Wow thank You for Your tunes!
My car has LPG and K03S with enlarged rotor and 2,5'' decated exhaust with stock downpipe. Everything else is stock, so what file should i flash? Today i made some tests and lambda is going down to 0.76 on full power, so i think its too rich, so i think it cause very bad fuel economy. In town its about 18 l/100 km on benzin and 21-22 on LPG. I had 25 km to work via highway and it took about 15-16 of LPG and that was ok, but now i changed work to one in the town so i got 22 l/100 km and its very bad. I dont need much power now, because its only low speed town ride. What can I do to get this consuption to some about 18 LPG/100 km? If its safe, I can try to flash every file u gave me.
My current tune gives about 1.1 bars on 4th gear at about 4000 RPM, and than decreasing. On lower gears there is no such high boost - 2nd has maybe 0.9 max 3rd something around 1.0 (i have boost gauge). Car makes about 7.3 s/100 km/h at GPS so i think its quite powerful for his age.
I also saw topic

OK i made compare in TunerPro.
Original file u posted is identical with original from topic i linked, about 1700 bytes of differences between Your stage1 files and original, but there is over 400000 bytes (!!!) of differences between original file and my car file (so its 40 % different file) So im done Good night :/

Did you flash this stage 1 tune to your car ? as it seems to be the same numbers everywhere as mine. if so are they safe to use as examples ? it would be a great start.
