Safe AFR to get to my Tuner
I just finished my build (moderate NA GSR) and now I just need to get to my tuner which is 30miles away all freeway driving, Im have Hondata S200 but Im not using it cause Its make me run extremely rich, so im running my stock CX ECU which makes me run 12:1 give or take .5 at idle, do you guys think I could get away with that?
if it is 12:1 at idle turn your fuel pressure down a little. just get it so a/f is between 13:1 and 15:1 partial throttle and you will be alright.
While im using the Hondata basemap my wideband(LM1) reads 6:1 then just says too rich while spewing black stuff out the exhaust , I was using RC 310cc Injectors, then I pulled them and installed stock GSR injectors and it still ran rich with Hondata, but halfway decent with my CX ECU, I guess ill have to install my Adjustable FPR.
as long as you can get it atleast into the 13's you will be ok. It's still quite a bit rich for part throttle but its only gonna hurt your gas mileage, not the engine. You could also run a hotter plug to get a more lean mixture.

9:1 is wayyyy to rich. 13:5 will be good for wot, but he shouldnt be going into the high cam anyway. As long as his afr is between 13:7- 14:4 at part throttle, you will be safe.

Actually I turned the fuel pressure down, and got it right where it needed to be and just kept an eye on my wideband all the way there, got it tuned and it runs very well, doesnt burn a drop of oil
