F430Jonesey Posted November 27, 2017 Report Share Posted November 27, 2017 Hi, I have installed an Aim MXL2 data dash into my evo VIII that has a G4+ ecu. I bought the dedicated cable to connect them but the dash is not reading any data from the ecu. Any help on how to overcome my current frustration will be very much appreciated. Thanks JJ Quote Link to comment Share on other sites More sharing options...
Simon Posted November 28, 2017 Report Share Posted November 28, 2017 First step will be to head to the PC link tuning software help file then search AIM Navigation: G4+ ECU Tuning Functions > CAN > Device Specific CAN Information At the bottom of this page is specific info on connecting the AIM Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted December 3, 2017 Author Report Share Posted December 3, 2017 Hi Simon, I have spent several hours on this today without much success. 1. Connection - I am using a CANDASH cable from the ecu with the CAN H cable (white) connected to the Aim CAN + cable and the CAN L cable (green) connected to the Aim CAN - cable. The other 3 cable ends (brown, yellow, grey) are insulated. 2. ECU - I set the ecu CAN Setup in PCLink as follows and saved using F4; CAN Module - CAN 1 Mode - User Defined Bit Rate - 1 Mbit/s OBD - OFF Date - Channel 1 ; Transmit Generic Dash Mode - Transmit Generic Dash Transmit Rate - 20 Hz CAN ID - 1000 Format - Normal 3. Aim dash - I configured the settings for the dash as follows and transmitted to the unit using Race Studio 3; ECU Manufacturer - Link ECU Model - CAN_BUS_BASE_LCC ECU Channels - All manually set to 20 Hz If you can shed any light as to why the dash is not reading the ecu data I'd be very grateful.

Simon Posted December 4, 2017 Report Share Posted December 4, 2017 If you go to the runtimes (F12) and then to the CAN tab are you seeing errors for can in here? Also you have the correct CAN port connected on the ECU as later units have both CAN1 and 2 connections available. Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted January 30, 2018 Author Report Share Posted January 30, 2018 Hi Simon, Apologies for the delayed response but my car went into storage for the winter and I have just got it back. I've now checked the CAN runtimes and the results are as attached. I've also taken a screenshot of the settings for the dash and the ecu (I tried swapping the settings between CAN 1 and CAN 2). I read about problems with the CANDASH cable so I cut all of the cables back to the connector except the white and green; the white is connected to the dash CAN + and the green to the dash CAN -. There is no information from the ecu being displayed so any help you can provide would be much appreciated. thanks, John AIM MXL 2.docx Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 30, 2018 Report Share Posted January 30, 2018 In your attached doc you have your CAN bit rate set to 500kbit, it should be 1Mbit for the AIM "CAN_BUS_BASE_LCC" template. Can you change that to 1Mbit, store, then reboot both devices. Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted January 31, 2018 Author Report Share Posted January 31, 2018 Hi Adam, Thanks for the steer; I will make that change on Friday and see if it works, John Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted February 2, 2018 Author Report Share Posted February 2, 2018 Hi Adam, I set the bit rate to 1Mbit as attached - still nothing from the ecu on the display. John AIM MXL 2.docx Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 6, 2018 Report Share Posted February 6, 2018 Can you attach your map. Also, I believe the MXL2 has 2 CAN ports, one on the big connector and one on the small connector. You are connected to the big one right? Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted February 6, 2018 Author Report Share Posted February 6, 2018 Hi Adam, Attached is my map. The dash has a 22-pin and a 37-pin connector. It was supplied with a 37-pin harness and that is what I am using. On the attached info sheet I am connected to cables 8 and 9.

Adamw Posted February 7, 2018 Report Share Posted February 7, 2018 Ok, CAN settings in your map look ok and when I load it into an ECU here Im getting correct looking data broadcast out. So Im running out of ideas, but your errors suggest there is no acknowledge coming from the dash. I assume you are using a Link CANPCB cable(not a 3rd party item) for connecting to the CAN socket and it is plugged into the 5pin socket labelled CAN1/RS232? Can you try swapping the CAN H & CAN L over (no harm can be done). Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted February 7, 2018 Author Report Share Posted February 7, 2018 Hi Adam, I bought a Link CANDASH cable that is connected to a comms lead that hangs out of the ecu (the same comms lead that I attach my laptop to). I stripped all of the cables out of the CANDASH apart from CAN H and CAN L John Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 7, 2018 Report Share Posted February 7, 2018 16 minutes ago, F430Jonesey said: (the same comms lead that I attach my laptop to). OK, now we are getting somewhere. That is not a CAN port. That is USB for the PC connection only. The CAN port is inside (2 of them) and you will need another CANPCB cable to access it. http://dealers.linkecu.com/CANPCB_2 Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted February 7, 2018 Author Report Share Posted February 7, 2018 Hi Adam, Thanks for that; it explains why I've been struggling. I've ordered a CANPCB cable and will fit it on Friday. John Quote Link to comment Share on other sites More sharing options...
F430Jonesey Posted February 9, 2018 Author Report Share Posted February 9, 2018 Hi Adam, Works perfectly now. I just want to thank you and Simon for your assistance, it's excellent customer service. John Quote Link to comment Share on other sites More sharing options...
