injector voltage

[schumy]

I have a 95 gsx and it will start up fine closed loop 02 will cycle and I'm around 14.7 but as the engine runs the ratio goes leaner then maxes at 19.5 starts to stutter and I have to keep it running by the gas pedal ...does battery voltage at around 11.0 give injectors a problem?? I have replaced the alternator and battery ..and I have heard the the dsm charging system is not that good??

What are you using to log/tune? Can you post a log?

If you have only 11 volts your charging system still isn't working.... .

I'd be guessing in the dark with out more info of what's going on... .

But these are some things that come to mind off hand

Incorrect deadtimes per voltage set in the ECU(running after maket injectors), a fueling problem,AW/b o2 sensor going out with narrow band simulation enabled, Or some kind of incorrect global fuel setting... all I see in your profile is a SAFC keep in mind when pulling fuel out the car is reducing the Airflow(via a Safc) to the ECU is going to affect your load seen by the ecu an affect timing as well... .

More info will get you more accurate help...

O sorry I edited it junked the safc and got dsmlink v3 must have forgot to hit save
