要記錄觀察渦輪增壓值, 除了加裝渦輪錶之外, 還可以在進氣岐管或其他有壓力源的地方安裝壓力感知器(MAP, Manifold Absolute Pressure), 並把訊號導入ECMLink V3進行Log.
有人問, 為什麼不用原廠進氣岐管上的 MDPS 的訊號呢? 因為它是沒有辦法紀錄增壓值的, 只能判別壓力的變化, 所以只好另外尋找合適的產品.
本來選定的產品是AEM MAP Sensor, RRE MAP Sensor Adapter(轉接座)也準備好了, 這時候忽然發現Omni 3 Bar MAP Sensor, 它可以直上原廠MDP Sensor的位置, 更棒的是直接對應原廠線組接頭, 不用重接線, OMNI官網 的 產品說明 如下:
Omni Power USA 3, 4 & 7 Bar MAP (Manifold Absolute Pressure) sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip. Pressure changes are calculated on a true linear 0-5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows the Omni Power USA 4 Bar MAP sensor to remain a minimum of 99% accurate from 32 degrees F to 180 degrees F through out its range of scale. With the true linear pressure vs. voltage scale there is never a need to re-tune at different altitudes as with other sensors. Competitors sensors on the market don't have true linear scaling which can cause your engine to go out of tune with elevation changes, often resulting in idle problems, poor drivability, and catastrophic engine damage. Omni Power 4 bar MAP sensors can precisely calculate boost pressure from 1-43+ psi (7 bar 1-80+ psi,) while still allowing smooth stock OEM drivability at any boost level. Conveniently packaged in an OEM dimensional housing for easy install and an OEM look.
Cases are designed to withstand in excess of 130 PSI without leaking.
-40 to 260 degrees Fahrenheit temperature operating range.
Able to respond from 10% of the pressure scale to 90% of the pressure scale in .001 seconds (the fastest response time of any MAP sensor on the market).
Automatic temperature compensation.
True linear scaling for perfect drivability at all boost and vacuum levels.
Compatible with all aftermarket engine management systems.
Minimum of 99% accurate over full scale range under all conditions including temperature, altitude, and humidity changes.
Allows smoother engine operation, higher boost levels, and better drivability than competitors turbo MAP sensors.
Direct plug and play for an easy install and an OEM look. Dimensionally identical to the stock MAP sensor.
Each sensor is hand assembled, pressure, and function checked in the USA for unparalleled quality control prior to shipping.
