V1 Odometer to Zero - Yay!

[Lonny]

A local guy loaned us a programmer to write to the M95080 chip located in the BCM.
My son Austin and I used it to read our chip and found the location of the odometer's memory and set it to zero.

 

[Ross]

Great find! So if you found the location, can it be set to 4000 miles, and be rewritten to the BCM?

Burninating the countryside
Burninating the peasants
Burninating all the peoples
And their thatched-roof cottages!
Thatched-roof cottages!

 

[Yustas]

Nicely done! What is the offset?

 

[Iwanttogofast]

I really like those gauge faces. Where did you get them?

Lonny, are you going to offer that as a service?

I see the device on Amazon for $100

Not sure where the jumper wire close pin item can be found?

Someone would win the internet if they put together a guide on how to do this for the layman

@Lonny did you change offset 0000 and 0010? Did you happen to note the previous mileage and buffer value before you made the change?

@Ross If I'm reading the chip specs correctly, one should be able to adjust the value to any arbitrary number with the programmer.

 

[ctuinstra]

Subscribed. This is my next upgrade. I want to put our mileage to the true mileage on the build.

Looks like the chip is similar to this.

Awesome, I would love to set my milage back to the 17xx it really has!

[jennam]

What a rabbit hole... I guess I'll see how easy this is this weekend.... I found some details on the offsets and my buddy has a programmer that supports that chip....

 

[Yustas]

Thanks for the inspiration!
Got -80K, using modded to 5v cheap programmer CH341A and some math (linear transformation)

 

[ColoradoCryptoTrader]

anyone want to do mine if I send you my BCM?? my build isnt complete yet so I would reset mine to 0.

SEND IT TO ODO-PRO $89 dollars when I did mine

 

[Ross]

Nicely done @Yustas! I was going to buy a $100 programmer, but now you have me looking into cheaper ones.
Once I succeed, I will be willing to do it for others.
The rivets need to be drilled out of the BCM to get at the motherboard. Do you just glue the plastic halves back together after you finish? Those rivets are specialty riv nuts, so I am guessing you can't buy new ones.

 

[TheNuker]

Awesome, I'd love to set mine back to real milage on the frame/engine/trans! Following this for cheaper programmers.

Nuker-

@Ross I found this video useful:

Author covers drilling and reusing of rivnuts very well. My locations are exact the same. Coefficient is not same, but close.
