So with these cars sharing an engine and transmission with the corvette why cant we opt to have the dealer reprogram the ECM to Corvette specs? I feel that if I improve intake air flow the car could easily make the 430hp/424lb ft that the Vette makes. Any thoughts? If there is GM Tech on here please chime in.

On a side note, for an extra 270 dollars the Solstice GXP and its Saturn brother could be reprogrammed to bump power from 230hp to 280hp. Id pay 270 to 300 for another 15hp that keeps my warranty.

It's you exhaust system not big enough don't think the SS is 2 1/2 inches that is one item the box that both pipes feed into another and early vetts only had 2 catalytic converters we have 4.

Won't work, plus a GM dealer can't do that.

You would need to have someone tune the car specificly not just copy some other cars calibration.

The weight of the SS is far different from the Corvette so I'm sure the timing tables would be different. The Camaro SS would be a closer option I would think.

Yeah, GM Tech cant do that, their software doesn't allow them to do it. You would need HPTuners.com >> Performance At Your Fingertips to start playing around with that kind of stuff.

 

[firehawk238]

Hmmm.... All good points. I am pretty sure the exhaust is 2.5" though. Ill measure it later though.

 

[firehawk238]

Also my point was more along the lines of why doesnt GM offer a tuning upgrade that can be had with the sale of the car or even as an upgrade that is warranty friendly?

As others have said, the intake and exhaust systems are entirely different. This completely changes the characteristics of the engines performance and all of the tuning parameters from a Corvette would be off.

The difference with those cars are they came with turbochargers, adjust the boost levels some and wham big power gains. Also that upgrade from GM was actually them changing the turbo to a slightly larger unit to make more power.

A GM dealer won't do that even if our equipment was capable. When you change tables a a specific vehicle it has to be re-certified in that specification(tune). "It ain't gonna happen". The best thing to do is get a tuned ecu that has an image of the original tune(better tuners can do that) or swap it out each time you think the car may have to be scanned.

So you are telling me that for 270 dollars a chevy dealer installed a larger turbo and tuned the car on top of that?

Also I suppose my original title is a bit misleading. I am not meaning to literally dump the vette bin files into the SS ECM and call it square. I know that GM tunes their cars very conservatively so why not offer a more aggressive tune that can be had from the dealer?

The turbo upgrade was $650, they also had a GM Performance Plus tune that bumped power levels a bit - I am not sure how much that cost.

The turbo was not changed out, it used the stock turbo. What was change was the MAP sensors and software. The price was $900 when it was first released it, then went down to $600. I had it on my 07 Sky Redline ...

Also I wouldn't get to hung up on those 415 numbers. I don't think GM recertified the engine. We have seen the stock dyno numbers in the 360rwhp numbers, which is pretty big for just 415hp with a 6l80e.

 

[Boosted]

I stand corrected, I was mislead by the name of the kit being turbo upgrade kit.

 

[firehawk238]

19212670 Turbocharged engine power upgrade kit

Here it is. I was wrong on price though.

 

[firehawk238]

Anyway, just think it could be good for business to offer a more aggressive tune that didnt effect warranty. Im positive it would sell.

It's possible the tune is the same, but with different intake and exhaust there is a difference in power. Also I truly think the power is under rated at 415.

As for the LNF 2.0 they were build from the ground up for increased power. They came with forged internals, sodium filled valves and a chassis and drive train built to handle the power. GM would have to go through a ton of R&D to certify for warranty.

I'll restate this a tad:

The ONLY thing to do is get a SECOND ecu that has the tune AND swap it out EVERY time you take the car to the dealer.

... Remember if there are open TSB's, etc (which show up when the RO is created) it gets hooked up and a tuned ECU will automatically VOID THE WARRANTY! The ECU remembers that it has been reprogrammed even after you 'untune' it and this also automatically VOIDS THE WARRANTY! Ask any Camaro guy. The only way around it is to have 2.

But I don't know for sure what other parameters the ECU 'remembers' ... so it may actually be deducible by mileage, total engine hours, cycles, and/or a myriad of other things that the ECU was swapped!

Remember this is Global Architecture 2 and big brother is watching!

Using two is going to much harder than you may think. You can't just buy a new one from a dealer. GM won't let them sell one without getting the old one in return. That leaves a used one from a wrecked SS ... You may get lucky and get one imported from down under, don't know if they are any different or not. They are making it much more difficult to beat the system. LOL ...

Yup, I'm well aware and know you gotta 'find' one as well as a real good tuner who doesn't ask a lot of 'questions' !!!

When you can tune out the restrictive detuning code and open up the full mechanical prowess of the engine you tend to blow things up that can't handle it! Makes for expensive warranty claims.

You are probably more correct than me. When I had my 2007 V I had a tuned box from "Wait4me" tuning and the factory uplink did not see it, but it didn't see anything and reported it as a "Can Not Read - Try Again". Things probably have changed since then. Oh, and I did have 2 boxes anyway. He sent me a tuned box and I had the option to keep the core. I also have 2 boxes for my 2003 Silverado, one tuned and one stock for backup.
