Are the map sensors from the NA and SC 3800s the same??

 

No, they are different

 

K thanks..

 

The NA one only reads up to 1 bar of pressure, the boost ones read 2 so they know the boost the engine is pushing.

 

Ok, if needed could I put the boosted MAP into a non boosted 3800?? This is highly unlikely but just in case I have to drive the backup btch..?

 

No, they're not swappable like that. The output voltage has the same 0-5 volt range on both sensors. The 2 bar just has bigger jumps between each voltage point. So 14.7 psig will be nearly maxed at 5v on a 1 bar sensor, but a little below 2.5v on the 2 bar sensor. The pcm is tuned to know what value to expect for a given voltage, so just swapping them would probably freak out the pcm.

You could tune the NA engine to to work with the 2 bar, but it wouldn't make much sense. You can grab a used 1 bar from a junkyard for dirt cheap if you want a spare.

 

Yea, ok so the problem was I was told 60 bucks from the guy at the junkyard.. He was a new guy there..

Went to talk to the normal guy I deal with there, and got it for 5 bucks..

Good info to know tho, thanks..

 

That first guy was an idiot. Brand new retail is only like $45. The cheap aftermarket replacements go down under $20.

With all of the people that have done top swaps and such, you could probably get one for free from a local off one of the forums. I bet most get tossed in the trash as they're near valueless.
