removed R16 & R18 now AFR doesn't read

Post by cityofcaterpillars »

So my Buddy got a Del Sol the other day with an AEM Uego wideband installed.  I'm hooking up Hondata S300 and I'm having some trouble getting the wideband wired into the ecu.  I know the white wire on the AEM is the analog 0-5V so I sliced into that and wired it to D10.  Hondata showed the AFR but it was way off.  like more than could be adjusted with the voltage offset.  I opened the ECU and R16 and R18 were still connected so I removed them.  Now  Hondata wont read it at all.  It just stays showing 20:1.  The gauge still reads right but I can't do any data logging.

Has anyone ever ran into this problem or have any suggestions?  I've only ever used innovative widebands so the AEM is a little foreign to me.

What is the voltage when measured with a multimeter from the wideband.

Why have you removed those 2 resistors?
