Description

MS3Pro EVO GM LS 24x Plug and Play includes an MS3Pro EVO ECU, TunerStudio software and the most rugged & durable GM 24X custom harness in the aftermarket.  

Experience the MS3Pro EVO.

MS3Pro EVO is an evolution, not a revolution- a scaled up, more capable MS3Pro due to shared technology with big brother, MS3Pro Ultimate.  EVO does not have peak and hold injector drivers, but it does share some increased I/O, an on-board 4-bar MAP, barometric pressure sensor, and 5 diagnostic LED’s.

No need for a separate data acquisition system, EVO will log more than 64 channels, conservatively, at 330hz. The advanced TunerStudio software provides an intuitive, straight-forward tuning experience for pros and enthusiasts alike with best in class self-learning, self-tuning fuel table strategies to assist you.

MS3Pro EVO controlled the early hemi awarded ‘Best Appearing Engine’ at the 2017 Engine Masters Challenge presented by Amsoil.  HOT ROD ARTICLE HERE

Visit MS3Pro EVO product page for a complete features list–  Experience for yourself why more and more racers and performance enthusiasts are recognizing and choosing MS3Pro over the competition.

The MS3Pro EVO GM LS 24x Plug and Play Harness is the highest quality, best value option for LS Motors in the industry today.  Save your hard earned time and money while experiencing the virtually limitless feature set of MS3Pro EVO Engine Management System.  Simply choose your injector style from the drop down menu!

Professionally engineered and easy to install,  fire up your engine on day one!   All wiring is composed of TechFlex woven, self-extinguishing wrapped hi-temp TXL & GXL automotive grade wire with OEM Delphi & TE connectors. Reach the battery under the hood or in the trunk with 4 gauge power & 10 gauge ground wires.  All relays and fusing live in a single, waterproof fusebox and the fuel pump wiring / relays / fusing is big enough for pumps that can handle 1000whp or more right out of the box (10ga wire, 30amp circuit).  Additionally, all of the available I/O of the MS3Pro are brought out in the harness to make expansion as easy as possible regardless of the featureset you’re planning to use, allowing for killer features like traction control, bump box, table switching, flex fuel, and more.  This harness was designed with room to grow!

This harness also is designed for optional automatic transmission control using the AMP EFI CAN transmission controller; Be sure to choose the proper sub harness!

The custom MS3Pro 24x GM LS Plug and Play Harness is configured for a cable operated throttle body. The included connectors are set up for an LS1 style throttle position sensor and IAC valve. Four barrel style or independent throttle body setups may require modifications to the harness.

Note that the alternator connection is designed for high mount alternators such as Corvette and truck setups. Low mount alternator setups, as well as other aftermarket accessory drives that do not have the alternator high on the driver’s side, require our alternator extension cable.

  1. 5 out of 5

    Ms3 Evo 24xI first purchased the evo when it was first released. I was sold at the amount of features for the price. Since I have been so happy with this pcm that I have become a dealer and sold nearly a dozen!
    From a cam only ls swap all the way to my 7.8@177mph Camaro. I highly recommend this setup. It is easy to use and the possibilities are endless.
    Thanks DIY,

MS3Pro ECU Feature Comparison: 1st Gen – EVO – ULTIMATE

What is in the box?

    • MS3Pro EVOStandalone EFI Controller
    • LSx drop on wiring harness for LS motors with a 24x crank trigger
    • Fuse block with relays
    • USB and serial communications cables
    • Matching connectors for O2 and transmission / CAN subharness
    • Fuel pump ground wire
    • Includes TunerStudio registration code
    • USB drive (for software / documentation / base maps)

How big is the ECU?

    • The MS3Pro measures approximately 7″ long (including the mounting ears), 4″ wide, and 2″ tall including the mating connectors. Not including the connectors, the case itself is 1″ high.

Where is this product manufactured?

    • The ECU is manufactured in Gainesville, Georgia, USA. The wiring harness is also American-made.

What is the warranty on the MS3Pro?

    • It carries a one year warranty against manufacturing defects.

How watertight is the box?

    • The case uses an o-ring seal and sealed connectors to ensure it is completely splashproof, and will keep water out if completely immersed up to a few inches for a few  minutes (which normally shouldn’t happen, right?).  If you need further water submersion resistance that can be accomplished with a small bead of silicone just inside/outside of the o-ring.

Will I need to modify the harness to fit the mods on my engine?

    • This harness works with car, truck, and most aftermarket intakes that use a forward facing throttle body. Intakes that use a center mounted throttle body, independent throttle bodies, or reverse mounted intakes (with the throttle facing the bellhousing) will require minor modification.
    • The alternator connection is set up for an alternator mounted high on the driver’s side, like the truck or Corvette accessory brackets. Setups that mount the alternator low (Camaro, Firebird, GTO, and CTS-V, for example, as well as many aftermarket setups) will need an extension. Our alternator extension harness provides a good way to add this.
    • We anticipate most customers won’t be using the factory O2 sensors. We have brought these out to an Amphenol AT connector for making your own O2 harness.

What size screws do I need for the fuse box mounting?

  • It uses #10-32 mounting screws.

Does this harness have the MS3Pro controlling the alternator?

  • No. You will need to wire the alternator to the charge lamp. That will activate the alternator. See details in the manual.

What sort of throttle body do I need?

  • You will need to run a cable operated throttle body. The connectors included will plug into an LS1 style throttle position sensor and IAC valve.
