What input are you monitoring to get your E%?

There should be no reason my car is running so rich. I have called them and I was immediately told to send in logs, and the answer I received in an email back was unacceptable. I sent another email as I am too busy to call right now, hopefully I can get some real answers. |

They made for 422WHP with just a DCI. Inline pump is recommended for 60%+ mixtures. Flex fuel kit is to measure ethanol content, and the tune will compensate accordingly. One of the issues with E85 use in its current usage is getting ethanol content consistent, so the flex fuel will compensate accordingly if you have end up running less ethanol content or more. Nothing here is needed, it is just for the quest in the most efficient gain in power and consistency. There is a plethora of information and it's easier to read on their site: http://procedetuning.com/BMW/n54/styled-19/index.html

Biasing works both ways. Set the cells, say, 60 across and see if your AFR bumps up ~0.8 across the board. Not sure if the DME limits for rich/lean conditions are different before intervention, but its worth a try. I would NOT set it any more than 10 points either way in the bias map, but worth a try. If it does enlean the AFRs by ~0.8ish after a couple pulls, then its definately your flash likely being set up for gas. Althoguh IMO it sounds like it already, but if you want to put a nail in the coffin.
Edit: before doing any of the above, post of log with fuel correction so we can see that the procede is actually applying no bias at all. I'll never reccomend intentionally going lean (0.8 above 11 is acceptable) but for any other people who find this post and think its acceptable, its generally not. |

I checked the correction and I am pretty sure it was flat with no correction. I will double check again before any new changes. Last edited by BigBoosting; 12-04-2012 at 04:07 PM. |

I'm wondering if it's the firmware you currently running? |

Oh man... Off the top of my head I know it's one of the debug channels. The Flex Fuel sensor is wired to the Procede.

I am using the 111 firmware for the 50/50 E85 maps. Is it possible I should be running the flex fuel firmware and maps, even though I don't have the flex fuel kit?

Ok. I went out and did multiple 3rd gear pulls with the AFR target map set to 55 and 60 across all cells. As you can see in these two logs my AFR's came up each time. So this leads me to believe I have the wrong flash.
Tell me what you all think........ The first log is with the AFR target cells at 55....AFR's came up to high 11's from mid to low 11's The second log is with the target cells set to all 60's. The AFR's came up to low 12's as you can see. |

I can raise the AFR target cells for sure, but to get to high 12's or low 13's I am guessing my target cells would almost be in the 80's. That seem rather high considering the flash is suppose to be ran at 50 and get you the correct AFR's
Also, if for whatever reason I don't have the E85 flash I assume I don't have the timing advance adjustments either to take full advantage of running E85. |

Yep, wrong flash. Technically you can modify the tables so the procede will rich bias the engine and give you leaner AFRs, and with the flash you have, can still retain the ability to dump fuel at will if you go back to gas maps. Additionally, you *can* advance timing in the ignition correction tables, but without knowing exactly which tables are modified during vishnus flashing process, i'd highly reccomend against it at this point.
I've requested publicly which tables are modified for the vishnu flash so customers can know exactly whats been done to their DME. I really think it's still a trial and error process for them, regardless of whats being said. This is not like when my meth kit came in peices or my rev2 came with incorrect firmware, this is frankly embarassing. |

I would agree. It's bad enough to have to ship your DME. Each customer should be getting a full set of instructions on how to adjust the maps after the flash. They should also get some eay way to confirm what is on their DME is the right flash.
We still need that home flashing solution from Vishnu, so we can DL and install the right map without all the hassle. |

I sent them those two last logs. I asked about getting the wrong flash by mistake, we will see what they say. But, In a previous reply to other logs I sent in. I was told that Shiv went over my logs and said they were PERFECT. That an AFR of 11.4 with E85 is I guess "perfect". It makes no sense that I should be running richer AFR's than there pump gas maps, and somehow they are trying to justify that to me. |

On my last DD map, I ran 11.8 AFRs on pump. 11.4 on E is too rich IMO, but such is my preference.
Also, drop the P value of your WG PID settings to get rid of your boost oscillations. |

I am a stickler for details, if its not right, its not correct. Also, I re-uploaded the stg3 map. At an OL of 60, AFR target map cells at 60. I am back down to high 11's, never touching the 12's and my trims actually touched 34%. Something is definitely up. |

With the stories about these flashing nightmares such as what the OP is having I wouldnt think about mailing my DME...Hope Vishnu can create a much smoother process which will benefit both them and the end user..
