I pulled my turbo motor and setup out of my teg (it was running just fine) and put it in my hatch. And for some reason now, when i try to run off the Motorola map sensor the car will run for about 4-5 seconds and sputter and die. But as soon as i switch it back to the OEM, its fine. Does tht mean my Motorola is bad? Has anyone ever had a problem with this map sensor? I have checked the wiring like 25 times and its right, so i know its not that. any help is greatly appreciated.

Just for the sake of whoring my new car:

 

I'v had the same problem. It turned out to be the wrong motorola 2.5 bar sensor. Theres two models, I bought a new one from xenocron and everything worked out fine.

 

Well this one has been woking flawlessly for 7+ months in my teg, so i doubt thats the case hare. thanks for the input though.

 

same ecu from the teg?

 

Yeah....everything is the same. Im wonderin if the sensor might have gotten banged up at some point. it doesnt make sense except the sensor is bad.

 

the sensor is sensitive. I received mine in the mail from xenocron and I would start the car with it and like your problem, start for about 4-5 seconds and sputter and die. when I installed mine I never cut off the OEM plug so with my 2.5 bar map plugged in I was getting no reference voltage. without the car running, you should be getting around 1.8vdc for reference voltage. I was getting like .285VDC. the sensor was obviously F**ked. I ended up having to buy another one and when I plugged it in, it worked flawlessly. check your reference voltage with just your key to on(no start). oh BTW, if you plugged this thing in backwards once, it's f**ked. and my OEM sensor worked T*T's

 

Yeah i had the plug for it backwards to begin with.

So im assuming that would have toasted it. i just ordered another one so hopefuly thats the problem.
