That is correct.

Some systems, the Edge I know for sure, require the O2 sensors to remain in the exhaust stream. Hence the need for the bung holes. The better systems, Smarty and H&S among others, have done their home work and do not require the O2 sensors to remain in place. The first gen BADP delete kit I have on my truck right now came with a down pipe and it had the sensor bung in it and one in the delete pipe. My O2 sensors are in place, just unplugged and doing nothing more than stopping a huge exhaust leak.

The sims are nothing more than resistors that read a set resistance that corresponds to a pre-determined temp that substitute for the three temp probes in the stock exhaust.

This is all very interesting to me, I hope this thread continues. But being new to diesels I wish someone could post some pics. To me its like a 4 year old puttin a water heater back together.

Thanks goodness for the Smarty. Years ago, I remember reading posts of guys that seemed they'd give their first born for a Smarty for the 6.7 because they loved it so much for the previous generations. I thought someone was going to die and it could not happen soon enough.

This being my first diesel, I did not have much of a clue as to why but I certainly new there were a lot of "Smart" people on this site and they must be on to something. Hence, when that sucker came out, I was on top of it and understand why now. The fact that it has so much power, options, flexibility, and can fix these emmisions with a few simple mods [director] is the "bomb".

You can delete in California? How is that possible without getting away with it? If so, I'm ALL ears! Is there a way to delete the State Legislature at the same time?[dummy]

Well the point of the mega-engr "California style" deletes is that they are easily put back to stock, say 2-3 hours, so that the vehicle can be inspected as a stock vehicle with stock programming, then returned to a Smarty enabled deleted vehicle in the same day.


Unfortunately, the state legislature would take a bit more BOMBing than Smarty alone can offer... [laugh]

Its all a big dog and pony show and one needs to figure out how to have their cake and eat it too.

Run with the deletes 99.9% of the time and have it stock 0.01% for when it needs to pass its tests.

Main point is to make sure one can easily go backwards if needed. It is still a federal issue to tamper with vehicle emmisions wherever you are.
