I think my map sensor is bad, I got no CEL but the reading is too low. If I use the option of oem map sensor test , can I detect if my map is good or bad???

Per shop manual yes. what does it read mbar/volt and key on engine of?

Koeo, your map and baro sensor should read the same mbar.

The problem is that the map reads just 9psi, but the boost gauge is about 18 psi. I turn down the boost at 15 psi on my boost gauge, and the map reads 9psi.

almost the same. that is the quick way to check your map sensor

the oem map is a 1.75 bar map and lots of times theyre inacurate for on the boost side of things. If you run 18 psi and the map sees 9 psi . both fuel and timing are WAY OFF! you need a 3 bar.

You are rigth, I turn down the boost till 11 psi, but stil reading 9 psi on the map sensor. I´ll copy the values that I have on the last boost coulmn (11.3 psi) to theprevious coulmn (9 psi) just to be safe, but I´ll put a 3 bar map sensor for sure

you will blow the engine this way

Ok, I turn down the boost till 8 psi, I´ll put a 3 bar map sensor tomorrow and then retune and turn up the boost. Thanks guys

sounds good
