Anyways heres the link: http://unichip.us/Saw it during Car and Driver a few weeks ago. The offer plug and plays for a lot of vechiles, but for the 3 it has to be hard wired in a piggyback.
Here is a quote from their site:Also from what I read from Unichips website it does not void the warrenty. Click the link to their FAQ.
Considering that the chip causes changes to the A/F mapping, the spark timing and other parameters, I'd say that the dealership would have a case regarding engine/tranny warranties.All ECU modifications can void a manufacturer’s warrantee if the modification caused a failure, regardless of what aftermarket ECU manufacturers may claim. If the dealer finds it in the car, and the warranty claim is engine related, the dealer may have a case and may attempt to not honor the claim under warranty. The dealer still has to prove the modification caused the failure.
From what I have heard, it will modify the signals your PCM sends to the engine. It piggybacks on your ECU's own programming and that's why it needs to be hard wired into the circuitboard.Unichip doesn't alter your ECU that I can think of (refer to site) also as with any performance mod yes this one can void a warrenty but it wouldn't void the warrenty unless the dealer could prove it caused the problem just like an intake or something.
