I just got trinitiy and did all the updates on the computer and installed per 91 successfully on my truck. But when i either build my own tune or modify the parameters afterwards it gives me the pcm error unable to reflash. Ive returned to stock and tried again but same thing. All i tried to adjust is tire size and throttle boost. It will let me with no issues update and install a performance tune but im unable to adjust any parameters? any one know what to do or had this happen to them thanks

what is the current version? (options/show information)

Not sure what you mean by options. T1000 I updated the latest update to it yesterday the most current one.

Go to options, and then show information (: It will have what he needs there.

Might check your cable, pull it out, make sure there is no dust in the OBDII port etc. Make sure the cable is in securely as well. I am sure you have probably done all this Just throwing it out there.

Ok ill look tonight thanks

we're on 1r09e now, id suggest updating.

Ok will do I did an update 2 days ago to the upper most update but ill try that one instead

Did the update to 1ro9e it still installs the performance tune but this time around I did mpg tune and it successfully installed into my ram but once again I can't change any parameters error reflash -1

Odd, we're looking into it.

What changes are you trying to make exactly?

All I have tried to change is throttle boost and tire size

I have a guess its tire size related, have you tried installing the tune without making any changes?

Ive tried without modify anything and the tune installs fine. but i cant modify tire size or throttle boost before or after i install the tune. i have mpg tune installed right now and if i go back to modify i get error reflash -1. i get the same if i try to build the tune with modified tire size. it would be nice to have my tires are 3 inches bigger then stock im out about 6km/h.

Ok, good deal, we'll get it sorted out.
