dimitarbp Posted January 4, 2022 Report Share Posted January 4, 2022 Hello, I'm trying to make my life easier by showing the differential fuel pressure (fuel pressure - MGP) to a CANbus display (it cannot calculate it). I was having some fueling issues and I want to monitor this live. Does anyone know whether the differential fuel pressure is sent in the CAN stream, and if so what's the CAN id for it? I'm a newbie in this... Thanks in advance! Quote Link to comment Share on other sites More sharing options...
dx4picco Posted January 4, 2022 Report Share Posted January 4, 2022 What display do you use? Quote Link to comment Share on other sites More sharing options...
dimitarbp Posted January 4, 2022 Author Report Share Posted January 4, 2022 It's Canchecked MFD32. I played a bit with the CAN setup in Pclink and the display developers provide some custom streams, unfortunately without the differential fuel pressure...

Adamw Posted January 4, 2022 Report Share Posted January 4, 2022 You can load the "configurable generic dash stream" and swap the fuel pressure channel with differential fuel pressure. Quote Link to comment Share on other sites More sharing options...

Thanks for the idea, Adam! Nevertheless I dont manage to pull this off. The display works fine with the settings from When I try to load a custom stream for a generic dash it appears with several frames, and it absolutely doesnt work with the display. I reckon the display's Link profile is worked out for mode 'Transmit Generic Dash 2', because if I switch to mode 'Transmit Generic Dash' it doesnt work similarly to the custom stream for generic dash. One thing I cannot wrap my head around is how to connect the values for the Fuel Pressure (see below) with the expected values in my CanChecked dash (see below)... Another thing that I notice is that the standard Link profile in my display has the different parameters in different CAN ID numbers... (i.e. Fuel pressure is in CAN ID 0x7D1, while Oil temp is in 0x7D0 ...) I dont know if this has any effect... Any idea how to solve this..? Maybe you have the .lcs file for the 'Generic Dash 2' mode? What I thought was a simple addition turned out to be a total headache ... Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 6, 2022 Report Share Posted January 6, 2022 What stream and ID does the CANChecked documentation tell you to use? Quote Link to comment Share on other sites More sharing options...
dimitarbp Posted January 6, 2022 Author Report Share Posted January 6, 2022 They don't specify anything. I just have the default values for the LinkECU profile. Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 6, 2022 Report Share Posted January 6, 2022 This document here says "Generic Dash 2 on ID2000 and lists a few optional streams: https://www.canchecked.de/wp-content/uploads/connection-guide_LinkECU.pdf There are .lcs files labeled "DASH2PRO Stream#" in the PC Link CAN folder, these are the same as Generic Dash 2 so you can use these. You need to set these 4 streams up as seperate channels - transmit user stream 1-4, and you need to set them up on 4 sequential ID's - so in this case stream 1 will need ID2000, stream 2 ID2001, Stream 3 ID2002, etc. Quote Link to comment Share on other sites More sharing options...
dimitarbp Posted January 7, 2022 Author Report Share Posted January 7, 2022 Thanks for the help! The only place I can see Dash2Pro in the CAN Setup is Data->Mode, much like the 'Generic Dash 2' mode. I dont have any .lcs files with DASH2PRO in the name. Maybe you could share them? Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 7, 2022 Report Share Posted January 7, 2022 Files attached DASH2Pro stream 1 ID1000.lcs DASH2Pro stream 2 ID1001.lcs DASH2Pro stream 3 ID1002.lcs DASH2Pro stream 4 ID1003.lcs Quote Link to comment Share on other sites More sharing options...
dimitarbp Posted January 7, 2022 Author Report Share Posted January 7, 2022 It works out perfect! Thank you for your time. The default LinkECU CAN settings in my display were exactly made for these 4 files (or mode 'Generic Display 2'). I just had to adjust the CAN ID accordingly.
