had a few minutes to log some data today. very interesting to say the least. this was quick and dirty; i will perform a lot more testing later. first, let's look at the fuel map:



what do we see? first off, at idle and low revs / TPS, the car is doing a great job maintaining roughly 14.7.

next, at WOT, it looks like we average AFR around 12.0. that's a little rich, but not bad. we have to run it against power numbers later at different AFR's to see empirically what works best.

now here is the funny thing: WOT is only 83% throttle on the TPS!! the car is using this to pull fuel and spark maps! also, it's possible the throttle isn't opening all the way. i need to look into this.
