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?

sadly call sct tech support.....xcal2 right?

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.

sorry to hear it satown

the only thing i can think of, is if you
have a tune on your pc, transfer
it to your sct and then try flashing
the pcm

let us know how you end up fixing
the problem

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.

It had a P2107 and P2106 error I cleared the error and it still did not take the tune and the P2107 error came back any ideas?
