Hi,

I have a stage 4 by buschur and i have their settings for SAFC II for the specific stage 4.
My question is, i have a water injection running 50/50 meth and im running 91 oct.
Should the settings be any different than what buschur gave me?
They assume that with that settings, i would be running on a 116 oct, however there is no way i can be doing that.
Also i have a 10.5 hotside and i think theirs are the stock 9.8.

The reason i ask is that i dont know if i want to be buying the wideband o2. it cost a lot. Would there be another way to get the safc 2 tuned if i bring it to a shop for a dyno? I dont think so but what the hell do i know..

Last but not least, are you suppose to be able to see afl on the channel?

Your response would be greatly appreciated.

Thanks.

 

Take it a dyno and have them run AFR when they run your car. Other then that a wide will be needed.
