How involved is the ethanol sensor install? Is it relatively straightforward to install and wire into the CAN bus, or is it involved and require special tools?

Simple wiring, however I always recommend someone who has previous automotive wiring experience...solder monkeys can keep their hands off. Power, ground, Can Hi, Can Lo connections. A good wire stripper and proper crimp tool would be required imo. Bend Calibration has a very in depth installation manual which is provided for clients only. Here's some general wiring stuff:

The easy button:
BMW 2 Pin Adapter: (If it’s good enough for
BMW’s Car Eye Install...should be good for this.)

He's spotty on email responses but his tuning abilities, and feedback from clients is excellent...

Its a 3.5 hr drive but I'm looking fwd to it...

You ever have John tune your car? Apparently I live a quarter mile from his office...

Awesome - thanks Kenton. You do most of your tune revisions and log on the street and just send them to Ian after?

I just threw DPs on the M3 the other day so now the flex fuel is starting to look super attractive...

Lucky you! No I had to cancel. Will be going down in a few weeks. Will post after its done

I did everything remotely and on the street. Dyno before tuning and after tuning to verify gains. I haven't reflashed a new bin file on my car since the car was dynoed and have been putting plenty of miles on it at various flex % with not one hiccup. It's such a great setup and I can't say enough good things. The best part is how smooth it drives even when compared to stock. S+ mode was always jerky and my wife and I can now go into a parking lot and daily drive the car in S+ mode with no angry eyes from her 😅.

Out of curiosity, is there anyway to still utilize the M1 and M2 buttons on the steer wheel to switch maps on the fly? Does this thing have the programming logic to "curate" only compatible maps based on the fuel that is currently being ran on the car?

The M1 and M2 buttons currently work as the OE BMW system does for Efficient/Sport/S+ mode switching.

Map switching works (on the fly) by holding the cruise control button and then using the toggle switch to change the map.

Each map can be customized to run whichever fuel you want. So Map1 could be flex fuel and utilize the flex sensor for blends of E85...Map 2 could ignore the flex sensor and be tuned for 110 Leaded Fuel...Map 3 could be C16...Map4 could be w/e unleaded octane fuel. It's all custom to the users needs.

Let me get this right....so you're saying that the efficient, sport, and sport plus modes as well as s1, s2, and s3 gear settings, and corresponding steering wheel icon handling settings work exactly as if the car is stock? Despite the car running a customized tune file? How does the tuner account for these OE settings across the 100+ maps?

Easily...they are tuners .

They can also customize the throttle in the various modes and control the exhaust flaps. In my car the S+ mode has been tuned to keep throttle more linear and smooth. Also I have exhaust valves always open in sport and s+ modes. Burbles are also disabled completely.

Ok .... so does Ecutek and flexport communicate to prevent potential user error of accidentally changing to an incorrect map on the fly? For example, if wifey filled up the tank with 91 octane and you switched to your E30 file, some sort of safeguard is triggered?

Also can you elaborate on how ecutek works for DCT transmission tuning?

Thanks!

If you're running a flexfuel enabled map the vehicle will calibrate to the exact ethanol content. If you're not using a flexfuel enabled map then there is the oe bmw failsafes which would be the same as a stock car and trigger a DTML due to high fuel trims.

All my 4 maps are flex fuel based...and this isn't like BM3 where you run a E30 file.

There is currently no DCT transmission tuning at the moment with Ecutek but I believe it's on their list for future expansion.

I'd be curious to talk to you offline.

Commanderwiggin,

Do you have any specific info on the ethanol sensor install? Locations, wiring, etc? Also who did you purchase through if you don't mind?

I came up with the design as other vendors were overcharging for a sub-bar fuel line/sensor kit. My good friend actually installed my kit while I was away at work and he now sells everything as a kit. He doesn't have it listed online but if you contact james@redlandsmotorworks.com he can put together a kit.

Kit includes Zeitronix ECA2 Canbus, S55 hose kit - plug n play adaptors (no hose cutting and PTFE stainless braided hose with excellent fittings), and Flex sensor. Last I heard he was charging 500usd+shipping.

As for the locations/wiring/install I tied into the FEM on the same location as the OE BMW Car Eye taps into for power and a couple of the other pins to tie into the CANBUS. If you buy a kit or get tuning through Bend Calibration I can provide that info. I get no kickbacks but both these folks are friends and I like to support their business.

[tomlong]

Can you also put a call into Ecutek and see why the Nissan guys get the rolling anti-lag in their suite but not us

[tomlong]

Just pulled the trigger on this. Should be tuned and running flex fuel within 2-3 weeks. Will report back on product review.

Who are you using for your tuner? Please update us with your impressions and results. Thanks!

Alexander Roy @ Performance Eurowerks. Local shop here in Chicagoland where I reside.

We believe that Ecutek allows him to truly recalibrate the ECU to make good, safe, and consistent power.  Unfortunately, at the moment, they don't have rolling anti-lag, which I really want but they've developed it for the GTR, Z, and Subie market.  I can only imagine that they'll do the same for the BMW/Supra market at some point...hopefully!

I went with Alex because proximity is also important to me, from a tech support standpoint. I know there are a lot of great tuners out there and virtual dyno sessions have become the new thing. But the tech support, especially from both a software and hardware perspective, is vital for me. This is based on my past learnings and experience with my 24v VR6 turbo project a decade ago.

It's just going to be a mild Stage 0.5 tune w/flex fuel sensor to allow the car to properly run a range of 93 octane, E30-E85, to Race Gas. No down pipe yet as my state inspection is just around the corner in Sept this year. I will do my best to also shed light on how to manage E85 for reliability.

Alex and his shop have done a great job dialing-in my car's suspension, maintenance, and are local. I've had the car running on KW V3s now for 39k miles with zero issues. Car sees 100mph+ daily and is driven through Chicago winters. Zero issues whatsoever except for the occassional need for alignments, new brake pads, new tires, etc. We all knew the consumables weren't going to be cheap on the F8x platform $$$$ right?

I'm finding that a 2nd gear rolling launch in my F80 DCT results in quickly running out of rpm. And launching in 3rd gear is outside of the car's "responsive" rpm band. This is based on 40k miles of actual driving experience in true stock form.

With that said, having more whp hopefully should offset the lack of rolling launch and gearing disadvantages, like your big turbo M3.

Brake boost is your friend for now.
