Where exactly is the MAP sensor on our engines (2.0 LSJ) ? Also what wire is the MAP lead wire? I'm trying to wire up my DevilsOwn meth injection and need to splice the progressive controller into MAP lead.... Help please

 

its a MAF!

 

The Map is located on top of the manifold to the left of the supercharger housing (near the serpentine belt)if you're looking at the front of the engine. It should have four wires to it... dark green/white, light blue, dark green, and gray. You want the gray one for a signal.

 

there ya go man.

 

thanks a ton!!!! i'll get it hooked up asap

 

No problem. That info is according to alldatapro. Im not near a car right now to verify that, but their info is correct 99% of the time.

 

He's talking about a MAP sensor, not a MAF sensor. MAF cars usually have a MAP sensor to read barometric pressure changes as well as act as a failsafe.

We actually have all 3 sensors, plus an additional MAP located before the supercharger but after the throttle plate. The car uses MAF exclusively for fueling but calculates projected models of incoming air based off the two MAPs and TPS to make sure the MAF and electronic throttle are operating correctly. When these models don't match up, thats what causes limp mode. Little FYI.

 

which should i use for the devils own controller? i located the map you spoke about and used my multimeter, both the green and the gray show slight voltage with the ignition off and about .5v when the switch is on. Im terrible with wiring

 

Ahh I see. Thanks for the FYI.

 

I'm gonna go with gray. Heres a pic of the connector with the wires labeled.

 

i'll give that one a try tomorrow and keep you updated, thanks again man, much appreciated.

 

Which wire did you end up using? I have the same kit, how does it work?

 

oops I forgot to update I used the # 4 MAP Sensor Signal as pictured in the above diagram and it works perfectly.

 

That was the grey one right? As it looks front the picture above.

Oh yeah, one more thing, where did you get at the wire to splice onto it?

Bump for more info!

 

update on thjis please? is it the gray wire? I am in the middle of the install now

 

Yes it was the gray wire, good luck man!

 

yep got it thanks guys
