Since this is the first topic in the calibration section, I decided to put a bit more effort into it and do everything properly.

First of all, I want to point out that all changes were made directly on the original file you attached. This is not some generic or ready-made mod taken from somewhere else.

The first file is a nice, smooth Stage 1. Based on my calculations, the expected output should be somewhere around 310 hp / 650 Nm. Of course, the actual result will depend heavily on the condition of the engine, fuel system, and all the other related components — that needs to be clearly understood.

The second file is Stage 2. Power-wise, it already goes a little beyond what I would normally consider Stage 1, so I would describe it as a mild Stage 2. Expected output should be around 330 hp / 700 Nm.

What I changed regarding the oil pump:

In the stock calibration, the oil pump switched to the high-pressure stage above 2500 rpm, or when injected fuel quantity exceeded 39 mg/stroke.

In the modified calibration, I lowered the RPM threshold from 2500 rpm to 500 rpm, while keeping the factory 100 rpm hysteresis unchanged. This means it switches back to the lower stage only at roughly 400 rpm or below.

As a result, once the engine is started, the oil pump switches to the high-pressure stage almost immediately and then stays there practically all the time.

The oil pump fix is included in both files.

I’m really looking forward to seeing how everything performs once you test it and hearing your feedback, because I genuinely put a lot of work into these calibrations. This is an individual calibration I made specifically from your original file, not a ready-made mod that was simply copied over.

Thank's a lot, we will try it the next couple of days and report the results here.
