This may not be news to many of you, but I messaged Fabian at MHD and he said it was possible to run E85 with no other modifications than their stage 1 set to E85. Has anyone done this and experiences a noticeable performance improvement?

Do you have a gen 1 or 2 b58? What sort of performance do you want? They are just tuning around your stock fuel pump limitations, as ethanol requires moving more volume of fuel for the same power output.

Try it, pull road logs and load into the virtual dyno and compare before and after.

Try to stay on flat surface as much as possible during data logging.

Maybe try the E30 map first?

My car manufacturer date was 1/19…B58B30M0: 265 kW (355 HP) version
Edit
Applications:

2017–2019 G01 X3 M40i[17]

I assume that is gen 1 but strangely unsure

If you have the live cluster then you have gen2 b58 (O1 and not the gen1 b58 M0).

If you really want to be sure, then open up the engine cover and look at the orientation on the HPFP wire.

Sorry …"live cluster" is instrumentation? What should the orientation of the wires to hpfp look like exactly?

Thinking I have gen 1 with 355 HP

IÂ’m pretty sure you have a gen1 just by manufacture date and engine code. But, to be sure, if the top of your hpfp is dimpled you have a gen1.

Are you doing it for saving some cash at the pump, or performance?

If for saving a few bucks, might be worth it. As mentioned, your engine will burn through a tank of E85 faster than 91/93, so it's a bit of a trade-off.

If for performance, I would say, don't. It seems the general consensus that past a certain mixture of E, it is not beneficial to performance. Somewhere between E30-E50 seems to be sort of a sweet spot.

And if MHD says they can do it, then I believe they can do it. I think your B58 still had the lower volume fuel pump that doesn't supply as much as the B58TU (MY20+) fuel pump does. That probably isn't even a factor at stock or mildly upgraded/tuned.

Definitely performance. MHD does have a Stage 1 map specified for E85 and trading emails with Fabian at MHD has put my mind at ease about running this setup. That said if I drop too low on the MPG that will be a pain.

I filled up with Propel E85 today and am now running the Stage 1 E85 map. Have not had a chance to drive it hard. Car definitely has a smoother idle. And I filled up the car for $75…no small thing in CA. We have good E85 coverage in state. Unless I run into fuel pump issues this feels like a really great and easy bang for buck upgrade with a 2019 that is still essentially stock.

Stage 2 will give you room for a bigger turbo later. Good idea to go with their flex fuel kit also. You are so lucky to have access to pump E85, but I have read that not all pump E85 is 85% ethanol and this way you can ballpark a mix yourself at the gas station for around E50 and the tune will always self adjust.

Any consensus on best flex fuel kit today?

I have not been able to compare others but I know the dorch and obviously mhd kits are well integrated with mhd. Any kit that communicates the content with the dme via canbus.

Double have you or anyone else upgraded a fuel pump in isolation and felt that holy shit that made a huge difference? I ran my car today hard, and for what it is worth, I didn't necessarily sense "damn the 1st gen fuel pump is not keeping up", but then again I am not going to know anything until I try it and what the hell do I know. I will pm you

Its very easy to know when your fuel pump
Is not keeping up.
Full throttle 3rd gear or higher your car feels like you hit a brick wall and you get a drivetrain malfunction. No guessing there.

Everything builds and adds up. The hpfp alone will do nothing for you, especially on CA91. You will struggle to make much more than 400whp on 91 octane and your stock hpfp cannot pump 480whp worth of E50 like an upgraded pump is able.

Good god, when will Dorch have this back in stock !!!

It's been showing out of stick the moment it went on sale, day 0.



I don't think there will ever be a PnP like F-chassis gen1 b58 for G01 to install at the low pressure fuel pump... So something next best thing like this from Dorsch would be the way to go, i would think.

It was available for a small window, but they weren't sure about the X3´s firewall access so they made it unavailable. I know this because I ordered one. I think you should email them.

I ordered a Dorch 2 pump. There is a company that partnered with Chevron in CA called Propel Fuels which provides only E85 and High Performance Diesel at separately branded pumps within a Chevron station. Propel's diesel is the best available in the US…equivalent to the super premium diesel sold in parts of Europe. Propel's E85 also has a good reputation. Bio fuel subsidies at work in Ca.

Let us know how it goes

Yeah, crap. Reply from them is that the included ECA to CAN module for G01 X3 (why though ???) is being reworked and basically need to wait. No mention though on the access to the G01's firewall.

Looks like the use of BT ECA is still the way to go for me and manual blend calculations, for a while.
