Ethanol blend
Hi guys,
Just read Shiv's post regarding e85 and how if we are N/A there isn't a necessity for e85 since our dynamic compression when N/A can't take full advantage of full e85, and ideally all we need is e40. So my question is has anyone run e40 on the oft STG 2+ e85 maps? If so what was your experience in terms fuel economy, fuel trims, performance, cold starts etc...? Also if e40 isn't an ideal blend, what blend would you recommend? I have a catless header. The post I'm referring to https://r.tapatalk.com/shareLink/top...ink_source=app Thanks Sent from my SM-G950W using Tapatalk Last edited by yzf219; 11-13-2020 at 05:07 AM. |

Try not to run anything other than e85 on an e85 map. The engine is expecting e85, and will run rich unless the engine fuel trim can cover for it.
A few % off of 85 would probably be just fine, but I don't know enough about the engine to say that it can adjust for e40 If you care about running e40, blend it yourself an get a flex fuel kit. |

Cheers I remember it now.Good e85 is 105ron and runs 14:1 comp safely. 93ron runs 10.5:1 comp safely. Obviously with modern ecu`s you can push safety limits further. The fa20 is 12.5:1 so it would fall in between.
Nothing like having a nice anti knock safety margin with your fuel. For 2hp loss why run crappy fuel. !`m possibly a bit spoiled with our e85 its exxy but always e80+. |

Our Cars love E85. If you can do 1 mod and have reliable e85, Tune+Flex Fuel is all I would do+ Axleback for sound.
