I just did a quick search and came up empty.. Are there any performance modifications available for the new CTS yet? Any planned? What have you heard? Do you think there will be any turbos or superchargers to choose from? Intake, exhaust?

I'm guessing that most people who buy the non-V CTS would be less willing to lose their warranty with modifications than someone buying a V might be... Any thoughts?

If this has already been discussed, please point me in the right direction.

Our TCM Tune (HUGE DIFFERENCE in daily driving/performance driving). Our CAI is in final beta testing right now (hopefully less than a month before production) and Corsa will have an exhaust marchish ;)

After we break into the E69 (Bosch ME9 family) ECM we'll begin development on a single turbo kit but thats quite a way off :)

Search is a nice feature on this forum..... Considering your the owner of the forum, you already knew that right?
Did you read my first post where I stated, "I just did a quick search and came up empty.."? ...and "If this has already been discussed, please point me in the right direction."

How was your post helpful to anybody?

Okay. What type of gains are expected from the TCM tune?

In regards to Turbo - don't single turbo systems have enough lag to make people prefer supercharging? Why not consider twin turbo? Or would that turn out to be too expensive for the intended market?

Thanks....

TCM gains are about .4 in the 1/4 just by reducing the huge lag between shifts, a properly sized single turbo will package better and still spool fast on a stock 3.6L DI.

I don't have huge lags between shifts. There must be something wrong with yours. What are your ET's before and after?

There is a ban feature too I think. :cool:

You do you just dont know what you are looking for till its gone, The car goes NEGATIVE timing on the 1-2 upshift LOL the fact it kind of lazily slides into gears is gone in my car as well they are very precise now. The lag is the ECM pulling timing (commanded by the TCM) between shifts, once thats gone gearchanges are far more precise and quicker hence the ET drop.

As far as the info goes, I try to help.. now someone find me a Nav reciever so I can dump the drive :D

GTP, I would still like to see where you are getting .4 in the 1/4 from. If it's a guess, please state that it is a guess. If the TCM is telling the ECM to pull 1-2 degrees of timing, that is more like torque management. Still, it does not account for those types of gains on any car when programmed out. .15 is more like it. If you have solid evidence, it would help a lot.

These gains are from an accelerometer that I use when I test cars for magazines, The shift times on a stock CTS are about .3-.4 seconds each total command to completion on my car they are about .2-.25 seconds and as far as 1-2 degrees being pulled i'm talking more like 25+ degrees IE it goes from full timing to -4 on the 1-2 upshift stock. Shift time is an easy way to drop some ET while keeping things reasonable as far as longevity and the fact the engine doesnt have to take forever to ramp back in 25 degrees of timing helps alot.

BTW I'm not removing 100% of the TM, thats foolish this is about a 50% drop over stock as far as the timing it pulls.

Also if the owner wishes we can set the sport mode up to actually DO something LOL Even faster shifts for track only use and the choice of two clutch control modes, the latter is VERY brutal and feels like a 4L series with a shift kit LOL

D3 has been VERY busy working on this new platform, developing a great deal of new products. We have been focusing primarily on this new platform in order to finish development prior to the CTSV's release. We will be releasing a laundry list of new components that are dealership compliant and user friendly. Some stuff has already been leaked out, but the cool stuff has not been unveiled just yet! Obviously we will have all the basic bolt ons that make great usable "safe" power, but we will also dive deep into the engine to see just what this 3.6DI motor has to offer. Look for updates for new products on our brand new website coming online shortly!

Thank you,

This makes more sense. I can tell by this post that you have more knowledge about the inner working of the sensors than is really evident from just this thread. You may have established that knowledge in prior posts, I'm not sure. Anyway, I'd be a candidate for actual track testing when you get to that point. I'm headed to Rockingham in 3-4 weeks to get some baseline times. That goes for everyone interested in seeing what their mods are capable of. I am a very, very good 1/4 racer. If you want to test some things out, let me know.

Maybe something is wrong with the search feature?

GTP has been doing an excellent job keeping us informed on all of his hard work and new ideas and products! He has been Saturating the forum with excellent information! Thank you GTP!

Not to mention my game plan thread where I have worked with most of the base modifacation companys.....
Now that you mention it, I do remember both of those threads.. I either typo'd in the search box or just wasn't comprehensive enough it.. I'll take a look at those discussions..

Thank you!

It looks like we have some interesting possibilities for the 3.6 DI CTS.. If the CTS is going to be $70k (I'm hearing all different prices), it's going to be pretty exclusive. Not only that, but 550+ horsepower may be a little more than some people really want or need. Would I want it? Sure as heck, I would. However, it'll likely be too expensive for me to buy new. So a 3.6 DI CTS with an extra 50 or 100 horsepower would likely be very, very popular... Something that can easily beat G37s, 300Cs and the like...

That is the plan! Fill in the gaps. As mentioned we are working on a program to do this. Can get into too much detail, but look for something to fill in that price & performance gap.

Thanks,

Interesting options. I would be concerned with shortening the shift time, but maybe this is just me. You have more experience. Would I like to see 50HP gain? Yes! Faster shifting? Yes!
My dream set up would be to change it only in sport mode. That way the “normal mode” would be untouched but if I wanted to really go there would be the real sports mode. Would it be possible? How much it would cost? What would be involved in this mod?

Dr D and GTP, pls post to this thread when you have a product to sell.

Thanks

We most certainly will keep everyone posted. We will have our new website up soon with all the list of modifications we will offer for the new CTS. Very exciting times!
