MG MGF Technical - MGF 1.8i can't really stop the oil amount supply
|The rotational speed reaches 7000 the above of rotating should be able to stop the oil amount supply.|
But my MGF 1.8i can't really stop the oil amount supply, why?
Help me .
|George, I'm not sure what you mean. Could you explain in more detail please?|
Only 8000 rotation rate in the speedometer.
But The rotation rate exceeds 7000, MGF's ECU should Stop supporting the oil.
But My MGF can not ,Why ?
Or How do MGF rotation rate to stop support oil ?
|I think this is the engine cut-out not working when over-revved. It should cut the spark/fuel.|
For oil read Peteroleum/gasoline.
If the rotation rate exceeds 7000, the ECU should cut the fuel. The engine will not working.
This is an engine protector of MGF.
But My MGF CAN NOT function,Why?
|Sorry , ECU is ECM , I write worn.|
"To prevent damage at high engine speeds the ECM
will implement fuel cut-off at engine speeds above
approximately 7000 rpm. Fuel is reinstated as
engine speed falls."
My MGF 1.8i Can not cut-off , Why ?
|Don't know for sure but the rate at which my rev limiter operates indicates an electronic system not a fuel-off. |
Assuming this is the case, I would suggest either your ECU has been reprogrammed or replaced with an after-market version. The other possibility would be a faulty crank sensor, but I would have thought this would cause problems at lower revs as well.
|I wouldn't suspect the crank sensor, as that one is very important and required even to start the car.|
George, could you tell us more about your car (MGF type, year, etc...) ? My MPi has a rev limit at 7300rpm, as it has another ECU/ECM.
