Replaced the injectors with some brand new Deatsch Werks 740cc injectors. Car idles at ~ 1 lamba at 17ish ms master fuel, which seems still wrong. From what I work out the number should be closer to 7ms. Using this file (plus the tune and log attached), I've come to see the injectors are 370cc ish. Struggling to think what else is the problem. I updated the dead time with the supplied values, is there something else I am missing here? lognewinjectors.llgx newtune740cc.pclx

Thanks @Adamw, out of interest how did you determine this?

Wow time flies. @Adamw See attached logs of car idling + map. 33ms master is what the final number ended up being. I have affirmed fuel pressure, and smoke tested the system. These injectors may potentially NA injectors from this master ms value. idlewithblip.llgx basemap12_9.pclx idlinglog.llgx

@Adamw it was about 3ms at 14.7 afr.

Hi guys small update on this one. Got all my parameters wired in IAT, fuel pressure temp etc. I have it idling at 14.7 AFR at full temperature. My final master fuel ended up being 38ms.. My fuel pressure was perfect for the entire time @43psi . Thinking I got sold dodge injectors.

Hi guys, Got a 300zx running link with nismo 740cc. Got it idling at near 14.7 However I had to use master fuel at 25ms, is this value too high? I am not sure if there is another issue present as others seem to have a much lower master fuel. I've attached the map and a log. Cheers. fuel25.llgx 300zx.pclx
