Interesting. Titanium shows your driver as C475_526 with an EDC16C2-9.9X Maybe this ecu was for a different emission regulation? For a simple EGR/FCV delete, we modify five locations. I checked your file and the first three are in exactly the same location as the 808. I would begin here. Learn how to use WinOLS and modify your maps the same way as Yeti's 808 delete. This will give you better fuel economy, more pep and a cleaner ride to start. But as Nick says there are a lot of differences in everything else! |

I'll take a look and try to figure it out, would like to find some more documentation on how to make these changes. Any help is appreciated. Sorry not trying to hijack the CRD tech thread. |

There is a guy who has put in hours on WinOLS howto's at youtube. Find one, go to his youtube home and scroll to the bottom of his vid list with the "Load more" button. Start with his first vid. Sorry, unless someone joins the thread who has done this and owns a 526 version, you are the guy. The good news is Titanium finds a driver for your software so you can modify driver's wish, torque limit, smoke map, boost, etc. And the hidden EGR/FCV delete is in the same location as Yeti-808. |

Has anyone made a stage I tune with the EGR/FCV delete, and delete the MAF with no DTC. Right now if you unplug the MAF with the current EGR/FCV delete tune, you get a CEL. Would like to do away with the air intake box and MAF sensor and replace all the parts with a huge round K&N air filter like I did on my Dodge...Hopefully it would make this baby breath a whole lot better I would think? thoughts? |

Maybe modifying the Smoke Map (if we have one)? Like the EGR, it also uses MAF data. |

I have the GDE tune so they are useless. Based on this post, it must be possible to disable them??? I would like to do this mod, but got to figure out how to get rid of the MAF and temp sensor without a CEL. |

Maybe modifying the Smoke Map (if we have one)? Like the EGR, it also uses MAF data. My understanding is that the smoke map is essential another limiter too prevent to much fuel from being dumped, causing smoke. What I had read is that they need to buffer the optimum AFR by about 1.2x to achieve 0 smoke, so they have to run it lean to prevent any smoke. The smoke table looks at the incoming air and will reduce fueling if necessary to prevent smoke from occurring. The problem I would see with modding the smoke map is that the Jeep may smoke if you were to max out the values, or it may stop all fueling if you zero it. Either way I bet the smoke map still looks for the MAF. If you read through this site(https://sites.google.com/site/vagecumap/edc16-error-dtc-removal), they explain about DTC's and how they are handled in the EDC16. Essential each DTC is given a handle code which tells the computer what to do when the DTC trigger(IE should it just turn on the CEL, should it go to limp mode, should it save the DTC in the computer etc etc). If you zero out this handle code it causes the the ECU to never do anything with the code, it essentially ignores it. I attempted to find where they are located but couldnt, or didnt put in enough time. I also would love to do this since my MAF appears to be dead and I just want the CEL gone! EDIT: Come to think of it, isnt this how Toy-vw was working around his EGR block. It sounded like he had just deleted the codes but never actually turned off the EGR, just blocked it. |

Must be possible if Scott was able to simply unplug both his sensors and tie them out of the way. He stated they were useless with the tune he has? Only other option I see is to figure out how to mount the sensors in a 3" adapter pipe between the turbo inlet pipe and an round type air filter? Really not what I want to do though!!! |

Cable ordered and looking through this thread now! Can't wait to see what results we get from this! Especially the EGV delete! -Grant |

Hey Guys, I've read through this thread and so far great work but I was wondering if it was possible to get some clarification on some things. Here is the list from the first post: Squeeto wrote: Please refrain from contacting members by PM en masse for maps. Use at your own risk: Nick's 808 ECU/FCV delete + (some) HP tune (vers 1.01), link- https://www.dropbox.com/s/cfjaakd7ma4qu ... .01%29.bin Nick's 811 ECU/FCV delete - stock, link- https://www.dropbox.com/s/z7bsfko2gl3rk ... k_Tune.bin Nick's 811 ECU/FCV delete + Stage 1 tune (vers 1.01), link- https://www.dropbox.com/s/jb5lt636epq13 ... .01%29.bin Yeti's 808 ECU/FCV delete - stock, link- https://www.dropbox.com/s/yd02x3mlcb9eg ... k_Tune.bin Yeti's 808 ECU/FCV delete + Mild tune (vers 1.01), link- https://www.dropbox.com/s/w95ou8pxkzo3g ... .01%29.bin Yeti's 812 ECU/FCV delete - stock, link- https://www.dropbox.com/s/rkokvq4jm92vr ... k_Tune.bin This post will be updated as needed. Some are self explanatory, such as the ECU/FCV delete + stock, ok that makes sense, but for the Mild tune and HP tune, can we get a more specific description of whats going on with these tunes? Like what exactly is the Mild Tune? Thanks Grant |

I will be working on my own tunes as well, I want the EGR delete plus an eco tune as well, so that is what I'm looking to focus on personally once I get my cable in. -Grant |

Maybe you never got the F37 and therefore your software version is different. |

Isn't everything hardware wise the same for some reason it just looks like all my software versions are older despite a June mfg. date All the differences with your file are in the areas that we don't usually touch. I checked your torque limit, over boost, rail pressure and turbo pressure in Titanium and it is the same as the stock 808. I recommend the safe route. Take Yeti's 808 delete file and modify your maps the same way for the 5 modifications. If you like that, then move on to his tune file. That way you keep the base system as it should be and gain all the improvements that he has. I am curious to know what the 808 would do though When you get to the egr hysteresis maps, consider changing the zeros to 3600 in the red circles. I believe these are incorrect. Before and after for 3rd and 4th mod: |

Post subject: | Re: DIY ECU Flash |
the map i have touched are: gas pedal and limiter FCV and EGR injection timing Rail pressure and limiter turbo pressure and limiter overboost time ...a little bit engine torque limiter fuel request / air increased and limiter ........smoke MAP torque on A/T for every gear it's not the maximum torque that the CRD can give , but a compromise of fuel gain and power for WWDiesel , the only DTCs delete in you'r map that i have see it's for EGR and FCV , but im not sure , because i have compared with Nick map |

So I can link to this post and assume that your tune is not full torque but does increase fuel economy and power over the stock tune? Probably a good option for those who still have the original torque converter. |

Post subject: | Re: DIY ECU Flash |
yes ........two time , it's a response and yes it's not a full torque , I do not want to create problems in an engine that is problematic in its , as long as I work on mine, I test, but not on the other KJ |
