3 BAR MAP Sensor For Various GM Models with Connector Pigtail

Using this to send my data to a FAST system on my turbo car it works just fine.

Tried to use this on a twin turbo Coyote setup with Holley HP Efi. Engine would backfire and start running lean. Looked at the data log (pictured) and saw the MAP value erratic and capping at 100kpa. No Bueno. Why advertise 3 bar and sell a 1 bar unit? That's how engines get destroyed. Steer clear of this trash...

The pins of the supplied connector don’t fit in with of the sensors I purchased. I had to de-pin the connector and force them into the sockets. Then I could reassemble and install. After reading the reviews I think I’m just going to return them.Update, I moved it up to three stars. I was able to get the connector to work and tested the two units. Both sensors supplied the correct voltage for the vacuum I supplied.

Absolute garbage, save your money and just buy a genuine sensor. HPT shows that readings are erratic and incorrect, even with correct scaling for a GM 3bar map sensor. Car would barely idle and die as soon as any throttle was applied. Replaced this garbage with one from a known good company and all the problems went away. This part reading incorrectly could absolutely destroy your engine, do not take the risk and just buy something better quality.

I've used this on a single turbo LS swap. The reading on HP tuners is slightly off from what it actually is.

Pig tail it comes with is trash and doesn't even fit properly! And the sensor itself was just a piece of plastic with pins! Installed and truck wouldn't run properly, pulled it off and looked, turns out it was molded plastic!Can't give 0 stars for review, so 1 it is!96 chevy s-10

Not what promisse

Plug will not fit into the map sensor so I use the old plug with the new map sensor truck kept dying but it only cost me like $4 probably why they're $40 everywhere else but Amazon had it on my porch just like always and right on time
