I am looking for an Ethanol Content kit for my 2020 X3M Comp. I have the BM3 tuning platform right now tuned Stg 1 E30. I want to either know the Ethanol % i am running or maybe even turn on the FLEX fuel tune in the Custom Rom settings and run E50.

The kits I see available are:

1. Fuel It S58 X3M Kit
2 MHD CAN Bus S58 Kit plug n play (Ecutek only)
3. Visconti S58 X3M CAN Bus kit
4 BM3 Flex Fuel Kit CAN connection (in the works)

How many people have used any of them besides the "Fuel It" kit.

The other CAN bus options will self correct for ethanol with Flex Fuel enabled. You can use the "Fuel-It" kit to find the ratio by hand and do a live adjust on the Ethanol content when you fill up.

The Fuel It kit is almost $500 when you add tax and shipping
The MHD kit is a great looking kit, and is very affordable but wont work BM3 (No PTCAN2 support from BM3) $490
Visconti Kit dont know what it looks like but $700 after shipping and tax.
No price on the BM3 kit as its not been released for the X3M yet.

Anybody got any thought/opinions/experiences on any of these options?

Is the manual adjustment just as good?

Has anybody gotten any better pricing that what I have found.

TIA

I have a Bend Calibration kit I’m testing out for them right now on my X3M. I’m currently running BM3 and it’s working great. Also to comment on the BM3 manual E% adjustment; that needs to be done everytime you start the car and mine had some weird intermittent issue with logging when doing that. This was early on when I was connecting to the Bend ECA via bluetooth to read the content before I had the wires tapped into the PT-CAN. I definitely hated doing the manual adjuster and do not recommend.

It has a fuel filter/flex sensor under the driver side, super easy to install the filter and flex sensor with two nuts to hold the filter down. The Analyzer wiring is very easy.
I know they’re working on a couple things to help optimize so I’ll wait to post pics until their official release but feel free to send ian@bendcalibration.com a message to ask about it; maybe they need other testers.

I’ve ran their flex/filter kit on my M2C for 4years now and it’s been great.

Thanks for the update and advice. I'll pass on the fuel it kit then. I like the MHD kit alot but it won't read on BM3 due to running on PTCAN2. BM3 isn't set up for PTCAN2 from what I was told. I've emailed Ian I'll see what he has to say.

I'm guessing on the E30 content. My LTFT is about 1.04 so I'm thinking I'm pretty close on �� content to E30.

Looks like the BM3 S58 flex fuel kit is available now. Anyone tried it yet?

I tried it and little disappointed on power output on the ots multi map , took 3hrs for me to install. Theres no room for the sensor without bending and cutting off the stock fuel line which took most of the install time . Plug and play a little bit different than the g80 install video.

Ran a 11.3 at 122 and a 11.4 with e60 and e70 and a little 93 in tank

IMHO when it comes to OTS tunes it's hard to be disappointed because you're getting a fairly mild tune to account for the differences present in every vehicle they're flashed on.

Bang-for-buck it's gonna be custom tune every singe time, atleast for me.

Yeah, something isn't right...OTS 93 should be able to easily cut that time

Try to get a custom flex tune. OTS tunes aren't the best for optimal power.

Any new updates since more time and more options?

I don’t remember sorry I sold the vehicle a while back. I followed the g80 bootmod3 install video on YouTube from bm3 as my only manual. I remember some connector areas were different from YouTube

They have two version for the F97/98; the OEM fuel hat or engine bay location. Which of them did you get? I am guessing the engine bay location?

If id want to run e30 would i need to upgrade anything ?

Friend of mine is saying id need too upgrade my fuel pump.

In canada so i wouldnt be running ethanol blends often. Just wondering for a few track runs in the coming summer.

I got the oem fuel hat location. Not sure if anything changed with updates. but I was only able to run up to e60 before it started to sputter and go limp mode
