire HD tablet, and a 18 dollar cable off amazon. I didn't disconnect my JB4. Install was smooth with no problems.

To anyone on the fence, buy it. It's worth it.

Is development finished for the 135i? No more planned revisions to the OTS files?

Nothing planned at the moment, but that does not mean it will be so forever.

Just flashed stage 3 along with MHD stage 1.

The shifts are great but now my car feels like it lags, is not as responsive, and takes a lot more throttle in D mode and down in low RPM's to build power.. Anyone else experience something similar?

Did you choose the linear throttle option when flashing MHD?

If you purchased customization module, enable displaying gear on screen "Actual Gear" and see what happens. By default, I believe gear display is "target gear" to be shifted to

Also If you're picking up speed from 5-10mph range from braking, 2nd gear is probably engaged. Just a thought.

I haven't been on this thread for a while and have just read this post. It explains the issues I have encountered with my transmission. When the customisation mode became available, I purchased it specifically for the shift speed changes. I needed to improve my time down the strip by 0.04s to get into the 10s and thought slightly faster shift speeds may do the trick. I made the shift speed changes on the day I went to the drags as per the directions in the Manual. I had 3 runs with the best a 11.127s and the TCU through up a fault code for the 1st time and the transmission started to make some strange noises. After reading this post and realising that I had made the shift speeds slower instead of harder and faster, the cause for the slower times, TCU fault code and noises was obvious. The settings for shift speed were causing more clutch slippage. I have now reset the shift speeds in the correct direction and appears initially that the noises have gone. Whether the clutches have been damaged, time will tell. All due to poor management of the Manual content. It is imperative that the app and manual give the same and correct information.

No setting in the app is able to trigger noises from the clutches. It's not your clutches squeaking, it's your bushings being worn out and transmission's shafts having too much play. (common 6HP fault)

The setting is there for fine-tuning the shifts. Most noticeable for the driver is the torque-kick on shifts getting harder or smoother with that setting. But as said, that is fine-tuning. No way you can create a transmission fault with this setting, unless the trans is already at the fringe.

The description in the app is correct. The directions got reversed a few weeks after introduction because most users did it wrong, despite the description. The text in the app was immediately updated accordingly, but we missed it in the manual. Sorry for that.

Update of the manual is in progress!

MHD Tune and XHP Flash

New here and I have been trying to read up to find an answer, but so far nothing. I've been trying to read up and find out if I have to uninstall my MHD tune before going ahead and installing the XHP flash, or can I just go ahead and do it while MHD tune is still on car?

Nope, MHD and xHP are on separate control units so you don't have to uninstall MHD before you flash xHP. However, it is recommended that you re-flash whatever MHD map you're running and select the xHP option (for N54) or the manual option (for N55) so that the correct torque values are reported to the transmission.

I doubt the bushes are worn out in the transmission as it has only done 2,000kms since being installed and the transmission is a fully rebuilt and upgraded transmission. There were no issues with the transmission before the last meeting. Regardless, it is good that the manual is being updated so it reflects the same information as the app.

Thank you! I was thinking the same thing, but didn't want to jump into it without being 100%

Then someone went wrong during re-build. A trans does not squeak or squeal when properly assembled and clearances OK. Never.

I have a N55 X-drive with MHD installed. What should I choose as my transmission type, when flashing with MHD? Current manual on the xHP website states "Manual"

That changed, yes.

Note: Thats for E-Series N55. F-Series N55 will get an update by MHD soon to make full use of the removed torque limits on 8HP.

Hey, I want to carry out the XHP flash this weekend and i already have an OBD2 wifi adapter that works with my android and various apps, do i HAVE to have the THOR wifi adapter or would it work with my existing unit?

You have to have a Thor one. The generic Wifi Adapters are good for reading codes, but not suiteable for flashing.

Thanks for the reply!

Also, I have a pure stage 2 turbo for my 2011 N55. When flashing Stage 3, should I stick with only the version that has a “Single Turbo” designation (I think it’s ver 1.5), or can I flash the latest version?

You can use any of them, but we discontinued doing a single turbo version (only difference is higher shiftpoints in D), after we released the custom module. We encourage everyone to use the latest version and change his shiftpoints with the custom module, if he has the feeling thats needed on his setup.

e60 535xi N54 Stage 3 break-in?

535xi here. There's not a thread for this yet on any e60 forums. Just wanted some opinions on the behavior of the new tune (v.1.7)

How long does the adaption period take realistically? And is it a night and day difference once said period is reached? 3 to 4 engine cycles?

I have a 2008 535xi. 6AT. 90k miles. JB4 Map1, MHD back end, burger dual cones... nothing crazy.

Flashed Stage 3 last night. 50 miles logged today. Slow around town driving in D. Pretty tame. Too tame honestly. Not sure if it's supposed to be shifting down so soon.

By 30mph it has shifted to 4th, and is soon to go to 5th by 37 - 40mph. Sometimes 6th. It feels like it's really lugging the engine. I kept it out of boost.

Tune seems to keep the engine rpms around 1.2k to 1.6k and rarely to 2k. First gear I can get up past 2k. But it does not want to upshift when throttle is pressed until up to 60%-ish it seems? Going up small hills it does not upshift unless really provoked.

Then tried to get on the throttle a little bit more, but it was lugging hard and threw a code for timing over retarded. Shut the car off, started it back up and the code was cleared (which seems to happen to this car when lugging it, but due to the excessive lugging I'm seeing... it's just asking for trouble)

This is the video I took of a few take offs today, around the 50 mile break-in mark. Nice and easy on the throttle. No hills. 30 - 35mph roads. So, sorry its boring...


but maybe it's just my fatass 535... needing a walnut blast too. But it feels strange. I'll give sport mode a go tomorrow. So... looking for opinions and comments, what I should be experiencing etc.

I'll get more miles on it as the week goes by.
