I have a 2023 Roxor all weather model that I purchased new last year from a Roxor dealer. My ranch in Colorado is at 7500 feet and, immediately after taking delivery, I noticed that the engine would occasionally bog down and smoke when going uphill. This happened only a handful of times immediately after taking delivery of the machine. After putting on a few hundred miles the problem abated. Nevertheless, at the bottom of a very steep hill after using first gear for downhill braking, the engine would hesitate and stumble when level ground was reached when I began to accelerate. This past winter I moved the Roxor to a location that I own in Arizona that is about 5,000 feet elevation, about 2,500 feet lower than the CO ranch. The machine seemed to run a little better there. Don't know if the problem was related to the lower elevation or related to the mileage which was about 500 miles when it arrived in AZ.
I decided to take the Roxor to another dealer which is about an hour and a half away from my location in AZ. We are in a fairly remote location in AZ. This was a little over a month ago. After looking over the Roxor and finding nothing wrong, the mechanic decided (at my suggestion) to contact Mahindra to see if there might be an upgrade to the ECU software. According to the dealer, Mahindra responded that they were in the process of finalizing a new software upgrade for the ECU. The dealer told me that as soon as Mahindra got back to them and advised him that the software upgrade was available he would call me. A few weeks later I received a call from the dealer. He said that if I would remove the ECU - a pretty easy job as it is easily accessible and only 4 nuts need to be removed along with a ground wire and the plug-in wiring harness - and take it to him he would ship it to Mahindra for the new ECU flash. It took about a week and a half before the ECU was returned to me. I asked the dealer what Mahindra's comments were regarding the upgraded flash and he stated that it was primarily to address complaints from owners, like me, who were running at higher altitudes.
I can't say that there has been a dramatic change to the engine since reinstalling the ECU. However, the engine does seem to run a little better at this altitude (5,000 FT). It seems to have more power, runs more smoothly, and climbs moderate hills better in second gear when it would previously have been necessary to shift to first to prevent lugging. It is still RPM limited just like it was originally so no change there. As I said, I have noticed no earth shaking difference but, and this may partly be my imagination, it does feel generally better than it did prior to the software upgrade (I have owned and driven all manner of diesels for much of my life). I would be the first to admit that my comments on the perceived improvements are not based on a scientific evaluation. They are more of a subjective determination. Nevertheless, all in all it was probably worth having it done, particularly considering that the process of removal and reinstallation was quick and easy and there was no charge either from the dealer or Mahindra for the upgrade as the machine is still under warranty. Hoping that the folks out there who are offering ECU software upgrades are able to come up with a solution for an enhanced version of the flash which I understand is available for older versions of the Roxor. It is a great vehicle but, personally, I don't think the engine in its present configuration quite lives up to the full potential of the machine, particularly at higher elevations.
