Rossogy Posted November 9, 2020 Report Share Posted November 9, 2020 Hi Guys, Does the above ecu have a built in 120ohm resistor for Can termination? I have the Link (Aim) MXS Strada dash and it wont show data so im guessing i either need to activate the resistor in PCLink or i need to add a resistor in.. Any help is appreciated Thanks Ross Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 9, 2020 Report Share Posted November 9, 2020 The ECU has a CAN termination resistor built in. Check you are on recent firmware - the MXS stream was only added in 5.6.6 something. Also, assuming you have an Xtreme wire-in ECU, if you are using CAN 2, make sure DI9 & DI10 are set to off.

Thanks Adam, I'll Double check the firmware & DI9 & 10 today I will report back Thanks Quote Link to comment Share on other sites More sharing options...

Hi Adam, so just had a check.. DI9&10 are off and I’ve updated all firmware (ecu & dash) double checked I had the can wires the right way round. Still no communication to dash... any idea? I’ll upload my config and file once I’m home also. Thanks Ross Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 9, 2020 Report Share Posted November 9, 2020 Yeah, attach your ecu map and the dash config, and maybe some photos of you can wiring may help us spot something you missed. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 10, 2020 Report Share Posted November 10, 2020 I think the problem is the dash config. In your dash config, change the "ECU" to "LINK - CAN_BUS_BASE_LCC". I think the CAN BUS FULL stream you are trying to use is something very old from G3 or G4 days. Quote Link to comment Share on other sites More sharing options...
Rossogy Posted November 10, 2020 Author Report Share Posted November 10, 2020 Ive already tried changing between the three choices.. i had an issue with my older style Atom ecu and i had to add in a resistor on the ecu side. it was one of the early metal case G4+ Just looked back through my old config for the Atom and it was using the LINK - CAN_BUS_BASE_LCC (VER. 02.00.02) Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 10, 2020 Report Share Posted November 10, 2020 Select the correct ecu then give me the configs again. The ECU is showing acknowledge errors on CAN 2 so we need to see if they go away when the dash is set up correctly. Oh, in the ECU, turn the OBD off in the CAN setup screen too.

Rossogy Posted November 10, 2020 Author Report Share Posted November 10, 2020 Adam, Just changed all that you requested and its still the same. Any other ideas? I noticed in the runtime values that there are errors on CAN2 like you said. I double checked the wiring again and it is 100% correct Thanks for the help Ross MXS 1.2 Strada G4+ Xtreme2.zconfig 2JZGE+T VVTi Dash canbus2.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 10, 2020 Report Share Posted November 10, 2020 Both are configured correctly now. The transmit and acknowledge errors suggest there is a problem on the bus. Can you give us some photos of the wiring so a second set of eyes can confirm. Quote Link to comment Share on other sites More sharing options...

Hi Adam Pic shows white- Can H wired to B loom can2H green- Can L wired to b loom can2L wires are twisted to the dash also as requested if it’s over a distance Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 10, 2020 Report Share Posted November 10, 2020 Unplug both the ecu and dash, and check continuity from end to end. ECU pin 27 should have continuity to AIM pin 8 (14pin connector), and ECU 28 should beep through to AIM 9. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 11, 2020 Report Share Posted November 11, 2020 I dont have much else to suggest. So, to confirm, your white wire that is shown in the pic above in ECU B connector, is connected to the white wire that is in position 8 in the AIM 14pin plug? And the green wire connects to the Blue wire in pos 9 at the AIM end? terminals are pushed fully home in the housings etc? Quote Link to comment Share on other sites More sharing options...
