Dear Everyone,
I have read everything what I found about using script for LC and NLS.
I made 551C (512kB memory) to work with both LC and NLS (LC blow one huge fireball every few seconds instead of making machine gun sound, don't know why)

However 551D (1024kb memory) which I made works like that:

LC - there is ignition cut, but rev keep rising until red line, doesn't hold steady RPM's
NLS - works like it should

Maybe I can't use 0x384FF0 as a free RAM space? Can anyone check that?
I attach original and modded files,

0x8E800 0x17E00 0x383270


EDIT: Maybe first line of TEMP check can make revs not holding but rising?

I changed FTOMN to 01 on 29f400
On 29f800 i changed from 05 to 00, however it doesn't work like it should. I tried 01, but result is the same.

Maybe first line of the code which is checking tmotlin mess LC ignition cut loop?
