Lower my fuel pressure to help w/fuel injectors.., ...being too large??? Options

[Mueller]

Running 2.0 injectors on my stock 1.8, new fuel injection fires all 4 at one time (batch), I have a feeling new injectors are too much....anyone lower their fuel pressure to compensate for large injectors??

I'm wondering how low can I go yet still retain a nice reliable pattern?????

is there a removable programable chip in these ecms? or is there some manual pots or something in there to do what you're talking about with injector pulse duration and timing.

I hit a button on my laptop computer to change the pulse widths and everything else for it (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/type.gif)


It appears I have an ignition problem, I'm still getting the erractic miss running just the cdi and distributor taking the Link off of the duty of controlling the ignition...I only had time to pull the plugs last night and boy, are they filthy, looks like I dipped them in charcol dust....my next step will to clean them up, gap them and try it again. If I still have the miss, then I'll remove the CDI box from the equation.

For my pulse width at idle, I am at 4.5ms, stock fuel pressure regulator, fuel pressure set at I think 32psi

I've run these injectors with my D-Jet on the 1.8 with no signs of problems, so I'm a little confused as to why I'm having an issue now, but it might all be ignition related now that I am headed down that path of troubleshooting...thanks all...
