AngelPowy Posted May 4, 2018 Report Share Posted May 4, 2018 Hi, I was asking myself if it’s possible to wire an aem wideband gauge to G4+ link extreme using RS-232? The fact is that the aem gauge I have only use 1 wire output signal to efi and the engine ground. So the ground can float as the ECU does not use engine ground to compare with analog input. I think as rs-232 is a bit transfer protocol it may be more reliable and give the ECU better AFR reading. I know that link extreme can be wire to use rs-232 so I do think that it’s doable. Does somebody already tried it? Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 4, 2018 Report Share Posted May 4, 2018 No our ECUs dont have a configurable serial input. Analog or CAN are the only options you have for wideband. Edit: I guess you could build a very basic serial to CAN converter if you were interested enough, but it would probably be easier to sell it and upgrade to a slightly newer AEM that has CAN bus.
