How can I run 2 computers in a 2010 camaro one stock & one with a tune ????

[2010 Bumblebee]

Hello,

I hope I chose the correct category to place my post.

Without all the technical terms and abbreviations that I don''t know, is it possible to copy a 2010 camaro L99 V8 A6 computer and run either computer at any given time.

Another words have two computers and swap them back and forth? One with the stock tune, and one with another tune, to play with, or other tweaks??

If so will the car or the computer tell on you ? Will it throw codes? Will it say hey I've gone 1000 miles since the the last time I was plugged in something must be wrong ??

Is the ECU checking in with the odometer or is the odometer on the ECU??

If possible what's the process? And how much does a new 2010 camaro computer go for right now?

What is the computer part number or spec number ? (is there more than one part to it?) E38??

What software do I need to do it ??

Any links to the parts or software??

I just want to play with stuff. My car is 100% stock. I like to tinker and learn stuff. I'd like to turn off the AFM and play with the cooling fans, shift points, tune it, ect.. But leave it stock.

The 2010 ECM is 12633238. You can find the price at pace or gmpartsdirect etc or ACDelco.

It will need to be flashed by a dealer (or Chuck at Corvettes of Westchester) so that it knows who it is and can run your car.

In the past ECM's have been swappable. GM may have added something for 2010+ that makes this harder. The VATS (security) at the very least needs to be learned on any replacement ECM. Keys are exchanged between ECM/BCM/IP/Ign key. Also the crank angle sensor error needs to be learned.

If you have EFILive you have the right tools. And maybe a good idea to get the 2010 GM service information.

You are out to dry on the TCM side, the T43 is built into the trans so swapping between 2 modules isnt going to happen. For the ECM, an E38 runs about $130+ship online, usually you can have it programmed with your VIN so all you have to do is plug it in (new ECMs learn security instantly).

If you built a wiring harness that split the ECM connectors, if you isolated them when that side was not in use it theoretically could work. Honestly its probably too much trouble, swapping ECMs takes only a minute or two after you've done it the first time.

Ok, looks like we're back, thanks guys, carry on... :cheers:

$130 for a new '10? Where?

$130 for a new '10? Where?

Check this site out:
E38 ECMs $129.99+ship (http://www.whiteautoandmedia.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=41&category_id=19&option=com_virtuemart&Itemid=54)

Drop down box allows you to select 06 thru 10 ECMs.

:) And "Availability" = "Not available". :(

This is from GMPD (I can't tell if they're available/in-stock):

12625455 Emission Control System Hardware MODULE Price:$143.49 S&H:$31.57 Total:$175.06


Is that the right part number...?

:cheers: :rockon: Yes for '09 ECM. '10 = 12633238.

You would think GM could manage to design the software so that every year didnt need to have a different part for every model year. They manage to turn the same hardware into different hardware with maybe only one bit being different. Bing.....divide by zero and disappear. :doh2:

Maybe these guys have not heard of "parts proliferation" prevention. :doh:

Bummer, didnt even pay attention to that. Almost bought my extra E67/T42 combo there, just clicked the E38 screen and checked the price.

When I put in 2010 Chevrolet Camaro, part number 12625455 came up.

When I manually enter 12633238 this is what comes up:

12633238 Emission Control System Hardware MODULE Price:$156.79 S&H:$34.49 Total:$191.28

Why is it's price different than the other...?

Not only part proliferation, but price-list/catalog proliferation... :doh2:

Yes there is probably a VIN breakpoint where they go from '09 to '10 ECM's. Holden calls this RPO "BSI". '10 Camaros may have even started with an 09 ECM (GMPX mention two different ECM versions in another thread) and then gone to 12633056/12635863 10 ECM and are now at 12637084 - also '10 ECM. And there may have also been another '09 OS.

Even GM is suffering challenges in the field with this as they upgrade to 12635863 or 12637084 and TIS lets them dump it into an '09 followed by a lot of silence. :help2:

What makes this even funnier is that now in TIS an early VIN which shipped with an '09 ECM and OS is now listed as having the latest '10 OS and the history now shows an '09 OS engine seg for example was/is part of the '10 OS. :) Which is fine if the seg layout is the same but.....given how many '09 E38's are being bricked...maybe not.

With a raw ECM at the factory no doubt GM can turn a generic E38 into any year they want (am convinced they all start out as equal pieces of hardware give or take a different component manufacturer for caps or something but may be wrong on this), but once it has been IPL'd with a certain year then thats it.

The info on the AC Delco site is more up to date than GMPD etc and has more relevant info re the PN's and what they do and dont do year by year IIRC.

I would guess the price is different due to a base cost price change. Or an accountant had a hangover or something like that :).

Have seen this with bolts for example. 1 x bolt = $19. 1 x same bolt, different color = $1.50. FIIK. You dont want to lose the expensive bolts. :)

You would think GM could manage to design the software so that every year didnt need to have a different part for every model year. They manage to turn the same hardware into different hardware with maybe only one bit being different.
The change GM made that is causing the error in my opinion was unnecessary, I suspect the changes were made without thinking about what was going to happen when 'x' went in to 'y' because everyone will check the part number!! Most of this could be solved if GM stored the service number of the ECM in the flash, but they don't so there is no way of knowing what ECM revision you are dealing with unless you check the label on the outside of the ECM.

Yo

Hi, I didn't mean wire them both in at the same time, but swap them :)

[Blacky]

If you do want to run two ECMs, that will require using two VIN licenses in your FlashScan device. That is because FlashScan licenses against individual controllers, not against the vehicle.

Ha ok, from the way your original post is worded it sounds like you wanted to be able to switch on the fly (well stop car and restart using other ECM).

I do it this way now, but my factory computers have been sitting under my rear seats untouched for close to 9mo now.

Yep, but if he's going to leave the factory ECM alone, he can pull the tune, license the spare ECM, and flash the factory tune into the spare ECM.:rockon:



This said, only swapping the ECM wont yield you the results you are looking for. Unfortunately swapping a T43 isnt easy as its inside the trans, if you're concerned about the warranty then maybe tuning isnt the right way to go for you right now. Something to think about.:help2:

Yes you can imagine pulling the ECM from a G8 or Camaro to check the hidden PN. Under the battery and requires additional work other than just unplugging and dislodging it

Is the "hardware number" or "calibration" or "OS ID" or "BCC" not actually related to the "Hardware" ? :)
