The Best SR20det Standalone Engine Management Systems

Here at Brewed Motorsports we’ve always had a soft spot for the SR20det. No matter the chassis, the little turbo SR20 is a great platform.

When it comes to making reliable power a big step for any car enthusiast is moving into a standalone ECU. We’ve done the hands on track testing with a huge range of ECU’s and ECU packages to help ensure we have the perfect standalone package for your SR20det goals. 


Below is a list of the best ECU packages and options available for the SR20 engine.

Yes, there are still other options like the Power FC, (we still offer E-tune services for the Power FC) but it is a very outdated ECU with extremely limited functionality (and safety measures) when compared to the modern ECU options listed below. 


Link ECU SR20det Plug In

With the most budget friendly option we have the Link plug & play SR20 ECU.

They offer two options being the 76 pin plug and play ECU and the 64 pin option as well (covering S13, S14, and S14 SR20det engines).

One noteworthy thing with the Link ECU if you want to run extra sensors you do have to buy their Link ecu expansion harnesses and to run CANbus communications you have to buy Link CANbus adapter harness, you can run things like your link canbus Wideband or even an AEM CD7 digital dash with the CAN adapter harness. These adapter harness options make for easy install/smooth trouble free installations.

We also support tuning for the Link ECU to make the transition to your new Engine Management System even easier.

Discontinued AEM Infinity ECU

**AEM Infinity 506 Discontinued 2023

We highly recommend using our Haltech Elite 1500 or Link ECU package over the AEM Infinity. Both the our Haltech and Link ECU packages offer the same motorsports functionality the Infinity ECU offered.

The Infinity ECU was discontinued by AEM/Holley in 2023 so there will be no continued support for these ECU’s if there are any problems.

The now discontinued AEM Infinity SR20 ECU packages were a clean simple option that delivered huge motorsports functionality right out of the box with a very affordable price point. We run this exact package on our SR20det swapped BMW E30 shop car.

This package includes the Infinity 506 ECU + adapter harness to your OEM harness: The adapter harness has an integrated 12 pin DTM connector for future expansion like fuel pressure, oil pressure, oil temp, MAP sensor, or intake air temp to fully convert to speed density and get rid of the restrictive MAF.

The Infinity 506 ECU also has a built in wideband o2 controller which allows you to run a 4.2 LSU O2 sensor directly off the ECU.

Rolling launch, anti-lag, flex fuel and DBW support are all fully supported by this AEM Infinity ECU package.

Needless to say, we offer AEM Etune services for the Infinity ECU.
