The ProEFI Pro128 ECU holds the record for bang for the buck. From it’s environmental specs, more inputs and outputs than you’ll probably ever use, to being hands down, the most reliable ECU you’ll find on the market at ANY price!
The Pro128 uses the superfast MPC565 56mhz Processor
12 Peak n Hold – with calibratable peak time. 6 – 6/2 amp, and 6 3/1 amp.
16 EST Ignition outputs
Low Side Outputs
10 total – 8-10 amp capable – 2-2 amp capable*
The Tachometer will also display information such as current Rev limit setpoint, and current I-Boost setting based on input from the cruise stalk.
High Current Bridges
3 channel sets – Used for Stepper motor control, or Electronic Throttle Control
Expansion module capable
Versioin 5z and later firmwares allow this module to use CAN based Expansion modules for additional I/O
Main Relay Control
34* Fuel Pressure monitoring and feedback correction, Oil Pressure, Exhaust Backpressure Feedback and correction, fault management with each input
8 channels – Fully programmable pre configured
Digital or VR
Digital or VR
10 Additional Frequency inputs are available (Speed1, Speed2, And DG 1- 8) Can be used for Turbo Speed sensors, additional Wheel Speed, Frequency Mass Air, etc…
No – Not needed – Stored permanently!
Limited to Fault logic
USB Direct Connection
Mass air (both frequency or voltage), True Speed Density via map or Throttle based V.E. APC based igntion timing , or Standard MAP based, even with Mass air!
Can control duty based alternators
ProEFI’s State of the ART antilag is unmatched in the industry! The ECU automatically adjusts timing and fuel to precisely control boost while staging. You can even control below your base spring pressure!
Automated Starter Control
The ProEFI can be setup to control the starter like a modern vehicle…once key cycle engagement and the computer will run the starter based on parameters that can be defined.
Most comprehensive and Accurate Boost Control and Antilag on the market. Multiple control strategies.***
Yes – Hall/VR capable
The Converter Dump feature allows you to control converter charge to stage with more rpm against a tighter converter.
Yes – Hall/VR capable
Cruise Control(Pit Limiter)
Comprehensive Cruise Control (Pit limiting)
Drive By Wire
Yes – Dual capable*
Drive Off Assist
Drive Off limiters to help with light rotating mass and grabby clutches. This also is used for variable two step control, more throttle is more limit rpm!
Drivers Information Light (Shift Light)
The Drivers information light allows the user to define when the light activates by rpm per gear, boost, vehicle speed, brake staging, and more. Makes the shift light intelligent to precisely control the driver based on Conditions
Control multile fans with user defined temperature inputs (Coolant, Oil, trans, etc…) Also Control Pulse width Fan control modules directly for Pulse driven Fans.
ProEFI introduced Fault management in to the aftermarket over 13 years ago, and to this day still has the ONLY comprehensive Fault management strategy on the market (See Fault management for further details)
Flex Fuel Capability
Add a Flex fuel sensor, and the computer automatically adjusts fuel, timing, and boost based on Ethanol content! Blend Target A/F, Spark, Accel fuel, etc… Multiple Failsafes!
Fuel Pump Control
Stage up to 3 fuel pumps, as well as controlling Pulse width duty controlled Fuel pumps
High Cam lobe control
Control high lift cam(V-Tec) activation based on several paramters
Pulse Width, Stepper motor, and ETC (DBW) – Adaptive
Ignition Timing Maps
Low and High Octane map with function blending or switch activated. Split ignition for rotaries. Fault management to default to low octane maps for safety.
2 Programmable frequency and event with individual cylinder notification
Comprehensive Launch Control Strategies to get the most powerful cars down the nastiest tracks!
Yes – Frequency and Voltage
Yes – Unlimited Range
The Check engine light is tied to any fault or condition and is user defined on what will trigger this light. This strategy can be set to force a clear or hold fault conditions, as well as display codes via MIL flashing digits. (see Fault Manager for comprehensive descriptions its capability).
4 stages progressive multiple event trigger control range. V.E. based fueling****
Multiple – Burnout, Stage, TwoStep, Strain Gauge, Launch Control, Traction Control, and Rolling Antilag (True RPM capture at ANY Speed) All tied to separate boost targets!
Rolling AntiLag Control
Speed based capture (no preset rpm or speed…press it and go)
ProEFI’s State of the Art Staged injection control makes it SUPER simple for the user to setup staged injection with no tuning needed. You can even stage in from pump fuel to straight methanol based on engine load!
Yes – Adaptive
Differential Wheel Speed, Driveshaft Speed, Accelerometer input for lateral power reduction, and more Multiple control strategies.***
Trans Brake Staging Control
Controls the final staging to the second bulb via trans brake ‘bump’ in via trans temp and duty cycle for SMOOTH staging.
Comprehensive Transmission Control over any switch Logic solenoid to shift (no linnear trans solenoids) such as 4l60/80, A340 toyota, etc… Converter lockup control with min/max gears and rpm windows for smooth engagement. Full line pressure control, monitor converter slip with no additional Sensors (ECU automatically calculates this). Sequential Gearbox control for drag racing (control the aspects of each gear change based on multiple parameters).
Two Stages – Tied to Fault management – Power Reduction, Speed limited etc.. No laptop connection required to active or deactivate, calibratable procedure
Yes 2 cam capable
2 Built in UEGO controllers (Inputs for External wideband capable)
The ProEFI Pro4 CAN Display Logger allows the user to monitor over 30 channels through a 4" color screen. Which can display up to 4 gauges at one time, with peak and hold min and max values. There is also Knock screen and a Fault screen. Users are also able to change the layout and have multiple user modes to give it a more personal touch. User defined units are selectable as well. This display also logs to a FAT32 formatted USB stick, ALL available CAN channels with logging triggered from the ECU software setup. Never miss any data again!
* If your Display only has 1 Aux port on the back, you have a Non-Logger Display
