RomRaider

While I was looking at AVCS tables for my car (2007 EDM 3.0 Spec.B 6MT, D2UH001L.xml) I noticed that the angle values were quite low compared to some other ROMs of a similar engine (same year JDM D2PH41Q, for example). And that wasn't just a 'few degrees' low - where the other ROM has a value of 50°, mine shown 13.89° of cam advance...

It's also weird that in 'Table -> Compare' menu, the 'Compare to table' option was not available, even though I had both ROM's open and was looking at the same tables.

So I had a look at definitions and I found that there are actually several sets of definitions for Intake Cam Advance Angle in the XML, all having slightly different names:

• "Intake Cam Advance Angle (AVCS)"
• "Intake Cam Advance Angle A (AVCS)"
• "Intake Cam Advance Angle B (AVCS)"
• "Intake Cam Advance Angle Cruise (AVCS)"
• "Intake Cam Advance Angle Non-Cruise (AVCS)"
• "Intake Cam Advance Angle Cruise (AVCS) "
• "Intake Cam Advance Angle Non-Cruise (AVCS) "

Notice the trailing space in the last two - it's important.

They're all fairly similar (besides obvious different descriptions for A / B / Cruise / Non-Cruise), weirdly they all have 14x18 size even though they show up different sizes in RomRaider.

But crucially, one set has a different 'scaling expression':






And judging by the D2UH001L definition, the one is used for my ROM is the odd one - notice the trailing space:



while the other ROM(s) use the other definition - no trailing space:



So which one is the correct one for my car? Does the cam advance actually go up to 50° or is the max. 13.89° the realistic one?

That scaling is correct - the scaling can be different across the various years' models.

From the rom:


And yes, it does go up to 50 in the stock calibration:

I find it a bit weird that my 2007 3.0 Spec.B would have so wildly different AVCS tables than a JDM 2007 3.0 Spec.B.

Left is mine, right is the JDM one:

Oh, I just found out how to display raw values - these are the same between both ROMs:
