Title: Turning off Error Class's for Systems that "dont" require readiness Post by: bamofo on October 07, 2020, 06:51:44 AM I understand why we do not just turn off error classes for Emissions related systems, it will just sit at incomplete or fail.
Question is, for things like Intake Flapper systems on some of the MED9.1.1 systems like the RS4... What is the harm in turning off the error classes to those? Rather then coding out the flapper system all together... Looking for pro/cons... or just guidance so i can fast track some work i am doing now, or learn more about these systems to code it off correctly. Thanks in advance Title: Re: Turning off Error Class's for Systems that "dont" require readiness Post by: _nameless on October 07, 2020, 10:43:46 AM Hiding p codes does only that. Runner flaps when deleted need a lot of fine tuning in cold start tables at the very least. Not to mention you just tottally changed the inlet path of the incoming air. End result will be weak feeling mid throttle without retuning. Really no advantage deleting them with stock intake manifold and turbo. With large(gt30 or larger) turbo and a custom sri thwn yes runner flaps will need to be deleted

My real question is why should i not just "hide the p codes" in this situation. is there a reason to fully learn the system and disable the components, monitoring, and any release CWD words that go with it? or is that a waste of my time. I do not want this thread to be about intake flaps, i just want to make sure i understand systems that are not related to emissions and how i "should" be going about coding them out / Benefits to either.

You never know w/o reading the FR thoroughly, and even that might not match with the version of ECU you're using. |
