well i recently bought a digital dic from ebay, it was a dic out of a 97 gt. i am trying to swap my analog dic to digital in my 98 grand prix gt. i hooked up the dic knowing that there is an issue with the 97 dic only working with a 97 grand prix. i wanted to test it myself. everything hooked up correctly reveals that in fact this is true. the information for the mpg, oil life, miles,etc flashes 0.0 on the screen. the doors and trunk ajar indicators work though. so now i am buying another digital dic from ebay that came out of a 2000 gt. i'm hoping it will work as it should. my question is to all the other folks that attempted this swap...when you hook it up and turn the car on, will the information automatically adjust and work correctly, do you have to reset the computer on the dic somehow, any info on this would be great, please let me know. i have my car torn apart for a while waiting for my other dic to arive. i did install a cheap oil pressure guage which was interesting, anyway i have a 97 digital dic that works just fine that i dont need anymore so if anyone is interested i paid 60 bucks for it and i want to sell it for a reasonable price. let me know.
