Chiptuning: Tuning Time & Calibration Pressure Impact

Short question for everyone: I have a chip tuning module installed on my 3.0L CDI engine, which modifies the boost pressure and fuel rail pressure (increasing them).

Will this be visible based on the correction values?

I will definitely read it sometime soon and compare it with your values.

Hello,

The corresponding values are determined by the engine control unit at defined rail pressures. If your device "cheats" by reporting an artificially low actual rail pressure to the engine control unit, the actual test pressure will automatically be different, and this can change the timing.

Best regards, Rainer.

The CAPA 3.0 CDI engine with 182,208 km has now been read for the first time. The engine has a chip tuning box installed, which alters the boost pressure and fuel rail pressure. I don't know if this has an influence on the NMK (likely referring to a specific system or component).

However, as I already wrote, this has an influence, and the values are not usable.
