Eliminating Codes with Enginuity...
I need to pass inspection in the next few weeks and my car just began throwing TGV codes (RH stuck open). Rather than fixing the problem right away and possibly messing up another system that would cause me to fail inspection while I have the intake manifold off I have ordered a Tactrix cable and decided to use enginuity to eliminate the DTCs. After passing inspection I will be doing the TGV delete as well as other engine mods.
So, my question is that if I use enginuity to eliminate the codes will it always show up as system not ready when the codes are pulled (causing me to fail the inspection) or will it pass the OBD-II inspection? I've read a lot of threads asking how to eliminate codes and they only go so far as saying that enginuity or (insert other OS ecu editing software, AP, etc) will clear the codes and turn off the CEL but I haven't seen too many comments on whether or not it stays in perpetual "system not ready" status once the codes are eliminated. If that won't allow me to pass emissions can I use enginuity's Force pass readiness function to pass emissions? I know people don't condone this but This car is my DD (and stock... for now) and I need it to pass the inspection before I go back to college.

Disabling a CEL will not impact any readiness monitors. I can't remember if the TGV-related failures will impact any of the readiness monitors, though. I don't think it does. The latest ecu defs do have a new TGV fix which bypasses the TGV checks completely which is different than a standard CEL disable. |

I should clarify that when I said "disabling a CEL will not impact readiness monitors", I mean that disabling the CEL will not help you pass any of the readiness monitors.

Will cause the ECU to always be in a non-ready state... I.e. the emissions readiness monitors will never be ready? Or, are you saying that the TGV sensors have no impact on whether or not the system is ready... it's only the fact that they are throwing a code that will cause me to fail. Sorry if this is a really simple point that I'm missing... I really haven't been looking into OS ECU tuning for more than a few days. |

OK.. I think I see it now. I just went out and pulled the codes from my car with an OBD-II scanner. It passed all the readiness tests, once with the CEL light off (was off when I started the car this time) but throwing codes 1088,1092, and 1096 and once with the CEL on (came on while driving) and throwing the same codes.
So if it passes the readiness tests with faulty TGV hardware (and throwing the associated codes) it should pass them with the codes suppressed in the ECU. If I had the Tactrix cable in my hand I would just go try it out... but it's still in the mail, so I'm just trying to understand it before I mess with the ECU. Thanks again for your help Tea cups! |

You want to enable the fixes under the "emissions" tab (the ones you have open in the screen shot above).
If you disable the CEL's in the "Diagnostic Trouble Codes" section your readiness monitors will never become ready (even if you have the "fix" enabled in the emissions section). |

The reason you don't have the force pass fix in your "version" of Enginuity is because you didn't update your ECU definitions, which are released independently of the software (see the faq in this forum). |

No, disabling the DTCs does nothing in relation to the readiness tests. That is, it does not hurt, it does not help, whether they are disabled or enabled. The only thing that impacts the readiness tests are the cat efficiency fixes (whose description was incorrect under previous ECU defs) under the emissions tab and also the force readiness fix.

Update: I flashed my ecu with the A4SGE01C map with the TGV Fixes and all the TGV DTCs disabled and after driving ~100 miles all the readiness tests were complete and no codes showed up.

I've passed emissions with deleted TGV codes using enginuity (which is obviously now romraider), and I live in CA
EDIT: holy crap, I did not realize how old this thread was |

'I've passed emissions with deleted TGV codes using enginuity (which is obviously now romraider), and I live in CA'
do you mean deleted DTC codes? how do you delete TGV codes? do you mean disable the TGV CEL fix? few incorrect keywords can leave us all guessing what you mean thank you |
