paulr33 Posted July 25, 2016 Report Share Posted July 25, 2016 No worries. I'm using arduino Uno and version 2 of their 4d display shield. The screen is the uLCD32-PT Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 26, 2016 Report Share Posted July 26, 2016 I think I may have it working on one shield, update soon Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 28, 2016 Report Share Posted July 28, 2016 hi all, i have it all working end to end, now just some final code to change the numbers on my display. very excited and cant wait to have it all working for final demo. very excited. only issue i have is i dont have oil temp, oil pressure or exhaust temp sensors to the vipec yet so they wont show values just yet Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 28, 2016 Report Share Posted July 28, 2016 hi support, one question, i want to pass EGT which i will have hooked upto AN Volt 6. will the output from this parameter in CANBUS be the actual voltage or the caluclated EGT value? I think i simply select AN Volt 6 and connect the relevant sensor and then choose Calc Table 5 for example to dial in the LOG scaling for EGT range.

Scott Posted July 29, 2016 Report Share Posted July 29, 2016 Hi Paul,Looking forward to the demo. If you have AN V6 set to 'EGT (0-5V)' then the data should come through as the EGT value and not the actual voltage.The input to the volt channel will need to come from an EGT amplifier as the K type thermocouple can not be connected directly.Scott Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 29, 2016 Report Share Posted July 29, 2016 Ok no problems and thanks for clarification, I will be using an EGT controller and sensor and run the analogue 0-5v output from the EGT controller to the vipec AN Volt 6 Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 30, 2016 Report Share Posted July 30, 2016 some issues to work through, but its coming along =) rest of the pics for anyone interestedhttp://paulr33.com/evo/ecu/can-display/page_01.htm davidbek95 1 Quote Link to comment Share on other sites More sharing options...
paulr33 Posted July 31, 2016 Report Share Posted July 31, 2016 did a first test run yesterday, the update rate is pretty good and thats updating each value every time on the screen even if it doesnt change. i found TPS was pretty useless and gear wasnt quite right as i need to finish 5th and 6th gear calibration. i found the stand too big and i couldnt see the values properly on the angle. but the reliablity was perfect with the CAN protocol working as needed and my code being stable - theres no error checking in it.i found a $3.95 plastic case at jaycar that magically fits so ill ditch the 4d display stand and use this instead.have also remodelled the display to suit more meaningful sensors until i order EGT, OIL Temp and Oil pressure.the green square above 02 CL will come when vipec is running closed loop via wideband so it should cycle this light on at light cruise.ill order another apexi stand as this fits my requirements perfectly and it should match the existing dash setup davidbek95 1 Quote Link to comment Share on other sites More sharing options...
Scott Posted August 1, 2016 Report Share Posted August 1, 2016 Good effort, I'm guessing the display will keep on evolving as you think of new and better things to display. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 1, 2016 Report Share Posted August 1, 2016 Yeah I found quickly some things were pointless and others were more important hence the number of changes. Still need to document the whole build and finalise my new sensors and cabling so that the arduino can sit in the glovebox and my display sits on a dash mounted stand very happy with it so far and glad to have CANBUS working on the vipec. Once the protocol is working and we understand how sensors come across the stream the possibilities are endless for what can be shown and how to represent it. For example I want a light to come on when closed loop is actively trimming fuel and I wanted oil pressure in kgcm2 not KPA. These are all possible davidbek95 1 Quote Link to comment Share on other sites More sharing options...
Scott Posted August 1, 2016 Report Share Posted August 1, 2016 Yeah, it is very handy. Next you will be wanting to upgrade to a G4+ so you can do custom CAN transmitting Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 4, 2016 Report Share Posted August 4, 2016 Is there any way to transmit the "statistics" that the ECU records , I.e # of engine starts, # of fuel cuts Quote Link to comment Share on other sites More sharing options...
Scott Posted August 4, 2016 Report Share Posted August 4, 2016 Hi Paul,I can't think of anyway to do this. Is it possible for the arduino to do this by monitoring and storing values?Scott Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 5, 2016 Report Share Posted August 5, 2016 Yeah the arduino has onboard SD card that I can write to but was wondering if there was a way to send the vipec global ECU stats across. Don't worry was just pie in the sky thinking Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 7, 2016 Report Share Posted August 7, 2016 some more testing, the green square turning on is for when 02 closed loop via wideband is running (pretty nifty)INJ DUTY not working but i know why, so an easy fix. stand should arrive this weekhttps://youtu.be/NvUU-iycuDs davidbek95 1 Quote Link to comment Share on other sites More sharing options...
Scott Posted August 8, 2016 Report Share Posted August 8, 2016 Looks good, especially compared to the other screen you have there.Scott Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 8, 2016 Report Share Posted August 8, 2016 Yeah in comparison it looks heaps better than the Apexi RSM. The RSM runs a Vacuum fluroscent display and it's basically dot matrix. The uLCD32 is really sharp and bright. At night is amazing. The iPhone video capture and YouTube format really dull down quality of the display in the video davidbek95 1 Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 20, 2016 Report Share Posted August 20, 2016 About to order oil temp, oil pressure and EGT sensors for the vipec and also waiting on my 2.7m extension cable so I can have the arduino in my glovebox and the screen on the dash Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 26, 2016 Report Share Posted August 26, 2016 managed to get an extension cable made up succesfully using 3 x PC USB Dupont cables which are a 5 pin flat cable - the exact same type used by the arduino display adapter shield to the display screen so i have 2.7m of 5 pin loom cable shielded which is plenty long enough to get behind the evo dash and into the glovebox. tested and works well. new sensors next Scott 1 Quote Link to comment Share on other sites More sharing options...
twentyvalvevw Posted August 26, 2016 Report Share Posted August 26, 2016 I know this post is old. Any one here interested in showing their code? I just want to look at the interfaces and a overall board design so I can get a little feel for this. I am doing some basic with this but still have some stuff to do and other things.

paulr33 Posted August 29, 2016 Report Share Posted August 29, 2016 this is where im upto with the current display. some minor changes, now includes oil temp, oil pressure and exhaust temp.also included knock display status from the vipec and global knock triggered times # which reflects # of times vipec has trigger excessive knock and cut timing.i cant find a good symbol for pressure so i used * I know this post is old. Any one here interested in showing their code? I just want to look at the interfaces and a overall board design so I can get a little feel for this. I am doing some basic with this but still have some stuff to do and other things.hi,The board design is a simple arduino Uno with two shields (CANBUS shield & 4d displays systems shield). No other changes are required to the board and these are off the shelf items. the rest of the solution is simple arduino code to drive the CANBUS adapter and then display values on the 4d display. happy to post my code when it's finished CamB 1 Quote Link to comment Share on other sites More sharing options...
Scott Posted August 29, 2016 Report Share Posted August 29, 2016 also included knock display status from the vipec and global knock triggered times # which reflects # of times vipec has trigger excessive knock and cut timing.The Knock count is quite interesting. Probably something most people have no idea of unless they are looking back through logs.Scott Quote Link to comment Share on other sites More sharing options...
paulr33 Posted August 29, 2016 Report Share Posted August 29, 2016 Yeah I wanted to know that knock system is active (green box indicator) and also want to see how many times the vipec detects knock over the target value and cuts timing. Then I can sit at home analyse the logs and adjust the tune properly or diagnose cause of knock. I'm used to the PFC style knock alert which flashes the engine light so I'll probably do this as well but it's nice to see how many times the target has been reached Quote Link to comment Share on other sites More sharing options...
paulr33 Posted September 23, 2016 Report Share Posted September 23, 2016 Ordered new oil temp, oil pressure and EGT sensors and will get these soon. Then I can wire into vipec and finish the display.still on the todo list is to write up documentation and software code for this project Quote Link to comment Share on other sites More sharing options...
