G4+ PlugIn - CAN to PCB Pinout

[iecku.tavea racing]

Hey

I am trying to connect an AIM MXS to a Link G4+ PlugIn via CAN/PCB Cable. I used these instruction from AIM (http://www.aim-sportline.com/download/ecu/racing/LinkG4_CANBase_102_eng.pdf), but i doesn´t work. Is there a difference in wiring to the PCB cable?

I set transmit rate to 10Hz and format to normal. The Aim is setup with the 1mpbs settings they provide.

Do i need to adjust anything on the streams page?

Can i see the Aim MXS on the devices page even when there is a problem in the configuration?

The CAN-PCB cable will need to be plugged into the 'CAN/RS232' or 'CAN 2' socket on the bottom (bigger) board of the ECU. In the ECUs CAN Setup you need to select the CAN module you are wired to (CAN  1 or CAN 2).

Nothing needs to be done on the streams tab. The CAN-PCB cable connector pinout matches the image shown in the Aim pdf file you linked to. Try the transmit frequency on 20 Hz or higher.

Here is a document showing how to set this all up. If the communication still does not work please upload your ECUs base-map.

Hey Scott

I checked the wiring once again. It is right to the documents. I attached the last pcl before startup.

I also attached the configuration of the AIM MXS in Racestudio 3. Perhaps it helps you.

Looking at the Aim setup file you have selected the '500K' ECU stream. So you will want to set the Aim to the 'CAN Bus Base LCC' ECU stream instead.

Looking at the ECU's CAN setup you have CAN module 1 set to 500 kbit/s, and CAN module 2 set to 1Mbit/s. Which one do you have the Aim wired to? Whichever one you have the aim wired to should be set to 1Mbit/s (to match how the dash will be setup), and the other CAN module should be turned off.

Hey Scott

Back again me. The problem is still not solved. I tried the 500kbit setting the last time cause the 1mbit didnt work. I tried different settings in the aim, the link and also the wiring. I will not work.

I found there is a "K-Line ECU output" on the aim dash directly beneath the can1+ and can1-. Do you know what this is?

I can not see any setup problems in your latest files. One way you can test the ECUs CAN bus modules is to wire CAN 1 H to CAN 2 H, and CAN 1 L to CAN 2 L. Do not have anything else connected to the CAN bus. You can then send something out of CAN module 1, and receive it back into the ECU as something else on CAN Module 2. If this is successful it shows that CAN Module 1 and 2 are working well.

I have modified your latest base-map to do this test. You will need to load the attached base-map into your ECU, and wire the CAN bus modules as described above. You will then need to setup a Digital gauge in PCLink like I have in the following video. CAN TC Cyl 1 should show the engine speed, so start the engine up and check this. If it is working then CAN 1 is sending the engine speed out on 'Generic Dash' CAN stream and CAN 2 is receiving it back as 'CAN TC Cyl 1'.

Hey Scott

Just for confirmation...the white an the green cable on the CAN-PCB cable are for CAN-Bus?

[Simon]

Yes correct.

White is CAN H and the Green is CAN L

FYI

I had a long chat with AIM Germany back in february. They told me, that AIM is currently not supporting the canbus of the link ecu. So i just wired it up for Rx/Tx as the support told it to me and it directly worked fine.

They told me, that AIM is currently not supporting the canbus of the link ecu. 

Thanks iecku, I'll get in contact with them and clear this up.

Was this resolved?

Can you share the recommended settings please, I'm about to install my plug & play with the AIM MXS and any help to ease the frustrations now would be greatly appreciated
