ECM VIN Programming

Hey TW,

I just received a new ECM, from 05Taco4x4 (Huge thank you by the way), and I read somewhere that in order for it to work I need to program my VIN into the unit. Any suggestions on how to do that without wiping the device; the ECM has been tuned by OVTune and I don't what it to lose anything they did. I've also read that it's a simple plug-and-play unit and to just proceed with a normal driving cycle for the ECM to re-calibrate; so not sure what to do. Everything I find trying to search for this topic is very vague. For reference I have a '06 Prerunner 2.7 5-Speed Manual. Any help would be greatly appreciated.

Thanks all
