Alfa 159 2.4 JTDm popcorn not working out

Postby d.dimitrov » Wed Jan 15, 2020 8:07 pm

Hi,

I am trying to do a popcorn and launch control for my alfa. I've read through like 1000 thread already and have come to the conclusion that the popcorn should be done with the TL map. I did that in like 10 different scenarios and none of them worked. There is a "pop" of sorts, but nothing like in the videos I've seen.
I am shooting for something like this: https://www.youtube.com/watch?v=9AS32Zy5bTA
But what I've ended up with is something like this (only a bit slower): https://www.youtube.com/watch?v=ph-9s6RvJ2Y

I am uploading here the original file and the latest file modified by me and a csv with all the maps that I've found so far. It would be great if someone can point out what I'm doing wrong and how to fix it.
my-alfa.ori

Popcorn Limiter Test 16.bin

maps.zip


Also about the launch control... From what I've found so far most VAG cars have a "launch" map, but there is no such thing for my alfa, or if there is, I was not able to find it. The best advice I've found so far online is this:
"find gearxspeed ratio, then make first gear 0kmh, and copy values from fist to 2nd , ect .. or something like that then the firs gear TL will be actually neutral TL map"
However I am not able to find "gearxspeed" map. I do have all TL maps from 1th to 6th gear though. So... any help here would be also appreciated.

I read that people use Gearbx_trqDriveOffF_CUR (damos) to make launch control. they just put 0 on rpm they dont want engine to go higher then.

For popcorn

Search for 5400 25 @ 16 bit
Make 5400 > 4600-4800 (what rpm you want)
