hey guys trying to make some tweaks to an '08 Silvy with a Radix 1900. its got the magnuson tune in it. the shift times are pretty damn slow IMO, and i'm trying to quicken them up a bit, but i can't find where exactly to do that. first time to look at an '08 calibration and its quite different than mine. the older ECMs such as mine has the Desired Shift Time at Trans>Shift Properties>Desired Shift Time, but not for the '08. any ideas on what params to adjust to quicken up the shifts? thanks guys

 

bump up for the day crew...

 

The 2007+ have desired shift times as well, just sounds like your software needs to be updated (or HPT hasn't added that in for you yet).

 

Hmm...I didn't see them where they normally are...I have HPT 2.22. I may have to contact HPT support.

 

Been able to adjust shift times with EFILive for a couple of years now on the 2007 and newer, I'm not sure about what version you'll need with HPT though.

 

Appreciate you responding. I posted up on HPT. Hopefully someone will respond.

 

While we're talking shift times, what's a good area to be in for shift times? I've heard you shouldn't just zero out the table like I've heard some people doing, but never heard what would be the minimum time that would be considered safe. I've got a 2007 4L80 + TransGo

 

In order to view the desired shift times,you will need to email support at hptuners to get the latest beta 2.23.If you send them an email,they will post the latest beta on your customer login page!!

 

Shoot us an email, I'm pretty sure 2.22 has these but if not I know the beta software does so we'll get you fixed up either way.
