Will the is350 run well with a blend of e85?
Based off the below thread in the ISF forum, which seems to be getting quite some hype, what are you guys thoughts on how our model 3is(350) will fare blending e85?

Wish I could pull KCLV with the torque app - what's the cheapest way to get this data?

Based on the one guy that did before and after dynos, the gain are very nominal - seems to be more "butt dyno" than anything. Additionally, the imprecise method of measuring the exact E85/gas blend (without a dedicated ethanol meter), and the fact that you need about 20-25% more E85 than gas, all things being equal, seems like a lot of risk to run without bigger injectors and a proper tune for minimal gains. Just my 2 cents.

I wouldn't recommend more than a gallon or two of e85 per tank. yes it will raise the octane, but if you add too much it'll throw off the fuel trims too much and the car won't run as well.

This is correct. OP you MUST adjust/tune the timing/ECU/fuel system to keep the engine running smoothly. The fuel pumps/injectors in our cars can't supply the amount of e85 required to run smoothly. There's a reason there are FlexFuel labeled cars.

No flex fuel sensor, improper lines and gaskets, wrong injectors, wrong timing on the ECU, ethanol attracts water like crazy, etc. but yes please do put e85 in your car and report back in 6 months how it worked out for you. You know that diesel last long and is more stable than gasoline, maybe you should try to blend that too for longevity.
Being a ******** aside. Do not do that, it’s bad for your car.

How long has the ISF thread been active?
Might want to do your diligence before you hypothesize.

With my supercharger my car is tuned to run an e30 mix and the gains are very good over running just 93 some parts of the dyno graph I gain almost 50whp with the mix versus 93.

Unless you can tune for it and have a real time Etanol meter it’s not worth it. Ethanol will raise your octane rating but unless you compensate by tuning for additional timing your not doing much of anything good, you will however start to degrade your fuel pump and fuel line and this can lead to failure over time. Plenty of force induction guys use this and we know for a fact you will mess up non E-85 fuel pump and lines, you will also see no real gains unless the ecu and adjust timing for the additional octane.
i don’t know about our fuel lines but the rubber o-rings and connectors are subject to fail if the underbody lines are steel.
Simple question. Do you think adding in 115 octane race gas will do anything to your stock car? No, it won’t.

With out additional tuning to your ignition and fuel maps you will not see any gains pass what the max ignition and fuel tables has to offer on your stock ecu.
You will for sure run less knock on the knock sensor which will allow the ecu to push the ignition table until it max out on what it can do and that is as far as you will get.

This is highly documented in the ISF thread with significant gains and very little issues.

Exactly so if your only running 91 and mix e30, this will bump timing as long as there is no knock . Also you'll slightly lean out and make more power and it's safe to do so because of the higher octane an e30 Kishore will consist of.
