id like to know if i can tell if i have a 3 bar map sensor on my car,how will i check,
its a series 1 rs turbo efi ofab
also what fuel pressure should i be running on beiges 1.8zvh

i know it will need setting up though its not on the road at present and keeps black fouling plugs so id like to get it something like so i can get it mot'd then setup cheers guys

also im led to beleive i have a cosworth fuel pressure reg onmy efi rail,how will i know?

cheers again

 

they are normally grey mate were as standard ones are black

 

thanks for the reply,
i have dug out my engine work receipt from years ago when i was hopeless and knew nothing,it doesnt state a map sensor but a used cosworth fpr on the receipt
also a phase 2 chip from msd and new beige injectors
will this chip be suffice for my 1.8 zvh? still on beiges

 

part number will tell you for sure, post it up

 

it won't work if its a CVH chip.

Also we don't use 3 bar map sensors with our OFAB OFAC Chips.

 

thanks james,the chip is from yourselves in 2007 and states cvh phase 2 on my receipt for my engine builder who originally did efi conversion in my car for me,
i plan on running it and getting it setup by my local tuner then use it mildly then get it on my recovery truck and geetting it down to yourselves to be setup with a new chip,can you rewrite my current chip and set it up or will i need a new chip, ive established its a 2.5 bar map sensor now thanks

 

You need to use the STANDARD map sensor nothing else.

Yes we can rewrite the old chip no probs

 

thats good news then hopefully save me a few pennies,i am definately serious about fetching it over for a full setup just need to get it running something like as its overfuelling and get it mot'd and taxed and i will get it over for a checkover and a proper setup,

thanks for taking the time to reply

 

rolls ran his XR2 Turbo with a 1.8 ZVH on a standard CVH chip for quite a while without it blowing up so it should get the car running. might need a dodgy MOT to get it past emissions mind.

dont go driving it silly just get it up to MSD and get the chip re-mapped.

IIRC those EEC-IV chips are pretty expensive so its agood job they can be edited, not the 10p eeproms that go into cossie ECUs.

i once broke a brand new MSD EEC-IV chip by not following the instructions and plugging it in upside down, felt proper guilty when stu did me another for free as i found out the cost of the hardware was almost 100quid

 

thanks for taking the time to reply,i will get it to my local tuner and get it setup something like then get it to msd,im glad i can have the chip rewrote will save me some pennies,got to be worth the 130 mile drive to blackpool im sure

 

what part number should the 3 bar be? I have a black one which I was told by a reliable source that it is a 3 bar (it is a genuine MM)

Cheers
