Hi Guys

i exported my maff corrections then clicked save as in rom raider and did this 4 times as messed with smoothing few times.

And upon checking today romraider did not save the changes just made duplicates of the original file even tho i clicked save as i am quite upset as was 4 hours driving is they anyway i can get the corrections from this image i saved?

Imageimageupload

This is all i have as romraider upon clicking logging using Rear Fog switch timed out and i clicked save image before closure.

Cheers
Andy

If no log file was saved of this data (which you can use in the this utility) then just eyeball the % changes between 1.3 - 2.0 VDC and apply them to your scaling.
Or better yet, this method will give the most accurate MAF scaling: viewtopic.php?t=11557

why from 1.3? and am i doing this right as it was -3to-4 at 1.2 i x*0.96 to remove 4% and now its +6 when idling :@ :/?

Oops, that should have been 1.13.

Air temp, pressure (density) has the greatest affect on the lower voltages. If you are within +/- 5% don't touch it. It will wander all over in that range from day to day, that's what it's designed to do.

Was my correction math for removing 4% correct as seems drasticly the other way now but did seem a warmer day of which will add more fuel but am i right saying its better to keep it slightly on the richer side of + and - at the low end for driveability to stop hickups please correct me if i am wrong :)

The math was correct, you are just fighting with the correction algorithm and the atmospheric environment.

I prefer a small negative correction myself.
