OK Here is a different sort of question.. I have a 2004 350Z that I am considering passing down to my teen. It is a Roadster and I am installing a roll bar to make Mom happy. What I am concerned about is the speed. I know that the I am currently limited to 156 MPH and I want to know if it is possible to limit it to 80MPH until he learns to how to cruise at a reasonable speed.

Any Hints?::

 

UpRev tuning software will do it

 

Dad of the year....one for having faith but ensuring his/her has limits! If you don't have a local tuner with the knowledge(many might say it can't be done). Shops like Z1 or UPrev themselves can send you a map along with the cable for your tune!

 

Who sells a roll bar for the ZR that will 1) fit the the OEM fake rollbars in place, and 2) allow the top to be closed?

Also, "street" roll bars, at least all that I've seen 1) would never really support the weight of the car, and 2) are risks for head injuries because street drivers don't generally wear helmets.

 

OP that's a very smart idea and +1 what everyone else said, Uprev tuning software lets us limit the speed to whatever you want, and is easily changeable when you decide its time

 

+1^, plus you can set rpm limit also which can be good as far as someone trying to street race or hot rod around town. Nice of you to allow your son to take over your car!
