SO i tryed to search could not find a good answer what is a good afr in boost i generly hold 12.8 then when vtec engage i get13.1-13.3 which is still showing up rich on the widband? is this safe my motor is a b16 this is about 9-10 psi o yea this is on a basemap but my first time on the track i refuse to run a shitty time. Crome owns me!!!!!!!!!!

 

you could lean it out alittle in the higher rpms but if you really dont know what you doing its pretty good where its at. normally 12:1 is what they say for forced apps but it all depends on the setup and conditions. SO BE CAREFULL

 

isnt 14.7 the ideal afr?

 

seems pretty lean to me... you might want to richen a/f in boost around 12:1 to high 11s to be safe, especially if your noobie to tuning. Whats timing at as well?

 

yea, go ahead and do that to a boosted setup.

 

i have no idea its xenocron basemap when i logged it the highst time i saw was 27 deg i belive

 

guess you missed the question mark at the end dipshit.

 

You need more fuel with more air, but yea stoich for most naturally aspirated engines is 14.7. When you have hot pressurized air and no fuel you get crazy crazy lean burn exploshun deathkibab.

 

14.7 is stoich. Turbo's run hotter so they have to runner richer.

So is there a Turbo Stoich?
