same different question
what's the scalar mbar/volt ? number for the map sensor and the offset mbar number ? if i read right the offset is 2 is that correct ?
My 'Hondata 4 BAR' MAP sensor reads a bit low in the Boost range..
The stock sensor would read exactly with my boost gauge.. So I knew that my boost gauge had to be accurate.. But Now that I installed my New Hondata MAP sensor.. I had to Re-tune in boost.. which doesn't make any sense at all.. The Omnipower 4 Bar MAP sensor that I had before (Which stopped working), Worked Flawlessly, and read properly.. But now the new one doesn't...
Why would it act up only in boost, and not in vacuum?

So.. It's a wiring issue, when the stock one reads fine... And the 4BAR also reads low in a friends car...Spunkster wrote:Based on the fact you have had problems with 2 sensors, it sounds more like a wiring issue in the car.
post a datalog and calibration
What I'm saying is:
The 4Bar's read PERFECT in Vacuum,.. But they read Low in boost levels.
I didn't get the chance to check the other MAP sensor in Boost, because it Failed.

On the dyno right now and are seeing the same issue, s300 is saying 9ish pounds and my dyno says 20, car just made 553 with a 35r so I know it's making more than 9 psi. And like above it reads within 1psi in the vacum columns
datalog and dyno screen shot attached
Lucky for this engine I was on q16 and not pump gas, but it still didn't like the the timing for 9psi @ 20
