MAF tables in TunerPro

Ok, I don't understand this and doing a search didn't clear it up really. There's 6 tables and each one ends and begins in a value equal to the beginning or ending in the next table. For example, my table 1's highest value is 1.46 volts and table 2 starts with 1.46 volts. My question is shouldn't the grams/sec in table 1's 1.46 row match tables 2 grams/sec value at 1.46? Mine do not.

I've split the entries so that they didn't match, and didn't notice a difference, but supposedly you want one table to merge smoothly into the other.

If I understand you last question correctly, No, they will vary depending on wheither your adding or removing fuel.

So let's say that i wanted to change the gram/sec at 1.46 volts, should I mostly be concerned with what table #1 says it is or what table #2 says?

If 1.46 is the last entry on table one, and the first entry on table 2, you'd want to change both.

Yes, that is exactly how it is(1.46 is the last entry on table one and the first entry on table 2) and I thought I should change both as well. But the numbers (grams/sec) on the tables don't match though and that's confusing me. I compared the bin to arap and apyp and they don't match either actually. So what number is the ecm going to go by...table one or table two?

I'm not sure how TunerPro does the math.
But you have the table entry, and scalers to contend with.

Table entry times table scaler divided by 255, gives you the gm/sec..
You might want to write them about how they're doing the math or just do it all in a hex edit.

I didn't notice a difference with them match or separate... but since they are given the same voltage, I would keep the gm/sec the same in each table.
