Hi,
so, car is already tuned,
cannot read the tune (no VIN and not able to read) probably because tuned with other tools than HPT,
dealer not able to tell/don't want to tell about previous owner, and probably the tuner was in US and the car is now here, in Europe,
i tried some options with HPT support, only way seems to be back to stock with original tools (so, impossible for me).

I was plan to find a stock HTP file from 99 Viper and erase the "bad" (aka, w/o VIN and not able to be read by HPT) existant file, but
1) as the PCM is already tunned, by other tools than HPT, should i try to write entire from a repositiy viper 99 stock tune ? (HPT support speak about OS, and risk to fried PCM)
2) as i know it exist some SKIM issue cause of VIN or other stuff, should be able to start with another tune then the (lost) original one ?

Don't care about VIN, just want to tune this car (and prefer not crash a 2400$ PCM :-( )

HPT speak about WITECH tool, but don't know about this hard/soft, don't know a shop who have this in Europe...

Any option/info/idea for me ?

Best regards
