We have a 2000 f350 7.3 Super Duty. We are trying to use it on a Iphone 4 with Torgue Pro and an IdeaPro WIFI OBD II Diag Scanner. We have down loaded the Ford PIDs and they are on the phone ready to use. The scanner works but we have no feedback other than RPM and we get a warning that this truck does not supportHP/... and a string of info. It also causes a check engine light when we try to use it to reviews any possible codes. We then down loaded the software for Ideapro for Iphone and the minute we activate it it shuts off the truck and it wont start - not good. Does anyone using the Torgue PRO, IPhone 4 or later and the 2000 f350 have a WIFI scanner that will work for them. We are wondering if the WIFI scanner is not compatable for some reason of if the trucks computer or is just to old for a more modern plug in device. If you do have a combination that works we would love to know what it is.
