I am going to be using a LS3 intake manifold and I was going to get a new screw in style LS3 map sensor from the dealership, but is it compatible with a LS1 wire harness?
Help is greatly appreciated.

 

No its not and even with the conversion harness It did not read the right readings. I used a ls1 map sensor plugged that front hole and used vacuum line off the back. No problems since. I speak from experience of chasing that problem down from people telling me it would work.

 

That's just what I'll do...Thank you very much!

EDIT: What did you use to plug the map sensor hole?

 

Will the LS3 MAP work with the LQ4 6.0L setup with L92 heads and LS3 intake?

Thanks in advance.

 

Jditlfm By anychance do you have some pics?

 

I do not have any pics of this i did it with the intake all ready on the car. I just made a T with the hvac vacuum line so i could have both off the back of the intake.

 

I glued my Ls1 sensor in the back and pluged off the front hole, quick and easy fix.

 

Plugged it off with what?

 

I used a bolt and put sealer on it. You cant even see it with the throttle bracket and linkage on.
