I have an EGT sensor in there, but it's from the Banks Six-Gun. The guy had it installed b/c he had the IQ in there, but took it out before he gave it to the dealer he sold it to. Will that work? And I'll just get a fuel PSI sensor if I have to. So what does this app work with? The bluetooth and other things like scangauge? Is that how you are running your app? I am clueless when it comes to these gauges.
