GTRay - I just noticed the list of vehicles you have in your signature. I own a FD and used to own an Rx8. Is it just me or does it seem like the rotary crowd is just a little too anxious to go out a stick a fuel computer on anything with 4 wheels smile ? I'm sure it's just been engrained in our heads from owning rotaries. I've done a lot of tuning with my E6K in the past so I'm looking forward to messing around with the xterra.
