hello new 16 Limited. is there a tune for me? is it worth it? btw don't have access above 91oct.
I will try v5 this weekend too. I've had a problem with v4 where it will bounce off the rev limiter at the top of 2nd gear a few times before shifting into 3rd... will see if it fixes that.
Per LMS, the V5 is not supposed to be an improved, stronger update. It is meant to address a specific issue (full throttle hesitation). If you do not have this issue, they prefer V4. I did not update mine and stuck with V4
I saw 2 issues with mine using V4 93 or 91 tunes.
1. Full throttle hesitation, but only on the freeway when I kickdown the trans with full throttle to pass (60+ mph).
2. Bounced the rev limiter before shifting to 3rd from a stopped full throttle take off.
After just installing V5 I also installed new plugs gapped at .030". The old plugs still looked good with 20,000 LMS tuned miles on them (tuned at 2,000 miles). Gap did opened a little to .032" on each of the old plugs.
The winter blend fuel may be contributing to these issues, so I may give V4 another try after warmer weather arrives to see if those issues clear up.
The vehicle will never actually allow you to have full control over any stability system. However, that is something that advancetrac still has control over at higher speeds the ECM is far more conservative when high throttle requests are made in conjunction with steering wheel input. That is something that we have addressed with V5, so if you would like to try V5 all we need is a tune update form. That simple.
