Newbie question here. First off there are a lot of people here who switch out their ECU's with different tunes on them. So wouldn't this affect the mileage reading or is there something else on the car that keeps track of the odometer?

 

As far as I know the PCM holds that information.

 

The BCM keeps track of mileage not the PCM. So you wont lose or be able to "reset" your mileage by swapping to a new PCM.

 

Yep. It's in the BCM. (body control module)

 

Unplug you vss (vehicle speed sensor) located on the transmission and it will stop counting.

 

Seriously?

 

Yup. You also won't have a working speedometer. Your tac will work so if you know your rpms at certain speed you'll be fine. I did it on my leased ls balt for a whole year. You also must have a standard tranny

 

Damn that's pretty neat. Kinda makes me worry tho about ppl knowing this type of stuff

 

Lol. I feel bad for who ever got my last balt. Its got like 15k more miles than they think

 

Haha that's why I'm worried. My 05 Balt has just over 45k miles on it and was owned by a sleezy idiot down the street from me

 

That's sooo mean but funny as hell

 

Agreed^^

 

why you just use a GPS it will give you mph.....not that I would ever do anything like this but it would make it work.

 

ahh ha that could work too.

 

if that sensor is unplugged the cruise control shouldn't work either though

 

Who uses cruise control lol

 

Lol I didn't have cruz on my base coupe

 

probly highly illegal too. its the same as odometer tampering.

 

Yes it is.

 

Posting about it on the internet probably isn't smart..... Then again neither is talking about street racing......Nevermind, haha

 

the car also tracks hours that the engine has been running. so hopefuly unplugging the speed sensor disables that also. someone i know rolls the miles and hours on their lease all the time b4 they turn it in.

 

Wouldnt that give you a MIL thought?

 

Yes. U do have a mil light when you do this. And they didn't record the hours on my lease 3 years ago. I'm not advising anyone to do this, I'm merely saying its possible

 

pardon my ignorance. What is a MIL light?

never mind. google.com is my friend. aka: CEL light
