Pro128 Features & Information Summary
12 Injector drivers - All with built in Injector drivers!! Perfect for a twin injector setup on the Supra!!
16 Coil Drivers - Yes 16!!! No more waste spark!!
32 Analog inputs!!! - There are 32 analog inputs which will be preconfigured for anything you want to do... I.E. plug in a fuel pressure sensor and it automatically activates the trims associated with it. Put a Nitrous pressure sensor on your car and the computer trims fuel accordingly to bottle pressure!! You can datalog everything imaginable!!
10 Low side driver outputs - You can configure these to do whatever you can imagine. Also these will all support 4+ amps each!!
Built in wideband!! - That says it all!!
True volumetric efficeincy - So things like injector and pressure changes don't have to be calculated and multiple maps changed, it's all done in the background by simply entering your injector size and base fuel pressure. Actually knowing the injector size and fuel pressure, this allows us to make instantanious feedback changes to things like fuel pressure not staying constant, without relying on the O2 sensor for delayed information. Changing fuel type is as simple as entering the stoichiametric ratio for the fuel used.
Fault coding - Check engine light will tell you fault codes to help diagnose problems. Actions can be assigned with the fault codes. I.E. low oil pressure triggers a fault code, and activates a low rpm limiter. O2 sensor faults will automatically turn off block learning and closed loop feedback. Also the fault codes will be the same as the original ECU!!!
Traction control - multiple comprehensive traction control strategies including defined wheel speed differential between driven and non-driven wheels.
True knock sensing capability with specific knock frequency detection based upon the specific engine being monitored.
Multiple failsafe conditions making it nearly impossible to damage your engine in the case of tuning errors or mechanical malfunctions. I.E. lean, and knock conditions can be used to turn off nitrous, shut down boost etc.
O.E.M. manufactured ECUs - The ECUs are built by an O.E. manufacturer, so all ecu are 100% tested for vibration, temperature, loading etc. BEFORE you install them into your vehicle. Pro EFI ECUs are as reliable as the factory units you take out. No more being stranded on the side of the road, or waiting weeks or months to get and issue repaired with the confidence of rolling the dice.
Drive by wire capability!!
Up to 4 stages!!
Control by speed, time, gear etc.....
Just enter the number of jets, jet size and target a/f and it does the rest!!
Add a nitrous bottle pressure sensor and it adjusts accordingly to pressure!!
Unlike other ECU's, you can target different a/fs for Nitrous with this unit in closed loop, or open loop, since the computer is based soley on V.E. it doesn't rely on the O2 sensor for hitting the desired a/f ratio. It does this based upon volumetric efficiency and desired equivalency ratio. Therefore there is less work for the O2 to do in closed loop, eliminating the chance for lean spikes typical of running nitrous!!!!
Fuel pressure compensation:
With the simple addition of a fuel pressure sensor, the computer will monitor and compensate for various fuel pressure. Lets say that you have a pump that is tired and your fuel pressure is not rising 1-1 any more. The computer will know and add neccessary fuel. Also if the pressure really gets unstable causing the computer to add too much pulse width, it will trigger a check engine light. It can also be set to initiate fuel cut, turn off the boost control, shut off NOS and lower the rev limiter. These safe guards can be triggered by the fuel pressure alone, by O2 activity or a number of other things!!
Boost Control Strategies:
Will be able to utilize dual solenoids to control pressure to both the top and bottom ports on any wastegate. This will give you VERY accurate control!!
Will be able to control boost by speed.
Will be able to control boost by time. Therefore if you spin the tires, and the vehicle speed sensor puts the boost map into a zone for higher boost.... the computer will know that it is wrong and hold the boost down until a certain amount of time.
Will control boost based on traction control. Traction control will be based on wheel speed differential!!
This computer will also know what gear you are in by simply entering gear ratios from the service manual, rear end ratio and tire size!!
Lean condition safety features:
In the case of a lean condition under certain circumstances (IE load, time etc) the computer can be programmed to shut down nitrous, lower boost, initiate fuel cut, initiate a rev limiter for a programmed duration of time until safe conditions return. This can also then be programmed to throw a code and activate the check engine light.
No more guessing if you have a misfire. This computer will tell you which cylinder and how often it misfires!! Think about how valuable this will be!! You will know instantly when it is time for new plugs.... or a coil pack is going bad....etc!!
20 channel thermocouple capability:
Yep..... 20 channel!! Put one in every runner..... downpipe..... anywhere you can think of!! This is critical in tuning an engine to run exactly the same on every cylinder!!!
