Having problem with Wideband AEM!! AFR wont calibrate!!!

[greencivic_0789]

Tuning 95 civic ex with obd1 H22a jdm.

im having a problem, when i try to make my hondata read the same as the aem wideband gauge i cant get it to go below 12.24 afr. It will say 10.1 on the aem wideband gauge and it will say 12.24 on hondata. im using smanager 1.4.8 by the way. when i try to change the voltage offset it never changes but when im running under 12.24 the voltage offset actually works so im thinking the 0-5v isnt working right, im thinking, its only running like 0-3v or something. i have my 0-5v white wire from my aem ugeo 6-1 wideband to pin d10 ELD and i have that selected under closed loop perameter. im running a jdm p72 obd1 ecu with hondata s300 i checked and couldnt find the r136-r138 capacitors in the ecu, so im thinking that jdm ecu's dont have them? thats all i have to say about that. so if anyone would have any info on how to make this work right that would be awsome thanks[/size]

Post your calibration and a datalog showing the problem

Try using B6 for your wideband input source

when you turn key to ON, what is the AEM WB show...P0,P1,P2,P3 or P4?

Hi

is the sensor fitted in the stock location?

There is a voltage offset of about 0.02 with the aem wideband, I think 2.46v = 14.7 the actual figure is shown in the manual that comes with it for the conversion table

It might be worth measuring the voltage coming from the sensor
