Just flashed the ecu about to take it for a spin now, while it was writing the ecu it had 'PSM failure' on the dash, it went as soon as the write finished and hasn't come back, just wondering if anyone else encountered this?

I turned the dash back on, no error msg's, just want to make sure it's all ok. Have asked the tuner this question Im sure they will get back to me tomorrow.

Oh and the front radiator fans were at 100% while it was writing, it was amazing never heard them before, they are very powerful it was like a tornado around the front wheels.

just watching this getting in the mood -

 

my experience with fvd. all is well.

 

Yep just took it for a spirited drive - the psm definitely works!

 

That error always comes whenever the battery gets disconnected. It goes away after a few miles. If it does not recur, I would not worry about it.
