Hello guy's,went and purchased a ST3 self tuning device from ChippedUK only to find that the device would not communicate with the ECU,to cut a long story short I drove 130 mile's to ChippedUK's head quarter's to let them see if they could get it to work,Jayson and his lad's spent 2 hr's on it trying everything only to fail at trying to get it sorted,top lad's never even charged me a penny for over 2hr's of hard work,they also told me that I should get it reset by my Revo dealer to complete 100% stock only then would I be able to use the ST3,is this because Revo don't want anybody tampering with their files so have put some sort of protection on it? More worrying though was none of the equipment they had(which was more than a VW dealer would have!)would write anything to the ECU and I was told it had Revo stamped all over it,so if my local VW dealer had to do any software upgrade's they would have been unable to do so,hopefully the Revo dealer will have my original stock map and be able to put this back on,I don't mind paying for it even thogh I had paid nearly £750 inc the SP1 switch.Any Revo authorised dealer's have any comment's on this.
