i put some big injectors in race buggy but they where to big and overfeuled is there anyway to slow down the pulse width to get them to move less feul ? anyone messed with thiss ?

Close the loop with an O2 sensor?

 

There might be a limit to how much adjustment it can make to the PW.

was thinking of a way to slow down the pulse

megasquirt engine management?

yes thats a good way to go but expensive for a mud buggy the electronics get wet and muddy alot not shure how well the mega squirt whould hold up to that but it looks like it my next step i have it up to 550 cc injectors now with a 20 shot of nitros seems to work good i got a fogger that gives feul and nitros so i can add extra feul with the nitros and jet it accordingly
