I have finally started the duratec in my fiesta

it has a start up map on the ecu

when i try to rev the car it doesn;t like it and will come close to cutting out, anybody have any ideas what i need to do, i thought it should rev on a startup map, or do things need adjusting?

 

The map is most likely a million miles out.

 

Or maybe cam timing?

 

engine has never come apart

wont be anything internal

 

Had same problem. Connectors on flywheel sender was correct according to manual but after switching I got it to rew upp. Still have lots of other problems with the system so if anyone has any good maps I would happily test them. Duratech 1,6 sigma engine.

 

Surely omex have a closer map in their library ?, worth asking the they can email it to you to dowload on pc/laptop then onto ecu.

What is the spec of the engine?

 

What do you mean with spec. English is not my first language so please use basic english

 

spec is short for SPECIFICATION, ie what is the engine cams, headwork, block etc etc basically what has been done/added to the engine to make it different.
