BMW E90 320d 163hp 6HP19

Postby Falibor1 » Thu Sep 01, 2022 6:41 pm

I am asking for your opinion on the two files.
BMW E90 320d M47 163hp EDC16C35 6HP19 automatic transmission.
Removed EGR along with exhaust gas cooler.
Swirl flaps in the collector removed.
Removed DPF but catalyst remained in place.
Larger intercooler from the 330d version (about 17% larger than the original one).
Turbo original after regeneration.
Original injectors after regeneration.
Gearbox after XHP Flashtool.

Attached are two tuning files (ver-1 and ver-2) and the original file.

Sorry for my English:)

EGR is made with 3rd party tool. It's enough to remove 2 hysteresis maps eg. C900A and C9070 16x1
NM2IQ is decalibrated, you need to extrapolate the axis.
The same case in at the Duration map, although it s extrap to 95 mm^3 which is about 79-80mg/stroke
In case of boost maps, I wouldn't go above 2700mbar absolute pressure, and never 2700 at 4000rpm

F0C2 and the rest of 3 maps near it doesn't need to be touched, those are some differential pressures, I'm not sure what are them, even with the damos in hands.
Rail is fine i guess, also dpf
so yeah, it'll work but be careful with the turbo and EOI.

Btw for duration you have to extrapolate the rail axis to 1650bar.
950ms at 1600 bar is fine for stock EOI
