well, the guino is watching the injector so it should not be faked out by open loop(and it does display more than one thing at a time), but john you are ultimately responsible for making it work on your vehicle and may have to do your own research to see if it will work and how to make it work (or who to buy a case of beer for to make it work), the guinos are not consumer items where you can try it and send it back if you don't like it, just fyi.
