rough running/injectors 740cc
just fitted some 740cc injectors to my 93/94 plate impreza,it now will not idle and runs rough under light throttle,revs up fine,i am guessing that i need to have my power fc adjusted as i had 440cc fitted before,i am booking jolly green monster to come and map it but didnt want to get him all the way to my place to find that i have a knackered set of injectors,guessing its running rough due to excess fuel being dumped into the cylinders due to them being alot bigger,car ran fine before even tho i have not had the power fc mapped to my car since i brought it,just been trying to get all the mods done before i had it mapped

ahh righto, might have been better with 550's cos the 740's are gonna be way way to big and might suffer from slower responce times.
but none the less should think untill its mapped will be all over the place as far as fueling goes

Using the commander go to the injector scale setting and turn them down from 100% to around 65% , this will get you in the ball park for a minute..
Then stick to the speed limit till it's mapped and you will be fine...

Either fit your old injectors back until it gets mapped, or get the mapped tweaked by some one who knows what they are doing.
