MastMotorsports

Mast Motorsports is announcing the release of our stand alone EFI systems!!! We have had lots of demand to sell our ECM/Harnesses separate from our crate engine program and we are finally doing it. These are based on a modeled airflow speed/density control logic eliminating the need for a Mass Air Flow Sensor. We currently have fully calibrated kits available for the following applications:

I KNOW WHAT YOU ARE ASKING AND, YES, THESE ECM PACKAGES ARE AVAILABLE WITH VARIABLE VALVE TIMING (VVT) CAPABILITY!!! These kits work great for LS2, LS3, LS7 guys as well as those wanting to do VVT engines like the L92, LY6, or L76.

These ECM packages include the following:
M-90 ECM
Main Wiring Harness w/Integrated Fuse Block
Dash Harness
MAP/IAT Harness (Choice of Delphi (LS1, LS2, LS6, LS7) or Bosch (LS3, LSA, and LS9) MAP sensor configuration
IAT Sensor
Mast Motorsports Air Filter

M-90 ECM Package Price---$2146.21

Options:
Calibration Software and Communications Cable---$199.95
Fuel Pressure Correction Kit---$230.38
Bosch Narrow Band HEGO Kit---$54.95
NTK 7 Wire Wide Band O2 UEGO Kit---$299.95
A/C Harness---$19.06
Fuel Pump Harness---$31.69
Electric Fan Harness---$45.00
GM Foot Pedal---$69.99

Less Wiring For Your Project

This ECM package provides the user more capabilities than most other options currently available in the aftermarket. With the fuse block integrated into the harness wiring for the following subsystems are already done for the end user:

Ignition Relay and Wiring
Starter Relay and Wiring
Fuel Pump Relay and Wiring
Electric Fan Relay, Wiring, and Control Strategy
A/C Relay, Wiring, and Control Strategy

What this means is that when you install the ECM package there are 5 wires to hookup under the dash and the engine runs. This makes for the simplest installation on the market. With the additional wiring for your A/C system, the M-90 ECM will cut the A/C compressor off at high engine speeds as well as wide open throttle conditions.

Calibration Software

These ECM kits come fully calibrated for most engines. This eliminates the additional cost of tuning and calibration services for your project. However, as stated above, calibration software is available making this package fully programmable. This works really well for the guys doing a custom combination for their project.

Wideband O2 Kit

Our Wide Band O2 kit is a true plug and play system. It plugs directly into the main wiring harness allowing the end user to read fuel mixtures directly off of our software. This eliminates the extra boxes and controllers sometimes needed for Wide Band capability. Since the Wide Band O2 is embedded into the controller itself, it can be used for closed-loop fuel control as well.

Drive-By-Wire Throttle

The M-90 is capable of taking advantage of drive-by-wire (DBW) throttle technology. Using this technology makes for better idle behavior and eliminates the clutter and routing of a cable for a non-DBW throttle. It also eliminates the need to buy an expensive cable driven throttle for your project budget.

Gauge Drivers

The M-90 ECM’s Tachometer, ECT, and Oil Pressure gauge drivers allow you to run your aftermarket electronic gauges with no additional sensors, thus, eliminating the extra plumbing and wiring that is normally necessary.

CAN Gauges/Transmission Control

The M-90 also has Controller Area Network (CAN) Bus capabilities allowing for two wire communication to CAN compliant systems. This includes Mast Motorsports CAN gauges as well as a TWO WIRE HOOKUP TO A TCI TRANSMISSION CONTROLLER!!! This allows for hassle free 4L60/4L80 conversions that are fully user configurable. This means that the end user can calibrate for economy or aggressive shifting at the flip of a switch.

The M-90 is the only option for a standalone ECM on the market that is capable of Variable Valve Timing as we are the only company using this technology for performance gains. Dyno testing has proven the huge gains available with VVT technology. See the link below:

The M-90 is the most straightforward, capable, and headache free ECM option on the market…PERIOD!

Yeah, I'm interested as well - but if it's ALSO $3,000 for a comparable package... Well, it'll be a while before I'll be able to consider it...
