Rate my tune Audi A6 3.0 TDI BMK 389130

Hello people,

this is my first attempt on modifying a ecu sw for a 6-cyl engine, i had a hard time finding all those torque limiters (gear related, gearbox input limiter)
about the tune:
DW Maps - are untouched, because the values we're from the beginning extremely high.
(i really hope it didn't have a 0.5 factor, judging that the max torque demand in dw was 900 and the engine's stock specific output was 450nm)
Smoke Map - limiter by manifold absolute pressure modified and extendet to 2600mbar
Lambda Maps (4) - extendet to 1300mg/cyc MAF
SOI - extrapolated to 75mg/cyc max iQ
NM to IQ conversion maps- modified
Duration & Rail Pressure - upped from 1600bar to 1650bar (is 1700bar safe? or will the fuel temperature be to high?)
Boost Maps - maximum boost is now 2495mbar
N75 maps - extendet to 65mg/cyc on Regen. and 75mg/cyc on normal, new values generated by extrapolation.

hi, very nice tuning, you had to spend lot of time with remaping this file, but nextime you can extrapolate end of maps (last 2 columns), need not rescaled all maps. you missed one big important map, soi boost limiter, there is after many soi maps and before soi temp limiters. do not make mod before 1250rpm! if you want harder remap, you must touch egt and turbo temperature maps. you missed one tq limiter after main ( find 600 5100 4100 3060 2050 1650 850 ). i leave n75 stock, because little overboost is better for dpf :)

if you want rail 1700bar, you must find rail limiters like 1650, 1680, 1700bar. euro4+ engine have stock rail 1650bar with same injectors.

Thank you Parik for your help, i will see to correcting my mistakes and finding that SOI boost limiter i missed, the DPF will be deleted along with swirl flaps.
Thank you again! :)
