If only MHD allowed a "stage 0" tune for preventing the catless CEL. I have no desire for more boost, but I want downpipes for the sound

Yes, but your DME has to be unlocked. Justin @ Twisted Tuning provides this service with a quick turnaround time.

There is a stage 0. You need the Flasher License though.

MHD Tuning , Twisted Tuning, @anyone els that can help.

In this thread in the California sub forum https://www.1addicts.com/forums/show...6#post25431986 there are a few people that failed smog even though MHD was removed from the vehicle. Some people have heard it is due to a mismatch in check sums which can be seen after flashing the dme.

Is the non matching checksum the reason for the error showing up during smog? How can can we make them match?

Thanks

Helping a friend out with his E-series N55. MHD Tuning Twisted Tuning

Flashed MHD Stage 2 (95 Ron) and the car feels significantly slower than stock afterwards. Only code present was a "32C9 - Poor road surface detection" which I assume is unrelated as it has yet to come back...which I found quite odd considering how dead it feels.

Car was flashed via a cable I've used many times on my own cars, but with a USB-A to USB-C converter so he can use his Huawei phone...not sure if this is perhaps relevant.

P.S. I realize logs would be an advantage but I'm just checking if anyone has perhaps encountered the same issue and found it to be related to something going wrong during the flash process? If not I will insist he buy the monitor module and run some logs with him.

P.P.S. Flashed it back to stock afterwards (full flash) and still feels dead. It seems,to me at least, that something happened during the flash that has screwed something or other up.

Hey there fellas, Is one of you geniuses able to check out my log.

Car was feeling slow so I thought there was a boost leak, not too sure maybe something else it wrong?

This was a 3rd gear pull.

Info on car DCT 98RON Stage 2+

Here's my datalog from MHD, hopefully I've done it right.
https://datazap.me/u/matankau/data-3?log=0&data=4-20

Would appreciate it alot of someone could let me know if the car is running normally.

Thanks in advanced fellas

Hey all,

I have a question about MHD logging on the N55 platform. I noticed that when my car is idling boost PSI is reading either 0 or 0.1 is this normal, or do I have a vacuum leak/wastegate issue? I know other platforms tend to show vacuum pressure via negative PSI on the boost gauge (typically around -14 PSI), and have even seen negative PSI readings on the MHD logger on N54s.

Is this normal for logging on the N55 or do I have a legitimate issue? I recently tested for and fixed any boost leaks (to my knowledge) so this is puzzling.

Thanks

I've noticed the same thing too and assume it's normal. The N55 added valvetronic variable valve lift and duration control which can take care of the throttling of the engine instead of a typical butterfly throttle plate (N55's still have a traditional throttle as well as a safety measure). Now this is just an educated guess on my part, but I assume that because of this system, the throttle plate can stay fully open even at idle, which means that the intake manifold pressure should be almost equal to atmospheric pressure, or 0 PSI-gauge. This is likely done for 2 reasons:
1. Efficiency - pressure losses across the throttle are an area of inefficiency in gasoline engines. Throttling with the intake valves is a more efficient way of controlling airflow.
2. Transient response - With the intake manifold already at or near ambient pressure during low-load/cruising, it will likely take less time to reach target boost pressure than an engine that is starting with a vacuum in the intake. i.e. going from 0 to 10 psi can happen faster than going from -10 to 10 psi. Just spitballing here, but this may have been another part of the justification to go from twin to single turbo between the N54 and N55.

Other platforms that use a throttle plate for airflow control at idle (including N54's) will have a negative pressure in the intake manifold as you've seen before.

This issue has been floating around a bit on the forum and I haven't seen much traction with it, so thought I'd bring it up in here. Issue is with the new flash that has allowed the locked DME for late E series to be flashed without bench flash. We are currently running into an issue with throttle spike when applying around 10% - 15% throttle. Just want to see if anyone knows of a way to flash a previous version? Or if Twisted Tuning is aware and is working towards a fix?

Iím finally in the MHD club......thanks to v1.7 OBD unlock.

Using a Kindle Fire 7 and the WiFi adapter, I was able to load the BMS BEF straight from stock in 6 minutes 28 seconds.

So from what I have been reading MHD tunes aren't as powerful as bm3,

There website advertises 400hp on 2+ for the PWG. is that not accurate? N55 platform

I have this issue as well and a few others. I'm on e90post trying to get support from Twisted_Tuning.

For some odd reason I posted here instead of F series lol

Hi guys,

I just updated my 2013 135i DCT on Stg 2+ from 1.6 to 1.7 and am noticing something is up with the throttle. It has a mind of its own. Being a late e-series, I can't downgrade...

If I keep the throttle steady, the car accelerates and decelerates on its own.

Any ideas on how to fix this?

I did the 1.7 unlock the week it came out. I noticed the runaway boost right away. Iím running MHD with JB4 BEF so I was able to dial back throttle sensitivity to get things under control

However, there have been 3 times after that when moderate throttle in 2nd hear has given me 22 and 24 psi boost.

Definitely something fishy with the tune.

Is it possible to register a new battery (same specs) with MHD without buying a module?
Can someone confirm this can be done for free?

You can register the battery for free with MHD. You will need to make sure the specs are the same as the old battery. If not, you will need to code it with Protools, BMW Standard Tools, etc.

I like the power I have now but the transmission seems to be having issues with the added power. It downshifts to almost redline and then takes a couple seconds to shift to the next gear. I am disappointed with the shifting. Can the MHD tune help with this.
Deactivate kickdown and the car will not down shift like that. You can disable kick down when you flash the tune, but you will have to do downshifting your self.

Same deal on my X1 35i. I'm going to log and send them logs and test a revision. Don't worry too hard they will definitely fix it.
