Chip Programming Trail On 2008s

sledneck_03 · June 22, 2008

I want to get a superchips cortexs? i beleive thats the spelling...anyway, i was wondering if they leave a trail or any chip leaves a trail for that matter on the new trucks. The cortex comes with a 2 year warrenty on motor and trans, but i would still like to know if theres a trail, so i can just go threw my dealer with no hassle

I know DiabloSport doesn't when you return it to the stock tune.

2005 and on GM vehicles keep record of how many times the PCM gets flashed. it is not something i would worry about. a handheld tuner will not cause a problem, and if you have to go in for warranty and they blame it on the programmer it can be fought quite easily

Not sure where this info comes from, but it is incorrect.

Currently the only model that actually 'counts' flashes is the new LMM Duramaxs.

Thanks

I can't tell you how valid this is, but there was a topic on another forum that said GM could tell if, and how many times a vehicle has been tuned. Not saying you are incorrect, but I am saying that I know I read this somewhere, and my source may be wrong.

the following is the p.i for calibration confirmation from GM

--------------------------------------------------------------------------------

#PIP4386: Identifying Aftermarket Engine Calibrations - 2.0 2.2 2.4 2.8 2.9 3.0 3.1 3.2 3.4 3.5 3.6 3.8 3.9 4.2 4.3 4.4 4.6 4.8 5.0 5.3 5.7 6.0 6.2 7.0 7.4 8.1 - (Apr 8, 2008)

Subject: Identifying Aftermarket Engine Calibrations

Models: 2005-2009 GM Passenger Cars and Light Duty Trucks

except Pontiac Vibe, Chevy Aveo, and All Saab Models

--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

A dealer may have the need to verify engine calibrations. If a dealer feels an aftermarket power-up calibration has induced engine and/or drive train damage, there is now a way to verify what calibration is currently in the vehicle.

If a suspicious hard part failure is observed in the engine, transmission, transfer case, or driveline, perform the calibration verification described to determine if a non GM issued engine calibration is installed. Non GM issued engine calibrations subject driveline components to stresses different than those that these components were validated to. Repairs to transmission, transfer case and / or other driveline components where a non GM engine calibration has been verified, are not covered under the terms of the New Vehicle Warranty.

Recommendation/Instructions:

Instructions for confirming Calibration Verification Number (CVN)

• Go to TIS2WEB

• Select Calibration Information (SPS Info)

• Enter VIN

• Select "Get Cal ID"

• Select ECM Engine Control Module

• Hit "next"

• Select "Complete History"

• Print

Take Printout to Vehicle along with Tech II

• Plug in Tech II

• Go to diagnostics and build the vehicle

• Select Powertrain

• Select the engine

• Select F0 - Engine Control Module

• Select F4/F5 - I/M information System / Module ID information*

• Select F1

• Compare the calibration ID and Calibration Verification Numbers (CVN) to the Calibration Verification Numbers (CVN) on the printout.

* This step may vary by controller; use the Module ID Information in the Engine Controls.

Although the part numbers will be the same for each, it's the CVN that will determine if the calibration is GM issued.

If ALL of the CVN's are EXACTLY the same, the calibration is GM issued.

If the part numbers match and ANY calibration verification numbers (CVN's) do not match the printout, it is likely that a non GM certified calibration has been installed.

In order to document the case - a CLEAR digital picture should be taken of the TECH 2 screen showing the VIN and the CVN's that do not match the TIS2WEB printout. The picture and a PDF copy of the TIS2WEB printout should be forwarded to [email protected] for verification along with the VIN and the reason the vehicle is currently in for service. Please copy your GM Area Service Manager (DVM/DSM) on the e-mail. GM will verify if the CVN's are not GM issued and respond via e-mail within 48 hours.

If both the Part numbers and the CVN are different, photograph the part numbers and CVN's on the tech 2 screen as described above, assuring the VIN shows clearly in the photograph of the TECH2 screen, and check to see if the vehicle has the latest released calibration. If the latest released calibration is not installed in the vehicle, the part numbers will not match , and the CVN's won't either. E- mail the original Part Numbers and CVN's found in the vehicle on the TECH 2 to: [email protected] to check if the calibration and CVN matches a previous release. Recalibrate with the latest released cal and re-check against the part numbers and CVN's that are released.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

its possible i am wrong, kinda hope i am. however, it would not be hard to implement this counter in the software

nbscanuck · June 25, 2008

This is if you have left your tune in the vehicle. Of course they can see that. But if you restore the factory tune, they'll never know. At least that's how Diablo works.

So they say....

but they have been able to do that for a lot longer than 05. we had an issue with our 01 tahoe that they could see the program on. our local stearlership blamed the typical piston slap of the 01 LS motors on the tune. the only thing that could have changed is that they can count the upload numbers. the diablo uses the same software as all the other ones. if one can be seen, they all can be seen.

Not necessarily. Yes, if you return it to stock, they will not be able to see your tune, only the stock tune. But on the newer vehicles, they can now see the Cal ID's for the previous 10 calibrations downloaded. if the Cal ID does not match a GM OEM Cal, they will know the truck had been tuned. This is why it's a good idea to remove your stock modules and keep them "virgins" and tune a spare set. This way Cal ID record stays OEM.

Theres no way they saw anything in a 01 truck, they were blowing smoke.

Even with the tune installed, they cant see anything in the tech2 on any 01 PCM with one of our tunes installed, they'd have to read out the PCM and compare it to a stock file in HEX to see any changes...they certainly did not count the number of flashes in this truck.
