So does this prove Tuning Boxes are a poor comparison to a proper ECU map
Interesting video from Darkside Developments highlighting how tuning boxes actually perform verses who they say. Not one of the boxes delivered anywhere near what was advertised DTUK TDi Tuning Race Chip |

So a company that sells remaps says tuning boxes are no good? Strange lol.
I have no experience of either tbh.

Did you watch the video? The way a tuning box delivers its power makes total sense to me and his explanation also makes sense. Interestingly that they did not make the power. My own DTUK box which was on the 530D did deliver what it quoted

I'm sure hes being completely honest but its still a see it for yourself type of thing for me. Its the same when you see videos from tuning box videos, they all seem to show you the figures they state. I'm actually considering getting a racechip from my Xtrail, but without a lot of independent reviews, I'm finding it difficult to go through with it. I know remaps are good, and will be getting one for the 440i, but I dont want to fork out that much for a tip run car lol.

I don't think that there are too many folk who really think a tuning box gives a better performance uplift than a well resolve remap/flash tune, in terms of qualitative (torque cures, smoothness etc) or quantitative measures (peak power, torque).
The benefits of a tuning box are more around cost, in that you can sell a box on, and they tend to be pretty cheap, and also that by removing them you tend to leave much less evidence of a tune ever having been used compared to a remap/flash tune.

Some interesting experiences with BM3 tunes on late 2019/early 2020 B58 TU units over on the X3 G01 forum...
https://x3.xbimmers.com/forums/showt...1648493&page=9 I particularly liked the guy who describes his car as “a $65k brick” |

The chap's comments about traceability are very true. When i took off my DTUK 3Ch box, it had about 10 errors logged against various engine sensor faults.
My car really didn't like it, but it did shift - it felt nearly as quick as a 320BHP remap. Mine eventually started stalling when trying to idle at traffic lights so it had to go! |

Interesting video and he makes some good points regarding rail pressure and injector/DPV longevity.
There are good and bad tuning boxes of course, the same as there are good and bad remaps. |

Coincidentally, I found a used race chip for my Xtrail on ebay yesterday for £60. I thought for that price I'll give it a go, and if its pants, I can sell it on for the same price.

He classes them as good, but they are all manipulating rail pressure which is a blunt instrument that can cause problems later on (injectors, DPF, black smoke). The best tuning boxes (AC Schnitzer and Steinbauer) leave rail pressure static and control fuel injector duration and timing at specific points instead, while monitoring EGT to make sure the increase is being delivered in a safe way. In essence, these are doing the same job as a remap, but using hardware so that your car's software is not affected. I would call these premium, not the brands tested.

I've now had a chance to watch the video. It was a bit of slog! However, the results are interesting... wouldn't touch a Racechip one!
I used a TDI tuning box on my old 330e and it worked pretty well. It didn't quite Dyno what they claimed, but it was a healthy increase and pretty smooth with it. However I know a couple of others who've tried them and didn't like them, had some issues with stutters and lack of smoothness so returned them. One was a petrol and the other a diesel. For me Personally now, after a few years of trying both remaps and boxes I don't think I'd use a box again. I'm happy to remap, with a reputable tuner, but only when I'm prepared to pay to play! If I can't afford to fix it myself then I can't afford to tune it. And if I'm prepared to take that risk then I'm going to tune it properly and make it worthwhile.
