Dirty Rockstar Posted August 25, 2004 Report Share Posted August 25, 2004 How is the mileaqge remembered on this thing? And more importantly, can I modify what it has to say? Or do I need to go to GM and have them alter it? Just wondering, because it wouldbug the piss out of me knowing the mileage is off.. Thanks guys!

Psych0matt Posted August 25, 2004 Report Share Posted August 25, 2004 Good question. Id like to figure that out too for when I put mine in Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 26, 2004 Report Share Posted August 26, 2004 It's stored in non-volatile memory (NVM). I've seen programmers for about $3000 on Ebay. Quote Link to comment Share on other sites More sharing options...
Dirty Rockstar Posted August 26, 2004 Author Report Share Posted August 26, 2004 Okay, any other alternatives that don't cast 3000? lmao Quote Link to comment Share on other sites More sharing options...

Dirty Rockstar Posted August 27, 2004 Author Report Share Posted August 27, 2004 But where theres a cheapskate, theres a cheaper alternative.. Ill have my dad check w/ GM Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted August 27, 2004 Report Share Posted August 27, 2004 Or you could always try to locate a cluster that has similar mileage to your car ... Quote Link to comment Share on other sites More sharing options...
Dirty Rockstar Posted August 27, 2004 Author Report Share Posted August 27, 2004 I could, But also, consider the pricing here.. I paid NOTHINHG for my cluster.. Muahahahaha.... lol.. I dont want to pay.. lol Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted August 27, 2004 Report Share Posted August 27, 2004 Or you could always try to locate a cluster that has similar mileage to your car ... Â i'm thinking that's probably going to be your only alternative. i remember Shawn mentioned something about how he tried to change the odometer value, and it re-set itself back to where it was or something. my UB3 cluster came from a car that had almost exactly 20,000 more miles on it than my car has which kinda sucks.

Dirty Rockstar Posted August 27, 2004 Author Report Share Posted August 27, 2004 Like I said, Ill try GM.. I mean, if i can't change it, no biggie.. It would just bug me is all.. lol.. Oh well.. If GM cant do it, and I can;t find someone who can, Ill just chalk it up as m car found "The fountain of youth" because the car I got this out of, there isnt a straight man's chance in San Francisco that this Cutlass had 181,xxx miles..

Â Actually, it was my Chevy Silverado cluster I tried this on. I tried advancing my new cluster to match the original one. I tried 2000mph and that was too fast. The digital odometer actually showed it was advancing, but reset back to original mileage when I removed power. At just under 1000mph, that was slow enough for the EEPROM to save the new mileage. On my old cluster, I tried to see if it would rollover... if it would, I was going to try that with my Cutlass cluster. Unfortunately, I found out it stopped at 999,999 miles and wouldn't roll over. I'm not positive the Cutlass cluster would do that, but I don't really want to find out. Quote Link to comment Share on other sites More sharing options...
Dirty Rockstar Posted August 29, 2004 Author Report Share Posted August 29, 2004 Shawn, HOW did you do this? Please, I must know! lol.. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 29, 2004 Report Share Posted August 29, 2004 Quite simple, actually! I downloaded a program called "555 Designer" (or something like that). It cranks out a schematic based on your specs. I plugged in that I wanted around 1000Hz (900-something mph) at 50% duty cycle and it came up with a schematic. I rigged up a 555 timer chip (available at Radio Shack) with the right capacitors and resistors which I already have plenty of in my electronics junk bins. I then connected the output to the VSS wire on the cluster. Â I actually used variable resistors so I could fine tune the frequency, and I had the output connected to my multimeter which has a frequency reading so I could get a visual on the exact frequency injected into the VSS wire.

GutlessSupreme Posted August 29, 2004 Report Share Posted August 29, 2004 I don't know how it works, but what if you tried -mph? (if needed) Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 29, 2004 Report Share Posted August 29, 2004 No such thing as -mph. Quote Link to comment Share on other sites More sharing options...
