Thanks for the links Nate but I didnt want to reply because I did go to these pages months ago doing a search for codes for the Scangauge and it didnt give me explicit info just a list of pages and files, no how-to.
Did a search on Youtube and found one video that may help but still Greek as far as setting codes to get different readings. Too many SG models and my box doesnt tell me which model I have also. Supposedly have to play with it and go to Xgauge feature and program in a bunch of codes in order to get other readings. If this is true, my though is why didnt they just program them in from the get-go. Not sure if this is what is required but if it is, then this will have to pass until I get enough info on the codes I need and how to program them in.
Will try to call the company on this for better understanding. Wondering from comments I hear if the SC is responsible for me not getting any results from the 3 big mods I did on this truck.
Some say it just reads the vehicle info but others think it can change how some devices work.
The jury is out on this hence why I need to call the company.
Im not the only one having trouble understanding the workings of SG. Here are just a few comments on another forum I found doing a search for SG codes and programming.
RE: Scangauge question
Supposedly there's a ST & LT trim option you can set using the xGauge options. I don't know how useful that is.
I can vouch for the fact that changing my MAF mod setting screws up the mileage big time on my SG, more than any other mod I've done.
RE: Scangauge question
I wouldn't use the Scanguage for anything mileage wise except for "relative" purposes. It has been off on my car from the get-go. You cannot see anything happen as the ECU still computes it final results. Even with my AFR meter, I would not know anything but general readings.
RE: Scangauge question
Ive noticed the same as Rick,
To me SG is an invaluable tool when fine tuning of sensors is concerned and the ability to monitor each tweak closely. How anyone can successfully tune sensors without one is totally beyond me. Sure it could be done to some degree, But the possible long term damage to the engine, along with the fact that ECM open/closed status can also be monitored, makes it well worth the cost. The art of fuel economy savings, HHO technology, etc at this moment is all about FINE tune. In order to achieve optimum results you gotta have the proper tool for the job. MPG ive found best to just do the math at fillup.
