Hi. Recently purchased a cable and software from Blitz Racing. I also have an ECUMate, but RoverGauge is far better at showing a host of ECU signals graphically all at once in real time.
I bought it specifically to investigate idle issues and stalling at junctions on my Chimaera.
The logging facility is particularly useful as you obviously can't keep an eye on the display whilst driving.
However, it can generate a large volume of data which takes a while to interpret / manipulate.
If the RoverGauge software is actively being upgraded / improved a useful feature would be to have the facility to playback a created logged data file and generate the same graphical outputs as captured during the actual logged period using the logged datatime to synchronise the playback. A scroll bar which allowed the user to jump to a specific time, pause the playback, jump backwards etc would also be useful (Windows Media Player like).
My local TVR garage also has RoverGauge (as I'm sure many TVR specialists have) and having this facility would allow me to email them logged data files so they could play them back to see what was happening with the car without having to take it to them at which point she will idle perfectly and not stall !!
