Hondata Flex Fuel upgrade - 265 hp and 285 lb-ft on a stock Si

[Hondata]

Available Monday Hondata will release the Civic FlexFuel upgrade for the Civic Si.

Using inexpensive ethanol sensors and high ethanol content fuel it is now possible to make significant performance improvements with the supplied calibrations. Not only will your Civic make more torque and power, but it will spool the turbo earlier and faster while operating considerably cooler and smoother.

Unlike manufacturer flex fuel systems, the Hondata Flex Fuel upgrade dynamically adjusts the tuning for peak performance dependent on the ethanol content of the fuel. Just plug in, fill up and go. Gains of 64 hp and 64 lb ft torque over stock are possible for a total of 265 hp and 285 lb-ft torque.

No tuning required. Just plug in, fill up and go.

Here's a quick how to:

Very nice, I love the guide to “build your own” setup. Very economical compared to other options.

Very economical.
Can be done for $250 with dorman fittings or $325-350 with AN lines. This is all retail price and not wholesale

@Hondata would this work on all 1.5 civics or is this only for the Si? I’m assuming if it was to work on the non Si models the hp/tq would be less.

It will work with all 1.5t but Si will get the update first.

I recommend a 1ft russell fuel line and a 2ft Russell fuel line

For the base Civics the peak torque should be similar but peak power will probably be down a little. The following software update will cover the other Civics. For those with an upgraded clutch, there's probably even more power and torque to be found.

Do you have a MT? If so install a flex fuel kit, drop me a PM, come visit our dyno and I will do a couple of runs for you.

I do have a MT. Thanks Doug.

The real question is will this mess with our Honda warranty chances? I know there is a dealership that covers Hondata reflashes, hopefully this will be covered, too!

Well as it says, no tuning required. However you are modifying the fuel line. You could buy two, so you can keep the stock one to switch back to when you go to the stealer.

Warranty does not get void unless the part you added was the cause of damage

Here's my setup with AN lines. Idea is to use a 6" fuel line on the firewall but the smallest Russell sell is 1'. You can also make your own line too by buying 3 or so feet of teflon -6an line and 4 -6an fittings.
I have it temporary mounted there. I plan on tucking it somewhere. Where it's not as visible

I went with the zeitronix ECA-2 kit. The kit and AN fuel line costed me under $400 on Amazon. I believe the Innovate kit is around $250. Dorman fittings is $10 or AN for $100 or less

I understand that, but this is a signifiant increase in power with an engine that isn't 100% tested yet. Messing with something like the fuel system would be really easy for Honda to say nope to your warranty.

If you are worried then put the stock line back on. You can get a new one for $25 or run AN lines and keep your stock line
