You can broadcast on the ECU channel all you want as long as you're not trying to use a PID that's already in use.

Unless I'm wrong I think you are overthinking this. Is the ECU not responding to this request, so that the Arduino can reply? If so, logcfg.txt would require just a normal Mode 1 request. I have seen that in the sensor project Mode 0x01 with PID 0圎E ist used.

Or, can I tell Tactrix to use another requester ID or PID which is not responded by the ECU, but by the Arduino?.

How can record a broadcast message with Tactrix along other OBD2 polls?.

Sensor1_V sensor2_V (end a line break, that's what the tactrix.println() does). Paramid = 1Long story short, send sensor data separated by and end each row with a line break. in the case of the AEM UEGO, there is simply one column of data, and it is already scaled appropriately numbers by choosing a paramid starting at 1 which indicates the column number you can sample data from a particular column of considered to mark the beginning of a new row of data. furthermore, the carriage return and line feed characters are the ascii channel considers anything other than the characters to be a

all of these can be changed for other scenarios the default baud rate and setting are 9600,N,8,1. the default protocolid is 9, which corresponds to the 3/32" jack receive-only serial port the "ascii" channel type can listen on any protocol for incoming numeric text Give your Arduino some juice, I've used my laptop so far but you can source probably source voltage somewhere in the cabin.Ĭode: -aem. Connect your 2.5mm Stereo Jack to Tactrix OpenPort stereo jack input. Connect your 2.5mm Stereo Jack to MAX3232Īn image will be better illustrate this (note they're using PIN 7 for tx): MAX3232 TX > Arduino TX (pin 6 in my case, more on that later)

Connect your sensors to Arduino analog inputs. Connect your sensors to an analog/RS232 converter. Sensors > 5v analog > RS232 conversion > 2.5mm Stereo Jack > Tactrix > Happiness You'll connect your sensors to an a device than can receive their 5v analog input and transform it an RS232 data stream which will be sent to through a 2.5mm Stereo Jack connected to the OpenPort jack input and add a bit of configuration and that's it. Technically something like this could work but I haven't properly read the documentation nor do I own the product. I use an Arduino+MAX3232 but you could technically use anything that is able to produce an RS232 signal/stream that respect the OpenPort protocol. This won't be a very detailed how to but you should be able to get the idea. Long story short, I've found out that Tactrix has RS232 input which can be used very easily to add any amount of external sensor, eg: oil pressure, fuel pressure, O2 sensor, Knock sensor, WMI flow sensor, etc.
