Hey all new to this forum. I have few questions. I have replaced 2 engines and 2 ecus in my 05 dodge viper. The first time I paid a guy to come by and recalibrate the ecu and odometer.

He simply brought a laptop with him with some sort of a usb to obd2 cable. (cant remember which one). Next thing you know blink blink all done. all in under 3 minutes.

So this engine swap. I wanted to try to do this my self, but cant seem to figure out which software and cable he used. I currently own and an elm 327 usb interface, Vag k+ can commander 1.4 and the tachpro universal programmer and cant get anything to work. Im not even sure if the milage is stored only in the odo or also in the ecu, last I heard from my local dealer is that its in both, but they have given my stupid answers before

I would greatly appreciate if someone could point me in the right direction.
