Hilfe...wer weiß wohin mit dem schwarzen Kabel - Küberl Chip | Posts 16+

But regarding the question of which guarantees more meaningful/better software than a well-designed powerbox, this unfortunately doesn't help us at all

Hi,

A Powerbox can never be perfectly tuned to a specific car, because there are always tolerances in the engines, and every mass-produced engine reacts slightly differently to power increases.

Therefore, one must drive, adjust, test, and repeat until it works , and thus perform fine-tuning - only then is the software specifically tailored to the car. Everything else is mass-produced chips, which are only approximately matched.

So, my tuner has assured me that he can achieve a much better and more accurate result if he modifies the original ECU.

By the way - regarding my first question: I have finally received a concrete answer: the black cable really belongs to the ignition positive. Therefore, it's better to trust the manufacturer
