For RPM axis the offset is 0 and not -48. In the rest, all is ok.

like this?

OK changed from "0.25 * X" to "40 * X" the only issue is that I still have all 300kgh in the 320RPM column is that normal?

I have not worked with your particular ECU HW/SW revision earlier but I've never come across (as far as I can remember) this fuction as anything else than 8x8, so in your case the 9x8 is not that common at least.

Regardless, MAF restrictions at sub idle speed is not relevant anyway so...

OK so my attempt then to modify all other values EXCEPT that column was a good idea then.

Probably. If I were you I'd log the actual flow reported (using VCDS) to make sure that the current settings are actually not sufficient and that this is the reason you get a MIL.

After modifying that table no more MAF mil, I was logging VCDS block 002 values higher than was in that table. So now boost is good, cold starts are very lumpy but I still feel like there is more potential for my car so now I am looking at KFMIOP to see if that is influencing the power delivery. According too everything I have read here its the inverse of KFMIRL but now to find it in my file......... I dunno I guess my ecu is one of those difficult ones because not one of the maps seems too fit the 16x11 map I am using as a template  Tongue

I mean, I don't know if there is a technical way to do it, but I open up a closely related damos in WinOLS and copy the offsets over. I just make sure when I'm done it looks correct; text and 2d.

thanks Rob, having a hard time with the RPM axis for this map and I am not 100% sure about the load axis either.
