Installation instructions for the 2.0 Wifi box

1a / Setting the additional fixed injection rate (1a) if you do not have the ethanol sensor

In principle you do not need to modify as we send you the box with a preset that is suitable for your engine, however you can fine-tune the setting if necessary. Any modification must be made with a basis of comparison which must be identical, i.e.: Engine hot > 60°C Engine idling Headlights, air conditioning, ventilation and other accessories must be turned off.

• Detail of dial 1:
• – Case serial numbers
• – % fixed additional injection sent by the unit if the ethanol sensor option is not validated or if the ethanol sensor is not connected
• – Base of % of maximum additional injection for 100% of ethanol (E100), when the ethanol sensor option is validated and the sensor is connected the box will modify this base of 100% according to the % indicated by the ethanol sensor.

First method (the simplest):
After having carried out all the checks before installation as mentioned at the beginning of the instructions, carry out these operations:
– Switch on the vehicle’s ignition
– Once connected to the box's wifi network (in rare cases starting the engine may be necessary to connect), start the PC interface, then go to the settings page.
– Set % (1a) to 0%
– Save and exit (11) by inserting the password. You should receive a “Password Validated” confirmation
– If the engine was started, let it idle for 2 minutes, otherwise start the engine and let it reach at least 60° and cut off all current consumption (air conditioning, headlights and others, etc.)
– Go to the “Parameter display” page and note the average injection time sent by the ECU when the engine is idling (15a) by taking a screenshot for example.
– Go to the settings page
– Switch % (1a) to 20%
– Save and exit (11) by inserting the password. You should receive a “Password Validated” confirmation
– Go to the “Settings display” page

• With the engine idling, check that the average injection time sent by the ECU (15a) has decreased by 20%. This modification is more or less rapid depending on the ECUs and the state of your lambda sensor before the catalytic converter.
  
  With the engine idling, check that the average injection time sent by the ECU + box (15b) is approximately similar to the value (15a) that you noted when the % (1a) was on 0%
• Check in the desired fixed additional injection % corresponds (15d) to what you have validated
  

Second method:
Requires OBD scanner to be connected.
Show LTFT1 (Long Term Fuel Trim) and STFT1 (Short Term Fuel Trim) injection corrections for an in-line engine.
If V cylinders you also need LTFT2 and STFT2.

Using the OBD scanner, modify the additional injection fixed % sent by the box (1a) in order to modify the injection corrections so that the addition of the short-term and long-term corrections is close to -20%.
However, these checks require some knowledge of the operation of the different computers because the data can have different coefficients and slow regulation, not to mention the ECUs which display the STFT or LTFT in reverse values, all this can mislead you if you do not You're not used to doing these checks, which is why we have developed a PC and smartphone interface which will considerably simplify your checks and adjustments.
These are the short-term corrections which will evolve initially then the long term will modify to bring the short term back to an oscillation close to 0.
The long-term evolution time may take more or less time depending on the ECU, the ideal is to drive for 2 fill-ups of E85 and recheck the long-term corrections.

When checking at E85 the LTFTs must be between 0% and +10% and the STFTs between 0% and 5% (provided that the max and min values are -25% / +25%)
How to know the maximum and minimum values of the LTFT and STFT injection corrections

1b / Base setting of % maximum additional injection for 100% ethanol (E100) with ethanol sensor

In principle you do not need to modify because we send you the box with a presetting that is suitable for your engine, however you can fine-tune the setting if you wish. Any modification must be made with a basis of comparison which must be identical, i.e.: - Engine hot > 60°C - Engine idling - Headlights, air conditioning, ventilation and other accessories must be turned off.

• Detail of dial 1:
• – Case serial numbers
• – % fixed additional injection sent by the unit if the ethanol sensor option is not validated or if the ethanol sensor is not connected
• – Base of % of maximum additional injection for 100% of ethanol (E100), when the ethanol sensor option is validated and the sensor is connected the box will modify this base of 100% according to the % indicated by the ethanol sensor.

First method (without OBD scanner)

After having carried out all the checks before installation as mentioned at the beginning of the instructions, carry out these operations:
– Unplug the ethanol sensor
– Switch on the vehicle’s ignition
– Once connected to the box's wifi network (in rare cases starting the engine may be necessary to connect), start the PC interface, then go to the settings page.
– Set % (1a) to 0%
– Save and exit (11) by inserting the password. You should receive a “Password Validated” confirmation
For display (1b) leave our basic settings of % maximum additional injection at first.
– If the engine was started, let it idle for 2 minutes, otherwise start the engine and let it reach at least 60° and cut off all current consumption (air conditioning, headlights and others, etc.)
– Go to the “Parameter display” page and note the average injection time sent by the ECU when the engine is idling (15a) by taking a screenshot for example.
– Turn off the engine and reconnect the ethanol sensor
Important: These first information measurements must be carried out with super unleaded 95 or 98 only otherwise you will have a difference when the ethanol sensor is reconnected.
– Put the % (1a) back on 20%
– Save and exit (11) by inserting the password. You should receive a “Password Validated” confirmation
– When you have filled up 2 times with E85, check or ask your customer to send you a screenshot (24c) on their smartphone application (having remembered to do it at idle, hot engine, air conditioning, ventilation, headlights, car radio or other turned off), all you have to do is compare the ECU injection times with those that you had memorized in the super unleaded car, these values should be practically identical (approximately between -5%/+5% difference) . Take into consideration that the box provides you with injection times with a precision of 1/100,000th of a second so a small deviation is not very important.

If necessary, ask your customer to come back to adjust the % (1b), this will be quick since you will not need to open the cover to make this adjustment.

Second method: with the OBD scanner :
Proceed as for method 1 except that you note the LTFT + STFT values before installation with super unleaded fuel, then you will have to bring the customer back after 2 fill-ups with E85 to connect the OBD scanner and check that the LTFT + STFT are similar and if need modify the % (1b)

For each temperature threshold you can adjust the additional % injection sent by the box.

• – The yellow column corresponds to the desired operating time (max 120 sec)
• – The orange column corresponds to the % enrichment of the additional % sent by the box, the injection time sent by the ECU is not taken into account in this % (min 100% / max 500%)

Example: If in normal operation your box adds an additional % of 20%, the cold start if it is at 100% will remain the same, it will be X2 at 200%, X3 at 300%…

In operation, the triggering and the % can be checked on the Parameter display page

Very important, for these modifications to be effective you will also have to click on save and exit (11) on the settings and options page and insert the password to validate the settings which was given to you when you ordered. Without this final validation there will be no change.

Checking operation:

Please note, the operating time starts when the box is powered on, so if for example you turn on the ignition without starting for 120 seconds the cold start time will have expired.
Also take into consideration in the event of several cold starts in a short period of time, be aware that some ECUs cut off the voltage on the injectors a few minutes after switching off the ignition, this is verifiable with the wifi shutdown delay given that It is powered by the voltage present on the injectors.

When cold start is activated, the red light turns green on the Parameter display page and on the application (yellow frame)

Setting:

• – Setting the operating time from 0 to 25 minutes [4a]
• – Setting the maximum operating temperature [4b]. Above this temperature you will need to check the Ignore button on the parameter verification page to switch to forced operation.
• – Setting the minimum necessary battery voltage [4c]. Below this voltage you will need to check the Ignore button on the parameter verification page to switch to forced operation.

Operation stops when you operate the starter

Very important, for these modifications to be effective you will also have to click on save and exit (11) on the settings and options page and insert the password to validate the settings which was given to you when you ordered. Without this final validation there will be no change.

Turning on the rail heater

2 possibilities for triggering: on the PC software or on the smartphone application

It is necessary to turn on the vehicle's ignition to activate this operation.

On PC software

• – Switch on the vehicle
• – Connect the PC to the ParadigmE85 wifi network
• – Start the ParadigmE85 2.0 software, then go to the Parameter Display page

If the battery voltage information and the maximum T° are lit in green, all you have to do is click on the large trigger button to turn on the injection rail heater.

The light below turns green indicating that the heater is triggered.

The display and operation is identical on the smartphone application

When you want to start:
– Turn off the vehicle’s ignition
– Wait until the wifi network disappears.
– Start the engine

This operation will cease in the following cases:

• – At the end of the time recorded in the settings
• – If you operate the starter

As a security measure, this triggering only takes place once, if you wish to repeat this triggering, you will need:

• Turn off vehicle ignition
• Wait until the wifi network disappears then repeat the triggering procedure.

___________________________________________

Forced walk:
If the battery voltage or temperature does not allow the heater to be triggered, you have the option of triggering it in forced operation.

Warning: If your battery voltage is too low, forced operation may cause you to no longer have enough battery to operate the starter.
For this we strongly recommend triggering it on the sole condition that you have a starting booster or another vehicle running to which you can connect the battery cables.

To trigger forced operation:

• – Switch on the vehicle’s ignition
• – Validate the Ignore button, a warning message will be displayed
• – Press the trigger
• – Check if the trigger indicator light has turned green.

If the indicator light does not light up, there are several possibilities:
– Error during assembly
– You waited too long with the vehicle ignition on.
In this case :

• Turn off vehicle ignition
• Wait until the wifi network disappears then repeat the triggering procedure.

OBD scanner is required for checking settings

Treats:
Once the connections are made:

• – Disconnect the IAT probe
• – Connect the OBD scanner to the vehicle’s diagnostic socket
• – Switch on the vehicle’s ignition
• – Check on your OBD scanner, normally the IAT temperature information should flash and display the minimum temperature supported by the ECU which varies depending on the brand (eg: -40°C on certain Peugeot/Citroën, -18° C on certain FIATs, etc.)
  This allows you to know the minimum temperature that should not be reached so that the ECU does not display an engine fault.
• - Cut contact
• – Reconnect the connector to the IAT probe
• – Switch on the ignition and clear the fault recorded by the ECU
• – Turn off the ignition for 10 seconds to confirm that the engine fault has been cleared
• – Switch on the vehicle’s ignition
• – Connect the PC to the ParadigmE85 wifi network
• – Open the PARADIGME85 software and go to the settings page
• – You have 5 adjustment positions which go from 0 (no modification) to 4 (maximum modification)
• – Modify the position of the function continuously [5a(f)] so as to know the coldest position without reaching the minimum tolerance that you checked previously. Still leave a margin of 10°C with the minimum tolerance.

So you know the maximum adjustment position (which is between 0 and 4) not to exceed

Now modify the setting and subsequently modify the positions for each temperature level if necessary.

Take into consideration that positions 5a(a) / 5a(b) / 5a(c) / 5a(d) / 5a(e) will operate for 180 seconds from the moment you switch on the vehicle's ignition.

Temporary changes 5a(a) / 5a(b) / 5a(c) / 5a(d) / 5a(e) are ideal if your box is also connected to the injectors, this improves cold starting

Continuous modification will be used if the box is not connected to the injectors because it allows the ECU to work on maps with slightly richer injection corrections.

The setting on the continuous function 5a(f) remains master (if Position 5a(f) ≠ 0) on the positions of the temporary functions 5a(abcde)

Very important, for these modifications to be effective you will also have to click on save and exit (11) on the settings and options page and insert the password to validate the settings which was given to you when you ordered. Without this final validation there will be no change.

Checking operation:

• The OBD scanner can check if the temperature is changed.
• On the PC software, go to the Parameter display page
  • – The green light indicates if the option is activated, otherwise it is red [17a(a)]
  • – The current position is displayed [17a(b)]

Checking the status of T1 and T3 modifications (dial 26a and 26c)

Changing IAT Air Intake Temperature (T3):
Some engines are equipped with 2 IAT probes, in this case the procedure for the 2nd IAT probe (T3) will be the same as for (T1)

OBD scanner is required for checking settings

Treats:
Once the connections are made:

• – Connect the OBD scanner to the vehicle’s diagnostic socket
• – Switch on the vehicle’s ignition
• – check the injection rail pressure with your OBD scanner
• – Connect the PC to the ParadigmE85 wifi network
• – Open the PARADIGME85 software and go to the settings page
• – Modify the positions [7a] if the installation does not include the ethanol sensor option. (ex: 10%)
• – Remember to validate the setting changes by clicking on Save and exit (11), then inserting – the password which was sent to you when you ordered this option. A message indicates – that the password is correct and that the setting is applied, then the page will close to take these changes into account.

Checking operation:

• – Check with the OBD scanner if the HP rail pressure has changed
• – Also check on the Software Parameters Display page:
  – The green light which tells you if the option is activated, otherwise it lights up red [20a(a)].
  – The desired modification % [20a(b)]
  – The received voltage [20a(c)]
  – The emitted voltage [20a(d)]

Be careful, depending on the ECU, too much modification % can illuminate the engine fault light on the dashboard, in this case it will be necessary to reduce the % [20a(b)]

Checking the status of modifications C1 and C2

• Checking on the PC interface: you can see if the option is activated as well as the voltages received and transmitted

• Checking on the smartphone application: you can see if the option is activated as well as the voltages received and emitted

• Verification with the OBD scanner, when the changes are validated by password you will see the ramp pressure change

The procedure is the same as without an ethanol sensor explained in the previous chapter (7a/1 above) with 1 difference:
The box will apply the modifications only when the ethanol sensor informs a % greater than 30 %.

Same as 7a/2 above

Same as 7a/1 above

Settings with PARADIGME85 2.0 software:

ECO mode:

• – Switch on the vehicle’s ignition
• – Connect the PC to the ParadigmE85 wifi network
• – Open the PARADIGME85 software and go to the settings page

Settings:

• Go on a trial
• Check on the Parameter display page or the duty cycles page on the application [24a] and check the DUTY CYCLE [15c] by proceeding as follows:
  – Accelerate fully to the red zone in each gearbox from 3rd and above
  The goal is not to reach the 100 % of Duty Cycle otherwise it means that your injectors no longer have time to close.
  Leave a margin of approximately 10 % or 90 % of Duty Cycle maximum

Adjust the setting if necessary and repeat this procedure each time you change it.

Don't forget to save by inserting the password so that the modifications are validated.

You can also check on the PC interface and the smartphone application the additional % sent to the injectors which is changing and modify your adjustment from 0 to 25 position according to the desired values.

Operation check :

• – On the PARADIGME85 2.0 software, open the parameters display page.
• The indicator [19a] lights up green when SPORT mode is triggered

• – On the PARADIGME85 2.0 application, open the parameters display page.
• The indicator in the yellow frame lights up green when SPORT mode is triggered
  – On the mode modification page, the current mode always has the gray “Save” button, otherwise it is green.
