Obviously it has a vacuum reference, but there could be offsets caused by pressures on the case. I know for a fact that if you say tighten the screws that hold them too much you will create wrong readings. Just a thought before you bury one in epoxy or something. I assume you guys are talking about the SMD type ones? Fred. |

Re: Where you mount your moto map sensor
Your history also lists you as the biggest whiner in teh whole world, so... :l
Freescale sensors (all rights sold to them in 2006) need that P1 hole/port (depending on the package type) exposed to air. The readings actually can be skewed if the case is distorted, since the way they work is measuring how much that 'die' flexes. Cementing it in epoxy in the sealed OEM housing will not get you any usable readings, since the epoxy and case are too rigid. Also they have gauge (atmosphere vs input) and differential (input 1 vs input 2) sensors, which won't work on cars. You can use any sort of small case, as long as it is totally sealed (besides the vacuum port) and can hold hold the boost level you plan on running. ---- you could even use a condom and a rubber band... :1 |

Re: Where you mount your moto map sensor
I'll vouch for that.
No one around here knows enough about Honda's to even know what a MAP sensor is half the time. Shave the VTAK off the valvecover and you're good to go! |

All hail JD, oh creator of the "stock" MAP sensor. :y Definitely never saw that thread on PGMFI though. |
Re: Where you mount your moto map sensor
Well, you are a brighter than average egg and it does seem like a logical conclusion when you think about it. It's a sad reflection on everybody else that it hadn't been done sooner.
