Map sensor

Silly question but where do I buy a 3.5 bar map sensor for an N54?

You'll have to get the adaptor harness from BMS: http://burgertuning.com/N54_JB4_upgrades.html

I'm seriously trying to understand this...how does someone stumble onto the entire concept of the 3.5 bar sensor, understand enough to know they need one, but then not figure out how to source one It's the easiest part of the equation.

That's the equivalent of finding the cure for zika and being like "ya'll know where I can buy some syringes at?" lol

isn't the 4 bar cheaper and able to read higher boost?

Thanks guys. Thanks the extra info also. Some people just can't resist. As for the 4 bar, they can run more boost but from what I have heard they have had some small issues with them and they are slightly less accurate. Thanks again for your input guys

I just run the 4 bar sensor and adaptor from bms. Works great and it's cheaper.

Because it uses the same voltage range but reads a higher max boost, so it's less precise. I guess you could imagine an image file of a given size. You could then scale it up 200%, but it won't be any clearer.
