hey what do you guys think of this map sensor

http://www.thmotorsports.com/omni_po.../i-282900.aspx

Omni Power USA 2.5, 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 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.

Key Features:

* 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.


I am going single soon and well with that comes upgrading the map sensor. I was going to go the route everyone else does but then I ran into this. What you guys think?

I wonder if it has a standard GM connector so that an FD specific harness/adapter can be used.

does the standard GM sensor compensate for temp changes? I really am leaning towards this one but at the same time I am a little worried since I am pretty sure I would be the first to try it.

here is the omni power website http://omnipowerusa.com/product.asp?P_ID=158

here is a picture of the sensor.

It is hard to imagine that something as basic as a pressure sensor could cause problems (if you calibrate your ECU to work with it correctly). Fast reacting is always good, though I am not sure the stock sensor is particularly bad in that regard.

I can't use the stock sensor seeing as how I might be going over 17 psi. That's why I was going to go with gm sensor. Seeing as how this sensor seems to be a lot more advanced I kinda want to try out.

The standard GM 3-bar map sensor is pretty much proven at this point (and you can get the sensor and harness for $100 or so: http://banzai-racing.com/store/3bar_...r_adapter.html).

However, I don't want to discourage you from trying it. Options are good.
