Is their a software out that I can drive to a place and have them download a tune flash on my current ecu without removing it?? Or maybe one I can buy and download from my laptop? Do additional tuning from my laptop? Sorry I am used to vw 1.8t engines and the various methods of "chiping" those cars. APR was awesome, especially with V-tune.

 

what year is your Z

 

I come from 1.8t (blown20v) also,revo big-turbo guy, and yes there are several that are similar..

UpRev Osiris - http://www.uprev.com/products/osiris_NI.html
CobbTuning - http://www.cobbtuning.com/products/?id=3686 (alot like revo)
Technosquare - http://www.technosquareinc.com/350z.htm

Im sure there are a few others but those are off the top of my head

 

Im guessing its an HR.

only option for the HR owners is Standalone which costs$$$$$
