The verbiage on their site is confusing. I think it's 349 Euro if you order and ship within the European Union. If you order outside the EU, it's 281.45 Euro because you don't need to pay 24% VAT (Value Added Tax).
That's how I interpreted it. From their ordering page: "1-8 cylinders 349 € (281,45 VAT 0 %) Prices are without taxes (24 % VAT) when ordering outside of EU or EEC." |

So is this kit compatible with the s65 motor? If eflexfuel kit does the same thing as the AFD kit I rather get the eflexfuel one because its cheaper. I've sent out an e-mail to eflexfuel to confirm whether or not this kit is compatible with our cars. Anyone have this kit on their car running e85?

This is all slightly confusing because if you check the compatibility of the eflex kit on their site it says that it is not compatible with the 2007-2013 4.0 m3? Im very tempted to order it and just give it a shot. I work for a performance shop and have access to a dyno. but most cars we run e85 on require quite a bit of tuning even if NA.

I've been scared to pull the trigger on this for a while but that one guy with the C63 benz loves his kit so lets roll the dice. Thanks! |

Do let us know how it goes, so I'll kick myself for not buying it now with the coupon. |

This is what I was told by eflexfuel. Might go ahead and buy the kit eventually. Seems like to me there is no real difference between AFD and this kit besides the software.

Once I get mine in we'll see how it goes. I've had the car dyno'ed at a shop with the current mods minus the flex fuel kit so even though it won't be on the same day it will be on the same dyno. I'll try and buy a 5gal jug of VP e-85 to get the best results. |

So far so good for me. Got about 5k miles on it and no issues. I just dyno'd on 65% yesterday and found out it's good for about 20 rwhp for most of the powerband but it got real rich after 6k rpm. Ended up with no gains from 6200 on vs 93. Even at 3000 rpm it runs about .7 richer than on 93. So in my case a retune is necessary....but given how much fuel can be taken out I think there's a lot of power potential once properly setup. Anyone who purchases one of these kits, rather it's the cheap one or the afd, should consider getting on a dyno asap to see what's going on with the a/f.

BTW, I don't think you can compare AFR readings of gasoline and e85/e85 mix. Your target AFR is different for gasoline and e85, so taking out fuel at high rpms might not be the right thing to do. Last edited by JsL; 06-14-2018 at 10:59 PM.. |

Don't quote me on this, but I think I read somewhere on here that AFRs for e85 vs 93oct. will be different. Somewhere along the lines where what is considered acceptable AFR range for 93 is different for e85. Perhaps running richer on e85 is necessary for that fuel because e85 consumes more fuel then 93? I don't know if I'm making sense. Any input would be appreciated! I do agree that a proper e85 tune would yield far better results then flex fuel.

To run E85, you need to add about 30% mass flow to maintain stoich. Since the O2 sensors are read out as lambda in the DME, the DME always maintains lambda to the target. There is a parameter in the DME for stoich value that isn't changed with any of these kits. What these kits do I suspect is intercept the pulse for the injector and add pulse length to account for the necessary added fuel mass and that percentage increase is based on the value of ethanol per the sensor.
None of the kits I've looked at have any interface to the coils though or any feedback line to the DME that would affect timing. (If they did, the ionic current system would probably throw a fit). The statement was made earlier in this thread that the AFD kit would pull timing up high, but I'm trying to understand by what mechanism that would occur in the DME with the AFD kit vs a stock fuel system. I would suspect if you logged fuel rail pressure on the AFD kit you might see some difficulty with the stock pumps hitting the pressure targets and the DME is pulling timing preventively, but I'd have to go back and look at the mapping to confirm that. As for the power increase with E85, unless timing is advanced by separate tuning of the DME, all the power gains come from the increased charge cooling as a function of the higher latent heat of vaporization as well as the increased mass flow injected. AFD seems to have based their marketing on that whereas the other company has not. Even without retuning for increased timing, gains are to be had. The problem with increasing the timing is you better know very well what your ethanol content is because the DME doesn't and can only correct by pulling timing if it does sense knock. Also better make sure your tuner isn't one in favor of disabling knock sensing in the mss60. |

I m in europe and could go for it if you give me a good contact for the tune and not one that will charge too much for it, don t want to pay 400 for the kit and 1500 for the tune
