Have not had this before have tuned 50 plus vehicles and for life of me cannot figure out what has happened. Did a complete read licensed vehicle made my changes saved which all went normal. When I attempt to write says it is unlicensed. I verified license information has my vin shows its good. Do I need to do a re read and skip the fuel pump module ? Thanks for any help in advance
Yes.
The fuel pump control module costs 1 more credit. You can also deselect the CCM/FSCM from the calibrations details pages on the file you have.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Doing the re read with fuel module not selected allowed me to write write my tune thanks for the help and hope this may help someone in the future
