a/f

[mazdaspeed32007]

just started to get some readouts from my new a/f and wanted a quick feedback. highway i run on light throttle about a 13-14. on wot i get around a 10.5-11. i have some knowledge on ratios but dont know particulars. is there anything i should do to test out what im reading besides a dyno to get an idea of how my car is doing or did i just basically sum it up right there?
I know a 10-1 or an 11-1 is just fine but i never knew the car ran around a 14-1 on average around town driving.

could you get idle a/f and right where vacuum and boost cross? those are pretty important also. When i street tune my map resolution is rpm/map based and i tune every cell possible to get the smoothest line. if you really have time i would do something in relation to rpm/map to see how its running. 14.1 cruise is pretty good, i usually run my personal car at 14.7-15ish actually. 10:1 is getting on the rich side at WOT, still safe...i would bump all the values to a smooth 11.5. looks like its a safe tune.

Good ? and thanks for advice

sweet. seems like everything is doing what it should and be where it should. just making sure because the more mods i put on the more i get worried rightfully so. thanks for the help. right when they cross i run around a 13 give or take a few on each run. which i didnt think was bad. that from a roll to wot once the turbo starts to spool itself. then of course it goes down down down until the boost is high and the a/f is around 10.5-11. i still havent seen it go below 10.5 or even hit that since the time i posted and ive been driving all weekend all over so it could have been "one of those."

At cruising, light throttle and idle your A/F ratio should be at 14.7 for emissions purposes.

sweet. so far so good. i think i run at a 14.2 at idle. light throttle about the same.
