------, no map sensor we use returns 5V. http://not2fast.com/electronics/comp...P_12223861.pdf Thats the GM 3bar spec sheet. Notice how it doesn't return 5V. Vo = Vs(.00318*P - 0.00353). P=300KPA Vs = 5V Vo = 4.75235. The spec sheet says the absolute max at 304kpa it will return just over 5V, but with the amount of accuracy claimed in that spec sheet, I'd say you are looking of a return at 3bar at about 4.8V based on the formula given and the claim of the absolute max being 5V. Using simple averages agrees with the return of 4.8-4.9V. So Joseph, I'm a dumbass?

I'm well aware the Honda map sensor doesn't spit out 1.8bar. I'm also aware that most will read up to about 10-11psi(closer to 11 according to Honda's spec sheets and logical assumptions). Your total confidence in your numbers is laughable though. I'd barely feel comfortable using a number with with 3 sig figs let alone 4. Especially when talking about sensors that are nearly 20 years old.

My comments about pressure is simple. When people think about psi they think about guage pressure 9 times out of 10. Using it in an absolute scale where you define what is positive and negative pressure with the psi unit gets fishy and lots of misunderstanding comes about. Thats why it really doesn't work. It's like the idea that Americans use lbs for mass and weight. It confuses the ---- out of people when you start talking about density. Using different units allows people to detach themselves from what they are used to and make accurate connections.

It's a +/- 3% variable sensor. Now, what's that work out to? :1

Yup!

Since Honda's service literature go to a red hair over three volts, and logical ASSumptions aren't Joey with a voltmeter and a pressure source. You can call it 10.6 psi.



The repeatability of the results I got off of a half dozen sensors, and how often Honduh MAP sensors ---- the bed, paints the real picture. BTW, where'd I get to four significant places? At no point in time in this thread did I claim four significant places. Real world vs Inqyfag's revisionist accusations-always-changine song and dance based on zero experience.



Oh, I see... just because most people are stupid, you are correct.

The precise meanings of systems of measurements used by scientists and engineers should not be twisted to suit the limited intellectual grasp of a generation of illiterate, innumerate, TV watching, mentally absent fast food eaters.

Please define for Joey: "PSIA," "PSIG," and "fist yourself."


Uh, so ------- what? It's a pgmfi.org wiki entry written by Rass. You want it to prove something? How about I get Rass to post up that he defers to me in this matter?

Hey, what happened to your original supposition that Joey LIED? Cough it up, woman, some of us are getting bored with your mouth.

Read data sheets much? Its an 8% allowable error at 3bar. So yea, +/-3%. Its 4.7% allowable at best ------.

Your word isn't proof Joey. Lets see some results from some of your projects. You rambled for months on water injection and months before that about your ITB projects and the list is endless yet has anyone seen those projects other than Trav-*** or one of your other buddies? Obviously huge sucesses. I know the Honda info only goes up to about 1bar. I posted the link remember? Most people who have half a brain look at said data chart and compare it to others and note the offsets and figure that the sensor will only output about 4.8-4.9V. Doing the math you get 10.5983675psi. I know your numbers are quasi correct. Thats not why I bust your *****. I bust your ***** because you feel no need to validate what you say.

Where are these results? Where is this data? We are just supposed to suggest your ADHD self proclaimed drug using self did the test properly? We know you are smart, but I wouldn't trust your attention span for even the most simple of tests. So again, where is the data? Where is the proof? I got 4 significant figs from the same place you got 3% error for the map sensor.

PSIG= gauge and I'd assume PSIA = absolute. The fact of the matter is, regardless if you think so, psi headers when talking about absolute pressure sensors confuse the ---- out of people. Talk to most people who have aftermarket turbo setups about the difference between absolute and gauge pressure. Ask them what a bar of pressure is. Ask them what an atmosphere of pressure is. The conversion from inHG to PSIG to PSIA is queer and far more difficult to understand than bar/kpa.

*****, if you only knew.

Where is the data proving your data?

Are you mocking jd's posting style to sound intelligent? Using words like "said". It doesn't work, it just makes you look like a tool. If you want to roll provide a valid argument, please redo jd's experiment in a controlled environment and document all variables. And don't say "Well JD didn't document all variables, blah blah blah". He probably did and theirs no reason for him to regurgitate every ------- bit of data that came from his experiment in expectation of some douche bag coming out of the woodwork to challenge him for a few extra pixels on his e-*****. You're obviously just following him through threads trying to demean him, while he minds his own business because you see him as a challenge, or a threat. All you have done in this thread is proven that your critical thinking skills are almost null, and you have no ability what so ever to manipulate an argument to try to work your way out of it. If you want to stir up some ostentatious ***, pseudo-intellectual ---- storm, please ---- off. We don't need that bullshit here.
