Tunerpro 4.13, 4.14free

Post by rsicard »

Trying to use 4.13 and 4.14 free. With 4.13 get a message before it loads "Unable to extract IO.SYS. Log in as a user who has such permission." Once in 4.13 am able to read bin file from chip mounted on Moates APU1. Unable to do this with 4.14 free. This is with just the APU1, USB cable and computer running 4.13. Am a newbie at this thing but has used 4.13 several years ago on a 1994 7.4L (454) with limited success. Need as much help as I can get to be able to get a baseline tune on my 1995 GM C1500 5.7L Pickup. Trying to learn to get gauges up on 4.1x and datalogging. Sure would like to understand Tunerpro much better than now.

HELP!

Yeah, that was a known problem, there was a solution posted for it back when V4 was still current. Try searching for that on the forum.

Why not switch to V5?
