Box-E85.com

This is unprecedented and essential, because as you know ethanol boxes and reprogramming have an increasingly bad reputation, even some professional installers stop the transformations due to the fact that there is a serious lack of information and troubleshooting capacity in the event of engine malfunction, it is often necessary to remove the box or reprogram at the origin due to lack of solutions and information.
With the new 2.0 box this problem is solved because you have maximum information on each cylinder which is unprecedented

• – Duty cycle (% opening of the injectors, if you reach 100% it is because they no longer have time to close and remain constantly open)
  – Injection times sent by the electronic engine computer (ECU) to 1/100,000th of a second
  – Injection times modified by the 2.0 box (ECU + Box) to 1/100,000th of a second
  – % additional injection created by the housing

Since 2015 we have been the creators of this connection method.
For simple, quick and discreet assembly, what could be better than plugging into the socket which connects all the injectors, so when the injectors are difficult to access and this general socket is present, the assembly will be very simple and you will save time on workforce.
Currently we offer specific quick-fit harnesses for brands like Alfa Romeo, Audi, Chevrolet, Chrysler, Citroën, Daewoo, Fiat, Ford, Hummer, Infiniti, Jaguar, Jeep, Lada, Lancia, Land Rover, Lexus, Nissan, Opel, Peugeot, Renault, Seat, Skoda, Toyota, Volkswagen.

Recommended for those who live in very cold regions, such as Scandinavian countries, Canada and others, this method allows you to trigger a heating strip to attach to the injection rail in order to improve your cold start without the need to add super lead-free.

If you carry out the order and assembly yourself, no problem you will know the password to validate your changes to the settings, but if you are a professional and you do not want your customer to be able to change your settings in this case you order the box with the professional discount (if you are registered) and you keep the password so that only you can make a modification. The smartphone application transmits all operating information but does not allow changes to settings to be made.
So, no unpleasant surprises or annoyance following a modification made by the customer or another curious mechanic.

Please note we are talking about settings because otherwise the OBD scanner is necessary to carry out the essential checks before installing the box

Important: any adjustment or adjustment verification must always be carried out in the same way, otherwise the values may vary and mislead you:
– Engine idling
– Hot engine (>60°C)
– Headlights, air conditioning, car radio, ventilation and other power consumers turned off.

It is even more precise than with an OBD because some ECUs carry out their modification but do not display it instantly on the OBD scanner, it is sometimes even quite long to perceive.

• – With the ethanol sensor what could be simpler: given that you have all the operating information on each cylinder, once assembly has been carried out and the vehicle is still unleaded, you note or make a screenshot of the times ECU injection times at idle, then once you have done 2 or 3 fill-ups with E85 you check the ECU injection times which should be practically similar (+/- 5%)
  – Without an ethanol sensor it is also very simple, given that you have all the operating information on each cylinder, once assembly is carried out and the vehicle is still unleaded, before starting you set the “Additional rate” setting fixed injection rate if probe absent” to 0, you validate with your password, you start, you note or make a screenshot of the ECU injection times at idle, then you modify the “Rate” setting again additional fixed injection if probe absent” on 20, then once you have done 2 or 3 fill-ups with E85 you check the ECU injection times which should be practically similar (+/- 7%)

And if your E85 injection times are very far from these tolerance values, there is a problem, in this case too it is very simple:
– Check that the box is working: set the settings mentioned above to 0, validate with the password,

• – You should hear a reaction from the engine as the extra injection is removed
  – Then check in “parameter display” that the additional injection % is on 0 (+/- 1%).

If you do not notice any difference, the box may possibly be defective, otherwise the problem does not come from there, in this case our page "Trouble shooting" can help you

More stable and faster, we preferred to opt for wifi communication for our PC interface and smartphone applications

Very practical for professionals, thanks to all the information present on the smartphone application, in the event of an engine malfunction, the customer will be able to without problem send you screenshots in order to detect with you remotely whether it concerns the injection or No. This will allow you to gain the trust of your customer but also to avoid unnecessary costs from an unscrupulous mechanic if he is far from you.

1/ When the engine runs constantly with 1 cylinder less:

• – Remove the engine fault with your OBD scanner
• – When you start, if it is an ignition problem, the cursor of the cylinder concerned (on the interface or application) which presents a malfunction will remain frozen for 3 seconds following starting.
• When you start, if it is an injector or injector harness problem, the cursor will freeze about 10 seconds after starting.

This fault finding accuracy cannot be verified with an OBD scanner, which is why our new box presents a great technological advance. Diagnoses of combustion problems have never been so precise and detailed.

This is easily verifiable as well as the cylinder concerned on the smartphone interface or the PC interface because the operating values of the cylinder concerned remain fixed, moreover the color of the cursor which displays the malfunction will allow you to find the cylinder concerned without problem because you will only have to find the injector which has the connection wires of the same color as the cursor (blue, gray, green or brown). It saves time and is a considerable help, even essential when troubleshooting.

2/ If the engine malfunctions intermittently

Take a test with the smartphone or PC connected to the box and check on the page displaying the injection times, the cursor which moves abnormally when the engine malfunctions, you will then be able to easily identify the cylinder concerned thanks to the color of the cursor which is the same as the color of the wires in our harness (blue, gray, green or brown)

• – If all the cursors move abnormally during the malfunction: Ignition problem, therefore spark plugs, coils or ignition harness
• – If 1 cursor moves abnormally during the malfunction: Ignition problem therefore coil and/or spark plug, or poor connection on the male socket of the connector of our harness
• – If no cursor moves abnormally during the malfunction: Injector problem or poor connection on the female socket of the connector of our harness connecting to the injector or problem with connection of the red wire on the male or female connectors of our harness

Important: any adjustment or adjustment verification must always be carried out in the same way, otherwise the values may vary and mislead you:
– Engine idling
– Hot engine (>60°C)
– Headlights, air conditioning, car radio, ventilation and other power consumers turned off.

If you are a professional installer for example, there is no need to ask your customer to come back in 2 weeks to check the settings, you will only have to ask them to comply with the conditions above and to send you one or more screenshots of ECU times using its application, and if necessary to make a modification, no need to open the hood thanks to wifi communication.
You can even change your settings instantly with the engine running.

ECO / SPORT mode, only offered with the ethanol sensor option, allows you to choose from 3 positions:

• – ECO: the box on certain sequences will slightly modify its operation to adapt to eco-friendly driving.
  – NORMAL: No particular modification depending on behavior
  – SPORT: The box on certain sequences will modify its injection (adjustable) to make your engine a little more responsive

In addition to the numerous specific harnesses, we offer a range of 11 different injector connectors while our colleagues generally only offer 6.

Thanks to our powerful interface and smartphone application, you have the advantage of seeing the operation on each cylinder/injector.
As you can see, each cylinder display has a color that you can find on the wires of our harness.
So, if on our interface or application you detect a malfunction on cylinder 1 which is blue in color, you will only have to find the injector which is connected with the blue and white/blue colored wires in order to easily start your research and verifications.
It's a considerable time saver and very practical.

Optional ? For what ?
Let's be honest, if your engine is equipped with a lambda sensor before the catalytic converter, which is the case on all cars from 2000, the ethanol sensor will always have a secondary operating role and is therefore not really necessary.
No offense to our colleagues who market boxes with an ethanol sensor and who try to make people believe that it is essential for flex fuel operation...this is false. The electronic computer is fully designed to increase or decrease its injection times depending on needs, and only the lambda sensor before the catalyst has a primary role, it is this and this alone which ultimately adjusts the air/fuel mixture so that it is optimal. Those who really know motor electronics know this.
As proof, an old, slightly faulty ethanol sensor sending information shifted by 20% will not cause a malfunction because the ECU will correct this failure using information from the lambda probe. The opposite is not possible, the engine will run poorly and the ethanol sensor can never adjust this.

On the other hand, it allows quick and simple adjustment because the ECU retains its entire injection correction range.

On the other hand, the ethanol sensor is essential for engines without lambda probe and which therefore do not have injection correction, such as old injection, certain motorcycles, quads, buggies, boats.

This option, in the case where the box is not connected to the injectors, allows for a better cold start and to gain approximately 7% of injection correction, which can sometimes be sufficient for E85 for certain engines.

This option, in the case where the box is not connected to the injectors, allows the pressure information in the injection rail to be slightly modified to cause an increase in pressure and gain injection correction. This can be an alternative on direct injections if our box does not work when connected to the injectors.

Whether your engine has 1 to 8 injectors, the housing is the same, so you will be able to reinstall it on a wide range of engines

Our box works on several direct injection engines, however we have not yet been able to try all the engines, this is why we have not yet opened its marketing for this type of engine.
