My New X1 B48 has Port Injection from the Factory

I'd expect the B58TU2 to have the same.

Well, shit. Maybe we can retrofit.

I doubt it would be worth it. The Mk7 Golf Rs outside the US also had PI while the ones in the US only had DI. Didn’t really do anything for power but it did keep their valves clean.

Only if you drill ports in the head/head swap.

DI Injectors are so incredibly limited. lol.

Found the info:

The new B58TU2 engine uses the Miller cycle for increased efficiency and features redesigned intake ports and combustion chambers, an electronically controlled Vanos variable camshaft timing system, and an ignition system featuring an active coil with integrated electronics. The turbocharging system including the intercooler has been optimized, while the cylinder head and exhaust manifold are now one integrated component, as they were on previous lower-output versions of the B58TU1. This is in contrast to the 382-horsepower B58B30O1, which uses an exhaust manifold with an integrated turbocharger as opposed to a cylinder head with an integrated exhaust manifold.

he Valvetronic fully variable valve control system for the intake side has been democratized to the exhaust side of the cylinder head with switchable rocker arms, allowing exhaust gas exchange to be interrupted if so desired. This allows the engine’s frictional torque on overrun to be reduced be approximately two thirds, which increases the amount of energy recuperated by the accompanying standard 48-volt mid-hybrid system when the accelerator pedal is released and the vehicle is coasting, and during braking. The Vanos variable camshaft system, previously operated by pressurized oil and solenoids since its introduction over 30 years ago, now works electronically.

In addition to the cylinder head being integrated with the exhaust manifold, on the intake side of the equation, BMW has added another set of low-pressure fuel injectors to complement the high-pressure direct-injection array. BMW isn’t the first manufacture to adopt a dual injection system on primarily direct-injection engines, because the benefits are obvious. Running a set of conventional fuel injectors before the intake ports reduces both carbon emissions and particulate formation, more commonly known as carbon buildup. As many N54 and some N55 owners are aware, carbon buildup on the intake ports and valves of the engine eventually robs the engine of power and harms efficiency, because there’s no fuel to effectively clean these parts as on a conventional engine.

They really are. I doubt we’ll be getting extra power from PI installed from factory, though. Obviously aftermarket stuff is another story.

I’m happy to be proven wrong though.

Im less interested in the actual BMW implementation of where the port injectors are, and more interested in the ability for the BMW ecu to natively control them.

Wondering if this is coming for '24 or '25

The B58TU2 is first being used in the X7 xDrive40i and the new 740i.

democratized

Interesting choice of words here.

So Zack you replaced the X1 with a new X1 or just sharing the info now

I read that same article. I'm saying I'm wondering when the Supra will get it. My guess is '25 at this point since we haven't heard anything about '24 bringing any new additions.

I think the supra goes out of production around then. So I kinda doubt we would get it. But who knows, Toyota keeps changing shit.

Maybe Toyota uses it for the rumored GRMN edition to send it off with minor power bump. Makes a lot more sense than the S58.

??? So what, big news is ~45hp? ?
