First time using the autocal. This is on a 2010 6 speed silverado. I did the data log (about 25 min, that's what the tuner suggested) then I went to read1 (e38 engine file) and selected it. It did its thing then said ignition off then wait 15 seconds then done. I then went to read 2(t43 the transmission file) and selected it and it says file system full then error 0520. I tried unplugging it and got the same results. Any ideas?

 

This will explain it.

"File Sys FULL!" followed by "ERROR: $0520"

 

How do you delete just the data log info? I already have that file saved on my computer so I was gonna try to delete it and see if there is enought room. I dont have the autocal here i mailed it to my sister to get the info i needed to tune her husbands truck as a surprise when he gets back from over seas. ive never used an autocal and i need to be able to tell her what to do. Thanks

 

Plug it in and hit delete scan files. I've had to do it twice on some occasions.

 

Plug it into the truck correct?

 

Yeah give that a shot.

 

Deleted the data log and I was able to do both read files.
