Default For you open loop SD guys?

For those of you running open loop SD how consistent is your AFR stay with the environment?

efilive OS3 allows you to touch up VE changes for IAT intake variations. From 0 to 40 dec C I have adjusted mine to alter VE by 2% so its not much.

If you VE is dead on it will track fine over a wide range.

Ok cool because i'm running closed loop SD and trying to tune my PE and i'm chasing it all over the damn place. So i'm thinking i'm gonna run open loop and just tune the AFR I want. Thanks.

I don't notice much variation either...mine is more with humidity than temp, but the temps this time of year vary a good amount.
