Pro-M EFI Engine Management System for 86-93 Mustang w/ calibration

Complete Pro-M EFI system with choice of wideband and calibration from Pro-M. Please enter model year and engine specs above.

Wideband options above: Innovate MTX-L singe wideband (best for turbo applications with single downpipe) or Innovate DLG-1 dual wideband (single gauge, dual wideband sensors)

Pro-M MAF's are recommended, if you already have one we will send you a label to have it flow tested for a MAF transfer function for your system at Pro-M Racing.

Note* AFM may reach out to you to confirm any other details needed to complete a calibration for your system.

The Pro-M EFI Powertrain Management system is a Mass Air, sequentially fired, port fuel injection system, with full ignition control, and transmission controls, as well as a host of other features listed below. The Pro-M EFI system provides a combination of drivability and quality typically only found in the OEM, combined with a level of performance typically only found in the aftermarket. It is truly the best of both worlds. All provided in a package so easy to use, most anyone can become their own tuner.

The Pro-M EFI Engine Management System for 1987 - 1993 Fox Body Mustang includes our fully programmable Pro-M EFI PCM, tuning software and a custom Mustang powertrain wiring harness. Your New Pro-M EFI wiring harness will be made to fit your specific model year Mustang. It is not a universal harness. It installs in the car just as if it had been made by the factory, and uses all the same sensors, connectors and circuits as the OEM harness. It is not an "add-on" harness like you get from the other guys.  This harness replaces your existing EFI harness entirely.  We have several different wiring harness configurations made specifically for all Mustangs produced from 1979 through 2004. The harness can also be used as part of one of our complete EFI conversion packages. 

The new Pro-M EFI PCM will be shipped with the “tune” pre-installed. The customer need only enter some basic information about their specific application. These parameters can also be entered here at Pro-M for an additional fee if the customer desires. This tune will run virtually any engine right out of the box.  Tuning is neither required, nor is it recommended. The money you will save by not going to the tuning shop will actually pay for your Pro-M EFI system.  No one else can make this claim.

We will also include a software package that will allow you to make nearly any modification to your powertrain you could ever want and do so with amazing simplicity. The Pro-M EFI system can be as simplistic, or as sophisticated as the user wants it to be. Tune if you want to or leave it alone if you don't. Everything you could ever want in a management system is right here!

Features of the new Pro-M EFI system include:

The Pro-M EFI Powertrain Management system is a Mass Air, sequentially fired, port fuel injection system, with full ignition control, and transmission controls, as well as a host of other features listed below.

Water and shock proof OEM quality PCM. Made side by side with the OEM's. No one else does this!

OEM quality wiring harness. Installs exactly like the original harness, using all the same connectors.

Fully laptop programmable. Tune because you want to, not because you need to. Your laptop also acts as a powerful scan tool.

New improved calibration tool with multiple user levels. Tuning software so easy and intuitive, most anyone can be a tuner. Now compatible with both PC and Apple!

Store an unlimited number of tunes. 

Tune on the fly and see the results immediately.

OBD II compatible. Not only does your laptop act as a powerful scan tool, you may also read codes and sensor data using a generic OBD II scan tool. The Pro-M EFI PCM uses the same code strategy and the same codes that all the OEM's use!

Automatic transmission controls for AODE/4R70W/4R70E/4R75W/4R75E

Manual shift option. Use your cruise control buttons (94-2004 Mustangs), or your own switches to manually shift your automatic transmission!

Flex Fuel. Done the right way! Easily make big power on E85!

Traction control. Intergraded into the PCM! No parts to buy!

Advanced boost control for both turbo charged and supercharged applications, that actually works and is easy to use!

Launch assist.

Fully programmable progressive nitrous controls. No external controller needed!

Fully programmable progressive water/methanol injection controls. Done the right way. No external controller needed. Advanced OBD II diagnostics and fail-safe features make this absolutely the best water/methanol control system in the business.

Individual cylinder tuning.

Advanced timing control that actually rivals the accuracy and consistency of “Coil On Plug” high data rate ignition systems, while still using your distributor.

Supports OEM “Coil Pack” and “Coil on Plug” ignition systems. If the engine you want to run was originally equipped with “Coil Pack” or “Coil On Plug” ignition, we can run those too!

Ignition module problems are a thing of the past! The ignition module is integrated into the Pro-M EFI PCM. No more failed TFI Modules.

Able to run two Mass Air Meters simultaneously. No limit to the amount of power you can make!

Easy, user adjustable two stage Rev Limiter. Cut fuel or spark or both.

T-56 Reverse lockout control.

Adaptive fuel control.

Adaptive idle controls.

Fuel pressure compensation.

Fuel pressure warning.

Electric cooling fan control with Soft Start feature.

Cooling fan cool down feature.

User programmable outputs.

“Decel Fuel” feature cuts fuel while decelerating. Saves fuel!

Operates in continuous closed loop with TWO wide band oxygen sensors (not one sensor like the other guys), which adjust each bank independently, resulting in the most precise control over air/fuel ratio in the industry.

No special tuning required for forced induction. Our “Load” based system makes forced induction super easy.

Advanced data logging feature built into the software.

Automatic updates for the calibration tool and user manuals.

Self-protecting PCM. The Pro-M EFI PCM detects short circuits and will shut down that PCM driver if a short is detected.

We cannot stress this enough...The real beauty of the Pro-M EFI system is that it can be as simplistic, or as sophisticated as you want it to be. It works perfectly right out of the box with some simple data entry, but if you want to tune, you'll have the most powerful tuning software ever offered anywhere by anyone, and OEM quality components that will last a lifetime. 

If you want the best, look no further. There is simply no other management system that offers the quality, features, reliability, and ease of use that we offer with the Pro-M EFI engine management system, period...
