<p>I was looking for something like this and found your website.</p>
<p>I'm preparing a car (My car), with another engine but using the same wires inside.</p>
<p>But I wanted something like your project, to apply on it, since ECU is very limited to give values without a PC nearby.</p>
<p>I will put new sensors, different from the ones used by ECU and wanted something to make the reading and to show in LCD like yours.</p>
<p>Do you still work on this?</p>
<p>Thanks.</p>The Engine Control Unit monitor project - limpkinurn:md5:1e4a01f07ad85fd0a293855209f06b162015-01-05T00:22:38+01:002015-01-05T00:23:04+01:00limpkin<p>@<a href="https://www.limpkin.fr/index.php?post/2011/01/11/The-Engine-Control-Unit-monitor-project#c2844" rel="ugc nofollow">Denis Köllner</a> : Sorry, I'm not planning to release it!</p>The Engine Control Unit monitor project - Denis Köllnerurn:md5:4cfc7768949add8bda91c73476d5ef012015-01-01T13:24:33+01:002015-01-05T00:21:31+01:00Denis Köllner<p>Hi,</p>
<p>that is a very nice Project. I'm searching a long time for such an Displayunit. But I want to use three MAX31855 for the ExhaustGasTemperature sensoring (pre Turbo 1,2 and one for the Catalytic). Further to oil temperature, pressure and MAP should be measured.<br />
All other data are logged with my GREDDY Emanage.<br />
Are there a possibility to get the source code?</p>
<p>Thanks for the nice Project<br />

In each page of your schematics you have VCC flowing through a capacitor network to ground, I'm assuming I'm misreading this. Could you clarify for me?

Moreover, sensors are not directly connected to the car Vcc, but to 5V coming from the ECU :)</p>The Engine Control Unit monitor project - Nigelurn:md5:70624f27ab2468c5326fc9192ed3aacd2011-02-15T12:06:43+01:002011-02-15T15:09:52+01:00Nigel<p>Hi, I am in the beginning stages of doing something similar and I stumbled across your build. I had a question involving the analog inputs. Are the sensors sent a consistent baseline voltage or does it fluctuate with the fluctuations of the car battery's voltage? I'm just worried about identical voltages meaning different values depending on VBatt and I am unsure how to remedy this if this is the case (The controller I'll probably be using does not have a VRef for it's analog ports)</p>The Engine Control Unit monitor project - limpkinurn:md5:26b28fb0ff60ab39614f4bac4d3d3ea52011-02-09T18:48:54+01:002011-02-09T18:49:27+01:00limpkin<p>@<a href="https://www.limpkin.fr/index.php?post/2011/01/11/The-Engine-Control-Unit-monitor-project#c48" rel="ugc nofollow">cwd</a> :Well I don't think so... this has been made for another brand of vehicles :)</p>The Engine Control Unit monitor project - cwdurn:md5:91f5f914e1fec7fc0694ee36961e78722011-02-09T14:17:55+01:002011-02-09T18:48:44+01:00cwd<p>Really Amazing!

I'll send you an email. Concerning the arduino / bt solution, I don't know of existing solutions but i am sure that you could readapt some existing project found on the web :).</p>The Engine Control Unit monitor project - marcurn:md5:5589d9a7c33fbd2e2b1fba47e5cc35d12011-02-03T13:01:03+01:002011-02-03T13:39:24+01:00marc<p>Are you selling these as a kit? if so how much? I am trying to build a dashboard for my jeep using an arduino to read the sensors, firmata as the firmware and using flash on a laptop to display the data. I have that working but would rather have a system that is more rugged and self contained. If I buy seperate guages for my jeep they end up costing about $50 more or less each. Another idea I have is using arduino / bluetooth and android tablet?</p>The Engine Control Unit monitor project - limpkinurn:md5:0dcc4a0abfb93edff3b0456d5a2b85c32011-01-30T20:09:11+01:002011-01-30T20:09:07+01:00limpkin<p>Hey Marc,</p>
<p>Nothing is over your head... it is just a matter of spending some time to get all the aspects of the problem :).<br />
You can get one screen on farnell (look for pmoled 5.5"). I think it would be possible to interface with arduino :).</p>The Engine Control Unit monitor project - Marcurn:md5:da0dc8abe2704ffad71a6afb99e0398d2011-01-30T13:57:16+01:002011-01-30T20:06:57+01:00Marc<p>Great project! definitly over my head.<br />
Where can I source one of those OLED screens and do you think it would be possible to interface it with a arduino ? Thanks for showing us what is possible. How much are you selling these for?</p>The Engine Control Unit monitor project - limpkinurn:md5:8bff2104a0a4e61ad052864db08b16102011-01-29T12:29:13+01:002011-01-29T12:29:25+01:00limpkin<p>Hey Man!</p>
<p>Well it depends for how many people... I am quite busy these days :).<br />
Can you contact me to give me more info about this project?</p>
<p>Mat</p>The Engine Control Unit monitor project - selfsilenturn:md5:f61b61512978fb277dcc550d00351c052011-01-29T00:38:26+01:002011-01-29T11:41:37+01:00selfsilent<p>Looks amazing. Would you be interested in making a smaller, far more basic gauge for a particular car? We only need to display boost pressure, engine coolant temperature, RPM and time but over 2 smaller OLED screens.</p>
<p>The data would have to be collected off the LIN bus which is a 1 wire offshoot of the CAN bus.</p>
