2010 Camaro re-install tune Doesn't work!

Michael_Js · Post by **Michael_Js** » Mon Mar 07, 2011 4:45 pm

Good day. I have had one of Lew's tunes( running on my 2010 Camaro SS manual since July - no issues. I had to bring the car in for a PDIM software update today 3/7/11) to the dealer, So, yesterday I reinstalled the original tune - no issues. When I connected the Trinity to my computer, it did a very long update. I set the Trinity back to my car, then today, went to put back your tune. I get a PCM read error (-12) then a -1 (I think) indicating the original tune could not be read. One of the reasons it said that the tune might be modified. I know I just reinstalled the original yesterday so that can't be the issue. I'm sure it was a major Trinity update as I noticed all the images were different. Other than that, the Trinity has not been connected to the car since last July.

Any thoughts??

Thanks,
Michael J.

Didn't work Mike! I downloaded the update, updated the tool, and entered my car type. Went to the car and same error: PCM: cannot prepare to read (-1) error...

Nothing looks different!

hey there mike.... after sitting a bit, the ecm goes to "sleep" and you won't be able to access it... did you start up your car for a minute first, before you tried flashing it?? doing that wakes up the ecm and it's ready to go...

has happened to me with my own car once... ONCE... . LOL

I got the same problem after I updated my trinity to 1r08. Talked to a guy on the phone, said something like they knew about it and I should be expecting an update that will fix it. I hope the update comes in soon. Anybody know when?
