ECMlink How to log Crankcase pressure

[Anthony Boni]

Hello.

As the title says, I want to figure out how to log crankcase pressure. I’ve recently installed 2 8AN fittings on the top of my valve cover and want to ensure they are efficient enough.

How would I set up to see my crankcase pressure in a log? If possible. I swear I’ve read it somewhere, but I can’t find anything related to logging CC pressure. Thanks guys.

Check the link below. You can get the idea. Does not matter what kind of pressure you want to log, just change the pressure source.

Awesome thank you. I will give this a read

Great advice from @DSMPT , should be able to use essentially any kind of ecmlink-freindly map sensor and pick a loggable input.

Use a 2 bar map

I was reading Calan’s catch can post and that’s where I initially read it. I knew I read this somewhere! He stated he just ran a boost pressure sensor and T’d off the valve cover AN fitting. I think I’ll do that. Or run it from that alignment hole in the back of the block.

Using either a universal boost pressure sensor or a two bar map sensor, they both wire in the same way as the post @DSMPT shared, I’m assuming. I’m a terrible electrician, but I should be able to figure it out.

Good idea. Do I have to worry about crankcase vapors destroying the sensor?

Shouldn't if you mount the sensor up from wherever you're tapping in, its just a small diaphragm that senses pressure differential, so as long as things can't drip down the line it shouldn't foul out, at least not for a long time.

I’m trying to figure out what sensor to buy/how to install it/wire it. I was assuming I could find a map sensor with a threaded end I could thread into the back of the block via a male 10X1.25 to female NPT adapter. I can’t find an example on how someone has done this outside of calans.

For instance, you can use like below.
Sensor side would be depending on your choice of sensor.

If you want barb fitting.

Looks easier to just go with the barb fitting. Need to find an inexpensive, ECMLink friendly 2 bar map sensor. To the interwebs!
