Yeah, that jiggity76 guy is an alright dude! That piece looks good in its new home!

Okay, further research indicates that the cluster uses a NDM457C chip (Nippon Denso) which is an EEPROM. There is a software/hardware combo, for about $80 (from China), that can program the chip "in circuit with appropriate probing of the chip. The NDM457C is exposed through the plastic case, so disassembly of the cluster isn't even required. The software allows for the clean entry of mileage, so "by hand" decoding of the EEPROM is unnecessary. Software/hardware at: http://www.microcontroller-cafe.com.ua/products/automotive/NDM457C Such system also reprograms the digital clusters in: 1) HONDA Prelude, 1994-1996 (OKI 16911G) 2) LEXUS LS, 1996-1999 (TC97101P) 3) LEXUS ES, CS, LS 1992-1995 (NDM457C) 4) GM Cutlas Suprime International, BUICK Regal 1991-1995, PONTIAK Grand AM (NDM457C) 5) GM Safari, Savana, Gxpress Astro, Caprice (Delco 51006A) 6) BUICK Reviera 1996-1999 (TC97101P) 7) SAAB 900, 1994-1996 (59C11) The problem is....its $80! Anyone else have the need to do any of this kind of work (odometer modification) on their UB3 or other NDM457C cluster?

There are two versions of the Digi-Dash, can you post a pic of the one you have? The UB3 looks like this...
