I was worried about that in the beginning, but I have yet to run into any issues with that. :)

Roxor ECM Power Tuning with Speed Limiter - Rox Tuning

I haven't had a tune done yet but might use this fellow. He can simply delete the governor or do something that will bump up performance.

Whatever I have done I'll probably get the EGR code deleted while they are in there. I still have the EGR on my engine but I will probably ditch it one of these days.

Hello everyone, I'm back again with another question about these tunes! When I spoke with the folks at KMS Performance, (Very nice people), I specifically asked them about the "EGR delete" on my tune as well. I was told that my tune would "eliminate the warning light associated with an EGR delete". Originally, I thought that by ordering a tune that included an EGR delete, the EGR system would stop working.

Please correct me if I'm wrong, but as of today, it is my understanding that EGR delete, when specifically referring to a tune, will only give me the ability to do the actual EGR delete, (Install the plates and remove the EGR crap) and merely not throw a code. I was under the impression that the EGR system was something that can be turned on and off through a tune, so I wasn't going to install the EGR plates (which I bought here on the forum), until the warranty ran out. In my mind, I had already addressed the EGR problem with a tune. Apparently that's not the case? As of my understanding this morning, in order to turn off the EGR system I have to actually block it off. I can't turn it off with a tune, the tune only effects whether or not I get a check engine light. Do I have that right?

I just installed the KMS stage 3 and absolutely love it. The power increase is amazing and it drives very well. Have to agree on keeping stock unit for warranty issues.

Vetdawg, I bought the KMS stage 3 also and waiting for delivery. Does it trow out any black smoke from the exaust or its clean?
They told me 115hp so it must make a hell of a difference. Cant wait.

Tinfoil I believe you are right. Sensors must be deleted so you dont get a code when you remove the EGR.

My KMS Stage 3 should be arriving soon. I am looking forward to the improved driving experience. In the meantime I'm really enjoying this Roxor. In many ways it reminds me of my VW Thing from 45 years ago - easy to buy, all steel body, standard transmission, off-road purpose, military roots from WWII, no frills, easy to work on, minimum electronics, basic seats and interior. I still can recall removing the doors. flipping the roof back, folding the windshield flat and heading out. I think you get the picture.

I did Diesel Freak stage 1. You keep the same factory ECM. So i like that. One of engineers I spoke with from Mahindra about this particular tune said it was safe for Roxor motor, clutch, etc. so I went that route. Stage 1 tune also provides rev limiter, too.

Yes, unfortunately this thing rolls coal, but I expect that they all do that with a tune.

Skymarc my KMS stage 3 does not smoke at all. It runs perfectly and power is awesome. I did not do any other engine mods only the ECU. I could not be happier

I too run the KMS Stage 3. I have not noticed excessive smoke. Strong pulling power is evident. Drivability is good with only a brief roughness when I first start it up. That goes away in a second or two and I don't experience it on the remaining starts that day. The increased fun factor of the driving experience is worth the cost and minor installation effort.

I ordered a KMS tune on October 1 and contacted them on the 16th about why it hadn't been shipped yet. They said that they had had some issues with their tune so they were re working it and they would have it out asap. Now its the 24th and I havent heard anything. This isn't instilling confidence. Have any of you with KMS had any serious issues, if so what are they? I am having a feeling that I made a mistake and should have went with diesel freak

I have not had any problems with my KMS stage 3 tune. I have put about 120 miles on it since I installed it. I have been very pleased with it so far so I do not think you made a bad choice at all. Let us know if you hear of any issues.

Here is what they said

"Unfortunately it appears that Mohindra made a few changes that we were unaware of when designing the new tune. A couple of the newer models have had some issues with the programming in our tune. We are bringing in a Roxor from a dealer to do testing, in order to update our tune. We are committed to selling only high quality products that deliver reliable power and performance, that our customers will be happy with for the long haul. We will get you updated as soon as we have completed testing and updated the tune. We don't anticipate it taking long to complete the process. Thank you so much for your patience." ---KMS Performance

I get a little paranoid messing with the computer systems.

Big reason I went with diesel freak they were the first ones to unlock the power available in this engine.

If Mahindra changed something recently either with the ECU, or the sensors in the engine, it could potentially impact all tunes for the newest Roxors. I will put KMS ecu in today for the first time tonight, and take it for a spin around the block and report back.

If there is an issue, the great thing about KMS, is you can put your old ECU back in. I am sure they will make it right.

The ECU tuning game is always dynamic. Wish me luck:)

Good luck I almost went with them for the very reason I could keep my old ecu.
