Stoich is not "optimum" for power or efficiency. IIRC, it is just optimum for the catalytic converter. The FlashPro won't allow it, but people with other standalone ECU's sometimes tune for 16:1 at a cruise for fuel economy.

 

16:1 only gains 1.25% EGT can be scary on the freeway.

 

I wouldn't run 16:1 at cruise with this motor. 14.5-15.0 is what I'd aim for.

 

The rev limiter is sooo much smoother now. I'm running the Hondata tuned map, with the revised rev limiter, but I lowered it to 8220 RPMs right now.
Thanks for the help gernby

Unfortunately the car threw a CEL yesterday, so I'm taking care of that now. Its the O2 sensor issue that has a TSB out for it.
