I hooked up my wideband O2 last night. (the tech edge kit)
I noticed I'm pretty spot on (14.6-14.8) most of the time... Except when I let off the gas, it spikes to 20:1+...
Is that normal?
Also, at WOT I'm around 12.2:1 - 13:1 Can I lean this out a bit?
What's a safe WOT A/F ratio?

Yes you can adjust it, but its easier with a Standalone. You're best bet is to log a bunch of runs. The parameters to look at are A/F, Engine Speed, Engine RPM, Knock and Throttle Position. Then you can review exactly what your car is doing, and adjust the fuel table.

As far as the 18+ A/F on deaccelleration...I get the same thing. I haven't looked at the Accel/Deccel settings yet of my AEM EMS, but I plan too.

if ur stock, honda does a good job managing fuel. and when u let off the gas, its normal to spike to 20:1..because u don't need much fuel to just coast

Everything you noticed is completely normal. Under no-load conditions the engine runs extrememly lean by design.

Sweet... Thank you!

How about a safe A/F for an NA setup?
...under load.
