N/A AFR targets (yes, again)
I've been pondering about this since I was never a 100% happy with the way my AFR targets are setup in MegaTune. I scaled all the tables down to mapvalues used in a non-forced induction motor, but I feel there's more
to improve. Should I really be dipping in the 12.5 AFRs WOT? Not sure if I could lean that out closer to 13 at full load.
Car makes about 140 rwhp on a standalone, exhintake cam swap and dialed-in adjustable camgears.
My idle MAP is between 30-40 kPa, due to altitude and cam overlap, cruising on the highway is usually 70-85 kPa.
Anyone care to take a look at my current target table and the made I cobbled together so far? I attached both tables in the excel file, aswell as a screenshot of the table in MegaTune.
Thanks

Some of the numbers look a bit funny because I was originally using a 12x12 in MLV and then just smooshed it down to an 8x8 in Megatune. Tuned to these targets I get about 33 highway mpg. Might be able to lean out the cruise cells a bit more but I'm pretty happy with it overall. On track with stock horsepower, part throttle is somewhat rare for me. Seems I'm usually either WOT or braking, so I don't need to target ~13:1 until 90+ kPa. Often times in traffic when I accelerate a little from a steady cruise the MAP will get up in the 80s, and it helps with the economy to not have it run so rich in that row.
