Come on guys (and Gals!) think about this seriously. /ubbthreads/images/graemlins/goofy.gif You have a 5hr trial. It takes 30 minutes to set up and reprogram the ECU (30 minutes people!). As far as I know ( and correct me if I am wrong) that's the last the tuner sees of your car. So you drive around for 5hrs using the well tried and tested REVO settings - which all seem happy with (which is fine & not in dispute). But what happens when the trial ends? Are you seriously telling me there's enough room and computing facilities on the ECU to reset itself to factory standard at the end of the 5hrs??? I think not. /ubbthreads/images/graemlins/cry.gif What seems much more plausible is that the ECU is some how limited ie. a torque limiter. After all I don't believe the car shuts down and reprograms itself (which I am assuming would take another 30 mins) so how does it suddenly go back to factory settings? Again this is my opinion and view only and I have only common sense to back me up.
