Pump gas fuel trim increase 50/50 E85, no flex fuel sensor E85 flex fuel Single Turbo I think what you are referring to is accomplished by changing all the AFR target cells to 50. I called and they had me email them in a log, so I guess we will see if I get an answer. |

With E85 you can run a point lean without issues due to the cooling Ethanol provides with direct injection. You also pick up torque because if I'm not mistaken, peak torque will happen at 13.5:1. In map 3 for Flex Fuel, the PROcede implements enleanment to overcome rich AFRs with e85. It allows you to keep the same fueling table if you switch to pump and meth. Without enleanment it will allow you to hit 12.5:1 while in map 2 and 4.
If you run e85 with meth like I do, you'll need to log to make sure you don't run too rich with e85 and meth and make adjustments to accommodate the AFR targets you want to hit. BTW, 13.75 was without meth and my AFR tables are set to run with meth. |

Is there a simple step I am missing when changing the AFR table values? I changed each cell one by one to 50, then reset the Procede, turned the car off, waited a few seconds, and then started the car back up. OL is set at 60 with trims hovering around 24%.
I then did a few logs and the AFR's are identical to what I was seeing before I touched the AFR target table. |

Before the flash, I was maxing my trims of course but my AFR's were fine. 14's around 4500rpm and tapering down to mid 12's at 7K. This tells me there is something else going on after the flash. |

Uploaded the stg1 E85 50/50 map to see if it made any difference. It did not, same 11.4 AFR's across the board, even with the AFR target map cells set to 50 and OL to 60.
I called Vishnu and was told to send in some logs. I did so, and there reply was that mid 11's is a great AFR.............NOT FOR E85 it isnt!!!!!!!!!!!!!!!! WTF, no help |

Don't feel bad, mine are in the mid to low 11s also and there is no doubt it's directly related to my flash also.
Before flash was in the mid to low 12s at higher rpms, day I put it back in it was down to the 11s. I wish vishnu would address this more with a detailed write-up instead of just saying to change afr targets to 50 across the boards which has done nothing. This flash has helped my fuel trims but has caused me to lose a decent amount of hp/tq with these low afrs, especially when running e85. |

I want answers. I didn't ship me DME across the country and pay for my car to run worse 2 weeks later.
I don't think that is an unreasonable opinion. I sent in more logs, but from the first response I got saying the AFR's are normal doesn't leave me with much confidence. Either that person doesn't really know whats going on or they didn't listen at all what I asked. |

Thought I would drop a log out here. Although I'm setup to run meth with e85, I didn't running meth on this run. I'm in flex Map3 with enleanment enabled. So that's why I'm hitting 13.5 to 14 AFRs. I'm sure that would drop a bit in Map 4 with meth. My boost target is also 2 psi lower without meth. I included fuel pressure because I'm running the new booster pump if anyone was interested. Prior to putting the booster pump, I was getting low pressure codes running 60% or higher Ethanol content.
At the time of this run, Ethanol % was at 81.2% according to my Flex Fuel sensor. |

My AFRs are low also running the flex fuel kit. Right around 11.0 plus or minus a tiny bit. |

That log is from 4000 RPM to Redline
It's 18 PSI tapering to Mid 12's at redline, which is a little low on the top end but otherwise pretty normal for a car not on methanol. Where it is low on boost it makes up for it with high ignition timing, which is about 15 degrees on average, 3-5 more on average then your typical pump gas car. One could push a methanol car to about 15 PSI at red line if they wanted to but that's a story for a different day. |
