Does it bother anyone that it will be extremely difficult to tune if not impossible ?
Most vette owners love to mod their cars
Headers, CAI heads / cam list goes on...

 

How do you know this?

 

I thought I read that it'll have a built-in wideband that will allow the PCM to adjust for most modifications.

 

well if thats the case then

 

maybe most you know, or most on mod forums, but I don't think or believe that most overall vette owners tune their cars. good proportion I'm sure..

plus you don't know how hard it is yet, car isn't out, tuners don't have them.

Maybe GM is going down the Apple road and you will be able to tune but gotta certify parts with GM?

 

Gentlemen and ladies,

Do you honestly think GM is going to leave tuners like Lingenfelter, Callaway, Hennessey et al. swinging in the breeze? And do you think that GM is going to shutter their Performance Parts operation?
Not gonna do it. There's always a back door because racing is soooooo important for the marque. There's a thread on the C7 forum here discussing the C7 PCM and that its "self-tuning". I showed this to someone at Chevy who did and is doing the Open Loop calibration for the C7. He is the real deal. Here's a post from a different site:

That guy is lost badly. All PCMs are "self-tuning". It's been around since EFI. Thats what the sensors are for. They read temps, psi, flows and then the "self-tuning" PCM calulates optimum conditions and controls the engine accordingly. Keep in mind, controllers are cal'd for original OEM HW. That said, if the HW change/mod is to radical, then the SW/cal might be out of it's range. It's all a system, 1 change on the engine now a days has potential for a profound effect to performance, FE and drivability. That effect can be negative or positive. Making mods definately needs to be handled appropriately and professionally on today's vehicles. A lot of controller sw/cals have models in them. They still require HW config input. Changing HW without changing the model and recalibrating could make less power or more power. Without the right tools and knowledge it's a risk and gamble. Take the Cat for example, Not a single OEM in the world puts a TC on their Cats. Yet, you can be rest assured the engine controller has thermal analysis/monitoring for the Cats and other exhaust components. How then, by modeling from CFD, computer simulation, dyno testing and then vehicle calibration. Changing exhaust components without correctly modifying the model to compensate can yield a result of more HP, OR even less HP.

Also, thank about this. If any OEM had a self-tuning PCM, then why would GM or anybody else waste so much time (1year) and $ on design simulation and dyno analysis and another year of vehicle calibration? If the PCM self tunes then build the engine, put the parts on, run the engine so it self tunes and ship it, right? NO!

99.9% of what he posted is garbage. The only accurate info is the LT1 data and some of it is wrong. I wish I could tell you the correct stuff but I CAN'T. If I did I would get fired. I love my job too much to do that. Go to Chevrolet.com for LT1 and Z51 Stingray details. Surprisingly, GM has released a lot of detail on the GenV technology."

 

I can tell you this..the more things they control electronically the more difficult it is to make it hackproof. There are some very smart and capable individuals out there that with time can crack just about anything. PS3 was hacked for a month and now cell phones are getting hacked.


Video games get hacked constantly..fact is for every smart guy making it unhackable theres at least one thats just as capable at cracking the code.

 

I would say most don't tune their cars. Exhaust maybe. Most people would be hard pressed to tear open their motor.
