OBDII programs
OBDII programs
(OP)
Are there any available to use PC's, to interface with the ECM, that will do everything from reading codes, and live data, freeze frames to altering functions ie. operating such things as ICS motors, fan, ignition timing, pulse width of injectors, egr etc.
I did the search deal on here and got nothing. And did the google thing, and see allot of just "readers". Sure would appreciate some ideas. And thanks ahead of time.

The latter chip can be replaced by a suitable PC, allowing you to recalibrate the engine while it is running. There's no particular reason why the strategy chip couldn't be emulated, but when I was doing calibration it was not done that way.
Of course modern laptops are much faster now, and I don't get the impression that clock speeds on engine management computers have increased at the same rate. So if it wasn't practical 10 years ago it might well be now.
However, the OEM gets no advantage from letting end users poke around in the chips, so why would they make it easy to modify the strategy or the calibration?
I doubt you'd be able to overwrite the built in processor using the OBDII, but you can certainly use it to read stuff.
