Need help with startup enrichments and afr's
I've got my car running, but it is hard to start up. To get it started I have to cut the fuel pressure back to 20lbs, once started i move it back to 40lbs and it idles great. After warmup when I go into boost, around 7psi it get really rich around 10afr give or take and sputters(I'm wanting to run 12lbs of boost). Also my aem wideband guage readout is fine, but the one on my megatune is showing up around 2-3afr. I know that it is wired up right, I was just wondering if i need to change some settings in megatune. Finally, my megasquirt shows the temp in the yellow at 210 is that right, or do i need to make some adjustments.

larger injectors + your current cranking table = "To get it started I have to cut the fuel pressure back to 20lbs, once started i move it back to 40lbs and it idles great"
larger injectors + your untuned fuel table = "when I go into boost, around 7psi it get really rich around 10afr give or take and sputters"
