Dealership scheduled warranty maintenance soon..

[oBradyG]

Should i flash back to the stock tune for a scheduled warranty maintenance oil change and an alignment? ive seen people say when u take it to a dealership for anything u should flash back to stock? its a new car btw with only 13000 miles on it

I didn’t. I’ve got a 2019.

No, Scheduled maintenance is still covered. By tuning you just do not have an warranty on your drivetrain anymore.

Actually it does nothing to your warranty. Thanks to Magnuson-Moss they have to prove that the modification/tune was the cause of the damage.

In my case, being at over 5000 feet above sea level, my car with a header and tune still has less horsepower than what the car has at sea level. So if I ever do have a problem I'd love to see them try and prove that my header/tune was the root cause

your technically right. but there's been plenty of cases where the only way to get to that technicality is with a jury...

A bad tune even with less HP will blow an engine. If you blow your engine and they know you have tuned the ECU they will deny the warranty. Have fun in court!

The concern is that if they flashed the ecu for some reason it will screw you up. So two ways to protect yourself.

1. Flash back to stock
2. Tell them not to touch the ecu other than a reset. This is basically telling them you tuned it. For my cars I am out of warranty, so it does not matter.

Less power due to altitude, not because of the tune silly. Meanwhile starting this Oregonian sweat a bit with Gavin, Kate and Jay being so close and all in their implementation of Gavin's bullshit.

dealers can only upgrade available newer rom
99.9% your car doean t have an available upgrade so they won t flash anything
they can t even reflash the same tune and that s why they just swap ditectly with a new expensive ecu if they think the problem is in the ecu
in the case there is a newer rom for your car and they flash it with techstream/SMIII, if OFT then it will override your tune and brick your OFT, if Ecutek they won t be able to flash due to ecu lock

Correct ecutek or brzedit tuned cars dealer canooth flash they would jist swap ECU


OFT or tactrix they can flash neither system will care. OFT only checks calid of tuned loaded to oft via openflash manager. Then it check vin of car, it doesnt actually check calid of tune in car , so it wont effect oft if dealer flashes new calid, but oft will jist overwrite with old calid next time you flash with oft

[callisto]

When dealers upgrade to a newer ROM, do they go a full letter up from e.g. S10C to V00C, or can they only go from S10C to S11C?

It would be very easy for them to.

You took the car out of its intended parameters of operation. A non-factory tune is a 100% guarantee that they can deny warranty coverage.

Only if they can directly connect it as a root cause of the issue.
