So,

Im wondering if any of you have any Horror stories with Clone Tools? If so please share.

I am trying to convince a partner tuner to not use clones but rather slaves.

The problem with clones is that CMD and Byteshooter are constantly updating the protocols.
So besides the update we see at the news section they are improving their product the whole time.

Damaging an ecu is in the end more expensive. Buying clone tools will be more expensive in the long run.

No horror stories as such, but the thought of having my tools replaced with cheap enclosures with misaligned cutouts, cables that fray by the connector, 'hand soldered with basic soldering equipment' pcb's and buggy protocols that will never be fixed would give me a fright!

Buying genuine isn't actually that expensive, I know it's a hell of an outlay but anyone who takes chiptuning seriously will make it back relatively easily, whether it be in what they learn from use of the tool privately for by commercial activity.
