Reading on the forums more? I can not, one thing is clear: the terror of the chip-tuner, that can? only work in serial mode ? the block of the procedure during the writing of data to the ecu.

Knowing little of the theory and, unfortunately, least of all to practice, I would like to gather some opinion to share here, by one who really knows and it works for real.

1).
How much ? real and frequante this situation ?

2)
Concerns typically beginners, why? not consocono well yet the mode? approach and venture unwary (see the work without the boost on the battery, with a voltage that if cala goodbye) ? And so it is a problem related to the method ?

3).
It only happens why? you use interfaces cloned and therefore not reliable or PC sgangerati ? (and the professional people flow into, using the kit of the brand in thousands of euro, this problem does not want to meet him ?)
And so it is a problem related to the equipment ?

4).
It is a fact of bad luck ?
(okay, this slips always, for? not ? a scientific parameter measurable - let...)

Clarity on the subject block of the ecu (which for a non-professional, if it happens, it results in the immobilisation of the vehicle with trouble resulting not recently) it seems to me relevant.
What do you think ?
