Question to the self-mapper among us: AFR target ?

[Uzelac]

Hi

What AFR target's do you recommend ?
I've finally get a hold of wideband controller and yesterday started to "play" with it. I'm using PGM-FI so i use Crome and Ostrich 2.0 for real-time mapping and logging and it works just great.

Now i should decide, what AFR's to target ?

There are plenty of examples on web, but I'm curious if 4AGE specific, does someone have dyno experience and knowledge what AFR is best in regards to power output, safety, consumption ... etc.

Thanks

The standard ecu set up is around 12.5 afr under load on a stock engine.

Isn't that a little bit too much ?

Maybe not.
As much as i can see here, everybody is targeting ~12 :

I'll try to adjust WOT around 12 also, but i've got no idea what to do with low to medium TPS.

12 AFR is a great target!...















(for 8lbs of boost)

From reading that post I still think the general idea is to go for 13 AFR.

It looks i'll have to try, let say 12.5, 12.75 and 13...

in my opinion 13 is a bit lean..

12.5 should be nice

take 12.75 as a max.

I know that a stock ECU runs the engine rich as hell. This is to ensure that it will last longer.

And what about 20-70% of TPS ?

13 for 70% and 14 for 20% ?
