That would be awesome. "Buy Cobb Flex Fuel from us receive Exx tune for free!"
But I seriously love your customer service and products!

What's more user friendly than flex fuel? Cobb Flex Fuel was not available when MAP took up the delicious tuning unit. Which requires their own tunes. |

Bro, there is no more user friendly mod that Flex Fuel. Is literally made to be user friendly, sure it might costs a pretty penny but its pretty much plug and play. They even labeled / color coded the connectors for you. Having only two choices of maps isn't really flexible. Is either one or the other with some leeway because of close loop. But with Flex Fuel you can run anything from E0 --- > E85 and the tune will adjust based on what % of Ethanol is in your tank. The only thing more user friendly is to have the AP grow arms and legs and to the fueling for you. |

I didn't realize I was so naive to FF Tuning
So I could run 93 up to E30 on this theoretical tune and FF kit with absolutely no problem? If so, I'd buy one immediately. Would it only work on stock cars or would it work on modded cars? |

The purpose of the Cobb FF Kit is to tell your ECU what is the content of Ethanol currently passing thru the sensor. With that variable, your Flex Fuel tune will adjust accordingly based on a low / high limit. Here how things went when i did my Flex Fuel tune last week. After you install the kit, you either get it E-tuned or protuned with a FLEX FUEL tune. The AP has special tables for Flex Fuel tuning. The tuner will tune to your lower E limit ( regular gas ), once that is done, you will be asked to add X amount of E85 to make your top limit blend. ( My tuner capped mine on E50, so i added ~8.5 gallons of E85 then filled it up with regular). Then you repeat the tuning process with this blend. Once its done, you will have your low and top limits set. Once you get those delimiters, you can mix match any blend (E10, E17,E22, E41, E69, etc etc ) and the ECU will scale up or down. You don't need to manually change maps You can, of course add as much E85 as you want and go over your cap ( in my case E50 ), but it won't do any good, since the tune is capped at E50 timings / power. Don't want to hijack the thread, so if you got any questions, just shoot me a PM Last edited by dvazriel; 08-11-2017 at 10:57 PM. |

This is awesome info, thank you! So just say there's no e85 stations and you have to put in 91 or whatever octane is there the ECU will accordingly adjust via Cobb FF kit? |

Yes. A google of "What is Flex fuel?" Will fil Lin most of the gaps. There are quite a few write ups of Cobb specific flex fuel also. The info is out there for sure. |

I appreciate all the info here. I wasn't exposed to FF before but I'm interested in an easy solution. Is E30 generally considered safe to run with the stock fuel pump and without any HPFP issues?
I'm interested in getting an e tune for both 93 and E30, that way I can switch between them. |

I've never seen anyone report a problem at E50. So E30 shouldn't be an issue. E70+ for me on the regular. |

With my Flex Fuel I’ve ran E65 blend on a few ranks back to back with no problems. I think the only problems come from running a high content like pure E85 all the time. The consensus seems to be that you always have to mix, but that’s the beauty of Flex Fuel because it auto-adjusts |

OK, way too long of a delay with this, but it's coming! I promise. Just finishing up our E30 tunes for the MK7, and then we can finish the the Rex.

***These are not official****But we have some preliminary testing complete with our shop WRX on E30.
Here is our 93 octane Stage 1 tune, vs our Stage 1 E30 tune: And our Stage 2 93 octane tune vs. our Stage 2 E30 tune: |

Wow these look great! Ethanol definitely seems like the easiest, cheapest way to gain BIG power. Even with the FF kit and an expensive eTune, I still think flex fuel was my biggest bang for the buck. And now there may be an OTS map that allows you to gain some of that power for a fraction of the cost and zero parts/installation? Sounds great to me!
Ian, why are you capping at e30? Is it too dangerous to make an e50 map? I would assume you could create an e50 map, bring down the boost and timing to that of e40, and then a customer could run e40 or higher and still be safe. I've read that most of the gains after e50 are minimal considering the risks of running high e content, so that may be the Goldilocks zone. Just throwing out the idea in case it hasn't been brought up or discussed before. |

In the end, that is certainly the idea. Currently our shop car is on full E85, for the past 10 tanks or so. We are doing some long term testing with that, and determine how far we can safely go for an OTS style tune.

320 on E30 seems quite a bit high. Your dyno does read pretty high in most of the charts I’ve seen which could explain some of it. My car makes 310-320 on a mustang on E60. My tune is fairly aggressive.

Dynjoets don't read "high". They are consistent from state to state. They can be effected by weather, and barometric pressure, but I could make a Mustang dyno read even higher, or much lower.

Ok. I’ll make what I mean more clear. In the 100’s of charts here from all dyno types. Your dyno is near the top of the spectrum when it comes to like cars. |

Really? My stock WRX base line is one of the lower readings I have ever seen on the forum.
Again, not sure how you can even fudge numbers on a Dynojet. Not sure what else you want... And who cares about numbers anyways? What I am showing is the percentage gained between tunes. |
