2014 Silverado hard shift tune

Could you please go into the logging menu and restore default pids and try the log again. This one is corrupt.

Does that mean I have to record a new log or just restore the pids and download again?

you have to restore the default PID's and then you have to record a new log...

Ok thanks.

Try this one. The shifting is through the entire log at normal throttle. It's not on this log but I did a WOT run and the 1-2 was light, the others were firm.

Well I can't really see what's going on if you didn't log the issue....But load this tune the ecm and let me know how it goes.

I only logged the normal driving problem because it bugs me when I'm driving around at normal speeds and everytime it shifts from 1st to 2nd it throws me forward then back... That is the problem and I did record it. Just wanted to let you also know it's not firm at WOT but I'm not worried about it until the low speed is right.

Thanks for the help so far,
Jack

well the tool doesn't log any tranny stuff, so nothing to see in the data log as far as shifting goes..

Well I didn't know..... Zach asked me to log so he could see what the problem might be. I just assumed it logged the shifting.

Have you loaded up the latest pcm tune I posted last week?

Sorry Zach,
Yes and I didn't notice much. When it shifts it shifts quick but it's just delayed 1-2 and 2-3 most of the time. It almost feels like the fuel cuts out and the truck slows for a second then back to normal when it shifts.

I just installed a diablo trinity this weekend and I'm having the same issues with my canned tunes, I am using 87 tune with firm shifts with 15% throttle boost. My 2-3rd has a lag and then a clunk/thud. 1st - 2nd does it as well but not as bad.

I am new to the forum and I'm wondering if there is somewhere I can download the latest "Beta" tunes that you guys are working on?

That youtube video is perfect. I see he is hitting 6000rpm though, I'm not sure how great that would be for the truck.

Wow sarah! That's how I would like mine to shift at WOT. It's better than it was but not like that.
2-3 will bark the tires but 1-2 is weak.
