i have heard alot about these 3 bar map senser wot is it and wot do they do

 

MAP Stands for Manifold Absolute Pressure, It sends a signal to the ecu regarding how much air is entering the engine

 

As above but the 3 bar refers to its pressure range.

This is 2 bar boost + 1 bar atmosphere = total 3 bar.

1 bar is the same as 14.5 psi roughly


You can ONLY fit one of these if your ecu chip is programmed for it.

The standard car one on a sierra for example is a 2 bar sensor.... 1 bar boost + 1 bar atmosphere


Basically, you change this sensor to allow more boost to be used.

 

i got one for sale if anyone interested

 

LOL @ rst Watch out for the gestapo

 

Sean2k - are you the same fella that bought an RS500?

 

the what? lol

 

Look here .... http://en.wikipedia.org/wiki/Gestapo

 

 

how can you tell if the sensor is standard or 3 bar ? -

 

Generally... Standard sensors are totally black and the 3 bar is black and grey.

 

standards are usualy all black, 3 bars are black base with grey outer, prob other ways but thats the easiest that i know of

 

cunt you got in 1st

 

LOL, dont you just hate that when it happens. I am the one who is usually second

 

boo

 

check if it has 3 bars on it

 

ok - will check - I have question for all - bog standard escos or blinged up escos engine, which would be the more desirable as Im in a dilema - not sure which way to go as car ive just bought has a new ford lump standard done 2k and a few samco hoses but not all also has a shiny breather tank and a k &n apart from that the rest is standard. do you carry one and finish the job or go back to as ford intended?

 

gazm,
When i got my escos I kept it standard for 6 months... then I just could not resist modding it !!!

It really is down to personal preference ! I didnt like bling that much myself but all the mods were done for power !

 

what year esccos, is is a small turbo or big turbo?

imho go for stage3 kinda power, it's cheap and reliable if well maintained.

 

hmmm, I know what you mean mate, but when you see a totally standard car they do look the dogs, specially if its looked after, and they do seem to fetch good money if standard these days, but someone sort of had a go at moddin it but never quite got there, saying that some of the member cars on here look superb when done.

 

Jim

Its a big turbo. new out of the crate from ford yb - not rebuilt and it has 803s and a weber ecu ? not the standard ford one,

 

the standard cossie large turbo ecu was a weber !!!

Hard to believe ford would supply 803's. I dont think you will find its original !
Where did you get it ?

 

yeah the injectors wouldn't have came from the factory, if its runnin greens its prob st3 already in which case it should already have a 3 bar in it, what kind boost does it run, that should give it away?

 

^ ditto

also is it fast or slow, as standard cossies are slow and stage3 cossies are fast

 

It should run around 21 to 23 psi depending on turbo and chip.
That will give it a nice kick up the ass ! about 310 to 330 bhp.

 

No youre right - the greens were put in after by the garage that put it in for the owner , the engine was standard internally, I have been told that the gasket was a group a when put together,. the car was then sold to the garage (tgr nmotorsport) who put the YB in, I had it from them. I have heard it run but have not driven it as yet, as the rads are not in, and needs finishing so thats why wondering which way to go with it.

 

Standard normally has APS 02/03 and 3 bar has APS01/05 ...

 

The cossie was on ebay - yous might have seen it - petrol blue with oz alloys and morrettes. They were considering selling as rolling shell - interior and engine all separate !! couldnt have that.

 

ok thanks Martin.

 

Have you not seen Allo Allo?

 

thanks lads most helpfully

 

you still buying a 500?
