I am trying to upgrade OS the zf6 to a dsp 5 and it is not showing any options to do this?

I've downloaded other tunes and don't have that issue, what am I doing wrong?

 

[sweetdiesel]

Can anyone try and make this dsp 5?

 

[LarryJewell]

what tune file to you want dsp5, post it up and i'll try it

Thanks Larry, it's the zf6 ECM tune... The top of the list of the tunes that Cindy posted.

The lower 2 tunes are tcm




If you can dsp that tune then it's just my software or me


Thanks again

Table C1803 is out of range, I tried copying a good table in, but still shows out of range. My thinking is if you can get this table back into range then the dsp upgrade will be available. It is unavailable in my software right now too

Common issue on 01s...... change it to the max limit - 0.1 and that gets rid of the issue


Thanks again larry

I pasted the out of range table C1803 into another stock LB7 tune and its not out of range there, is this ecm tune file Cindy posted possibly curropted

No it's just a 01 file ....... Lots of history on this 01 amd that you can't make them fast because of this table...... It's all bs, as this table doesn't do squat

2001 OS # 9393838 is not supported as a DSP upgrade, every other OS is.

From memory this was the very first OS used on the Duramax, and it has had a tendency to do some odd stuff. Most customers shy away from this OS, and as such we never offered DSP support for it.

Cheers
Cindy

Do you happen to have any other zf6 stock tunes that I can dsp?

01 or 02 is fine.


Thanks for the info
