Reverse engineer 765LT launch control...?

So who is going to be doing this so that we can apply that to other Macs, like the 650, 570 etc?

Lets be honest, however that launch works is BOMB, we need the recipe for other models now......

I don't know if the actual launch mode has changed at all. Drag times was cutting a 1.4 60 foot time which has been done by many 720s as well .

Difference is the rolling burnout mode in the 765lt to warm up and scuff the tires vs the 720s to achieve those 60 foot times need tire warmers .

Mengineering to my knowledge is going to develope a rolling burnout for the 720s and other models.

My 12C is yearning for better launch control scripting in the ECU.

PLEASE M-Engineering! Please reverse engineer this for all the P11 models as well !!!

Yeah im of the opinion that the 12c launch SUCKS if you have more power added, stock it might be okay, but it suffers badly in the launches when there is more power in the 838T

765LT has entirely different gears

Correct! The Final drive ratio of the 765lt is 15% shorter than the 720s. Not to mention the 765lt has lighter forged pistons higher boost and an additional fuel pump. It's not just a simple software change that allows the better launch in the LT. Hardware accounts for much of the difference in my opinion. That's why highly tuned 720s cars haven't run as fast as tuned 765lt's.

That said, the 765lt does seem like the launch rpm is closer to 3,700-4000 rpm where the 720s seems closer to the 3000-3300 rpm range.

Just started tooling around with ‘Rolling Burnout Mode’ on my 765LT and damn does that feature put a smile on my face.


Absolutely should help when attempting 1/4 mile times.

Hi guys,

Im surprised that this hasnt already been mentioned, but there are some changes to the LC that can be made in the engine ecu, but this is mainly launch RPM and torque applied to the clutch when the brake is released...

No doubt there will also be some TCU changes as well, but for what its worth, you can really increase the launch torque on the earlier 12c and 650 models, its important to remember that a certain amount of slip is a good thing, otherwise the gearbox is taking a lot of torque, thats the while reason why some slip is good as well.

Thanks.

What are talking about ? Hasn't been mentioned ? Lol

Not to be rude but did you read the thread at all . That's what this thread is about , Mengineering has adjustable Launch Control and rolling burnout mode for years now .

I could set what ever rpm I wanted my launch control to be used at

Wheres it been mentioned? Because the OP mentioned 765LT LC to other models. I wasnt talking about anything else…

FYI, you wont be able to get true 765LT launch control on any other mclaren, probably ever. Theres too many maps and parameters to get heads to sort it.

Love it when people comment who havent a clue how things like this even work. Yes of course m engineering have, but where is it mentioned in this thread?

Smart ass, im off to tune a senna. Peace

Shut the f*ck up , go look at post 22 and above its being talked about. Saying I don't know what I'm talking about is laughable and by not reading the thread you just made yourself look like an idiot calling me out when it's just a few posts above.

Have fun with your senna tune , love you throwing that in 😂😂

Also side note , you are wrong saying you won't get a true 765lt launch because of the ecu parameters are to many .... it's cause of one reason only and that's hardware . The transmission/gearing is different and that's the only reason it won't be identical

Another shit head to add to the forum list, I thought you were respectable, seems not. Post 22 "Mengineering has already done the rolling burnout and adjustable launch mode for the 720s . They displayed this feature at Tx2k last week"

Really informative that lol, thats why I posted what I did as it doesnt mention any of the other models does it?!?

No one here will be able to reverse engineer the TCU fully without documentation, which doesn't exist out in the open, but I really hope someone spends the time to offer 675,570 shifting to the 650 and 12c, because that is REALLY needed, having been involved in this with other cars and even programming it, its really not easy to do, you have parameters such as:

1. Shift pressure
2. Torque maps/engine and gearbox
3. Clutch parameters and a whole load of other things.

No, you don't know technically how this works. if so, post up the torque maps for LC which is the most basic thing ever to the initiated.... I can call you out because you dont have a clue at a technical level. Just Leymans terms, I know this for a fact as there are only a few who know.

Man the level of rudeness on the forum us really unpleasant.. I came onto this forum and noticed there was a lack of info available there was literally only one company who was offering any kind of information and they know who they are.

Good luck to you.

You thought I was respectable.... OK let's look at how this started ...

I posted , respectfully and said .. " Not trying to be rude but ... "

And then you respond like a 12year old with nothing but disrespect by saying

"

Love it when people comment who havent a clue how things like this even work. Yes of course m engineering have, but where is it mentioned in this thread?

"

Now let's ask ppl here who is the disrespectful troll on the forum . I have provided an insnae amount of help and information on this forum for about 5 years now and you instantly call me names and say I know nothing after I was very nice and just said hey not to be rude but it has been posted before .

If I was a new potential customer reading how you carry yourself I would run so far away from you and your business .

So once again fu*k off . Disrespect gets disrespect. YOU started that part not me
