Mcfly94 Posted July 31, 2020 Report Share Posted July 31, 2020 Hey guys I’m having trouble streaming my analogue volt input to my AEM CD5 via CAN which I setup a calibration in the ecu and seems to be pretty accurate. I’ve got it streaming to the CD5 but the value doesn’t match; at 25% fuel dash showed 25 % but now the ecu is reading 85% the dash is now reading 42%. I’m assuming an offset and or scalar needs to implemented? Is the a way to calculate what’s needs to be done? What do I need to do to get it to work? I have attached my tune and dash config if anyone can assist? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 31, 2020 Report Share Posted July 31, 2020 In your ECU config if we look at the visual representation of the CAN frame you can see fuel level is sitting nicely in Byte 2 & 3. However if we look at the visual representation in the dash config (it is laid out vertical rather than horizontal) then you can see fuel level is sitting in Byte 1 & 2... Pic below. So change your fuel level start bit to 24 should solve it. Quote Link to comment Share on other sites More sharing options...
