Default Ask Tadge Poll: Ending 26 June, 2016

Folks -

This one is going to run a little differently because of the annual GM shutdown. We'll run this for a week (ending next Sunday) like usual, but I'm not going to send Tadge the question until 10 July. That will allow us to skip an entire cycle and let Tadge and crew focus on the re-start.

The questions are posted in the replies below, with links to their respective threads.

Default The relationship of "Racecar to Streetcar" within Corvette

Original question is here.

RC000E asked:
Since Corvette/Chevrolet's direct involvement in ALMS beginning in 1999, could you describe the evolution/intensity/milestones of the relationship between the racing side of the Corvette and the factory side? We've seen multiple facets of the program have been transferred in house, from the engines (formerly Katech) to the frames of the C7.R being built in house, etc. Has the racing sides influence increased exponentially with time would you say, and as chief engineer, how critical do you feel the racing teams involvement is to the future of Corvette as a brand? If at all possible, some words from Doug Fehan as well, on this subject, would be fantastic!

Default No water temp pocket gauge for Z06

Original question is here.

jcthorne asked:
The instrument cluster in the Z06 will not allow engine water temp to be displayed as a pocket gauge. It is displayed as a numeric value in the tour mode info display but not available in sport or track at all.

I understand the base model has a physical water temp gauge where the Z06 boost gauge is so the choice made some sense for the base model but would really like to be able to have water temp as a pocket gauge in sport mode in my Z06.

Any way this could be added as a software update for the instrument cluster?

Default PDR Pre-Record Button

Original question is here.

slickstick asked:
While the PDR is cool for the track, it would be nice if it had a street mode as well. It could be set to record constantly, and add a recording 'hotkey' to the infotainment home screen. If anything noteworthy happens on the streets, pushing the record button would instantly enter record mode, and with a configurable pre-record (ex: 30-60 seconds) would capture what happened prior to the button push.

Can this feature we added via software update? It seems very simple and straightforward to provide owners.

Default Introduce the Corvette Engineering Team

Original question is here.

jvp asked:
Would you be willing to introduce us to the team of engineers and others that work on the Corvette? I'm curious as to how many folks are directly tied to the Corvette.

Default Melting AFM Actuators

Original question is here.

Along4theRide asked:
I hope you can clear up some questions about the AFM system and the use of plastic AFM Actuators. Some of us who purchased Z51 cars specifically to track the vehicle are disappointed that under heavy track load and temperatures the AFM actuators melt and fail. Besides throwing a check engine light and horrible noises during V4 ECO mode, could you explain what issues someone might have in just running these in this condition? What is GM’s position on replacing these? It’s my understanding from speaking to other affected users (some whom have had the AFM actuators replaced 5 times) that there is no fix for this condition. Is there a new part design coming soon for this? I’ve heard that Spring Mountain has seen this as well and it affects many of their vehicles. Can you offer advise to those affected? How do we fix this issue permanently?
