Default Rescaled MAF table question

If I have rescaled my MAF table back, will I see lower engine load, mafv, and g/sec flow numbers? I used to see 250g/sec, 4.5mafv, and 5.9 engine load numbers...now that I rescaled my MAF table I see 240g/sec, 4.4mafv, and 5.3 engine load's.

Does that seem correct?

Which way did you scale it? Depending on which way you scale it you can make the stuff go either way.

Decreased voltage, and in one place increased airflow rate. So, basically it takes a higher mafv to reach higher g/sec air flowrate I beleive now. Makes sense to me!

Why did you rescale it? Larger MAF housing? I did one on a 3.5" housing and I had to scale up (massively). The MAFv numbers were lower for several reasons.

Helped bring my target afr and realtime afr real close, within .1 to .2 of each other. For some odd reason the modded stock injectors flowrate is not quite linear I don't think...more of a curve to them, who knows. I just know what I did works though!

If it works, then it works I wasn't really questioning that you did it, rather why you needed to.

Definitely works. Scaled the MAF down -22% to bring the actual AFR's to within .1 of the Map as akira02rex has done. Had to do this becasue upped pressure from the FPR which is a good alternative to replacing injectors.

You will see lower engine load etc so you must rescale you engine load columns as you don't want to be running excessive timing when leaning things out.
