Hi all,

I will be buying the universal stage 2 kit for my 1995 Rx7. It currently has the stock 1 bar map sensor and I was wondering which controller I need to purchase and whether the voltage controller is compatible with my setup.

thanks

Your not going to want to use that with your 1 bar, You can get a second 2 bar sensor and let the controller run it and read it or use the voltage controller on the MAF sensor.

hi dvldoc, thanks for your quick reply!

I'm a total newbie when it comes to these things so excuse my ignorance

I just spoke to my mechanic and he told me that I will not be needing more then 1 bar, due to the fact I will not be increasing boost substantially and will only be using the kit to decrease temperature and increase reliability. In the future when I upgrade things this might change.

Also my ECU is quite similar to stock (not apexi or haltech) and therefore is only compatible with my current 1 bar map sensor.

Therefore out of the 4 controllers which one do I need to get?

Thanks for your help!!

When it comes to map sensor 1bar is for reading vacuum, Because the sensor takes in account atmosphere pressure thats why it's one bar.

2 bar is for 1 to 15psi of boost, 3bar is for 1 to 30psi of boost. The Mech should have known this. 1 bar map sensors are for n/a vehicles.
