Can someone suggest a AFR target table for MSnS-E (fuel only for now) on a 6-port N/A? I've got a wideband in my car and I doubt I'll be able to take a experienced tuner in the car with me. Autotune to the rescue!

to start, you can run 13.2:1 above about 70 kPa, and run around 14:1-14.7:1 everywhere else ... above about 4000-5000 rpms I'd also make it 13.2:1, so you should have a box in the lower left corner of 14-14.7:1 and 13.2:1 everywhere else... later you can lean out your cruise area more ... You can probably go as high as 15.2-15.5:1. I think tofuball went even higher, but I'm not sure it's safe.

Thanks for the input! I guess I should have mentioned that it's a track car. Doh! Cruise isn't particularly important to me until it no longer has to pass emissions to be 'street legal'. I'll put the AFR table in the 'squirt tonight if the wife lets me play with the car.
