Hey, im learning to tune maps and i need help!
My audi a6 c5 2.4 v6 has 2 timing maps, second one has little bit more advance at 60 and 68 load.
Why there is 2 timing maps? If i want put more advance do i need change parametres in both maps?
Also want to ask is there any point to put more advance under 60 load (30, 38, 45, 53, 60 load) like 1500rpm - 4000rpm? Im trying to get little bit more response and better fuel economy.
Is there anything else what to change, i did change lambda map (picture) and then timing map/maps?

If there are only two, then one is for inlet cam fully retarded and other fully advanced. To make sure you need to change both.

You can't go leaner than lambda 1, so your changes do nothing.
Learn how to make screenshots instead of taking photos with your phone.
Adding timing randomly is also a waste of time, you need to log... and on part load you need a dyno to find MBT.
TBH doing anything on that engine is a waste of time. Sell the car and buy a 1.8T if you want to tune anything.

Upload the original file and Ill have a look, Ive done 2.7t turbo setups on 2.8l 30v with a compression dropping head gasket and quite a few supercharger setups so I have a bit of time invested in those software versions. Also in stock form as Prj said, its a waste of tuning a stock engine, and its not worth renting dyno time to gain 8 horsepower peak power. At least that is what I have seen with stock exhaust manifolds gutted down pipes and stock exhaust on (91 usa) 95 euro octane. |

Sorry for pics from phone, i have done logs and tried adding advance, but seems cant add much. Is that sure if i put lambda over 1 it does not do anything? There is only lambda map, no afr map. Well im not looking for extra power, only better fuel economy if that is possible. I use 98 euro octane in my car. Prj: in next year im thinking change to vw/audi 1.8t  and just want learn these things so its easier in next car, of coz its alot different in turbo cars. |

If you want the car to "feel faster" react quicker to input other maps will need to modified for the desired result The reason the file I modified looks different then others is because i didn't just make mindless changes using some cracked version of ecm titanium like I would be willing to wager others did. Again, if you don't want to use the file, don't. |

Well im going to try tomorrow I did load your software and just want to ask about lambda voltages, they are at idle 0.055v and normal city driving both are about 0.055V-0.065V, all time like under 2000rpm what i did check from logs. (Normal rpm at city driving is about 1250rpm) At part throttle accelerating it did feel like motor is not getting enought fuel, dont know is it because automatic (high gear).. also here is winter and outside temp was -15c What map keeps voltage that low? Would want to try little bit more richer |

Could someone help to get my 2.4 v6 audi a6, is it possible to make it little bit leaner?
Im just thinking there is TABGBTS value: -46,29 c??
Do i need Set KFFDLBTS all to 0, KFLBTS all 1 but last ones? What about LAMFA and USR?
Is it possible to change o2 sensor to any voltage? Nameless did do changes for and USR is set to 0.056, i tried to change that like 0.080 and my car didnt start very good and at idle it almost shut down so i think it went too lean?
