I have a 2015 Cooper S with the NM Engineering Power Module. I've had it for 2 years at least with no problems, but just saw that Dinan makes the Elite Performance Tuner with bigger power gains over the NM product. The Dinan hooks up to 3 sensors vs one for the NM. I'm curious if anyone has made the switch from the NM to the Dinan Elite and what the experience is like. My power definitely is better since I added the NM. I run it on stage 2, but just use 91 octane. I don't track the car, and NM said I would not experience any issues on stage 2 with 91 octane. My MPG actually improved by 1 mpg.

 

I have and the Elite is definitely worth the upgrade as it makes the power more consistent along the entire power band. The NM module gives you that big boost at low RPMs and peters off while the Elite module has more control over the engine and it works better at all engine speeds. Installation is just as easy (two more connectors) and it's warrantied as well.

MPG did take a hit since it now has control over the fuel as well. My Clubman was getting ~25 mpg before now it gets closer to 22, but I'm always in SPORT and I'm definitely not driving conservative.

Overall, very happy with the purchase.

 

I had Dinan Sport which is very similar with NM, single sensor. Works well if you just want that sudden boost. I swapped it out to Elite and it was day and night. Car reacts just like how it was from manufacture but lot more manageable. I don't even put it in sport mode anymore.

 

I ordered the Elite to replace my NM Module a while back. Before I could install it Bytetronik came out with their stage one OBD Flash Tune. I returned the Elite without even opening the box. Trying to decide if I want the stage 2 tune now.

 

Skip it and go to stage 8, V8!!!

 

^^ stage 8 might reduce your MPG

 

But it would definitely increase the value of my Goodyear stock!

 

Wondering about the torque steer.................ya think it would be noticeable over stock?

 

Yes, torque steer is definitely more pronounce and I still think its manageable. Doesn't affect me when I'm doing autocross

 

Torque steer with the V8!!

 

^

Yes, was referring to the V8.
