Tutorial: How to scale your MAF [pics]
Sup guys I have a quetion for ya so I just did a major uprade to my car which involved turboing my na car as well as upgrading the injectors and fuel pump. My questions is how do I know which to scale first my injectors or my maf? Is there something I can log that will tell me which to adjust first?
I've changed user level to developer and still nothing. Can U tell how can I update my XML files ?

Keep in mind there is a ton of different ROMs for the EVO and many of them are not fully supported. It may require you to re-flash to a different ROM to be able to use all of the tables.
Post your ROM ID and we can go from there.
Excel Displays the numbers as thier actual value (as opposed to ECUFlash's) and I don't feel like correcting it so:

18.87 145

If so, you can use unit16 in place of Aiflow Hz to get those values. If thats not what you mean, then I'm definitley confused.
Yeah, You're right. I don't understood this at first. Sorry
PS. DO You remember settings in "ROM to display" and "DISPLAY to rom" places ? I had already somethin' like 6.2x, but I cannot remeber

Thanks a lot. This forum knows everything 
And one more thing: Can anyone tell me, where could I found the MAF Scaling table .xml patch for 88590015 ? Is the table "MAF scaling" in this ROM the same that "AirFlow/HZ RAW scaling" ?
