I found I had to reduce the numbers in my table to get everything to match up.

I did everything in uint8 numbers and my actual values at the low frequency range was like 100 where factory was ~115. The numbers came out pretty rough and bounced around alot, but so do the factory values so who knows.

cool beans...something new to play with.

Any luck with this and tuning idle? I still get the occasional Hz spike at idle. Maybe this can smooth it a bit?

This won't smooth your MAF frequency out at all.

I think listing it as a smoothing table is a bad call as it seems to be more of a scalar and has nothing to do with smoothing.
