aaddzz123 Posted August 12, 2014 Share Posted August 12, 2014 A lot of people are mistaken to believe that you can just slap another ecu on your car and it will run fine... I ran a ks rom ecu on my old gt for a while before it blew up and with that it used to be extremely sluggish down low and then judder at about 3k then pull like a dream... The ecu were designed to remove all restrictions and offer a more aggressive map however you still need to put it on a rolling road with a fpr and have the fuelling set up the best that you can. Personally I'd recommend putting a piggyback ecu on instead and mapping it properly. It'll cost about the same and be a lot more accurate/safe. Quote Link to post Share on other sites
ash p Posted August 12, 2014 Author Share Posted August 12, 2014 I might put it on a rolling road then and see if I can get it set up right I had a fpr but people on here said I should take it off as the jam ecu only works with the stock fpr Quote Link to post Share on other sites
