Good day mates.

I would like to give you my mod to check and evenually share.

Thats light mod for 2006 Skoda Octavia 1.9 TDI AXR running on stock set up.
Its safe, smokeless, running good.

Main idea was to gain a little bit of performance with less fuel consumption at low loads.

So:

Engine code AXR @stock setup.
Part number 038 906 019 PB on 019 KJ hardware - yep, these are interchangable.

From the beginning:

:arrow: DW has reduced IQ at 45, 65, 85 % of TPS. Just to eco driving. I have really heavy foot.

:arrow: Start IQ increment just to start easier

:arrow: Idle RPM increment just to warm it up faster

:arrow: TQ modelled for safe DM Flywheel , without any kick in back.

:arrow: Smoke adjusted to AFR17. One change in last column of MAF just for presision.

:arrow: Boost target map lowered under low rpm for economy. Pushed to 2175 mbar absolute, SVBL untouched at 2350.

:arrow: N75 adjusted at low rpm for fuel economy, and reduce overboosting at 2000-2500 rpms, specifically for my car.

:arrow: SOI at 76 and 89 degrees advanced at low rpms for fuel economy.

:arrow: EGR not disabled, adjusted for economy.


I have no dyno so i cannot measure my mod.
There is no kick in the back at acceleration, but car is different, much faster and lighter.
According to economy i was able to reach 3.5 - 4.3 l/100km @ 90km/h at flat road. Much less than in the beginning.

Please rate.
Any opinion will be considered.
Only thing that is limiting me is the smoke limit, but i dont want to have black cloud behind.

I have a good way to mod AXR's 019PB, so feel free to ask. There was a lot of bricked ecu's...


Have a good day!
