Racechip Results on a 2015 Mini Cooper 1.5L

Hi All!

I recently installed the Racechip GTS on my 2015 base model Mini with an automatic gearbox. The results are pretty good and I'd say the product was worth it. I conducted 2 tests, both with and without the Racechip. Before I installed the Racechip I could do 0-60mph in 7.6 seconds. The way I conducted the test was by simply "flooring it" from a standstill on a straight road with no upward or downward slope. I had driven around for 25 minutes before hand to make sure the engine and tires were relatively warm (the RIMS I'm running are the original 15" Heli Spoke 492s and the TIRES are Sumitomo HTR Enhance LX2 that are about halfway through they're lifespan). I did this three times and the best result was 7.59 seconds.

The next day, I fitted the Racechip GTS onto the car and the best 0-60mph I could achieve was about 7.16 seconds. I conducted the same test (same road, same warm up drive, same tires, same outside temperature) and did it three times just like before.

7.6 seconds versus 7.16 is almost half a second faster, which is about what I was expecting. HOWEVER, there's one thing that I believe might have held me back. The three times I conducted the test without the chip, my tires were fine. But when I conducted the test with the Racechip, the tires lost traction all three times. I believe that if I had a better tire and wheel setup, I wouldn't have lost traction, and could have potentially got the time down to sub-seven seconds. Let me know what you guys think in the comments, I'm really really curious to hear what you guys say about the loss of traction. Down below I will post the graphs comparing the best accelerations of the three runs with and without line-of-best-fit and the data table. (The plot point 7.16,60 is derived from 1/3rd the difference of 7.01 and 7.48. This will be shown on the bottom of the data sheet in red).

Hey this is really cool data. Half a second is quite an improvement. How does it feel going say 50 and punching it, pre and post chip? I know you won't have data but seat of the pants do you feel more torque? Also, any idea how much hp/torque the DCT transmission can handle?
Thanks for posting this!

I don't have an answer from butt-dyno, but I suppose I could run another test. Do you mean tracking my speed going from about 50-80mph? I could run that test too I suppose, but it'll be a while before I have results since I'll have to find a time (and more importantly a place) to conduct this test safely and ethically. The great thing about a piggyback tune is that I can simply turn it off at will, so I won't have to revert anything back to stock. Also, I should've mentioned before! I have zero other modifications on the car. I will soon get a different exhaust and intake system, but this test was conducted on a completely stock car.

Sorry, I don't understand the question haha! I don't use the tuning chip all the time. I figured if I was running around with better acceleration and throttle response than stock all the time, that I'd be over-working the engine. And that'd be true of any car regardless of whether it had a tune. For example, if you were red-lining your car and slamming the gas pedal to the floor at every green light, you'd have to rebuild your engine way sooner than if you only did that sort of driving on the occasional spirited drive. So fuel consumption isn't really in my list of criteria when determining how good the chip is. Let me know if you disagree though since this is mostly based off of my own intuition.

Here are some baseline performance numbers. Comparing to any of them would be interesting. And yes safe legal place. here in Colorado the speed limit is 75 in a lot of places. so the 49.7 (50) to 74.5 (75) would be intersting. But again, safety first.

Very interesting results, thanks for sharing! I actually also just got a rechechip for my Mini Cooper S 2.0 2016. Did you find it difficult to install? I would like it in a position where it is hidden but also easy to remove in case of need. Did you follow any specific guide on how to install it?

I followed the instructions given in the packaging, but I also followed the video instructions on YouTube. They have installation videos not just for Minis, but for all the cars that they make the Racechip for. However, since I have the base model, I watched the BMW B38 one, since that's the engine I have. I'll share the link below. I didn't find it too difficult, just much longer than I expected. But that's likely due to the fact that it was my first time ever working on a car and I did it myself, so I was learning while doing it too. If I were to do NOW it to a friends Mini, I'd be able to do it much quicker.
