Wideband cooked??....
Hi all.
Got an annoying problem with my AEM wideband. Was working perfectly on my old Ecu. Then bought a 2nd hand MegaSquirt, and wired it all up. On TunerStudio the wideband gauge would flicker from where it should be up to max....faster when revved.
Took apart the Ecu and found a sloppy bit of soldering bridging the 12v coil circuit with the 5v wideband input circuit.
Corrected that but now the AEM doesn't output any live down the 5v output channel. I'm guessing it didn't like 12v shoved into it!! Took the unit apart and can't see anything melted etc... Didn't know if anyone has any suggestions of where to look for circuit diagrams, or a repairer for the AEM units.
AEM sell the controller/gauge for over £120 so was hoping to see a melted resistor or something!! Lol.
Thanks
Matt
