Question about flashing ECU
first of my car is 2003 g35 sedan A/T
I been reading and searching this site and google but can't find one solid answer that i want to hear or see before i buy the product
i was looking for the cobb accessport but then it stated it will not work with 2003 g35 sedan
Will the Utec Turbo XS work for 2003 g35 sedan??? anybody can confirm this or even have it on their car without turbo or supercharge just maybe combination of intake, plenum, header, cat-back exhaust and also will this help at all to gain a little more power???
thanks in advance

Your best bet is the Technosquare flash. Take a day and drive out to Torrance and have them do it for you.

Depends on what your build date is. Is your 2003 a "doggy door" ?
You might be able to use Osiris if you aren't the early 2003 - early models had a different ECU, same as the Maxima for 2002-2003.

How can you tell if the car have doggy door or not??

That's a doggy door. If you have it, it means you have an early 03. Talk to Jeff92se or search his posts, he probably has done the most research into tuning early 03's.

you should be able to use Osiris... contact UpRev to discuss you options:

Osiris is going to be your best option and should work for you. The Cobb Tuner will not work for your model.
Technosquare reflash is a good option but is a 1 time adjustment, not very economical and cost effective if you change anything in the future, plus you have to drive your car there or send in the ECU.
Wiring up a piggyback is a good option for the ability to change and adjust your tune whenever you want. UMS tuning did my tuning after I wired up my piggyback. There is a wiring harness available that will work for you to prevent cutting of the original ECU wiring harness as well. A guy on my350Z is selling one for $120 buck vs the $290 new.
The UTEC is a good option for controlling lots of things and if you can get one at a good price has a wiring harness so you don't need the autosport harness. UMS can tune this up real nice for you, NA or FI if you go that route in the future.
Your Osiris tuning option over in chandler/tempe area isn't nearly as good as UMS in my opinion.
