Hi, hope somebody got a answer for this one. I`ve installed a supercharger on my lame V6. The only problem I have is I have no idea what the pinout is on this MAP sensor. Btw, this engine does not have a MAF sensor.

If this doesn`t work out I`l have to rip it all off and sell it





motorola sensor (spx4078a k9632)

Thanks!

what year is the audi? thats odd that the factory ecm has a built in map sensor instead of an external. if its an older model that doesnt require emissions testing then your best bet maybe to use a stand alone. a great affordable standalone ecm is the megasquirt 2 or 3. they can be bought for 300-400 assembled and you can tune it.

It`s a 97 model. I think all the 90s 100/A6 have internal MAP inside the ECU. Anyway, I might have figured out the pinout. pin 1 (with a little notch in the leg) is Vs, nr 2 is ground, nr3 is +5V. The three remaining legs is worthless :P

Thanks anyway!

im assuming your putting a 2.5bar map sensor in its place. is the stock computer tunable to read a larger map sensor? this is the biggest problem with older ecm's. even though your using a larger map sensor doesnt mean the ecm can be tuned to see it.

I was planning to hook up a Apexi SAFC2 on pin 1 on the stock MAP. But, I`ll be honest, I put it up for sale today. It was just too much hazzle getting everything to work right Besides I have an automatic tranny and it wouldn`t be too happy adding extra HP :P
