does it pop or miss or just wont rev past 3k, have you checked that all the plugs are on properly and tight

arbinder

when runnig un plug your map senser and c if the engine note changes,does it smoke at all or anything,also what breather are you running as the fiesta runs with the little one way valve in is the valve the right way round

studabear

another point is how are you measuring the engine revs?

s1 or 3i rev counter will only read half iirc as ofac/ofab's wasted spark

arbinder

im using xr3i efi clocks

studabear

cool, reading should be correct then

arbinder

with the map sensor off the engine sounds the same i think but when rev trys to cut out doesnt smoke and the breather im using is a fiesta rs turbo and its all fine

when i dis-connect my map senser the engine note changes and it sounds like its trying to cut out,have you checked the one way valve on the breather too,also can you hear your turbo winding up at all as your exhaust might be slight blocked

arbinder

turbo has been set to no boost at the moment can it be the cps ?

Have you definitely got the correct OFAC map sensor? They're listed on Ebay all the time with an XR2i sensor which won't register any boost.

The XR2i ones are rectangular. A proper OFAC one is sloped on the right hand side.

Will it not rev past 3000RPM when it's out of gear? Or is it only when you are driving it?

What happens when it won't go past 3000?

arbinder

got the right ofac sensor it wont rev past 3k on stand still dont no about driving it yet as im just finishing it
