I was just wondering if anyone had experience with the efisource's ls1 style 3 bar map sensor, and if it's better than Dsteck's 2.5 bar map sensor?

Do you remember the offset and linear values they provide?

I bought one haven't used it yet tho. It didn't come with any papers just a sensor with no writing on it in a box.

I plan on emailing them to see how low the sensor can read.

this is a direct plug in, no pigtail splicing one you used?

Let us know on the numbers. I sent a friend the link and he wants one. The numbers are important.

Denmah must know

in demah's build pics, i usually see the "GM 3 bar" with the 3 tube style pigtail that needs to be spliced in. I wonder if that's what he's referring to. this one I'm inquiring about, is a direct plug and play, ls1 style.

yes this plugs in, directly into the stock harness
it has the stock plug

it looks like an ls1 sensor with the hooks on one side

it plugs into the stock wiring
no cutting or soldering or anything

it uses the same value's as a regular 3 bar sensor

305 : 10.33 is what i have been using for every sensor i have setup

I know this is a older thread. I just bought the EFI 3 bar map and it does not fit like the factory GM 1 bar that I have in my truck intake. Why is there only one clip provision? I emailed them for a answer but I figured Denmah will know. I put a wire tie around the two clips to hold it but that is just not right. Thanks

that is the LS1 style map,

you have a truck intake and a truck map sensor

just plug the map hole, and bust off the barb on the passenger side of it and connect a vac line to the map, much easier, im not a fan of the wobbly stock map sensor plugs at all with the skinny arms holding them on

this is the truck style

I bought the same sensor earlier this week and just got it. I new to tuning, where is it that you change the values at? I'll be using your base tune Denmah from your wiki page that's on the 80# injectors for HP tuners. I'm assuming it's already loaded on it?

denmah

iTrader: (2)

if its a 80lb 3bar SD base tune then yes. its already changed to 3bar sensor

Thanks Denmah, I put a small wire tie on it and it seems to be tight. Just wondering if my big ebay gt45 will blow it out?

I got one of these sensors last spring and it never did work right. Used denmahs set points along with someone elses and it always just read like 110 kpa at idle and like 70kpa with key on engine off I think it was.

Maybe just a bad sensor who knows. I never did return it even tho they offered a full refund. Just went and got a cobalt ss 2 bar instead and set that up. Worked just fine..
