2001 ram 1500 5.9 Magnum wont write, "erase aborted"
This seems to be a common issue, but i havent found any solutions to it as of yet. Working on applying a tune to a 2001 ram 1500. Its been fully rebuilt with a comp cam, ported heads, etc. extremely new to the tuning world, so I really dont know what to do.
I can use the beta to scan and read all i want without any issues, but when it comes time to write a file into the ECM, it just automatically says "erase:aborted" and it says "failed" up in the corner on the status.
To note, my truck does run the Jtec pcm, and ive heard that those can be tricky. Also, when i try to look for a "write calibration only" option, there isnt one. theres only "write entire" or "do not write".
any and all help on this would be appreciated. all i know is that it wont flash the ECM correctly due to the fact that it wont erase it to begin with. i even tried re-reading the truck, and writing a "tune" with literally nothing done to it, and it still failed. the battery sits at 12 volts based on the gauge (give or take a tiny bit), and the cable is connected well. no wiring issues that i can see, and it has NOT bricked my ECM.
I'm at a loss, appreciate any input.
also, picking up a few things on the scanner, such as spark retard at 7.5, and 120 degrees and LTFT drops below -11. theres a few other issues im having, hoping a few simple changes is the tuning will fix them though. again, any input is extremely helpful as im very new to this.
