Moto west flex fuel kit and OFT

[amartinez9881@gmail.com]

I guys so I'm going to order the Moto west flex fuel sytem and flash tablet but I don't know what I need to do to set every thing up, I know the flex kit is easy install but once I get my OFT what do I do? I know I have to save my stock tune on it and I have to tune for e85. But do I just dowload a tune online for the e85? Do I go to a tuner and get a tune map and have it loaded to my OFT? I need help plz

You'd need the flex fuel bin and slt from Shiv. He doesn't have them available for download. You'd have to email him to get them.

You can just use the OFT E85 bin and load it once your e85 content shows above 60% on your content analyzer or you notice ltft go above 12-15%, but that kind of defeats the purpose of having a flex fuel kit.

Hi thanks so much for info so few more questions who is shiv what is bin and slt and so what then what's the perpous of flex fuel kit if the OFT will do the same? So will that tune give me same WHP gains if I had flex fuel kit

Shiv is the owner and tuner for the OFT. A bin is the tune file. The slt is the file that oft uses as a definition to know what addresses to use for what tables in the tune file. A flex fuel kit gives an input to the ECU to let it know what percentage of ethanol the car is currently ingesting. With a flex fuel tune, it will automatically adjust the tune to accommodate whatever percentage of ethanol the fuel has.

What this does is allows you to fill up with either 91 or higher or E85 at any time no matter how much fuel you have in the car.

The flex fuel tune from Shiv is due to the open source work that Ztan did. In fact all of the non-Ecutek tunes for flex fuel are thanks to that work and the work of Wayno and Shiv converting Ztan's A01G bin over to other bin types.

Prior to the flex fuel work that Ztan did, Shiv had already developed E85 specific tunes that were really downtuned a bit to allow for differences in pump E85 ethanol content. In order to use E85 without the flex fuel kit and tune, you need to basically run all of the fuel down to almost empty, then fill up with E85 and then flash the tune for E85 once the long term fuel trims (LTFT) shows that it's having to add a substantial amount of fuel to maintain proper fueling. This lets you know that the fuel actually going into the engine is of high enough ethanol content to allow for the advanced timing and additional power that the e85 tune gives.

If you need to switch back to 91 or 93 fuel, then you need to run the car back down and put those fuels back in and flash it back to standard.

If you run an E85 tune on standard pump gas you risk seriously damaging your engine. This is one reason why flex fuel is much better. You can pretty much flash and forget. Put 91 when you want and put E85 when you want.

It's still beneficial to have a flex fuel kit so long as it has a readout telling you the ethanol content, this is MUCH easier to monitor and know when it's ok to flash to an E85 tune than monitoring ltft.

This is especially true if you're using tactrix to flash rather than OFT. The only method of actively monitoring ltft with Tactrix is either using EcuEdit or Installing a cracked version of toyota's techstream software, which is findable with a search on this site.

That is the good thing about using tactrix, you can do some extra things with techstream that you can't with other tuning options(at least that I'm aware of) For instance, I have disabled my DRLs (daytime running lights) and the seatbelt not connected beeping.

Based on your level of knowledge I would strongly suggest you go with OFT or Ecutek. You can easily brick your ECU if you don't know exactly what you're doing with the tactrix.

Wayno does some custom tunes for the OFT if you go with OFT. He'll provide you with everything you need once you have the flex fuel kit installed. Just make sure that the input from the flex fuel kit goes to the evap sensor input like steve99 says below...

Most flex kits can work with oft tune, you just need to be able to connect flex sensor input to ecu EVAP connection not the rear 02, oft tune expect flex sensor input on evap only

Thank you so when I purchase my kit I need to make sure I buy it with the EVAP connection , should or do I need to upgrade my fuel pump or my inectors? What are the benefits ?

So just so I'm clear with the flex kit and the OFT I would just flash to the e85 tune and put in the gas either 91 or e85 and not worry about any issues ? But obviously I'd have better whp gain on a full tank of e85 than half a tank of e85 and 91? If I just run 91 do I have to flash over to a stock tune or could I keep it at the e85 tune

If you have a flex fuel kit AND flex fuel tune, you could have half a tank of e85 and half of 91 and the tune will auto interpolate the values and you would have ~half the power gains of E85.

Sounds like OP needs to read up on what a FF kit is and how it works.

You don't need a FF kit to run E85, but there's no point in having a FF kit without a FF tune. Money down the drain.

Based on your responses you haven't done nearly as much research on tunes and this car as you should. You seem kind of clueless, which is dangerous because you seem eager to drop money on something asap. You didn't even type "moto east" properly, and didn't know the file designations of .bin or slt. or know that shiv pathak is the tuner in charge of OFT.


I'll try and simplify this for you:
1) you don't need other injectors or fuel pump, no one on here has said that unless they go supercharged or other crazy power adders
2)If you run it like I do, I do not have flex fuel kit or any sort of sensor which means I have shivs OFT e85 tune and must run complete e85, and have to worry about switching maps and running full tanks of e85 no mixing or my IAMs will get dangerous.
3) Flex fuel kits like Moto-east or the Openflash one, mean no switching and basically no worrying about ethanol content the tune automatically adapts to the flex fuel content in the tank because of a sensor connected to the fuel line as well as a specific tune from ecutek or openflash.


For moto east's kit you'll have to get a tune and there kit which uses ecutek so your ecu will be "locked" after the tune is applied:

http://www.moto-east.com/store/subar...figurator.html

(choosing the enable via cpc option)

For Openflash you need the tablet and the flex fuel kit:

http://www.openflashtablet.com/shop/...flex-fuel-kit/
http://www.openflashtablet.com/shop/oft-frs-brz-gt86/

A FLEX FUEL KIT WILL NOT WORK WITHOUT A FLEX FUEL TUNE

You're lack of research will kill your car, so either call or email moto-east or openflash to get some assistance, both have different price points so bear that in mind
