Sensor simulators for dpf delete?
The sensors in the exhaust are simple electronic devices. They are fed some voltage and they have some resistance that varies as whatever they are sensing varies. I think the thermocouples in the pyros actually generate some miniscule voltage that is read by the computer to determine temperature. Does anyone know, then, why it might be hard to engineer a simple electronic circuit that replaces each sensor in the exhaust? I have a very elementary understanding of electronics. I know what resistors, capacitors, relays and diodes do. Beyond that I can't do much. I know how to use a multimeter and how to manipulate Ohm's law and simple stuff like that. It seems possible that with some time and a multi meter, that I could find a way to send the correct signals back to the computer to make it think the sensors are there when they are not.
I already have a delete with a minimaxx, so I don't need to do this. My motivation for looking into this is because I HATE HATE HATE the epa and their twisted version of reality in which deleted trucks are spewing thousands of tons of pollution that are supposedly killing thousands of people.
They can kill the sources of tuners, but they can't kill an idea.
If we can work together as a team and this works, then it's also a way to delete without effecting the warranty. No computer modifications would need to be made and it would be totally reversible if we could come up with a way to plug these devices into the oem sensor plugs.
