So, a first edition of a pdf has been scribbled down.. consisting of my notes on how to implement setzis v2 function of anti-lag & NLS.. i would love for someone to try this and report back in this thread with feedback and results. The NLS cuts spark under given "conditions" when the clutch is pressed. (acclPedl threshold, time, rpm etc) When conditions are correctly set this function makes the gearbox WOT-shift like butter..  just an advice.. this anti-lag is cutting spark, so unburnt fuel will enter the exhaust manifold and "explode" in the turbine, making the EGTs skyrocket and the turbo spool in an instant.. while this is somewhat effective to build boost on the line, it poses a great threat to an OEM catalytic converter. In my own function ive implemented throttle control and fuel-cut to keep things "under control", but this function is not yet position independent and will require some real work before it is finished and later released.. so in the meanwhile, enjoy this nice implementation by setzi, and try not to kill the drivetrain.. if possible..  |

It's easy to see how much time you've put in here. It's also a good intro to general patching. Nice one - have some Karma.

Thank you! I will be working on this over the coming days and I'll report back with my feedback. You really spent a considerable amount of time on this and it's greatly appreciated.

Great work. Thanks for taking the time to write this up. Many people underestimate the amount of time it takes to write an informative document. If you send me your FTDI info, I'll send you a NefMoto premium features license. |

That is just brilliant!
Thank you and setzi for your time and for sharing such detailed info!!!
I would definitely try this and i ll report back (probably not in few days but i ll report for sure).

thanks for the positive response guys, lets hope someone actually manages to implement the functions following my quick "guide"  i wasnt really sure on which level of detail i should describe this first relatively "simple" method.. but i tried to stick to a level that most people, who have enough knowledge to make their own stage 1 tune, should be able to comprehend, since this could be a nice addition and perhaps the next small step forward in evolving their tune.. Tony: let me get back to you on that FTDI info, i have a 232RT based cable in the car i think, which should be compatible, and i would love for the flashing to be quicker.. since i do alot of reaserching based on the trial'n'error principle  come on ppl, lets see who is the first one to verify that this method works |

WOW. Awesome write up! Really gives a lot of information to process. It's really nice to see it dissected like that! Really did a thorough job.

Will this work with a 400bb ECU? I'm working on a 4B0 906 019 P 400bb 2000 Audi A4 1.8t Manual.
What's the reason 8 is added to the address when calling the new function?
I flashed a file already with the code implemented but there was no launch control limiter.
Seriously thanks for taking the time to write this up!

I'm working on a mild version that also cuts injection in the same way as the soft AL. I wrote a function that set bit B_nmaxd and therefore makes minmx_w = 0, looks promising but I had little time to test before the intense pressure separate a clamped union in the exhaust. Tomorrow I'm going to reassemble the joint with exhaust glue and try again. Here is the fuel cut function code: function_AL_NLS_fuel_cut:
jnb B_kuppl, ret_AL_NLS_FCut
mov r4, vfil_w
exts #(PARAM_SEG), #1
mov r5, SPEED_THRESHOLD
cmp r4, r5
jmpr cc_UGE, ret_AL_NLS_FCut
;movb rl4, tsrldyn
;jmpr cc_NZ, ret_AL_NLS_FCut
mov r4, pvdks_w
exts #(PARAM_SEG), #1
mov r5, BOOST_LIMIT
cmp r4, r5
jmpr cc_ULE, ret_AL_NLS_FCut
bset B_nmaxd
ret_AL_NLS_FCut:
mov r4, ngfil_w
rets |

Im thinking the calls instruction use the full address to a location in the ecu ROM, which starts at 0x800000, but when reading the ROM with the nefmoto program, that 0x800000 becomes the first address, 0x00000, in our .bin file, correct me if im wrong =) i think you can make this function work on a 400BB ecu, but you will have to read up on some addresses.. BUT, im not sure that an ecu using the 400BB memory would have the later ignitioncoil driver.. which could result in blown coils, drivers or fuse.. = BAD.. someone will have to test this. ArgDub: Nice, if youve read my previous posts here youll notice im also looking at this with fuel-cut and throttle control to keep things smooth while building boost.. ive got it running pretty nice atm.. im also thinking we could alter setzis v2 function to cut fuel instead of spark to make a "soft version" that can be implemented just the same way as this spark-cut version.. for those using OEM catalytic converters in their daily drivers etc.. |

is it too much to ask the original file plus the original with nls and flat shift? It should be more helpful this way.

Although injection cut makes it less violent, it is not yet even close to anything you can use often without breaking something. I think we also need to reduce air charge.
sn00k: Nice, could you explain from where you are linking the throttle control?
About flash, it isn't mapped to a particular address because it uses BUSCON0, so you can access flash at 0x200000 for example.
