paulr33 Posted March 16, 2016 Report Share Posted March 16, 2016 I have a friend at work helping me, who has done heaps of electrical engineering and has done adruino's before etc so he is well equippedI think first we will do the setup in the first post using the ardruino and the LCD display and then once it all works, we will tackle if we can make a CANBUS pass through box to feed the KMS display manipulated CANBUS packets from the VIPEC so the KMS display shows them correctly. This saves me selling my ecu and buying a Link G4 Quote Link to comment Share on other sites More sharing options...
paulr33 Posted April 11, 2016 Report Share Posted April 11, 2016 (edited) this is what my friend is going to build for meobviously made up using dummy #'s and bullshit data so far Edited April 11, 2016 by paulr33 Quote Link to comment Share on other sites More sharing options...
Scott Posted April 11, 2016 Report Share Posted April 11, 2016 Good to see it coming together. How big is the screen? Quote Link to comment Share on other sites More sharing options...
paulr33 Posted April 11, 2016 Report Share Posted April 11, 2016 the screen is about credit card sizedso ideal for the dashboard Quote Link to comment Share on other sites More sharing options...
paulr33 Posted April 27, 2016 Report Share Posted April 27, 2016 I've ordered all the parts for this build so hopefully in a few weeks I can show a working demo Quote Link to comment Share on other sites More sharing options...
Scott Posted April 27, 2016 Report Share Posted April 27, 2016 cool make a little youtube video. I'm sure there are others interested in something like this. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted April 28, 2016 Report Share Posted April 28, 2016 Yes will do once finished. With regards to the "twisted" CAN Lo Hi wires I was thinking of using a pair of wires from a Cat5 Ethernet cable as these are pre twisted to an industry standard already. I.e use the green / light green pair from inside a Cat5 lead as my CAN cable. Would this be OK? Quote Link to comment Share on other sites More sharing options...
Scott Posted April 28, 2016 Report Share Posted April 28, 2016 I don't know anyone who has done it before, but yes, should work well. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted April 30, 2016 Report Share Posted April 30, 2016 This is inside a CAT5 lead, one of these pairs as my CANBUS Lo/Hi wire Quote Link to comment Share on other sites More sharing options...

paulr33 Posted May 2, 2016 Report Share Posted May 2, 2016 CAN enabled v44 and can shield will arrive today via post. Looking forward to this build Quote Link to comment Share on other sites More sharing options...

paulr33 Posted May 4, 2016 Report Share Posted May 4, 2016 That's pretty cool and we'll done. How did you make the controller and screen? Is it ardrunio or something else? job well done, I like the colours Quote Link to comment Share on other sites More sharing options...

paulr33 Posted May 20, 2016 Report Share Posted May 20, 2016 this is how i plan on setting it up. ill have to cut the metal cover plate as all the cables dont fit out of the front of the face plate no more. ill cut the CANPCB lead and fit my colour matched CAT5 lead to the green and white pair and away we go Quote Link to comment Share on other sites More sharing options...
paulr33 Posted May 22, 2016 Report Share Posted May 22, 2016 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 Scott 1 Quote Link to comment Share on other sites More sharing options...
ssddaa Posted May 24, 2016 Report Share Posted May 24, 2016 cool make a little youtube video. I'm sure there are others interested in something like this.Hi Scotti remember speaking on the phone a year ago about the data stream from V series as you can see i got it now, fully working at 7 fps and logging the data on SD (1Mb per 1hour, all 56 parameters)BUT...... there is always one buti flipped my whole code upside down and i still can not read DI6 which suppose to be %Ethanol. i see the reading on the laptop, but not on the screen.i read DI3, DI4 properly and see them on the screen that are streamed beforei read Target AFR and see that on the screen as well, streamed after you can see in the log file, the values are correct before and after DI6 but it shows zeroas per the short/long data stream description it is a word with multiplier 1, offset 0 and no decimal pointplease HEEEEELP Quote Link to comment Share on other sites More sharing options...
Scott Posted May 25, 2016 Report Share Posted May 25, 2016 Hi ssddaa,The serial long data-stream contains 'DI6 Speed' and 'DI 6 Freq', if you look at the parameters in the runtime value window of PCLink/VTS, what do they read? Your screenshot above shows DI 6 Speed, where-as I would expect DI 6 Frequency to show the data. Quote Link to comment Share on other sites More sharing options...
ssddaa Posted May 25, 2016 Report Share Posted May 25, 2016 (edited) log file has DI6 speed only because I named all parameters in array in my code. The stream contains the data but reads 0 all time. in runtime values it shows 56.9Hz. If shown as % ethanol then it shows 6, and also the temperature reads correct in VTS screen. I write the code so any data can be calculated and adjusted to correspond to the real number, sadly it reads 0 only. if you look at the figures, you will see that all numbers are raw data (as sent from the ECU) i saw in the software update log what do you mean. 4.9.9 onwards does not stream frequency data for digital inputs. so it means my code is good and ECU stream is right. how to trick the ECU to send any data as speed then???????????????????????

Scott Posted May 26, 2016 Report Share Posted May 26, 2016 Hi ssddaa, we'll setup a G4 ECU and set DI 6 to ethanol content and check the serial long datastream, and then come back to you.Scott Quote Link to comment Share on other sites More sharing options...
Scott Posted May 27, 2016 Report Share Posted May 27, 2016 (edited) So we had a look today, and you (and our documentation) are correct, from firmware 4.9.9 onwards the Digital Input frequency is not transmitted. Unless you need something in version 4.9.9 (or later), I would recommend downgrading your firmware to version 4.9.8 so that you can receive the frequency of DI6 over serial.If you do need firmware 4.9.9 (or later) one way to trick the ECU will be to set DI6 to an unused speed function (maybe Ground Spd Left), then enter a calibration number of 360. This will result in your speed and frequency number being the same. You could then allocate 'SPEED DI 6' as an axis on the 4D fuel table. Set the row headings to range from 50 to 150, as this is the output range of the ethanol content sensor.The serial data stream will output a range of 50 to 150 also, and you will have to make your logger convert this into % ethanol.

ssddaa Posted May 27, 2016 Report Share Posted May 27, 2016 thank you for confirming that Scotti really want to leave downgrading option as last resort (a lot more to modify in my code)i figured out the DI6 speed possibility but i believe i will loose the ethanol temp that way, is there any way of keeping the duty as well, so then it can be recalculated as temperature in my code Quote Link to comment Share on other sites More sharing options...
