Today, I've bricked my first PCM ... playing with ETC parameters ... (alternate mode and others stuff)
2005 chevy avalanche
My question is : Can a tech2 unbrick the pcm (loading the default tune?) or I have to buy a new pcm.
GM french stealership ask me about $150 (for just trying), it's the price of a new one PCM ... but I have to wait 1 week (living in France).
