hey everyone,
i'm working on a water injection project for a turbo car, and im going to be using a MAP sensor to determine the amount of water thats needed. Im curious what MAP sensors you guys are using for your boosted cars and what is the max PSI they can register? Also, whats the cheapest place to get them...im looking for something that can register 18-20psi

 

Our PCM's dont read boost and cant recognize it b/c the maps we use are only 1-bar map sensors. You maybee better off going to an aftermarket computer like f.a.s.t. which can regester and read boost and use a two bar map.

 

you need a 3bar map off a typhoon /cyclone. you use the stock one in the stosk position for the factory pcm. then you tee off a vacumm port and plug in the 3 bar. you can also splice into the factory wires at the map for 5 volt power and ground then use the center green wire off the 3 bar for your alky turn on

the 3bar is also on the turbo trans am

the 3bar can go up to 29 psi i believe
