Hello everybody,
I am coming back to my subject after 6 months full of experiences!
In July I traveled in Germany and installed NBT retrofit at my car. I did it at BIMMER TUNING in Bonn and I have been fully satisfied - the NBT works perfectly!
BIMMER TUNING is also doing remaps for engine upgrade.
The man who installed my NBT advised me to prefer remapping to chip tuning - he said that chips may cause serious electric problems, which can even reach engine failure, according to customers of BIMMER TUNING. On the contrary, he said, he's got many customers that preferred remapping and have driven many thousands of kilometers with no problems so far.
Although BIMMER TUNING's service was great for my NBT upgrade, my trip plans had already included a chip-tuning test, just a few kilometers away from them.
I had already arranged a test with DTE Chip Tuning at Recklinghausen, Germany.
They said they would install a Chip, appropriate for my car model with no commitments to buy! Fair enough! And so they did - I visited them, they installed their chip and then we driven in the neighborhood, in order for me to decide. My decision came out easily: no serious difference was felt in my cars pedal and so I kindly denied the purchase. Also importantly, I didn't like at all, all these cables coming in and out of my engine! - All these chips are said to be "easy installing", but I realized that you have to be an expert to do these plugs inside the engine!
Besides the chip, we also tested the "PedalBox" which was plugged MUCH easier to the accelerator of the car. The Pedalbox showed immediately its presence and so I decided to buy it. The PedalBox increases significantly the accelerator's sensitivity to the push of the foot. But does not increase the power of the engine in any aspect. It just increases the reaction in soft pushes of the pedal. For F30 owners it's easy to describe it: when you choose the Sport Mode in the car, you feel the increased pedal/engine sensitivity - well, it's exactly the same, maybe in a higher sense!
In the beginning it felt as if I upgraded my engine, but it was just the sensitivity and nothing more. The fuel consumption increased as well!
And all above conclude my summer upgrades!
Later, in October 2017, I decided to remap my engine, after persistent research between F30 owners that had already done it and also between BMW authorized service garages!
All answers collected supported my intention to do it!
Owners said they were too happy and met no problems, while BMW’s manager of the garage also admitted that statistically no cases have appeared for such problems! One of them even told me that BMW programs differently its (identical?) diesel two litter engines, in order to market the car for different segments of tax payers in Germany.
So, I proceeded with my remap in a local garage in Athens, well known for good results in BMW’s and perfect feedback. The car is now counting 5.000 km with no problems, while I just had my 50.000 km service and no bad notes came out of BMW’s authorized service garage.
My car was metered at 147Hp/318Nm before and 190Hp/420Nm after remapping the engine.
My feeling? The car was significantly upgraded! The feeling is totally different and you can feel it instantly! It definitely delivers more power in all engine rounds! I am just (even) more careful when the engine is cold – I don’t push it before I see the temperature reached the center of the meter (100o C).
And that’s all folks!
