DVT acting up - Scan tool not cooperating with diagnosis lately

[Boost]

So it's getting pretty annoying that I haven't figured out how to use the output and other diagnostic controls in the Scan Tool. I really need to get this working. The other day in a '10 Camaro SS I was connected through the E38 and was unable to control idle and was getting error messages in red (no reply / dvt error something like that). Then today, in an '09 Silverado 4.3 I was getting the same error messages attempting to do and idle re-learn or any other diagnostic control in ST for that matter. I was connected correctly, what gives????? Do I have to validate any modules or something? I didn't think so. Thanks!

Which V7 and V8 software builds do you have...?

[ V8 includes firmware ]

I thought of that. I have the one before the latest, plan on upgrading soon. I'll post exactly which version I have in a few hours. Thank you.

Ok so I have build 139 of V7 S&T, and build 127 of V8. I know a little behind... but is this the cause of my troubles? I will update soon! Do you also need me to hook up the FS to see firmware? I updated that the same time I installed those builds. If I recall, it didn't change. Thank you Joe!

Goto here and install V7.5.6.157 and V8.2.1.151.

Then using V8 EE, flash V2 with firmware 2.07.09.

Will do, thanks! Then I'll check again and report my findings.

It is not release dependant, DVT has not worked reliably for a long time on E38.
Keep on meaning to send a long list of DVT errors to support

A-ha! I think you are right because I have used DVT fine before on other controllers with way older versions. The E38 is a very important brain, can we maybe do something about this?

To my knowledge we are not aware of any outstanding issues related to DVT controls on E67/E38 (or other controllers actually). I have just tried activating DVT on a bench E38 and it acts like I'd expect (given no vehicle). If there are issues please do let us know the specifics.

Andrew , re DVT controls - any issues with E39??
