anyone ahave any ideas, my escort on megasquirt managment runs sort of ok but i keep getting hesitation and the car suddenly judders forward every now and again seems to of got worse today?

i have bought some injector cleaner but it hasent done anythink as i thought it might be a dirty injector?

anyone have any ideas what would cause the car to judder every now and again.

who mapped it ?

rsguy

it was mapped at northampton motorsports, it had the same problem when it was being mapped, juddering, they said its not a ecu fault its somethink else.

so they said however im not sure what would cause the car to judder every now and then

whats juddering engine or clutch/box ? when does it do it ? eg on acceleration / light throttle / stationary etc

throw us some more clues

rsguy

the engine is juddering, its like when you have a blocked injector, like theres power then it stutters then ok again, it happens most the time now,

it does it on acceleration / light throttle / normal driving and also when engines idling on tickover it stutters every few seconds??

GARETH T

they dont know how to map the transients

Rick

You need to get a data log of when it's doing it.

rsguy

well its practically doing it all the time even on tickover?

so do u guys reckon its a megasquirt problem? or ignition? or maybe fuel?

as to be honest im not happy with northampton motorsports as they said they dident know why it misses a beat every now and then, they said its not a ecu fault however they still charged me for a mapping session despite them knowing about this problem and me driving home with the car stuttering every few seconds.

Rick

no way we can tell what the prob is without more info. What car is it? What software is the MS running? etc etc

rsguy

the engine is a 2.1 zt, running a v2.2 ms, MSnS -Extra 024 series of firmware

Rick

you need to get some data log files posted up, then we can get an idea of whatr's going on.

my guess is it will be fuel / pump related.

PS Rick.. thanks for your help today

Rick

My pleasure mate Enjoyed working on it

Did you buy it off ebay from a company in loughborough? cant remember the the company name.

rsguy

yeah mate u mean mtech, can i ask why??

rsguy

i also noticed today that the 3rd led on megasquirt unit (far right one) lights up everytime the cars kangerooing or playing up?

so maybe this indicates a problem? what is the 3rd led in conjunction with?

will get some datalogs posted upp later im gona connect it up today.

GARETH T

isnt the leds programable? so you will need to look into your software to see what turns it on

rsguy

from what i can tell the far right led is d19, and from looking in megatune you can program it to either acceleration or spark output b.

so maybe this leads to some clues?

what you think guys ?

rsguy

one thing i did notice through which is weired,

when i took my plugs out today they were back & sooty



even more weired is as soon as i changed ht leads its seems to be running alot better and only kangerooing every so often???

maybe that points to some clues??
