I am a new member live in Australia and am in the process of upgrading my 08 Track spec 350z work so far is Cusco front and rear sway bars, Tein Flex coilovers and edfc controller as well as new wheels Buddy Club Racing and Bridgestone Semi Slicks 245/19 front 275/19s rear and K&N filters. Now its time to start on the engine/exhaust ect. Not being mechanically gifted (at all) but wanting to do tarmac rallies I am tossing up FI or NA but regardless of either my mechanic is telling me that to get any decent power upgrade I need a new ECU but nobody makes one for the twin throttle body Z. Is this true? How much power can I get without this eg full exhaust system, does the stock ecu adjust sufficently to get good gains? Help please.

 

G'day!

Do Motec or haltech not work? or reflash the unit using Uprev.

You will need a reflash to get any decent gains. See here for a review of a stock car and the power made using uprev http://forums.nissansportz.com//inde...howtopic=23872

 

There is a whole forum for the 07-08 350Z with the HR engine.

Regarding the Haltech and Motec apparently do not work on twin electronic throttle bodies properly. Uprev reflash not an option in Australia mechanic says he is currently working on solution with Haltech tech so heres hoping.

Thanks for the link to HR forum guys

 

actually if you are staying NA you can order a cipher and the software needed for the osiris and they can do an email tune for you.
