If this is true then does that mean if a piggyback ecu is made for the corvette that the 2.4 ss can use it as well for tuning?

 

whered u hear that?

 

Not a chance, sorry man LOL

 

LMAO who told you that?!?!?!?! Not a chance in hell they'd be swappable.

 

Yeah, They're Swappable.... BAHAHAHHAHAHAHAHAHAHHAHHAHHAhAHHAHHAHAHAHHA...paus es for breath, Then continues laughing....AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!! !!!....Nate Died

 

Think about it man: Corvette - V8, Cobalt - L4.

There is no way they could have the same ECU.

 

Just curious: Where did you hear this rumor from??

 

im not sure i read it on the threads here somewhere that the 2.4 had the saem type of ecu my bad guys

 

No prob man. Well, whoever read it here MUST've been Joking. But still no prob.

 

Don't worry about it, just remember with every cylinder the ecu will need to manage it.

 

all laughter aside I think they have the same software with different variables (obviously) so once one is broken the other will be as well .. WopOnTour was saying something about it iirc and he is a very reliable source.

 

Hope this clears it up for the people still giggling

yeah thats what i saw that made me think this, again sorry about the confusion im still new to ecu tuning since ive never actually done it yet on my cars and im learning still.

 

Well I don't think its far fetched..could use the same generation of coding and/or hex (beta). Don't know much about the inner workings but they are probably reasonably similar.

 

Lets put it this way, not even close

 

Ah ok, I see. Same computer, Just different programming. I can see where you'd get confused.

 

Ok again, NOT THE SAME COMPUTER AND NOT THE SAME PROGRAMMING

 

Well for whatever the question was worth I think that (GTPprix) solved the issue.

 

I do not believe that the Vette and Cobalt are using the same engine controller. HOWEVER - those of you that called the guy stupid for even suggesting it are pretty wrong. GM's new family of engine controllers is very flexible and can be used for many things. The same controller is being used out there already for 4cyls, V6s and V8s. Same hardware, different programming obviously. Obviously you couldn't just take a Vette controller and plug it right into a Cobalt and go, but if you could change the software, the hardware would be quite compatible (which was his question, I believe).

 

Actually YES
The 2.4 Cobalt and the LS7 Vette both use E67 boxes SO THE HARDWARE ITSELF IS IDENTICAL (the SS/SC uses a P12 PCMs shared with the Colorado and Canyon trucks)

In fact if you look and compare their wiring schmatics they have a LOT in common...
However as Dan mentions the flexiblity of the latest 32-bit control units means they can be setup to function differently in different platforms and powertrains

Uhmmm NO the LS7 uses an E38, and the other new LSX series use an E40/E38.. The Cobalt uses an E67 WHICH IS NOT COMPATIBLE WITH THE OTHER CONTROLLERS! How on earth are you getting they are the same ECM?!!? Hell anyone off the street could see the E38 for the LS7 has TWO connectors and the E67 for the 2.4L (and others) has THREE LOL

 

I thought the Vette was an E38 as well, but ah well. Point is most of these things are at least somewhat cross-compatible, so it's not far-fetched at all.

 

Yes and no really.. The OS's are completely different, calibration segments of course and the outputs are of course different. I'll have to pop open one of the E38's I have here but I'm 99% sure from what I remember that the Microcontroller isnt even the same although they both have 2MB of flash now..

 

i really dont think so ....

 

Agreed, I meant more from the perspective of the original poster's comment. Ie if the Vette and Cobalt both used an E38, could you take tuning kits/hardware/piggybacks/practices/whatever that worked on the Corvette and apply them (at least in principle) to the Cobalt. I think the answer to that is probably yes, with some caveats of course.
