Came home from the shop today after having the 4.10's installed pulled in front of the house loaded the new tune and nothing! Car turns over but won't start. Tried my old tune nothing again, disconnected the battery try again nothing, even tried the stock tune and nothing. It appears as if the SCT will delete the tune that is on the PCM but will not load the new one. Any ideas?
Yes xcal2, I will be calling them first thing in the morning or 5:30am pacific time. I just used the damn thing 2 weeks ago with no issues. I was just think maybe someone had the same issus and it ended up being something simple, I need to get it fixed tomorrow I was scheduled for the track Sunday.
mines does the same thing except most of the time i just cant load the new tune itll go untill put the key in the ignition and then read eror.ive notice that it only happens when the car is hot or after stepping on it.just let it cool off a bit and try it againg,it works for me.
