question Dirt2 convertor - balancing roll-axis

[Mertensbart20]

Hello everybody,

I have build a simulator that works with rFactor which can be seen here:

viewtopic.php?f=37&t=335

Now I would like to get it working with Dirt2. Getting the data is no problem, but getting the roll-axis to work properly is a big problem. I know the values for the roll are as follows:

minimum = about 7 900 000
neutral = about 8 984 920
maximum = about 900 000

I set the math setup as shown in printscreen1 and printscreen2 (see attachment). But I get an axis shown in printscreen3 (see attachment). As you can see I can't get values in the lower half. I assume that is because I only have positive values and thus 7 900 000 is than in the middle.

What I need to do is say to the convertor that 8 984 920 is the midde value, but how do I do that? It doesn't seem to work with "Calibration offset of this axis". And I can't seem to just subtract 8 984 920 from the values. Does anyone have a solution for this problem?

Thanks in advance,
Bart

Hello everybody,

After a lot of trial and error I figured it out. You can indeed offset with " "Calibration offset of this axis" but the value you see there is not in the same order as the values from the input.

In my particular case the offset has to be -2147483648 as can be seen in the printscreen below.

Greetings,
