Map sensor voltages
i found a table on hondatech stating what voltage was what pressure on the standard honda map sensor but cannot find it again, i need this for the user input on my zeitronix, help anyone?

Re: Map sensor voltages
turn your key on, engine off...start up your zeitronix datalogging software to see your voltage at 0vac....Mine was 2.75v. Your`s may be different due to altitude.

Re: Map sensor voltages
that gives me a base for the high end of the scale, but i dont know what the voltage is at high vacuum, so it wont be able to interpolate and give me the correct value

Re: Map sensor voltages
ok....
How about what your vac is @ idle? Idle is going to be high vac obviously... .1v = 1" of vac so here`s what I got: 0 vac = 2.75v 1" = 2.65v 2" = 2.55v 3" = 2.45v 4" = 2.35v 5" = 2.25v 6" = 2.15v 7" = 2.05v 8" = 1.95v 9" = 1.85v and so on. Oh yeah, I had a thread like this awhile ago...I just went ahead and figured it out on my own. Wasn`t that hard. https://www.homemadeturbo.com/forum/...?topic=46107.0 |

You should find the number for KOEO on YOUR CAR before you do any tuning because you want to be as accurate as possible...because you are tuning YOUR CAR...right? ...I am right or am I way out in left field here...jesus christ buy a clue and tune your car already. |
