Hi i have a lsvtec turbo setup. right now i am using a missing link for my map sensor and i have been thinking about getting like a 2 bar map sensor or something. my question is i plan on running around 10 psi boost and i dont know what size to get i see they are rated from 2 bar to 4 bar, if i got one of these map sensors and only ran 10 psi would it work right? also what brand is good , and i am tuning with crome right now but i am planning on getting hondata s300 so i need one compatible with that.

 

stock map sensor is 1.7bar.

1.7 bar - 1 bar for vacuum
= .7bar
.7 bar = 10.1526416 psi

Set a power goal instead of a boost goal, they dont sell parts with boost pressure in mind but they do for hp/tq.

 

Honestly, just buy the Hondata 4 bar map sensor and be done with it, it will work fine with low boost, and you wont have to do any wiring.

 

If you're using a missing link, that means the stock 1.75bar MAP is still there, it just can't see boost with the missing link attached. Take it off, and you'll be able to read to 11psi. Later if you intend to go big, you can always upgrade.

The 'problem' with upgrading now is that you'll need a retune later anyways if you only get it tuned for 10psi now. Its also ~$120 for a 4bar, which is money wasted until you need to increase the boost.
