AEM Infinity 506 Stand-Alone Programmable Engine Management System

THE SERIES 5 PLATFORM
The Infinity 506 and Infinity 508 ECUs are affordable state-of-the-art engine control units designed for four- and six-cylinder racing engines (typically Infinity 506), and racing engines with up to 8 cylinders that are using high-impedance injectors (Infinity 508). A Powersports version is available for Polaris RZR 900, 1000 and XP Turbo applications (PN 30-7112). The Series 5 features a smaller footprint than the Infinity Series 7 at 5.855” x 5.55” x 1.8”, and has a single, weatherproof 80-pin connector.

Infinity 506
The Infinity 506 is designed for racing engines with up to 6 cylinders.

Infinity 508
The Infinity 508 is designed for high performance V8 crate engines and race engines using high impedance injectors with up to 8 cylinders. A special Powersports version is available for Polaris RZR 900, 1000 and XP Turbo applications using Plug & Play Adapter Wiring Harnesses specific to each application.

SELECTING THE RIGHT INFINITY ECU
Infinity ECU modules are designed for maximum flexibility across many types of applications. ECU modules and harnesses are sold separately for both Supported and Plug & Play applications. Choose the ideal Infinity ECU based on your application’s ignition and fuel injector output requirements using the Infinity Specifications Chart, and then choose between our available Plug & Play or Universal harnesses to create the Infinity solution that suits your specific needs.

SUPPORTED vs. PLUG & PLAY APPLICATIONS
The Infinity ECU delivers comparable tuning functionality regardless of application type. It is available for a wide variety of applications in two distinct forms:

Supported Applications

  • Infinity Supported applications refer to an engine family or cam/crank pattern for which the Infinity ECU has been tested and validated to run. However, certain ancillary vehicle systems (such as factory instrument clusters, automatic transmissions, and certain drive by wire throttles), may not be supported.
  • The setup Wizard included with the InfinityTuner user interface software dramatically simplifies initial tuning configuration to help ensure successful initial startup for Supported applications.
  • Wiring is required for Supported applications. AEM offers Universal wiring harnesses in several iterations and detailed application-specific wiring instructions/schematics.

Plug & Play Applications
Infinity Plug & Play applications are available for select vehicles. Plug & Play applications support a vehicle’s engine and most other ancillary vehicle systems, and include application-specific start up calibrations. The Infinity Plug & Play harness (sold separately) connects directly into the vehicle’s factory ECU harness and requires no additional wiring.

200MHz Processor and Real Time Operating System
Late model vehicle ECU’s all run on faster processors. The Infinity ECU is built around a latest-generation 32 bit floating point 200MHz automotive processor and Real Time Operating System (RTOS), which is capable of processing 400 MIPS (millions of instructions per second). By comparison, common competitive systems typically use 20MHz to 50MHz processors. To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This allows the Infinity to do more, faster, in a more stable programming environment.

  • The Infinity’s 200MHz processor and RTOS makes the Infinity more responsive, for a better driving experience
  • The Infinity’s 200MHz processor and RTOS allows for more accurate ignition timing, which enables an engine to create more power
  • The Infinity’s faster proc...

Nice economy casual sweater,
Size: Large, Color: Off-white
The sweater is fine for the price, with correct fit. Arrived fast. Nice neutral cream/oatmeal color. It has a fairly loose open weave and is predominantly cotton, so it’s quite breathable and well suited for layering in cool but not truly cold weather. The knit is a little coarse, not really scratchy but not very soft. It’s a good value for what they charge. And fine for casual wear. But I ultimately decided to return it and spend a lot more to get a merino wool sweater because they are dressier, much warmer for weight, MUCH softer, and less bulky under a jacket. I like to wear mock turtlenecks under a sport coat in the fall and this sweater was a little too thick for that.

Soft and comfortable but runs a bit large
Size: Medium, Color: Off-white
I got this turtleneck in the off white color, and it looks very clean and easy to style. The color is true to what is shown and works well with casual or more dressed up outfits. The fabric feels soft and has a nice amount of stretch, which makes it comfortable to wear for longer periods without feeling stiff. The sweater feels lightweight but still warm enough for cooler days. It is not heavy or bulky, so it layers easily under jackets or coats. It also seems fairly wrinkle resistant. After wearing it and folding it, it still looked neat without needing much adjustment. In terms of fit, it does run a little big. I usually wear a medium, and while this one is still wearable, it feels slightly looser than expected, especially through the body. It is not a big deal, but I would probably order a smaller size next time for a more fitted look. The turtleneck itself sits comfortably around the neck and does not feel tight or irritating. Overall, it feels like a comfortable and easy to wear piece with good stretch, a nice lightweight feel, and a clean look. Just something to keep in mind on sizing if you prefer a closer fit.

Don’t recommend
Size: Medium, Color: Black
Got this as a last minute shirt for an event and it was roughly $12 on sale. The quality was ok, first wear was fine but it doesn’t hold up after washing and air drying. I don’t recommend unless only wearing once, there was a lot of shedding and pilling after the first wear. I’m rough 5 ft tall and about 140 lbs. and I got a M and it sat around my hips so unless your on the tall side this wouldn’t fit.
