Just wanted to know if there's any way that buying a difference ecu and putting a tune on it would be detected if i switch back to the original ecu, for any warranty purpose.is there any data store on acd ecu or tranny ecu.

 

 

thinking about switching back to the stock oem intake. but haven't found one yet.should of keep the oem intake.

 

That's a legit reason to deny fixing a MAF sensor.

Your better off getting a switchable map (AP or Tactrix) than pulling the ECU. If I remember correctly some ECUs have markings to detect if they have been physically tampered with.


BTW: the Edit button works on these forums, not sure if your used to forums where it doesn't work.

 

i knew they wouldn't cover the maf sensor.but with some begging they did.but as far as the ecu, i was thinking on just laying it on top of the stock ecu.i do have a tactrix cable but can they find out that it's been tune if i switch back to stock map.

 

They are going to find the 2 ECUs before they find a different map.

 

I Agree with DaJackson... your way better off getting a tactrix cable to flash back to stock when you need too.

A second ecu is not practical as I'm fairly sure it has to be coded by the dealer to work in a particular vehicle... we don't have immobilizer code in the ecu rom any longer but I have to imagine that there is some anti theft mechanism that requires the ecu to be coded to the rest of the control modules in the car.

 

can the dealer tell if there a map switch before i take it in.i read that there's some 50 cycle memory of some sort, but don't know if that true.
