Hello,

I bought a tune from a dealer 6 years ago, and have not attempted to install the tune with my vehicle until just recently. I am receiving code $0536, and have confirmed that my serial and license number for my AutoCal V3 do not match the 'Remote' and 'Master' number in the tune file. It looks like my AutoCal does not have a FlashScan linked to it.

The tuner looks to be out of business and has not gotten back to me to re-send the tune with my AutoCal Serial/License number embedded in it.


What are my options or what am I missing here? Assuming the dealer never gets back to me to send me a link code or 'convert' authorization code, what can I do on my own end?
