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

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 

some issues to work through, but its coming along =)

my screen display has been shipped so should have it in a day or so. the display has a pretty powerful graphics library IDE system and i can pretty much do whatever within the code to display gauges, bar graphs, digit displays etc so the possibilities is endless. the one issue i have is screen size real estate as the display is 3.2" because i didnt want a mega display panel on my evo dash. ill do a full detailed write up including parts and part #'s once i have working

good news, got it working first shot with new controller board. this is what it should look like using the simple CAN_RECIEVE test demo. ill write up a full howto for those playing at home as its taken me a good few weeks to get to this point
 

hi all, we fixed a number of issues and now have a working canbus board, in short, we changed the ardunio board, hopefully can demo it tonight.

ive installed my v44 CANBUS enabled ECU and all is OK. hopefully can post some pics up this week if i get a working demo of the ardrunio
