VW Golf IV 2003 1.9 TDI AXR 74kw

Postby nodna » Sun Aug 26, 2018 12:08 pm


tried to adjust my maps a bit.
- Driver Wish
- Smoke Limiter
- Torque Limiter
- Boost Limiter
- Boost Target

Do I run too lean/rich?
Will my turbo blow some day?

Smoke Limiter: How can I find what mg/stroke my engine gets? Wil a better air intake filter change the amount?
N57, SOI, Duration: How can I find out where the maps have bottlenecks?
SOI, Duration: How can I calculate the IQ for the SOI? Don't want to run too lean.

Thank you,

If we get AFR 17 with no smoke, then in smoke limiter we need to divide x axis by 17, so last column 1000mg/17=~59mg.
If you will push torque limiter to 59mg will gain more power, theoretically, cause stock PDs cant probably give more than 60mg.
turbo safe.
pretty tune.

Do u got eeprom from this ecu?
