EJeff8

Don't run me up a wall on this, but I like the look of digital clusters. I found an HT thread in the CRX's and if he can get a 2004+ digital working in a completely analog CRX, I don't see it being much trouble in an EJ8, I just don't know what stuff I dismiss to just a CRX and what I need to add personally. Also, could a dyno shop rework the RPMs and Mileage to my EJ8? Some dude in the UK says he can, but thats impractical for me. Thoughts?
