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

But regarding the question of which tuners guarantee to deliver more meaningful/better software than a well-designed power box, unfortunately, this doesn't help us at all .

Hi,

A power box can never be specifically tuned for a particular car because there are always tolerances in the engines, and every mass-produced engine reacts slightly differently to performance enhancements.

Therefore, you have to drive the car, adjust settings, test, drive again, etc., until it's right , and thus make fine adjustments – only then is the software specifically tuned for that particular car. Everything else are mass-produced chips that are only roughly adjusted.

So, my tuner assured me that he can achieve a much better and more precise result if he modifies the original engine control unit (ECU).

DJ.

Name and address?

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