Aim MXL2

Recommended Posts

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

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.

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.

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

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.

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).

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
