It just has to be made a function of the ecu which is actually quite simple.

Or function of Nistune soft, which would be even simpler

I completely understand Matt, my comments werent really directed towards you and I should have said Nistune has potential to do launch control in the future. Just shootin the breeze.

I have recently had massive computer issues here at my place, both my laptop and secondary desktop had unrelated motherboard/cpu failures and until I can salvage the hard drives im out years of work.

Im running a loner and bored because I dont have my data, ugh.

Actually I got this idea a bit further - if maps could be switched depending on input, then we could programm maps for nitrous

It's always annoying to loose time, money or data...

Any chance of doing this change before summer?

Will be staying tuned for this change...

one I get Type 4 / 5 board updates out of the way and knock sensing stuff then I can have a look at this... seeing there is some demand for it

it lowers your rev limt when you press the cluth, so you can keep the gas floord when you shift gear

And can destroy clutches

These features are in the list. They will require firmware changes and use of auxillary inputs/outputs of the ECU to perform

Its been a few months since the last post... any free time to implement this feature yet????
I would LOVEEEEE to have this feature!!!!!!!!!!!

sorry not yet. this is towards the bottom of the list at this point unfortunately. knock detection stuff will be coming firstly

I have try to do a simple lauche control/flat shift with nistune:

- You need a small push button (like an horn button) => fix it on the shift knob and bypass the neutral switch sensor (on the gearbox) by this button.

- When you maintain the button on, the ecu think you are in neutral and use the idle gear timing map.

- You just need to put 0 (approx. -16 of timing) past 4500 rpm and you have a lauch control/flat shift option)...

It also do a little antilag when you release the gaz ...

Someone figured it out for the SR20DE fwd.

I have read the article above. Very good work!
Is there a chance to use this solution with NIStune on a SR20DET (82F08)?
I think this results in a new burning of a modified Base-ROM. Am I right?
