Tune Settings?
My car goes to the shop next month for heads/cam/intake (Stage 2 heads and cam).
2009 Z06.
RPM Limiter - 7200 rpms
Turn off Daytime Running Lights
Speed Limiter Off
Fan Control Settings to come on early to keep things at 185° F.
Anything else that needs to be turned off? Turned on? that I should inform my tuner at the shop?
I am just trying to cover all my bases here.

I already installed the CAGS Eliminator this morning. So too late on that.
I just didn't know if there was anything else special that needed to be turned off.

Depends on your goals. You can turn off lots of stuff, but do you want to?
Not aware of a "speed limiter" on the Z06's. (Other than thrust equalling drag, that is.)
Have your fan percentages triggered at lower temps?
Request that you want a smooth transition from "on-off-back on" the throttle. This reduces that "springy" feeling you get in turns.
Enjoy your cammed car.

you can't do anything about the DRL's... those have nothing at all to do with the ECM... those would be part of the BCM - body control module - which tuning software cannot access or do anything to...
Only dealer-level scan tools/software could access that, but a dealer won't do anything either, since DRL's are a federally mandated safety thing...

When you get any cam your car will require a tune. Not for chop but for proper air/fuel mixture and driving characteristics. The chop comes by nature with an aggressive cam and the tune doesn't cause it.
When I say you can fake a chop, I am referring to not changing the cam at all and changing some timing settings to give you a "chop" as if you had an actual aggressive cam. Idle adaptive spark control overspeed/underspeed can be abused to make your car "chop" as if you had a cam. it's silly, but it can be done. I also think it's silly that people spend so much money on a cam swap chasing "chop" so they can post videos of their car idling

I suggest you should do alot more research as this statement just quite the lack of understanding on performance items and how they work with cause / effect.
As stated, "Ghost Cams" via tunes are one of the top dumbest things to ever be done and would be on same level as alot of the Newer SEMA builds.
