06 chevy tahoe 5.3 wont take a tune

Post by Sl33p3r »

We are using a trinity t1000 on a 06 tahoe 5.3. Originally it was saying the truck had a tune so i called support about it and they told us to have the dealer flash the pcm first so we did that. Then it was still doing the same thing after it was flashed. So then i called in and we updated to gm_j1850 and still only tune options we have on the menu are diablo tune, 87 octane tune, factory hp tune, and original backup. There is no 93 octane tune on the list. Please help i already spent $250ish at the dealer for a reflash. Currently when you try to tune it it tries to backup then says "original backup not saved (-11)." If i hit "more info" it says "pcm:error prepare read (-1)"

Yes, those tune options are correct... "Diablo Tune" is the 91/93 octane tune...

Anything aftermarket installed in the vehicle? i.e did not come from the factory?

You need to make sure anything aftermarket is disconnected/pull the fuse for - anything like aftermarket stereo, subs, amps, nav, alarm, remote start, seat heaters, trailer brake/light setup, etc.. anything like that, their wiring harnesses need to be disconnected/pull the fuses for it before you try to tune anything...

also make sure everything is turned off inside the truck.. lights, radio, heat/fan/blower, do not operate power windows, put your parking brake on, etc...
