I know the country code location for this vehicle if you still needBmiller or bwilliam do you guy know where in the hex file do you change km to mph on a 09-10 Ram? Do you change country code if you can or something in the vin? Just trying to figure out programming like bmiller. It seems impossible to get a direct answer from anyone online. It can be done so someone knows lol.
First off, your question assumes you can add this sensor to you ECU. That's not always the case and for an 05-07 Chevy I don't know if it is or isn't possible. But assuming you can add the temperature sensor it's not as simple as just adding a sensor circuit to the input side of the ECU. I don't pretend to understand all of this but the CAN\Bus protocols operate with more required information than just adding the sensor. One required protocol to add is the priority the sensor is given to operate at. The vehicle limp home mode is an example of information priority. Most sensors also run within a cluster or shared information protocol. Otherwise there's no reason to not just add a stand alone trans temp gauge. Typically trans temp would be tied to RPM's, torque sensors, traction control, LSD if applicable, etc. You would have to write your own protocols to adapt the temp gauge to work within the operating limits of these other sensors. If you adapt the gauge to operate outside of the existing limits it may not work or it may foul up the clustered protocols. Who knows? There's more to it than just adding the gauge.I want to do nothing special. I just feel if someone has spent days, months, years etc collecting information that cannot easily be found, why not give them a little something for it. I also understand you can swap Kilo to miles using scan tool or cluster but sometimes you can't. I like to know little things, like if I add a trans temp gauge to a 05-07 chevy cluster I can load up eprom dump and goto line 50 position 9 of hex code and change 03 to 42. I don't want to search through forums while a customer is waiting .If I can give someone a little something that will save me time I,m saving money. Don't get me wrong I understand what you're saying and you are 100% correct .
