NQbbe Posted July 25, 2014 Share Posted July 25, 2014 I just checked ETIS for my car, and it says an update is available for the powertrain control module (PCM) - does anyone know what these kind of updates contain ? Or in other words: Is it worth it to go to a garage and get the update ? Quote Link to comment Share on other sites More sharing options...
alexp999 Posted July 25, 2014 Share Posted July 25, 2014 PCM is Ford's name for the ECU. It greatly improved the drive-ability of my car when I had one done. The problem is Ford will not do it unless they are fixing a problem or you are paying them for the privilege. Quote Link to comment Share on other sites More sharing options...
NQbbe Posted July 25, 2014 Author Share Posted July 25, 2014 alexp999: How did it improve the drive-ability ? (for instance turbo lag, low-end torque or similar?) The reason I'm considering getting it done, is because of turbo lag - but of course there's no guarantee it'll change that. Quote Link to comment Share on other sites More sharing options...
alexp999 Posted July 25, 2014 Share Posted July 25, 2014 Increased and stabilised throttle response. Totally different engine though. I was pretty unhappy with how unpredictably the car drove and when I saw a pcm update for the car spoke to ford about it and they agreed to do it under warranty. I was having issues with getting either too much power or not enough, pretty dangerous trying to cross a busy a road and the car decides to give you no power.

NQbbe Posted July 25, 2014 Author Share Posted July 25, 2014 Yeah I can see how that should get covered by warranty - my "issue" probably won't. And I agree it's very dangerous to drive with unpredictable power. Quote Link to comment Share on other sites More sharing options...
