I used 0.03913*x+14 to get it right. And I used the white (signal) cable from the rear oxygen sensor plug since it was replaced by the WB sensor... A lot easier...

Can someone explain the formula, where did the values come from, it is totally not working for me, I tried from 9-14. It will read close sometimes but easily drifts away in more then 1 afr difference.

After some runs I have come to the conclusion that this formula isn't right at all. It drifts away with more than 1 AFR above 14 AFR and below 13 AFR... Where did this formula came from?

I dont remember were I got the formula , but it was from a well known source and it works great for me.
X187 If you think its wrong , what is the right formula?
Neilm for you there is probably no input for it since you have an evo 7, you will have to figure out something else that you are not using like fuel temperature sensor , and you will have to figure out what the address for it is, and configure it into your evoscan. Another option for you might be to reflash an evo 8 rom onto your computer , or just replace your computer with an evo 8 ecu.

also.. do i have to cut it close to the ecu or can i cut it where it ends at the plug which is under the passenger seat.. i removed the rear o2 already so i have the plug pulled out of the carpet for easy access.. also i noticed at the plug end the almond color wire which is pin 75 at the ecu end seems to join a black wire and go into a thick blue wire which is then run under the carpet towards the ecu...weird? thanks for all the help!

I removed my rear o2 a while ago..your saying to use the white wire that goes into the plug thats under the passenger seat correct? if so i looked into doing that instead of cutting so close to the ecu but i noticed the white wire at the plug end joins the black wire then runs under the carpet to the ecu where they branch off again to go to separate ecu pins..so its deffinatly possible to use the white wire close to the plug instead of at the ecu?
