AFR Tuning - Here is my partial map
 
I started out with a baseline, generic injector opening time/AFR map and did some runs yesterday on the track with the datalogger running.

Based on the datalogs I picked around 30 datapoints where I had reasonable confidence that I was close or knew how to adjust the opening time to get the AFR dialed into those points. Those points are shaded in green on the image below.

I then interpolated the points in between. Those are not shaded. You'll notice I had limited data below 2000rpm (it doesn't spend much time there anyway) and nothing over 4500 (I am still breaking in the engine.

Here's a "surface map" chart of that data.

Some car details:
3.0L
RoW heads smoothed to match 3.2 aluminum intake
K&N filter (for a Dieselmax, the BIG BOY!)
DR20 cams
JE 11:1 pistons
Twin-plugged
Bursch headers into flowmaster dual-in/dual-out
Fuel pressure is around 40psi
26# Accel injectors

Hope that helps, would appreciate anyone else's posting of their maps too...
