Do you have any solution to flash the gts sw to the new m2c ?


I also have the GTS tsu flash for a week now and I experienced the same thing, my car also doesn't show the selected gear on the dash in drive mode. I tried flashing the tcu back to stock and the transmission display still doesn't show!! They need to find a fix for this...

TCU flash is factory software from the M4 GTS. We're looking at possibilities around customization of it but there are a number of hurdles there that are holding this back at this time which we're working on among other high priority items/updates. The sole purpose of the flash is to raise line pressure to the clutches at higher torque levels and maximize their clamping force.

I'm glad to hear that you are working on a fix, cause it is really annoying to drive without seeing the display.

I have a M2C W/DCT, Would it be wise for me to not flash the TCU at this time?

Planning to do either CS+ or stage 1. Does the TCU flash go hand in hand with

the ECU flash?

Wait for PTF to post an update, I think there's some small differences with the other guy that lives in Lebanon.

I would run CS+ or Stage1 at your will should be a great upgrade

The GTS DCT Flash is not exactly needed on stage1 tune, maybe more noticeable with Stage2 and Higher tunes depending on your driving habits too.

Guys, the GTS tcu software works perfectly fine on our cars despite the display issue in drive mode. Other than that, the shifts are noticeably faster and more responsive which contributes to the longevity of the clutches since the clamping force has increased.

Yup, manual mode shifts perfectly from the paddle shifters and gear lever.

How could you make it work?? We tried 3x times and after 2-3mins at testruns the gear level indicator in the dash dissappeared and after that the manual mode didn't work! Only automatic... What could be the solution?

It was working fine the moment I flashed it, the only problem I encountered is the display issue in drive mode. Other than that the car shifts flawlessly in all modes, I'm sorry to hear that you have a problem with the shifters.

Do you see the gear display in Manual mode?

Did you flashed it via ESYS ?

Sorry for the questions, but as far as i know you are the only one who can make it work on the M2C...

( Sent you a pm also! )

Should people with a 6MT have any concerns flashing their M2c's?

I recently watched this youtube video and Tommy from this youtube channel flashed his F80 6MT M3 and after flashing he could not drive his car correctly. Lots of jerkiness with the 6MT and the tune together.

He has actually flashed his vehicle back to stock and not running a tune due to not being able to drive his 6MT M3 correctly with the tune.

Is this issue corrected with Bootmod and 6MT owners?? Are these tunes developed for a 6MT or DCT vehicles?

BPM's stage 1,2 tune is apparently smooth for 6MT as they did several revisions on their maps for 6MT to smooth out the throttle response...

Not sure about BM3 but I might be wrong as I don't recall seeing PTF ever clarify on whether their tune works well on a 6MT.

Wonder when the OFT will be released for the M2 & M2C.? I was told by Anthony that they would support our cars. First the M2 ....then the M2C. No timeframe though.

It’s good to have options. I know a lot of guys who had multiple tuning platforms back in the day. JB4 & Vishnu had epic battles. Maybe more of those wars played out for the S/55.
Waiting & seeing.

Maybe this should all go in another thread though....this one is for BM3,no?

Full support added including access to all of the S55 OTS maps that have been tested and refined through bootmod3 since 2015, now sitting at Version 8.5.

These maps are identical to the other S55 OTS maps and that includes the FREE CS, CSL and GTS maps as well which you can import in the editor and compare with your own stock M2 Competition map if you're inclined to see and learn about the difference factory takes in tuning, or should we say 'detuning', your S55 motor.

Any questions let us know, all the best
Just flashed the CS map to start with and turned off cold start today .

Nice, how does it feel when compared to stock? Is your car a DCT or 6MT?
