im running a aem ems 1040u and im tuning on the 1040turbo440 start up cal and i notice i cant get any leaner than 8.16 A:F. i check to make sure i got the right sensor selected in the wizard(internal UEGO), which i did, i rechecked the gain and its right. then i get to the o2 sensor cal table and the afr side of the table is scaled from 3.75-8.25 and i cant set any values outside of this range.
how do i change the afr scale on this table??? it cant be that hard i just cant find it anywhere in the user guide or in pro.

 

Before you go blaming the AEMPro O2 configuration ...

Configure -> Units -> AFR Units -> Click AFR Gasoline -> Click Apply -> Click OK

 

ok gasoline was already selected but when i clicked apply it changed the table so idk what happened but thanks for the help.

now the table changed and has the range of the sensor reading from 10-18.5 AFR. is this range correct because i noticed in the aem user guide it shows the range from 8.5-19.5. also i notice in the guide it has two tables for o2 sensors one for o2 sen #1 and one for o2 sen #2. in the table for #1 it shows the sensor range <U>curving</U> up to 5v. and on the table for #2 it shows the range as being <U>linear</U>. now im not running a cat and dont have a seconday o2 sensor, so my questions are; what values should the min/max be for the o2 #1 sensor and should it curve or be linear, also since im not running a second o2 (and neither did the factory) what is the ems seeing/or getting the o2#2 value from and how do i "turn it off"?

again, thanks for the help, joel

 

If you have an AEM UEGO you just run the O2 wizard and select it.

Don't even worry about O2#2.
