Yes. The 06/07s are controlled with a temperature sensore in an inline CNC fitting spliced into the lower radiator hose. The 08 & up can be controlled by the PCM with that patch.

 

With the Superchips programer I improved 3 mgs. 2.96 actually. I'm now going to have the wife drive it and see if it was just me favoring it little more or if it's true. She doesn't know about it so I know she'll drive it like always. So far though I'm impressed.

 

Hello,

has anyone used the unichip power programmer on a H3 I5? I am looking to get this one and headers but want to know if there has been any good reviews of it?

Thanks,
John

 

I'm getting ready to pick up my new to me 09 tomorrow. Going to trade in my 06 with 93k miles on it. Loved it but wanting something with less miles on it. My question is, I want to do the PCM for less tune after my Air Docs, Magnaflow and bigger tires.. and I need to know if this will totally void the 25k worth of warranty still left on the 09? Anybody have any experience with that?

 

It is possible that this would void your warranty. I would recommend contacting your local dealer for more specific information. They should be able to give you a more definite answer. Thank you.

Peggy stopped by for an injection of incorrect information.

1) your "local dealer" is not employed by GM, and only GM itself can void a warranty;
2) a GM employee (like a regional service representative or district service manager) may refuse to honor some or all of your warranty ONLY if they can prove that whatever aftermarket part they are complaining about ACTUALLY caused the specific failure. Example: you install a tuned PCM for increased performance and the radiator begins to leak. We all know GM has had multiple complaints of defective H3 radiators and a PCMtune has nothing to do with it.

Magnuson-Moss Warranty Act
The relevant legislation here, the Magnuson-Moss Warranty - Federal Trade Commission Improvement Act of 1975, protects consumers from being wrongfully denied warranty coverage by new car dealers.

The Magnuson-Moss Warranty Act states, in part, in Title 15, United States Code, Section 2302, subdivision (c):
No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade, or corporate name; except that the prohibition of this subsection may be waived by the [Federal Trade] Commission if —

(1) the warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and

(2) the Commission finds that such a waiver is in the public interest. The Commission shall identify in the Federal Register, and permit public comment on, all applications for waiver of the prohibition of this subsection, and shall publish in the Federal Register its disposition of any such application, including the reasons therefore.

Under this federal statute, a manufacturer who issues a warranty on your motor vehicle is prohibited from requiring you to use a service or maintenance item, unless such item is provided, free of charge, under your warranty or unless the Federal Trade Commission (FTC) waives this prohibition against the manufacturer.

Further, under the act, aftermarket equipment that improves performance does not automatically void a vehicle manufacturer's original warranty, unless the warranty clearly states the addition of aftermarket equipment automatically voids your vehicle's warranty, or if it can be proven that the aftermarket device is the direct cause of the failure.

Specifically, the rules and regulations adopted by the FTC to govern the interpretation and enforcement of the Magnuson-Moss Warranty Act are set forth in the Code of Federal Regulations, Title 16 - Commercial Practices, Chapter I - Federal Trade Commission, Subchapter G - Rules, Regulations, Statements and Interpretations under the Magnuson-Moss Warranty Act, Part 700 - Interpretations under the Magnuson-Moss Warranty Act. Contained within these rules and regulations is Section 700.10, which states:
No warrantor may condition the continued validity of a warranty on the use of only authorized repair service and/or authorized replacement parts for non-warranty service and maintenance. For example, provisions such as, "This warranty is void if service is performed by anyone other than an authorized 'ABC' dealer and all replacement parts must be genuine 'ABC' parts," and the like, are prohibited where the service or parts are not covered by the warranty. These provisions violate the Act in two ways. First, they violate the section 102(c) ban against tying arrangements. Second, such provisions are deceptive under section 110 of the Act, because a warrantor cannot, as a matter of law, avoid liability under a written warranty where a defect is unrelated to the use by a consumer of "unauthorized" articles or service. This does not preclude a warrantor from expressly excluding liability for defects or damage caused by such "unauthorized" articles or service; nor does it preclude the warrantor from denying liability where the warrantor can demonstrate that the defect or damage was so caused.

Under the Magnuson-Moss Act, a dealer must prove, not just vocalize, that aftermarket equipment caused the need for repairs before it can deny warranty coverage. If the dealer cannot prove such a claim — or it proffers a questionable explanation — it is your legal right to demand compliance with the warranty. The Federal Trade Commission administers the Magnuson-Moss Act and monitors compliance with warranty law.

The 100% failsafe work around.
(Buy a tuned PCM and)... If you have any issues involving powertrain, put the stock part(s) back on before you go to the dealer for service.

 

100% to what Doc wrote!!!

Best bet is to have a PCM4less tune done on another PCM/TCM and save your OEM(stock) PCM/TCM in a box for future warranty work.

 

That is what I did. I got my 2010 w/5,000 miles on it so it was basically new so I didn't want to risk any chance of problems w/the dealer. If I have to bring it in for any warranty work I'm going to pop in the old PCM and TCM. I don't get regular service done at the dealer so I'm not sure if you would need to swap it out if you are planning to do that.
