You don't really interpolate up to 5volts. Once your MAF curve is pretty close, you plot the known range in excel and generate a best fit curve. That curve will have a formula. For MAFvolts above your used range, plug the Volt cell value in the formula at it will spit out a g/s value.

Thanks I read a thread by @rfinkle2; which went into more detail about that here:
Using Excel to dial in your maf curve (meth users, perfectionists, etc.)

I quickly read through it a while back but didn't fully understand it, so I'll definitely read it again

Are you using or planning to use aux fuel?
