Will be doing some tuning on buds new Z. Rather no use his ....
Betcha GM start installing some sort of tamper film on ECU/connectors?

I honestly don't believe having a separate ECU will do anything to help you keep your warranty. If your car blows up on the track or anyplace else and you put the stock one back, there is no data to contribute to the problem, so GM will void your warranty because I would imagine they are smart enough to figure this out. If I am missing something, please enlighten me, but when I considered this with my 2008 Z06 each tuner that I mentioned this to, gave very vague answers regarding this being a loophole. My sense was they know it will be easy for GM to build a case against you if you replace the ECU, have a problem and then put back the original one.

"just figure it out" not sure how that would be possible unless you were blabbing it all over the internet! LOL

Well...even an idiot can figure out that if you had a catastrophic failure on a motor, then go into the ECU to pull codes and there is NOTHING in there, that the ECU was swapped out.

Doesn't take a rocket scientist or a computer hacker to connect those dots...

NICK YOSKIN

So are you saying that if you pop a head gasket or bend a rod or etc... that there is a code for that? Do you have any tuning experience?

NICK YOSKIN

I get what your trying to say....there would be evidence of a misfire code. Just because there would be no misfire codes is not conclusive enough to say whether the ecu was swapped. Seen plenty of rods tossed threw blow and no codes were saved.

GM has already won this battle. The car has a 4G hotspot for a reason.

The ECU isn't the only place that data is stored in the car.

No...you don't get it...

There will be NO codes...NO DATA (engine temps, RPM's, throttle position, etc.), zip, nothing, NADA...when you plug that new ECU in, there is nothing stored in it.

Sure...IF the engine will run you could get something stored into the memory, but in the case of catastrophic engine failure you are screwed.

My C4 ECU stores the last 5 minutes of running...I'm sure the new ECU's store MUCH more than that.

P.S. And do you think that OnStar system is only for your emergencies? When time stamps in the codes don't match up...they start digging deeper. And they hide stuff in places ALL OVER the car...in different (unrelated) modules.

And, last but not least, what you want to do is considered FRAUD. I'm sure GM lawyers would love to get their hands on that information...

Bottom line - tamper and be prepared to fight but it's you against GM - a huge Corp. Will you win?? you'll go broke trying though

harlold

It astounds me how many will go through such steps to defraud a company. What you are proposing is illegal.

Want to tweak the ECU? Know the risks and play the game.

Want full warranty? Stock is the way to go.

So if there is a power loss to the computer, it saves the data now? I know in my c6 and every other car I own, once I pull the battery cable, everything is gone.

It would seem to me that swapping the ECM and then saying that the battery as pulled at some point because you were installing something electrical would be a completely acceptable answer.

I don't get it.....if you break your car then pay to fix it.

wtf is wrong with people today????

Nosferatu

it's people that try and defraud that screw people over that has made if difficult for those with legitimate problems.

Those with modifications that have a legitimate issue NOT RELATED to the modifications get turned away because of someone trying to get a free repair/fix.

It's unfortunate that just because a car is modified a car manufacturer will claim the modifications cause the fault (even when it obviously did not).

JoesC5

I don't think pulling a cable off the battery clears everything, no more than hitting the delete button your computer removes all traces from your hard drive, or unplugging it from the wall outlet.

ANTIVNOM

Ding. If you want to mod your car from stock, that is great. BUT ACCEPT THE CONSEQUENCES for your action as it is NOT GM's responsibility any more.

If you want to play then you should be prepared to pay

1991Z07

If you think the ECU is the ONLY place they are storing data now, you are only fooling yourself...

And if you don't think that GM have some guys on staff tasked with scouring forums JUST LIKE THIS looking for this kind of ammunition, you are crazy.

harlold

Id love to know what kind of data they are sending back with the built in cell connection.

DLC7

I don't get it.......if GM misrepresents what the car can accomplish, and requires a warranty voiding tune.....you get to pay to fix it



Wtf is wrong with people today?

DLC7

That's debateable.....for if they do have staff scouring this forum, they should step up, and answer too:

1. VERY significant orange peel paint.
2.misaligned body panels.
3. An ECU that requires a warranty voiding tune.
4. Serious questions on whether this car can be run for more than 15 min @ greater than 70 degree temps. (distinctly different than #3.)
