Enki replied to the thread Signs of excessive backpressure?.Correct. In a PI system, the flow is static for both the injectors and (electric) fuel pump at 100% IDC regardless of RPM. In DI, RPM... -
brandon19 replied to the thread Signs of excessive backpressure?.I don’t know the specifics of how our fuel system works but at higher RPMs there is a lot of fuel flow from the pump that isn’t being...
-
Enki replied to the thread Signs of excessive backpressure?.That...actually may be your issue; you might be momentarily pegging the sensor, causing either the injectors to fail to open or the ECU...
-
brandon19 replied to the thread Signs of excessive backpressure?.Yeah hopefully, I will try that later tonight. I will also lower my fuel pressure targets back to stock because I'm already in the...

Enki replied to the thread Signs of excessive backpressure?.Oh it's VT. I've had weird issues with hitting load targets on VT, it always hits under for some reason. Looks like my maps match what...

brandon19 replied to the thread Signs of excessive backpressure?.From my understanding the Injection Pulsewidth and the Base tables are new which are used to calibrate for different injector sizes when...

Enki replied to the thread Signs of excessive backpressure?.Check the Injection pulsewidth related and the two below it, as well as the max injector dc (which is probably the one I'm thinking of)

brandon19 replied to the thread Signs of excessive backpressure?.Nah wasn't like that, it is more so 1 or 2 quick hesitations after the other rather than a limiter one. However, in that video my MPS 3...

Enki replied to the thread Signs of excessive backpressure?.Was it like this? Specifically first gear: To this day, I have no idea what that was; only happened with the AP and only in the lower...
-
brandon19 replied to the thread Signs of excessive backpressure?.Alright, so I tried 0.024" gap and the misfire / break up still happened. I tried the OE plugs again (ILTR6A-8G) and it was still...
-
First off, your WGDC is falling as RPM increases. As RPM goes up, potential airflow does too, so having reduction in commanded energy to... -
Enki replied to the thread Signs of excessive backpressure?.Actually, try dropping your gap to .024 first. Step colder really *shouldn't* be an issue on pump gas, but it still might be. Much...
-
brandon19 replied to the thread Signs of excessive backpressure?.Okay, I'll go grab some NGK ILTR6A-8G and see how it goes. What gap should I set them to?
-
Enki replied to the thread Signs of excessive backpressure?.Every setup is different though, and if you have misfires up top, that would absolutely explain the power drop. Plus there's a lot of...

brandon19 replied to the thread Signs of excessive backpressure?.My understanding was for every 100hp or so over stock power, you should go a step colder. I also assumed because Cork Sport sells the...
