If your refering to my piggy back ( which I'm sure you are since I'm the only one with one that I know of ), I have absolutely nothing to hide or not share. I have talked to and tried to help dozens of people on this forum both on the forum and offline. I have had 15 + crossfires in my personal shop on several occasions working on their cars for FREE,just because I love these cars and most of these people ( not like that though) Maybe just ask me or pm me before assuming that i have secrets.My main computer has a Chip socket with some inmotion custom chips. I have 6 tunes that I can swap out, 87oct,93oct,100+oct,nitrous small shot,nitrous big shot, and the stock chip. My piggy back is pretty simple in theory and I can only vary fuel mixture, have never found a way to control anything else outside of that ie. timing . The ecu's on these cars just can't be completely overridden from my research, once you trick it,it will take it back,flip it, pull it, and if it's confused, go into limp mode. Thats why in my sig I put " small piggy back " It is connected to the map,tps,ecu and runs through a AEM tach adapter then a FJO proggresive controller that interupts signals and applys ground under certain conditions. I did not design or install by myself, so I'm not sure if I understand everything completely myself, I paid a lot of cash to a pure race shop to help me get this far with it and it's far from perfected,But I can make a 1/4 mile pass with or without n2o and not run lean. See ya and thanks for all the input, we all have a lot to learn about this car, and with all of these great minds maybe we can crack this computer someday ? !
