guys i have know knowledge of that it dose i know my car has onebut what dose it actely do. i know what a knock dose. dose it just reat speed, pressure of the engine that sort of thing..

ps. damb it is hard to try and plug in that wire one your engine is all in.

Anyway, a map sensor, does just that. *Manifold Air Pressure* sensor (i think thats right), anyway, sensors how much pressure (or vac) is in your manifold.

this then has a map within the ecu in which it can pick out, dependant on boost / vac, and inject the correct about of fuel (well, if the ecu is tuned well lol). MMMM to incorrect fuel maps _b

yep that's right Cozmo you're right about the name - senses the manifold/boost pressure - sends message to ecu - etc

Manifold Absolute Pressure, is what I though it was

thats what i was gonna say, until i thought *why is it absolute*?

heyman give me a brake i just plug in the wires and it gose. but i'm unshore if the wire i cant find were it gose is for the MAP. it gose with the wires that go down to the altinator. and once everything is pluged in there is still a wire hanging with the bunch. were dose that go. its justa little slit 1 that'll push on somewere. but i dont know were

by **deaf_rattle** » Wed Apr 06, 2005 3:37 pm

and you are wanting to twin charge an engine?

i think you need to come to terms with the basics first man.

point is, we cant completely understand what your saying, bud.

seriously man, saying *theres one wire left, where does it go*... dosnt help, where is the one place that hasnt got something plugged in?

we can answer questions we know the answers to.... we cant answer questions like *whats behind my back!*

i think they're interchangable. our tutors at weltec use both of them

Whats the difference between a gudgen, a piston pin and a wrist pin?

by **[V8ROLA]** » Wed Apr 06, 2005 6:53 pm

nothing

there is a difference between a boost MAP and N/A map sensor tho, one reads vacuum and one reads boost

you cannot run a non boost pressure reading one on a turbo/S/C setup.

this is exactly what I meant in your first post about how I doubt you have the intelligence required to twin charge anything, even a car that's already twincharged! Seriously, you must be very naive if you think you have the skills required to plan out and then implement a workable system. But if you're lucky you might fluke it, or someone else might do it all for you.

by **dragg_racer666** » Wed Apr 06, 2005 11:17 pm

hey man you are for getting i amnot doing the twin chargeby myself. a machanic is working with me on the project. he has done it befor and is keen to try another one.and i do know anything about engines (machanicaly) i just finished rebuilding my 4agze. i just arn't all the way with the technical electrical crap. this is my second modern car i have owned so its a change. i'm used to working on old skool holdens vallents and chevs. which dont have electrical shit. just a distributor.

The wire that is hanging is beside the altinator, its not for the altinator. and i cant find any were for it to go.

i hope for your sake that your mechanic friend is alot more knowlegable than you.

:lol:

I hope you don't work as a mechanic anymore, it's people like you who screw up car owners like me, who take the blame coz of the crap knownledge and work done by the people like you.

by **dragg_racer666** » Thu Apr 07, 2005 3:10 pm

hey bro i never in my time $&#$% any ones car. and yes the machanic that is helping me is good. he is the owner of a popular place in town. and thereason i'm not a machanic anymore es because i went into the forces. but i'd neva want to be a machanic again any way. technology in cars is getting so advanced so fast and when i was learning half the shit that is in cars now was never there.

by **CozmoNz** » Thu Apr 07, 2005 3:11 pm

So, whos this mechanic? im in dunedin

by **Lloyd** » Thu Apr 07, 2005 6:49 pm

Geoff Christie had his twin charged rally Corolla so that would be my guess of who it is.

by **dragg_racer666** » Fri Apr 08, 2005 2:24 pm

yes thats who. he now has a twin supercharged lexis V8 in a fxgt.
