Rx7 s6 pnp can expander issue


Recommended Posts

This device is a serial to CAN converter, it connects to the ecu master ecu via rs232.   It is used for the ECU master ecus that don’t have a built in CAN port.  You don’t need it as the Link ecu has a built in CAN port.  What are you trying to achieve?

Would it just be a case of re pinning the can wires into the rs pins ?

No, its not going to work at all.  It will only communicate to an ECU Master ECU in their own proprietary protocol.

I’m trying to gain analong inputs for egt sensors.

EGT's only output a millivolt signal so you would be better to use a CAN bus EGT amp.  The ECU master one works well and is relatively cheap.  If you already have an analog EGT amp and just want to input analog 0-5V via CAN bus then this would be the suggestion:  https://www.autosportlabs.com/product/analogx-4-channel-analog-to-can-interface/
