Pros/Cons: Racechip vs. Bootmod3
This would be for an LCI X3 xDrive35i, M sport. Besides the method of implementation, what sets them apart from each other? Is one better than the other, producing better results? Just starting to learn about this and can't decide what to go with.

having owned both, this is not even a fair comparison. bootmod3 is in a league of its own. this is a no-brainer.

I would love to hear some objective differences, more than "its in a league of its own" and the like.
Which one is faster, 0-60? Which one is better for an otherwise stock engine, and why? Which one is better for a modified engine, which mods, and why? Which one has more low end power and torque? Which one has more high end power and torque? Dyno for proof of course. The newest racechip has a bluetooth option so you can change the program on the fly, unlike the original version that had physical switches to change, so it is more user friendly now.

Piggyback systems work by splicing into your car's wiring harness to intercept and manipulate parameters that the ECU sees to generate additional power. There is no configurability other then a few jumpers on the PCB. The biggest con to me, was that this solution did not offer any scalability for mods done to the car. When visiting the dealer you will also have to physically remove this harness or you risk voiding your warranty. On the other hand BM3 is a complete ECU reflash. Instead of manipulating signals from the car's sensors, we are given fully adaptive maps that can compensate properly. Yes, there is a bit more involved with the initial setup. But it's all relatively easy and streamlined. BM3 offers OTS or "off the shelf" maps that are cookie cutter. You don't need to configure a thing, this product is as basic, or as advanced as you would like it to be. You can revert back to stock easily, without having to take anything apart under the hood. This product also holds it's resale value better. The license is transferable to other owners or if you buy another BMW you can transfer the license to that as well. Racechip is specific to your BMW model/engine. Ultimately the BM3 felt faster and smoother to me. I liked the transparency of the product under the hood, and the ease of reverting to stock. I liked the option of using different OTS maps based on which mods I had installed. The RC felt jerky to me. Resulted in several drivetrain malfunction errors and had to reset the car. There was phone support, but i wasn't impressed with it. I hope this helps.

The latest versions of RC has bluetooth/app option that allows for easier customization/different maps. I have an older version of RC and it works great. There might be some hiccups/drivetrain malfunction warnings as the ECU adapts to the altering of signals the RC does depending on the settings, but they tell you to expect that and if they happen, they go away pretty quickly. I havent had any issues with my RC. I dont care about warranty as my X3 is long out of warranty. Is BM3 the more elegant solution? Yes. But I still havent seen any true comparison of the two that says which one is faster for the average driver or comparison of dyno charts which would tell you if one is better at low end torque and the other better at high end hp, etc.

Thanks for the detailed reply, BOSSBMW
Does anyone know what kind of performance numbers you can get with BM3? RC claims 77HP. I can't find anything for BM3 unless it's right under my nose somewhere.... |

I ended up going with BM3 this past weekend. Wow! What a beast it has turned the 35i into! Although, I was surprised to discover that my 2015 (11/2014 build date) had a pneumatic wastegate. I thought 2015 (late '14 builds +) got electronic wastegates?

Absolutely! However, it depends on what you want from your vehicle. If everyday around town driving with the family is your thing, probably not so much. If you like spirited driving, go for it.

I’m confused because in your info....you show Drives: 17 x3 m. I'm assuming that means a 2017 (F25) X3 Msport? If so... you either have N20 (2.0L) of N55 (3.0L). https://en.m.wikipedia.org/wiki/BMW_X3#F25
