No idea if it's any good. A chip upgrade that connects to the OBD wiring.

Interestingly it's only US$90 (about £60) plus shipping.

They list models depending on i30 manufacture year.

I wont be trying it, as i'm too old for upgrades

i wonder if it really does work the installation looked a bit rough

Would have been better to wire into an OBD plug, if possible.
