MAF table changes wont save in TunerPro RT - Third Generation F-Body Message Boards

Here's the situation. 89 IROC 165 MAF (modified less screens and fins)

I'm attempting to modify my MAF tables. I'll go to table 1 and mulitply each by 1.1 (for example) and the values will change but when I save them and pull it back up the top value remains the same as before. I'll go to table 2 multiply each value by 1.1 and go to the top of table 1, change the value to the same as the bottom of table 2 but it still won't save. I then adjusted the scaler table to some higher value and it will then let me save it but when I run the chip it's way out of whack (barely runs and sets SES light) What am I ding wrong? I'm guessing it has someting to do with the scalers but ????

In a previous post redngold stated:

"If you change the MAF tables, you must also change the scalars.

Actually, if you set up your MAF Tables Conversion to be Y/256*X, and have Y be "Other XDF Item Output" and "Choose Reference Item" to be "Maf Table # (each table match to each scalar) Scalar" it will automatically update each table's equation if you change the scalar.

Then, you can FIRST increase the scalars by 10% (mult each by 1.1 in decimal, don't just increase by 10) (except Table 6, it's 255 already), and THEN go into each MAF table and REDUCE the lower flow portions to match up to the PREVIOUS (Lower) MAF TABLE'S HIGHEST VALUE. Blend it properly keeping the curve in there like stock. In table 6, it will hit 255 sooner, though."

I basically understand the second paragraph but the first one has me stumped. Where is the MAF conversion table? Is this in hex or is there a table or something in TunerPro?

My BLM's are really pretty good 128-132ish. (they go lean at tip in, then a little rich- I think I can handle this with AE) I believe I should change the MAF tables/scalers due to the modded MAF. Opinions/suggestions?

EDIT: Ok I've found that if I opposite click the scaler table #x, it brings up the "edit item xdf info" and I then went to the "conversion" tab there is a box called "equation format" and there is an "x" in it. Is this where I put "Y/256*X"? And "arguement type" is "other xdf item output" with "choose referance item" being the "maf table"?

Am I getting warm here?
