I went to go tune my turbo charged civic si today, and supposedly my 3 bar map sensor is not reading boost. It's still seeing vacumm when boosting so we're going to see what happens when I put the stock map sensor back on tomorrow. We did a few base line runs. I believe the numbers were 196 whp at 8 psi, but we didn't go any further after the map sensor issue...

Anybody know what could be going on???

 

You dont have a checkvalve in there right?

No check valves...

 

Sounds like a broken sensor or it uses a different voltage range than required.

We checked the voltage and it was reading fine... Plus if it was a faulty map sensor it should through a check engine light, but it's not throwing any trouble codes.

 

anybody else have any suggestions?
