Simple Civic E85 Conversion! Thanks to Hondata S300 V3 ECU! 

Thanks man!

That's awesome! Thanks man!

Thanks! Hope it helps!

Ayyyyy! I haven't wired up my wideband for closed loop yet, before I just ran it on open loop! But I think I'll be switching to closed! Prolly make a video on it!

@@kraftingkars Yea I'd like to see that video....I didn't realize you could wire it in open or closed loop???? Cant wait for next video

@@theedge5584 so when your running in open loop, you don't have to wire your wideband to your ecu! I actually decided to to keep my car on open loop after talking to some local tuners about it. Reason being is that when you are running closed loop your ecu adjusts your fuel live to keep it at 14.7 afr. Which is fine for n/a cars. But for high HP turbo cars you want your afr around 12:1 when doing fat pulls!

@@kraftingkars Ahh i see thanks for the info. Very appreciated

Yessir! Left to right it is VCC(power), Ground, and signal. To get the most accurate readings it is recommended to use the main 12v wire for the ecu

There shouldn't be any fuel tank corrosion issues, ethanol will damage rubber over time, but won't harm steel.

So it gets kinda confusing thinking about target air fuel ratios with e85 and regular fuel. The stoichiometric ratio is different for each. But the target Lamda will be the same, Which is Lamda 1. Since most AFR gauges and ECU's read in lambda and then convert that number to Air fuel ratio. Your targets in your map and on your gauge are gonna be the same. So 14.7 at idle ~10-11 Wide open throttle, 14.5 for cruising.

Did you wire your sensor like mine? And make the same changes to your map?

This page helped me alot getting it all setup, since you are running an s300 V2 that doesn't have a digital input option. You need to run an ethanol content sensor as well as analyzer, this takes your frequency signal from your sensor and converts it to the 1-5v analog signal that your s300 V2 can read.

It's a great idea to run e85 in that car! It will be much safer!

The short braided lines from the stock lines to the 3 port fpr.

At first yes, but now I'm running -an lines all the way from the pump to the fpr, you can see make the conversion here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LMrDm6dCVmQ.html

Just the factory grommet, I opened it up a little bit to fit all the new wires

Yes I would definitely recommend that! Most aftermarket/performance pumps and injectors are built to be e85 safe. I believe they use a different kind of rubber seal that holds up better to e85

Yep, you want to have each of those components be e85 safe. I'm running walbro 450 fuel pump, deatchworks 1000cc injectors, ptfe fuel line, etc

When i watched you build the hoses, pretty sure they're AN, not PTFE

Good question! I believe everything is explained best on the hondata site. Here is a link to the guide I followed, my setup is working great! www.hondata.com/help/smanager/index.html?flex_fuel.htm

​@@kraftingkarsI noticed in the video that there wasn't a 2.4k ohm resistor wired between the Out and Vcc as mentioned in the guide. I was wondering if this step is necessary?

​@JeminoWayde the manual says to run a 2.4k resistor btwn vcc(+) and out(white wire).

If you're running e85 only, then no.

Most e85 pumps in my area don't have exactly 85% Ethanol fuel, which is where the sensor comes in handy!

Nope! As long as your senser is in line with your fuel return you are good! A nice 3 port fpr with an fittings helps with keeping things simple and reliable!

Nope not necessary, now that's is flex fuel you can run any fuel you want

Benefits of flex fuel is you can fill up at any gas station with any fuel that you like besides diesel. Putting e85 in a car without a ethanol content sensor is ok if the car is tuned on exactly e85, but the gas stations around me are not consistent enough for that, best I get is E65 around my house

Thanks for the advice I received the tucked harness I lurned a lot , now let's get some fun, appreciated
