After looking at the vacuum switch options, I felt like there must be a better way. Since I have worked with arduinos previously, I searched and came up with your posts.

I would love to get a copy of your gerber files and the arduino sketch. I looked over your parts list and I am thinking I might be able to use an OEM 1bar MAP sensor in place of the NXP sensor you used. It is a 0-5V sensor, and I already have one handy. Any thoughts on that sensor?
Sounds like a fun project you've got there. I'd be happy to share the files with you. I received your private message, so I will send you an email shortly. I had to order five PCBs, so I've got four extras. I can drop one in the mail to you, if you'd like. If the MAP sensor is 0-5V, then it should work.
