Hello, so let me first say, first time building a turbo car here, first standalone, and first time ever even hearing of CAN systems. I’ve done a decent amount of research, good amount of thread hunting here, but haven’t found the answer.
Car is a 1995 bmw m3 s50b30 us spec. I have a plug and play g4+ ecu. Car is obd1 so I’m not sure if it has a CAN system?
I have AEM x-series wideband, boost, and CAN guage, and I’m trying to tie the wideband and boost guage into the ecu CAN system, but The manual doesn’t show any CAN inputs.
I’ve learned the “bus” theory, so would buying the CAN expansion harness and then tieing the gauges into the CAN +/- wires? Or do they need to go to inputs? I know the boost and wideband CAN wires are optional and don’t need to go to the ecu, so not the end of the world if I can’t integrate them with the ecu, but I’d really like to figure this CANBUS thing out.
I would like to use the AEMNET CAN guage to look at water temps and oil temps and pressure, but I do not know if my cars factory sensors will communicate with the CAN out of the ecu to the guage.
I haven’t hooked the ecu up to power yet because I’m lost on wiring all of this stuff up. I hope I don’t sound COMPLETELY new, but like I said I’m new here.
Thank you for any help,
