If you have a 10th Gen Civic 1.5T and an E85 station nearby, you definitely need to consider this new Flex Fuel Kit by SiriMoto! E85 has become incredibly popular with enthusiasts due to its awesome performance characteristics, cheap price, and availability.

Combined with a Hondata FlashPro, this simple to use SiriMoto Flex Fuel Kit will boost your Civic by 64+ hp and 64+ lb-ft of torque! No custom e-tune or dyno tune necessary. Simple to just install and get going! Free basemaps included for all models, including CVT transmissions (if you have a CVT transmission torque gains will be limited to ensure transmission reliability).

Forum discounts are available for this kit and a combo package with a FlashPro! PM me for details.

Benefits
  • When combined with a Hondata FlashPro, this kit allows you to run E85, which is an ethanol based biofuel and gives huge power and torque gains. E85 also allows your turbo to spool earlier and faster, and causes your engine and turbo to operate considerably cooler and smoother.
  • Not only does this kit allow you to run E85, but it constantly monitors how much E85 is in your fuel, which allows your FlashPro to dynamically adjust your tune so you're always running at peak performance for the given amount of E85 you filled up with.
  • Gains of 64+ hp and 64+ lb-ft of torque! This means if you have a 10th Gen Civic Si, you will be at around 270 hp as measured at the flywheel. Power results will vary depending on how much E85 you fill up with and whether you use a Hondata provided basemap or a custom tune. The Hondata basemap will typically raise boost by about +6 PSI, but it does depend on the exact basemap you load. With other bolt on modifications, a custom tune, and a upgraded clutch, we have seen 10th Civic Si's easily put out over 300 hp! If you have a CVT transmission, torque gains will be limited to ensure transmission reliability.

Why this SiriMoto E85 Flex Fuel Kit?
  • Combined with the Hondata FlashPro, this is by far the best bang for your buck power adder out there.
  • No need to fill up with 100% E85 to get great power gains. E30 to E40 works very well. To make things easy, this kit includes an Innovate E85 digital gauge so you always know what percentage of ethanol you're running! For example, if the gauge reads 37.5, that means you have 37.5% ethanol (or E37.5) in your tank. 85% ethanol would be E85. The gauge also displays your fuel temperature as a colored ring around the main display.
  • This kit was thoroughly tested and designed with very reliable components.
  • Fairly easy to install and flex fuel sensor comes professionally pre-installed on the fuel lines. Comes with installation instructions too.
  • Covered by a 1 Year Limited Warranty.

Key Features
  • Includes everything you need for a complete installation.
  • Weatherproof terminals and connections.
  • Tefzel wiring, nylon sleeved for added protection.
  • High quality Deutsch connector.
  • Sensor assembly can very easily be rotated to accommodate other nearby modifications, like an oil catch can.

More Details / FAQ
Q: What is E85 and why does it easily give so much more power on this 10th Gen Civic turbo?
A: E85 is a biofuel composed of up to 85% ethanol. The remaining 15% of the fuel is traditional gasoline. Keep in mind the ethanol percentage can be lower during the winter months in some areas. The ethanol often is made from corn and is the same type of alcohol you would find in hard liquor, with the exception that fuel ethanol is denatured with additives to make it undesirable and harmful to drink.

The main reason E85 allows for some much more power than traditional gasoline is that it has a very high octane rating, usually from around 100 to 105 octane, compared to 91 to 93 octane from normal gasoline. This high octane rating allows E85 to resist engine knock. Engine knock occurs when areas of the air fuel mixture ignite before the should due to excessive heat for the fuel type used. This is bad because it can cause extra stress on the engine, and doesn't make optimal power either. From the factory, this 10th Gen Civic 1.5L turbo engine is "knock limited", which means it cannot achieve its maximum design power on normal gasoline due to engine knock occurring. E85 basically eliminates this constraint, allowing this 1.5L turbo engine to achieve the maximum power possible for any given boost level.

The only real drawback of E85 is that it will reduce your fuel economy because you need more of it per unit air. One nice side effect of that is that extra E85 fuel will help cool your combustion chamber and turbo, and thus help maintain maximum power and reliability.

Q: Why a Flex Fuel kit?
A: The "Flex Fuel" part of this kit refers to the ability to run any amount of ethanol you want, from 0% to 100%, so you never have to re-tune or worry about how much E85 you filled up with. In general, the more you fill up with, the more power you get. However, if you choose not to use a Hondata basemap and instead get an aggressive custom tune, you will find that the power gains do taper off after about 40% ethanol. In that case, E30 to E40 could potentially give you the best combination of power and fuel economy. With the Hondata basemap, power will continue to increase until about E80. In either case, just use the ethanol gauge we include to see what % ethanol you're running after any given fill up.

Q: Ok, so what do I need to buy?
A: Amazingly, all you need is this SiriMoto Flex Fuel Kit and a red (race) Hondata FlashPro, along with some E85. This flex fuel kit constantly monitors how much ethanol is in your fuel, displays it for your information on the digital gauge, and then tells the FlashPro. The Hondata FlashPro dynamically recalibrates your ECU to give the optimal power gains on any percentage of ethanol you happen to have in your tank.

Q: Is a custom tune necessary?
A: No, it is not. To get the advertised gains, all you need to do is install this kit, reflash your ECU with the appropriate E85 Hondata FlashPro basemap, and fill up with E85. If you have a CVT transmission, torque gains will be limited to ensure transmission reliability. If you have a manual transmission and want even more power, a custom tune (higher boost and more aggressive timing) combined with other bolt-on parts can easily push you past 300 hp. Keep in mind that the Hondata FlashPro basemaps are deliberately conservative, designed with maximum reliability in mind, so they will require about 80% ethanol before giving the most power. If you get an aggressive custom tune, you will find that you will not see much power gains going over 40% or so ethanol in your tank. However, as mentioned, a Hondata basemap will offer better reliability as it is conservative enough to account for sensor inaccuracy and uses more E85 for any given power level, so your engine and turbo will operate cooler.

Q: Where can I get E85?
A: The easiest way is to look for E85 stations using websites such as getbiofuel.com or e85prices.com. There are many stations available throughout the United States.

Installation Info: The product requires a red Hondata FlashPro, which is the race version. It will not work with the blue CARB Exempt FlashPro. You will also need access to an E85 station, which you can find with websites such as getbiofuel.com or e85prices.com.

I forgot to mention that Hondata also recently added in E85 cold cranking fuel enrichment as a new feature on the basemaps. So, basically, you shouldn't have any issues with starting your car. Normally on high concentrations of E85 the engine can take a little longer to fire up.
