Racetech dash 2 and link atom connection

Yes you should have a terminating resistor at the far end of the bus.  

Did race technology program the ECU adapter for the Link ECU?

Is the ecu interface connected like below?

Yes I bought the link interface from rt and followed the above wiring diagram.

 

I will get the resistor fitted then report back! 

 

Will I have to configure all the outputs that I want displayed in pclink? Only would like coolant temp, boost and rpm

Just tested resistance on can h and can l between the 2 and I have 122ohms and 119.8 with probes reversed.

 

This is without the resistor .

A correctly terminated bus will have a resistance of 60ohm, as there is a 120ohm at each end - effectively in parallel.

You dont need to set up anything, you just need the mode set to "Transmit Dash2pro" and it will send the preconfigured stream.

Right update! 

I took the can wires back to ecu re-twisted them neater (they were quite loose) heatshrank the wires to keep them in place, now have no faults.

Have reconnected the aem and no faults (fuelling is correct again now aswell) 

 

As soon as I receive the correct resistors I will fit that then try get the dash working. (Not looking forward to that)

And I can set it to dash2 pro and it'll work OK being a dash 2 (not pro)

You will not be able to use the dash and AEM at the same time with the current setup as the operate at different speeds.  You will have to re-program the ECU adapter to run at 500K later, but that is not easy and you will need a serial adapter etc so I want to make sure you can get just the dash working first.

Well thats great if I knew that I wouldn't of bothered with the rt dash, its already cost best part of £800 and now I know it won't even work without even more work. 

 

Definitely not going to recommend it.

I have a serial to usb adapter here if thats what I need?

Could I connect my aem via another input? An v ? 

Would it work as well as being on the canbus

Update. 

 

I have my aem working on an analogue input now.

And I have racetech connected via canbus, I have no faults at all now.

 

My issue is it is not displaying anything other than rpm.

 

I would like to display, boost, coolant temp and lambda.

Can anyone explain how to do this or a link to a guide please. 

 

Thanks

All of the channels listed below are transmitted to the dash in the DASH2Pro stream.  So since you are receiving RPM that means the data is being sent and the CAN is working - your problem is the configuration at the dash end.  I have little experience with the dash2 so you will have to ask RT how to configure it to receive all channels from the ECU interface.
