Advice on wiring ShiftX3, ShiftX2 and MegaSquirt
Posted: Sun Mar 17, 2019 11:07 pm
Greetings,
We run RaceCapture MK3 and an Android tablet for display. Previously we were running off of a Chrysler ECU and all inputs to the Race Capture for sensors were coming in via a manually created wiring harness and discrete input wiring. We were also running a ShiftX2 and this was also wired in via the molex harness in the back of RaceCapture and was our only Canbus device.
This year we are converting to using MegaSquirt for our ECU. Our intent is to bring all senors (H20 Temp, Oil Temp, Oil Pressure, Trans Temp, Trans Pressure, RPM, Wideband O2) into MegaSquirt and then pass them to Race Capture via CAN bus. We have also purchased a ShiftX3 - and would ideally like to run this alongside our ShiftX2 for some other display capabilities.
So we're going from having one CAN device (Shift2x) to having three (MegaSquirt, Shift2X, Shift3X.
I'm pretty novice in using CAN, having only used Shift2X. I could use some advice on tackling the wiring initially so I don't make mistakes.
Can all three devices (MegaSquirt, ShiftX2 and ShiftX3, share the same CAN Bus?
Is there an advantage using the Molex Connector versus the RJ45 with splitter(s)?
How do I "address" the ShiftX2 and ShiftX3 so I can use both simultaneously (if this is possible)?
Can I power the RaceCapture and both ShiftX2 and ShiftX3 via input power from MegaSquirt? Can this come in via the RJ45 or should it be run in via the molex?
Any other advice would be greatly appreciated!
Thanks!
Dave
