We have made a little program called Ptune.
It can be used to see reel time values and it´s not for tuning your engine.
Functions:
You can see the most important values like lambda/afr, rpm, L/km, L/t, also data logging is possible and if the phone has connection to internet it will automatically send data to a server for later use. Data will be stored for too days then automatically deleted.
OS: win mobile 5.0-6.5, xp, vista.
More to come.
If someone have a smart function they would like us to implant, then feel free to write and we will see if it can be made.
