Those who’ve purchased, is the manual mode quicker? Any changes in engine sound at all? (The standard box changes lead to some nice upshift cracks at certain revs).

Also interested in the ‘torque punch’ and whether it improves the driving experience.

Gearbox seems to be very fast in every mode. S3 is very quick. D3 is very quick but in my opinion d3 from stage3 map can be used only on track or roll race because car change gear at almost redline( this can be adjusted by parameter)
The most exciting option for me is i can raise shiftpoints
I cant run dragy now because my rear tyres not grip anymore. My toyo are out. But i feel i can lower 0-100 from 3.7 to 3.5-3.6

Thanks. I’m more interested in shift speeds and if it’s a noticeable increase given the price for this software. I’m not a drag/roll racer, plus I also don’t drive in D when driving fast, so the benefits may be lost on me in that respect.

I know the M DCT isn’t like Porsche’s PDK, but I’d be swayed if it bridges the gap closer

Manual mode, dsc off are the quickest shifts. I haven't had an opportunity to play with torque punch yet but likely next week. It's mentioned that torque punch and reduction may need to be adjusted together.

I really cannot see how the XHP stage 3 shift speed can be faster than the Thor GTS flash given clutches and hardware capabilities.

The key take home is that the clamping pressures are elevated to take up to 1100nm of torque which is very useful for aftermarket turbo set ups. Increased clamping pressures = banging into gears harder

If you are sticking with stock turbos on e85, the THOR GTS flash is sufficient.

Thor GTS flash didn't work on the 18+ cars if I recall correctly. Many users also reported very poor customer service and communication. I definitely never received any intelligible answers regarding questions that I asked them.

This being said you cannot really say anything about comparing Thor and XHP shift speeds without trying both...and neither can I. In regards to the "increased clamping pressure = banging into gears harder" comment, this is incorrect as the torque reduction/torque punch settings are what affect that...the clutch pressures increasing are what affect the clutches "ability" to hold the torque on the clutches in gear.

So to simply say a "Thor GTS flash is sufficient" is in my opinion, a load of hogwash. At the end of the day the Thor was right for you...for the rest of users, it will depend what they want.

Ordered mine yesterday, mhd flasher shipped today should arrive by Monday or Tuesday so I'll report back!

I just want faster shifts,I mean if you can feel it shifting faster that's good for quicker times as well!

The extra clamping force was a no brainer for me get it now so I have it when I go bigger turbos.

For now I'll enjoy the shift speed.

Can someone explain what torque punch 🥊 is?

not sure what it is, I'll give it a try tomorrow though. I'll report back when I'm done with it. I've been having too much fun raising launch control lol.

I wanna pick your brains here. I'm trying to understand what a "spongy" shift feels like. I always thought the DCT was sharp when it comes to shifting. At what point is it considered spongy?

Spongy if you feel the car take longer to get back to full power after the shift. The throttle will pinch back to around 70% during the shift(as it should...XHP has mentioned disabling throttle on shift is the wrong way.) Throttles pinch to reduce torque, but sometimes this can feel spongy like the clutch hasn't fully re-engaged after the shift. Torque punch is a multiplier; play with it and see it for yourself; it's pretty self explanatory imo. I increased torque punch to 5 today and Tq reduction to 650...felt great. I'll continue playing as opportunities arise.

How does it help improve traction when using launch control?
On the street I spin my wheels like there's no tomorrow.

Can it change launch control mode so I can manually shift instead of allowing it to automatically shift? When I do manually shift, it will upshifts twice and mess up my quarter mile.

How does it help traction control from cutting too much power with little slip? I have an M3 F80 at about 700 whp, and when I break traction on a straight line, even just a little, my car almost completely cuts power. Can it "balance" the wheel slip and power output better, so it doesn't fully cut power?

Also, with regards to Kickdown Launch... When I may the gas pedal, it engaged at 4000 rpm. Can this allow me to drop it to 2500 or so, since there's minimal traction on the streets?

I simply feel that other cars are better from the dig and really put down the power instead spinning too much. Spinnin ain't winnin!

Your tuner needs to reduce your torque in 1st/2nd if you're spinning too much...or stickier tires. You can adjust launch rpm but can't shift the first couple gears as that's programmed launch control from factory.

You can adjust the kickdown rpm settings yes.

Does the stage 3 map shift any faster than Thor GTS flash?

Does this new tcu affect the factory nannies that pull power during launch control and slip into 2nd gear?

Hi

1. What are the perfect settings for 100% grip want to lose as little traction as possible when standing still !?

2. And does anyone have a good setting for 100-200?
With regard to switching time, I want to drive the best possible time in D3!

3. What do you recommend? I am open and grateful for all suggestions and information.

4. Regarding launch control, which speed is best suited for this?

5. Sorry for my english translation with google.

thank you

stage 3 is too aggressive. especially the downshifts (watch out for the crank hub). Stage 2 for me is enough for me. I am with bm3 stage 1 91AKi. many options to customize.

its a great tool, from now on you will see over 25 F80 F82 into 9s quarter mile because launch control and boost could now are part of equation ...

Just downloaded and shot a quick how-to download and 1st impressions video. Will post in a week or so.
Important question though... Does anyone know if xHP overrides BM3 custom boost reduction for gears? I simply flashed OTS Map 2 of xHP, touched nothing else yet, and I just feel like my 1,2 gears are torque-ier than normal.
I see that xHP does have their own option for torque reduction... how would that work if it's setup within bootmod3? Which one takes precedence?

Last flash likely takes the precedence for the affected maps.
