Can you share your jb4 settings. Having an issue with my setup. Seems to be coming on but not injecting

If you get a "fuel enrichment" signal the JB4 is requesting PI. If nothing comes back under "meth" from the controller then likely a physical issue. On the other hand if no "fuel enrichment" request in the log that points to a setting disabling it.

Same guy emailing me? Log shows a PI request, and a return from controller. So PI controller is all good.

PI METH IMHO requires a pressure sensor on the rail so you can verify the pump itself is on and running, and use that reading to factor in to the injector IPW. I know Fuel IT sells a kit with their setup. If you don't have a pressure sensor, you need to somehow check it to see if pump is even turning on.
