Getting Project STurdteen (S13) Running Right with an AEM Infinity PNP EMS and Wiring Specialties Engine Harness
by Rathyna Gomer
Hopefully, you've been keeping up with the steady progress of transforming my STurdteen into a reliable and worthy demo drift car. Powered by an SR20DET and with all of the new goods going into this build (see the new Turbonetics setup I went with here), I needed an adequate engine management system to handle engine control duties. The search for the perfect EMS didn't last very long because I soon discovered what I consider the best solution out there – the AEM Infinity Plug and Play EMS.
I selected the AEM Infinity 8H
for my car because everyone in the office said that this was the perfect system for my intended use. The heart of the AEM Infinity is a 200MHz processor that can perform operations at 400 MIPS. It can log 64 GB of data at 1 KHz. I am not sure what any of that means but the boss said it's all good!
The Infinity also has a sleek, sealed water and shock resistant enclosure and com ports. This can allow it to be mounted in the engine compartment if desired. The Infinity is multimap capable and has the capacity for tons of data logging. The Infinity ECU is very cost effective with a lot of capability for the price.
The small, lightweight design of the AEM Infinity also includes quad flat no-lead components (QFN) within its circuit board, which maintains good electrical and thermal performance and improved reliability in adverse conditions.
The Infinity ECU comes with everything you need to install it into an S14 240SX with an SR20 including AEM’s sealed, weatherproof Plug & Play harness includes a Lambda connector, an AEMnet connector for communication with other AEMnet enabled devices and an auxiliary connector with a High-Performance DTM-Style 12P connector for adding common aftermarket sensors.
This is the harness used to communicate to your laptop for tuning and data logging.
