my poor jap import is limited to 120 mph due to jap laws will this stop it?

It could de-limit your Rx-7 . Or you could get a Power FC . that would also help you take away the limiter plus give you more control on whats going on with your 7, if you planning on up grading your 7.

other than the PFC , you can get other items like



ps; you do know that the link shows a de-limiter for a FC not a FD , right...

or you could get a apexi V-AFC ...

https://www.nopistons.com/forums/pub...#>/biggrin.png the fuel cut in japanese cars has nothing to do with boost the are rpm governed to 180 kph you need to have a remaped ecu put in that will have that function removed. Or remove it and use an apex power fc

the unit that you have on your link is for a 2nd generation rx7,



i think the only way to go around your speed problems is by using a different computer..... either a remapped ecu or a stand alone (power fc, haltech, etc.)
