5sfe performance mods Options

I have a piggy back ECU installed that makes my Celica "flexfuel". It runs way better on E85 than pump gas.

This mod is great because it increases performance and saves me a bunch of money on fuel. E85 ethanol pumps are going up everywhere, and if you have one near you, I would consider this upgrade a necessity.

E85 is 105 octane. Thats why it will increase performance, even on a 5sfe with no mods. The owners manual "recommends" 91 octane so you know that higher octane is going to increase performance. The easiest way to increase performance is to increase fuel quality, and this mod will save you money at the same time.

Actually, the "box" has a dial that lets you adjust the trim if you want to. I'm running a much leaner setting then I could. I don't really care about the extra power I could get. I don't have anywhere to get in that much of a hurry and the roads in my area are all super slow.

Ethanol is a really good solvent so it actually cleans out carbon deposits. It runs very smoothly. I can shift to a higher gear earlier. Theres lots of benefits.

Ethanol does run better, especially in the mountains. It is 34% oxygen by weight. Less oxygen has to be pulled into the manifold. It burns colder too, not as much energy is lost to heat.
