Branson 4815C PTO Dynamometer Test Results

This sounds so much like a CAT delete, now all you need is a resister to tell the O2 sensor what it wants to see. :laughing: I bet the "datalogger" can be spoofed instead of eliminated.

I am going to spoof the data logger. It will never log a second without the DPF installed. :thumbsup:

I will follow this with interest. Although my tractor won't have DPF it's still an interesting subject I have a little bit of experience with.

You don't need to spoof it. Just unplug it. My 3725 was delivered with the data logger unplugged. It ran fine with no dash lights.

It's too bad you didn't even try it. Unless you idle all the time it works well and the air you breathe is cleaner.

I think you missed the sarcasm in his message. The computer will think it's installed by telling it that's it's there and running fine.

Too bad the OP didn't get a baseline number for the emissions coming out the exhaust during the dyno test. That also would be interesting.:scratchchin:

Yes, I did (if that was how it was intended). I still think people should try just using the tractor for a while and worry about removing the DPF only if it's really a problem for them. It will be interesting to see what the dyno results are. And yea, numbers for the emissions would be interesting too.

It seems like a lot of work to make something to fake out the temperature and pressure sensors in the DPF when you can just unplug the logger. Of course with the logger unplugged the dealer can't usefully query it. But all it logs is the DPF's condition and if there's no DPF they don't need to query it. If it was me I'd want to make sure the dealer would still honor the warranty with the DPF (and logger) removed. But unless the dealer's a real stickler or has taken a dislike to you or Branson corporate makes them, I'd think they would. Unlike with EFI tractors it seems unlikely that removing the DPF on a Branson would cause an engine problem.

I don't know what the benefit would be with a tractor, it was more a technique for cars to keep the emissions folks off your back and keep the car from throwing codes.

I was being sarcastic. All I am going to do is remove the data logger. Good point about getting the emissions tested but I doubt they can do it at the small JD dealer I am using. I did not think to ask because I really am not concerned. I do know I will not be working the tractor hard enough to keep the filter clean. With my health being a concern later I am trying to handle as much now as I can.

The muffler shop could not get the flanges so I dropped it off at a machine shop to build them for me. I will pick the flanges up Friday and go back to muffler shop early next week.

I did verify with the dealer and the Branson rep that approves warranty work that it will not void the warranty.
