We have compiled a master list of the features and functions that are available to the end user with the ProEFI system. This is just a summary of the information posted in the other threads.... all combined for easy reading!!

We at SP have had a long standing relationship with ProEFI and being a Master Distributor for this incredibly advanced Engine Management solution. The search has ended, look no further.

ProEFI Master Features List

12 Injector Drivers
All with built in Injector drivers!! This is perfect for any application up to a V12 or even for a twin injector setup on any application up to 6 cylinders.

16 Coil Drivers
Yes 16!!! No more waste spark like offered in many inferior competitor products.

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!! We use these to control multiple fuel pumps or even to control our Quick Spool Valve operation. There are lots of options here.

Built in wideband!!
That says it all!! The ProEFI utilizes a highly accurate NTK sensor for maximizing tuning capabilities that is highly resilient to E85 and race gas fouling.

True Volumetric Efficiency
Unlike a number of other engine management systems offered, the ProEFI uses a real VE Table . This is done so that 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. No more look-up tables!!! Actually knowing the injector size and fuel pressure, this allows us to make instantaneous 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 stoichiometric ratio for the fuel used.

Fault Coding
Fully functional check engine lights (CELs) 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!!!

Fuel Pressure Compensation
With the simple addition of a fuel pressure sensor, the computer will monitor and compensate for various fuel pressures. This is easily one of the most functional and useful safety features built into the ProEFI system. In the event of any lean condition whether it be a failing fuel pump, clogged fuel injector, or any other similar fuel pressure related problem, the ProEFI will recognize the problem and widen injector pulse width in order to put you're A/F Ratios in the safe zone again. If a safe level cannot be reached, the ProEFI will invoke a rev limiter to tell you that a problem is present as well as activate a check engine light. We have personally seen a handful of motors saved based solely on this feature. Rest assured that your engine is in the capable hands of the ProEFI.

Let's say that you have a pump that is tired and your fuel pressure is not rising 1-1 anymore. The computer will know and add necessary 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 a rev limiter. These safe guards can be triggered by the fuel pressure alone, by O2 activity or a number of other things!!

Multiple Failsafe Conditions
These built-in features make 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***8230;.

Flex Fuel E85 Compatibility
The ProEFI is the first standalone EMS to successfully adapt Flex Fuel capabilities in order to function like an OEM vehicle. Run pump gas, E85, or any mixture in between!! The ProEFI will always know exactly what percentage of ethanol is present in the gas tank and will make every adjustment accordingly to fuel maps, timing maps, and even cold start ignition!! We have started E85 powered cars in -2 degrees!!! Not only are these aspects controlled, but boost is as well. The ProEFI will only allow for the safest boost level based on ethanol content.

iBoost Control Integration
This is the best boost control system that we have ever used, hands down. Not only that, it's simpler than a manual boost controller!! There is absolutely no reason to even consider running an external boost controller, especially considering how inexpensive the solenoid and control knob is.

The iBoost system has the ability to utilize dual solenoids to control pressure to both the top and bottom ports on any wastegate. This will give you VERY accurate control!! With the addition of a CO2 canister, this means that you could have very minute control over the boost level and run as low of a pressure spring as possible. In addition, the ProEFI's Traction Control can lower boost levels substantially lower than if you were running a standard wastegate spring (such as 14-17psi). Imagine being able to bring boost levels down to 2psi with a light spring with the Traction Control. Will control boost based on traction control. Traction control is based on wheel speed differential described below. The ProEFI will also know what gear you are in by simply entering gear ratios from the service manual, rear end ratio and tire size!! It can also control boost by speed 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.

Scramble Boost
ProEFI has implemented a Scramble Boost feature to work in conjunction with its iBoost control system. For those not familiar, Scramble Boost is a feature that allows the user to temporarily increase their boost pressure setpoint for a pre-determined amount of time.

As we know, with the ProEFI iBoost system, there are 5 pre-determined boost settings from wastegate pressure to the highest desired boost level (based on ethanol content where applicable). When used in conjunction with the ProEFI Flex Fuel sensor, this highest boost level is limited by the ethanol content seen in the fuel tank. By adding a momentary switch, the ProEFI Scramble Boost feature will allow a boost increase (of whatever the desired level is) above your current boost setting for a predetermined length of time (be it 2 seconds to 20 seconds). For example, if you're on iBoost Stage 1 (which is wastegate pressure) and your spring is 14psi, you will now have a higher boost level such as 19psi (if scramble boost is set to +5psi) for a pre-determined amount of time (in seconds) before returning to the regular boost level. This feature is highly sought after among drag racers and road racers alike when that extra power is needed and there isn't enough time to change boost settings. This feature is also protected by the ethanol-content feedback meaning if you don't have enough ethanol percent present; the ProEFI will only allow you the safest amount of boost to maximize performance yet not exceed the limitations of pump gas (or your pump gas and ethanol mixture).

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.

Traction Control
Multiple comprehensive traction control strategies including defined wheel speed differential between driven and non-driven wheels. This is not your average traction control for the rain/snow!! This is a race-developed traction control system designed to keep your car going straight regardless of the conditions. There are a number of ways to control traction with the ProEFI, none of which will EVER pull fuel in an attempt to manage wheel speed. Reducing timing, dropping boost levels, and even a rev limiter can be used (in the extreme conditions) in order to maintain a consistent wheel speed differential. Road racing, drag racing, and especially street driving have all been proven to benefit from this system.

Advanced Knock Sensing Control Capabilities
Specific knock frequency detection based upon the specific engine being monitored makes for incredibly advanced engine protection!!

There are several ways to approach Knock control. Some manufacturers use more of a noise control than a knock control system. These systems use the knock sensor with a non-specific band pass filter to filter out some back ground frequencies. Then a user defined table is used to limit the amount of "noise" before it is considered to be knock. Once this threshold is reached action is taken by pulling timing and adding fuel in attempt to limit the noise. There are several problems with these types of systems. As the engine is producing more power, it also produces more noise, so if the noise isn't really knock, then power is greatly reduced for no reason. Using a broad band pass filter, you can't determine the frequency that knock actually occurs in the engine being monitored. Also by looking at the "noise" level, you don't know which cylinder is actually responsible for knock. It then gets even more complicated because you can't determine the window in which knock will occur in each cylinder. The systems that are monitoring noise rather than knock also lack the processing speed to properly determine what knock really is.

Nitrous control
Utilize up to 4 stages of nitrous control!! Nitrous can be controlled by speed, time, gear, and more! Just enter the number of jets, jet size and the ProEFI's Target A/F features do the rest!! It is recommended to add a nitrous bottle pressure sensor and the ProEFI adjusts accordingly to pressure!!

Unlike other ECU's, you can target different A/F's for Nitrous with this unit in closed loop, or open loop, since the computer is based solely 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!!!!

Nitrous Automatic Bottle Opener
With the engine running and the Nitrous system is armed, the ProEFI will automatically open your bottle!! This prevents accidentally leaving the bottle open and wasting nitrous as well as automatically closing the bottle in case of a system failure such as the motor stalling.

OEM Manufactured Quality
The ECU's are built by an O.E. manufacturer, so all ECUs are 100% tested for vibration, temperature, loading etc***8230;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.

20 Channel EGT Thermocouple Capability
Yes.....20 channel!! Put one in every runner, downpipe, or anywhere you can think of!! This is critical in tuning an engine to run exactly the same on every cylinder!!!

This is an awesome write-up from Induction Performance's tuner infamously known as "Alpha." I wanted to copy this over here. It's VERY informative!

I'm going to make this post pretty short as I am trying to catch up at the shop after being out at ProEFI's facility for three days and have a pretty busy week ahead of me.

I have had A LOT of people ask me what I think about ProEFI and about ProEFI in general over the last two to three years. I've told just about everyone I wouldn't comment on it due to not using it before I was able to, not using it enough as I didn't have the time yet. I don't recommend nor comment on anything I don't use and sell. ProEFI was no different. At this point I have a solid ten hours into the dealer software, end user software and installing the system in Supras. I will be using it with some other applications here soon.

First lets look at the hardware. Flat out ... It's solid. I'm sure more than a few of us have drop tested, toss tested and even fluid tested these with zero issues :rofl: The Pro128 uses a Freescale MPC 565 processor at 56mhz. The PRo48 uses a Motorola MPC 563 processor at 56mhz. The ECM is designed to meet automotive industry standard under hood environmental requirements for 12 volt and 24 volt systems, and also meets marine industry environmental requirements. Validation tests included extreme operating temperatures (-40° to +105° C), thermal shock, humidity, salt spray, salt fog, immersion, fluid resistance, mechanical shock, vibration, and EMC.

6.2 STORAGE TEMPERATURE: -40° to +125° C

6.3 OPERATING TEMPERATURE: -40° to +105° C

6.4 THERMAL SHOCK: -40° to +125° C transition within 10s for 500 cycles

6.5 FLUID RESISTANCE: Two stroke motor oil,

Four stroke motor oil,

Unleaded gasoline,

ASTM Reference 'C' fuel

6.6 HUMIDITY RESISTANCE: 85% humidity at 85°C for 1000 hours of operation

6.7 SALT FOG RESISTANCE: 1000 hours

6.8 IMMERSION: Submersible in 8% saltwater solution to 10'

6.9 MECAHANICAL SHOCK: 50 hours of 50 g's

6.10 DROP: Random drop tests on concrete from 6'

6.11 VIBRATION: Engine mountable and tested to high-performance levels


6.12 ABNORMAL SUPPLY VOLTAGE RESISTANCE:

Conditions Supply Voltage Time

Reverse Battery -24VDC 5 Minutes

Abnormal Alternator Output 36VDC 5 Minutes

Minimum Battery 6VDC Indef.

As you can see it's solid. From talking to Jason at ProEFI and Larry at SP there has been zero (0) failures.

Lets get into the software. The Dealer software is just that ... For the dealers. There is nothing fancy or pretty about it. It works and it works well. The End User software looks great, is easy to navigate and easy to use. If you can use other tuning software/editors, Quick Books, Microsoft Live or any other easy to use program you can use the End User software.

Support. You have the support of the dealer you purchased the ProEFI from. Even away from your dealer other dealers are willing to help end users of ProEFI out as well.

In short ... ProEFI gets my full support :bigok: If you have any questions feel free to ask. If I am not able to answer it I am sure Larry from SP or Chris from SS will. Some pictures below from my recent trip to ProEFI's facility in Arizona.


























Jason from ProEFI and Larry from SP testing trunk space :lol:

So aside from the obvious, for those of us with the current HPF fuel system, what else (fuel wise) would we need to buy in order to be full E85 compliant?

I know of only one fuel kit so far that is out there, which is what Marcus just had installed, the Saad racing fuel kit. Adding the cost of ProEfi + new fuel kit, is getting a bit expensive, almost as much as jumping up to the next stage. So far I don't see many of the AEM being picked up quickly by others, so that would be a lost investment on it's own.

We need an option of making our current fuel system E85 compliant, but not completely getting rid of it all, if that is even an option.

Unfortunately there isn't really any parts that are salvagable going from gas to E85 with the kit you have. You need Teflon lines and steel fittings if you want a carefree fuel system for the long haul. The pump capacity isn't near enough for E85 (depending on your power level). The best thing to do is to pull the system and sell it to someone complete who isn't going with E85, and replace it with a Larger capacity system that will handle any of your future needs.
