Hey guys I don’t know what I’m doing wrong but this is my first time with the aem x series . I’ve done lots of PLX and aem ugo installs with no issues.

CRX
P28 ecu
S300 latest version updated also
I have power from the fuse box and the ground right to the thermostat housing.

White wire off the aem which is analog 0-5 positive to the D14 pin out !

I’ve tried to offset the voltage as much as -2v and it’s still not accurate .

The volts to lamba table
0 5 5
10 20 20

Anyone ?

Do not use D14 as it cannot see the full voltage range. Use D10 instead: http://www.hondata.com/help/smanager/wi ... b=wideband

So issue was on the wideband the brown wire has to be grounded . I will switch over to the D10 as D14 won’t go above 16:1.

Thanks

AEM X-Series wideband use the following data for the Voltage / Air Fuel Conversion:
0.50 Volts = 8.50
2.50 = 13.25
4.50 = 18.00 Air Fuel Ratio
