A Big BMW Feature Is Coming Back! Huge Power!

In this video, I take you through the exciting process of upgrading my 2019 BMW 330i. I've recently installed a turbo upgrade and I'm gearing up to tune it, which led me to explore the world of port injection for my direct-injected car.
Ever wondered why BMW reintroduced port injection in their 2023 models alongside their direct injection? I'll answer that question in this video while discussing how I plan to optimize port injection using the controller we're implementing.
Join me as I walk you through the installation of an essential port plate that fits snugly between the intake, manifold, and the engine. I'll also guide you through setting up a controller that communicates with the DME, enabling port injection for supplemental fueling, and making it possible to run on full E85 ethanol fuel.

Ever wondered why BMW reintroduced port injection in their 2023 models alongside their direct injection? I'll answer that question in this video while discussing how I plan to optimize port injection using the controller we're implementing.
Discover the benefits of port injection, especially at low RPMs and during low throttle conditions. Learn how it enhances atomization and potential cooling, and how it complements the 5000 psi direct injection fuel systems introduced by BMW.
I'll also share my insights into why I chose this approach over sticking with direct injection only, the cost considerations, and how this setup allows us to achieve around 500 crank horsepower while keeping costs under $5000.
The Motive Reflex Plus controller takes center stage in this video, offering full integration with ECUtek via the powertrain can bus. We're simplifying the process by using a basic software file to make the Motive controller obedient to the DME, ensuring seamless communication.
Watch as I explain how the Motive controller constantly monitors and optimizes port injection under various conditions, maintaining control even at high RPMs with ethanol fuel. Discover how this setup can provide efficiency benefits, even when running on 91 octane.
Join me on this journey of installing port injection and the Motive Reflex Plus to maximize my BMW 330i's potential. Whether you're a car enthusiast or simply curious about automotive upgrades, this video has something for you.

[@tlcj3838]

Having the dual style injection isnt new as toyota uses it in the Tundras. With the DI motor i think its brilliant. Since DI motors are prone to carbon build up on the intake valves having the secondary injector will alleviate these issues. Now some companies use a sodium filled intake valve like on the Kia Stingers. I say all DI motors should have this option. Thank you for sharing this build with us. This is some of the best BMW automotive content out there. Very clear and precise information. You are appreciated brother!!!

[@majedalameeri7089]

I think the v10s in gen 2 r8 and huracan have both di and port injection too.

[@guntrain212]

Interesting, considering Toyota's D4S system used port injection alongside direct injection. Port injection is typically best suited for high-rpm applications and for keeping the valves clean. Perhaps that was a consideration for BMW, after a decade and a half of DI turbocharged production.

[@CrowSaysMoo]

Do you know what the power limits are for the IPOS450 without running port injection? Thank you for all the comprehensive videos, really shedding light on B58's little brother.

[@VehicularDIY]

One of my maps is based on e40 to e50 with port turned off. I’ll go back to the dyno to see what it makes. I’m guessing around 400 whp mixed with 91 and might do 420 whp mixed with 93.

[@roterflieger8753]

420 wheel is about the max without the port injection as you’re approaching the limits of the stock direct injectors.

[@CrowSaysMoo]

I'm wondering if it's possible to achieve 450whp without doing port injection. Would upgrading stock injectors fill the gap in the fueling? I typically run an e50 blend.

[@postalpancho]

My main concern with building a B48 for this amount of power is heat soak. I got a lightly modified 230i, DP, tune, and intake. I already see temperatures climbing to 250+ with ease on track days and I have to pull over and let temperatures drop. Do you think an upgraded heat exchanger is enough to lower things back down or is there more that needs to be done with the tuning? While my BMW 230i already seems plenty fast for a daily, it is cool to know that there is a ton of room to increase power if I really wanted to, instead of trading for an M2.

[@Wolfpack310]

External oil cooler and bigger intercooler will give you lap after lap day after day no problems. Also a nice tune is everything, you don't want too run lean that's when egt will get high and pistons melt

I really enjoy the 330i video's, my personal favourite G20 model. As long as you keep the car stock cosmetically it will be a big win in my opinion! Even if you could go back to the OEM 330i kidney grill it will give it a more clean and traditional BMW look😊

I’ll keep it pretty much the way it looks now but might add in some front seats from a g80 m3. I miss them from the g80.

[@kevinsmb]

Thanks for the great info on combining PI and DI. It's cool to see how you’re integrating this to help with overcoming E85 fueling limits and its OEM application for the Gen 3 B58. What are your thoughts about using the Spool FX 350 HPFP and IFX350 injectors to get the most out of the IM450 on the B48 with E85. It seems more expensive but maybe easier to set up. What do you think about this approach? Looking forward to your thoughts!

[@VehicularDIY]

At first I was looking to go that route but the cost was too high and wouldn't be a good example to show you guys. With this build it was all about value for money. Once the spend becomes too high the argument of going with a 330i over an M340i is less compelling. My tuner recommended the port and told me all about the two-way communication and it became a no brainer.

[@rrokas]

Very interesting stuff. I’m eager to see more n54 stuff too though haha. Keep it up
