2003 Hummer H2

yes it is a old tuner, that i just bought new

i want to say that it has backed up my stock tune, and it shows my VIN # on the predator.

when trying to install teh performance tune tho, i get 2 errors
Required time delay has not expired
&
scripted error
write failed.

yes i have the onstar and radio fueses pulled
key turned on, not accesories

i have even unplugged teh battery in a attempt to see if it would clear it so i could upload.

now what??
besides the obvious of getting a new updated unit.

do you have any other aftermarket items installed in the truck, like aftermarket remote start, alarm, satellite radio, trailer brake, stereo amp, in-dash nav system, etc etc??

you need to also disable/disconnect any of those types of items as well, since they create power draws...

those are usually voltage related errors...

well it turns out i havent actually gotten the onstar fuse pulled.

i folled the instructions in the manual, and pulled a few more additional fuses, but it seems the Onstar fuse is actually the fuse labled "Info" int he fuse box. so, when i get off work tonight ill give it a try and hopefully we can call this good.

thanks for the help btw...
