Timing would be the best way to cut torque on shift. The ECU has the logic for it already in place, but for whatever reason it doesn't work the way it needs to. It's like they set it up to be able to do it, then decided to not use it.
That's what the Euro cars do. Its what they get the nice clap/burble noise on upshifts.

One of the cars testing with a GSR running GTX3576R managed to make 8-9 PSI with spark cut set to 5000 compared to 6.5 with the stock 5500 rpm fuel cut limiter, so there's advantages to spark cut even without launch maps!

I would recommend making yourself familiar with ecuflash and everything before attempting to apply the patch as it could brick your car if done wrong

4b12 N/A Engine almost Done
Im trying to adapt your spark cut to lancer 4b12 gts Na rom
Im already finded the address of the "call to sub"
and where is located your soubroutine is enough free space too
with the same addres you provided for evo "d5ff2"
so the only thing that IDK how to make is the code for call to sub aka "data present"
I understand that the code for that option "data present" makes the call for your soubroutine but i dont know how to make it so i message for your help
here the rom download : https://drive.google.com/file/d/0B8O...ew?usp=sharing

Unless the rom you are using is from another n/a lancer, it is very unlikly the subroutine will function on your car. If you have the stationary revlimiter crossover and normal revlimiter correctly defined I can make a patch for you.
However to answer your question, the last parts of the "data present" is how far is needs to jump to get to the start of the sub routine.
To calculate this, it's (d6000-the address where you're making the call from)/4
The outputed hex is what you put at the end
