Optimum A/F ratio target points for tunning
 

Hopefully getting a cobb AP shorlty, was curious as to what are the optimum target AF i should set. Not sure if this is how it works, my tunning knowledge is fair at best. My only concern is power, do not care about mpg what so ever. I f i didnt make sense, forgive me.....thnx

Just wondering,

Why you wanna support Cobb since they are not supporting us!! leave them alone!

lol, well from what i understand they are just not writing tunes for us anymore. But as long as you have tuner, they can write it for you...i think thats it in a nut shell

personally i would go with osrius. :twocents:

Just got the Uprev this week.
Do not have a tune for it.
Jnaut send me your tune for my car.
All i need is the tune for the engine as mines a 7 AT all i have in it now is the stock curve.
Still learning how to use it as I can only load tunes and waiting for Sam to send me the tunner program.
I may put the Cobb back on the car for the weekend at the track.

I may just do this! What are your AF ratio, by how much did you advance timming?

12:7.1 about optimum for the VQ on WOT,, little richer up top, I have run leaner with out any knock but could not monitor EGT's etc. TBH, I prefer to tune to rich power rather then lean.

i personally have mine at 12.0 to 12.1 @wot. My car made to most at this afr , not leaner

Thats the thing jnaut, you can have two cars with the same mods and each will produce different results of the same tune, big reason why I dont run OTS maps.
When your fuel is right the difference in feel is amazing...
