    99 Jtec question

    So a customer brought me a 99 Ram with a cam and other bolt-ons. So I wrote the ECU once perfect! Now I did some other adjustments to the calibration and I get a "unlicensed vehicle" note on the write box and I won't do nothing after that? Anybody else have encountered this issue??

    Thanks in advance
