Possible to reprogram odometer 92-97?
I'm looking at buying a cluster on the cheap from somebody and want to know if I am able to reprogram the mileage.
The new cluster is way under what my current mileage is in my truck and I want the odomoeter to be accurate.
Is this something I have to send in to a specialist to have done or am I able to do it myself with the right tools?

You can reprogram the Odo, by copying the EEPROM from the old one and writing it to the other PSOM's EEPROM.
If your mileage is more than the "new" PSOM mileage, some one on FTE used a sound card audio generator on their computer and sent the tone to the PSOM to rack up the miles to match his original mileage. A 1Khz sine wave will work.

I figured out how to get 0 miles programmed, lock out count reset(back to 6) and pinion factors.. but still have not figured out the parity check encoding of the data.......
By the way, the PSOM does read down to the .00 miles but only shows the .0 in the display.

I would like to know more about resetting the PSOM. How does the programmer hook up to the PSOM? Does the chip have to be removed from the board? Is there anything specific to watch out for when purchasing a programmer, number of bits or speed for example. Can a backup be made of the "old" program?
Thanks, this opens up an interesting area for me.

caution.
THE
FEDERAL ODOMETER TAMPERING STATUTES
Altering the mileage reading on a motor vehicle is a felony. Effective
July 5, 1994, the odometer tampering statutes were recodified from Title
15, U.S.C., to Title 49. The change was not substantive, though the statutes
were reworded. Some of the old and new statutes are:
Tampering prohibition: moved from 15 U.S.C. § 1984 to 49 U.S.C. § 32703(2).
False odometer statement prohibition: moved from 15 U.S.C. § 1988 to
49 U.S.C. § 32705(a)(2).
Odometer fraud conspiracy prohibition: moved from 15 U.S.C. § 1986 to
49 U.S.C. § 32703(4).
Criminal penalty provision: moved from 15 U.S.C. § 1990c to 49 U.S.C.
§ 32709(b).

I am not interested in changing the odometer. It's that "6 change only before lockout" on the speedometer calculation that I'm interested in. My speedometer is close but I stopped adjusting it after I used 3 of the 6 times.
Thanks Subford
