HELP !! 4 - 5 RPM 318i

[millyboy]

my m10 318i at 4 to 5 RPM is like wanting more fuel or air and is hesitaing and wants to rev more is that normal ? or do i need somthing to replace or check ?

[Alex]

could be rotor arm and/or dissy cap, it might also want a good service

[millyboy]

hey thanks .. it might be the dissy all together .. cuz the motor has had a fully rebuild and the head fully serviced decked the head to the max . so theres really big compression um but the dissy was a little rusty and i put a new rota button ... grrrr i dont know what eles to check...
i only just finished putting a whole new computer ,harnes, well all of the injection set up ..
hmmmm

[Alex]

you could try a new one

is it mapped to accommodate that high compression?

is it mapped to accommodate that high compression?

you cannot remap the 318i m10 ecu

[millyboy]

No i didnt think of that , do you think its better i change the coil to a bosh gt40 12v and upgrade the injectors to 199cc and get a sports air filter ?

[Alex]

sports air filter ?

that wont do anything


are all the ignition leads pushed in properly ???????

[millyboy]

yeah ... there in ok ..do u think its the cataletic .. its smaller than the normal one thats goes with the car ? .. i might punch out that stuff and try it . so its straight through ?

[Alex]

not sure, i dont really know much about cats apart from they remove nasty gasses, not sure if it would affect the running of you car

you might aswell remove it
