Had my 2013 3.2 Auto Mazda in on Monday for its 75 000 service. They updated my PCM (without me asking) but what a difference it has made.

It actually feels like my driving a 147kw car now. The whole vehicle just feels more urgent, it actually feels like you driving in sports mode the whole time. I'v reset the fuel trip computer and its showing 0.2 l/100 less but that still needs to be confirmed after a tank or 3.

My advice is if you haven't had your PCM updated on the Mazda for a while, go and do it.
