Sensor Locations

[Learjetter]

On my air-breathing G model, I used the MP port on the forward induction plenum (the Y after the air filter) when I put in my GI275 EIS. See pic, blue arrow points to port location. You may also need to check MP plumbing where it passes thru engine baffle at right rear behind cyl #1.

Thanks for the answer, I will go take a closer look.

Hey LearJet,
I am looking into getting a pair of GI275 EIS's... quick question about the MP sensors... Yours were ok out of the box since your plane is NA? I have turbos on mine and my MP gauge redlines at 37in with a top of 40"... garmin only has a 30" sensor....I cant find one to go as high as 40"....I know I will never see that but I do redline on TO.

Just curious
My shop opines that JPI has the less problematic sensors and systems vs EI and others by their experience on multiple makes and models….

There are multiple sensors listed in the EIS install manual, see attached pages. I used a variety of sensors, some from a 6cyl g3x sensor kit and some from third party sellers. If the sensor is on these pages, it’ll work with gi-275 EIS.

I love mine! Good luck! Let us know how it goes.

I think that "Garmin 30" manifold pressure sensor is actually 30 PSIA rather than inches of mercury. If so, that would be approximately 61 inches of mercury and it should be sufficient for our turbos.
