2.7 Tune Results (with 4.10 gearing, video)

[DrunkenSlug]

Here’s my 2025 mahindra roxor full send with 4.10 gearing and the stock 29” wheels. Full throttle, relatively flat. Does great! This is what it should have been from factory. Also this tune got rid of the weird stumble/shake I had around 1800Can’t wait for a lift and 35”. Great job to wade and the team at @dieselfreak.
Speedo is unaffected. I have it unplugged for the video since it's inaccurate due to my gearing being 4.10. Speedo on the phone is accurate.

That's great 👍 just sent my ECU in yesterday can't wait to get it back. Thanks for the video

Will be great to see speed with the stock rear end! Thanks for posting!

Awesome! Looks go to me! Thinking of changing to 4:10 gearing as well. What speeds are you running at while idling in first and second gear?

Does the stock speedometer not functional after tune ?

Yeah it works fine, mine was unplugged for the video so you guys wouldn't see the false reading (since I dont have stock gears). The phone gps speedo is accurate in the video

Why didn't you have the tire size calibrated with the tune?

It’s not offered on the 2.7 tune unfortunately. I asked wade about it.

Awe man what a bummer!

Might be able to still do it the old fashioned way if you really wanted to correct it, by sourcing a different tooth count gear. The Roxor uses an 18 tooth that runs the electronic speedo unit on the tcase. The gear looked like a standard Dana 18 gear when I had mine apart, although I have not tried the swap, so if someone does and it works, please post it!

Update- driving it a bit more, feel great! BUT I’ve got a check engine light that flashes every few minutes. Constantly. Random amount of flashes, from 2 flashes to a solid 3 minutes of flashing, then it goes off again. But it always does it. Swapped a fuel filter just to see if that was it, nope. Wades investigating, said 2 of us have had this happen so far (so doesn’t seem widespread, I’m sure there’s tons of these sold so far).

I wonder if it has something to do with the boost from the turbo. I had an old ford truck with a 7.3l powerstroke and after we put a tuner on there the check engine light would come on briefly if we hit 20-25 psi boost at higher rpm’s. It would come on for a few minutes then turn off without any issue.

Any update on the flashing check engine light? Mine did the same.. unplugged the water in fuel sensor and it didn’t happen again. Flashing CEL due to a sensitive water in fuel sensor has been common for me, but it sounds like you eliminated that possibility when you changed the fuel filter and it continued to happen. That is, unless, there actually IS high water content in the fuel.

Nah no update yet, wade said he’s working on a diagnostic tool for the 2.7 to figure out why a few of us have it happening. My water fuel separator is unplugged all together, I forgot to swap it to the new filter when I’ did the first filter change 🤦‍♂️. But nah, that’s not it. It’s weird, it only does it if you’re not giving it a good amount of throttle. Cruising it does it, accelerating it doesn’t.
