Was looking around on the apps store of my Iphone and saw this app and was wondering if this thing will work like the scan gauge II check it out let me know what you think!

Most likely be the same as the SGII... Just remember either way you can only get information from sensors that are present for the ECM. So it might be possible that OT-2 might be able to exceed SGII by giving timing, VP44 info, etc...

as an obd2 scan tool(my opinion) you probably will not get anything that the scan gauge gives you. most obd2 stuff has to do with gassers and emissions. on my 99 ram, only a few things could be monitored. its because even though the ECM might be monitoring the sensor, your device can only ask for generic obd2 PIDs. http://en.wikipedia.org/wiki/OBD-II_PIDs you may have better result as a newer ECM would have newer software and more registered PIDs this is most of the things i could monitor(for now ) the more PIDs in monitored, the slower the refreshes were. http://forum.mopar1973man.com/showthread.php/1275-data-from-my-drive-on-the-highway to monitor EVERYTHING you need a chrysler DRB-III

Oh thank You GuessWho! That was exactly what I needed now I got all the information for correcting the SGII display of a few problems. Like MAP sensor I can now write a XGauge that is corrected... Also found a few other entries that are cool like... * Number of warmup cycles since codes cleared. * Distance travel since code cleared. Those are going to be handy to add to the SGII... So here is the programming and the current XGauge list... http://www.scangauge.com/support/pdfs/XGAUGE.pdf http://www.scangauge.com/support/pdfs/XGaugeCoding.pdf

i would be interested in seeing how many PIDs you can get data from. most of them return nothing(on my 99's ) i would imagine that a newer truck has more PIDs that are usedon the wiki link, read the part about non-standard PIDs
