Operation of the specific Starflex box:
For certain engines which allow it we offer specific boxes which offer the same functioning except that rather than connecting to the injectors our harness connects to the general socket which connects all your injectors. So you gain in aesthetics since the connection is much less visible, and especially in labor time because it takes only a few minutes to install it.
Automatic operation: The electronic computer of your car has the possibility of decreasing or increasing the injection times sent to the injectors but with a maximum and minimum tolerance which are suitable for operation with unleaded super.
The problem is that if we put ethanol without a casing, the lambda probe will indicate to the electronic computer that the air / petrol mixture that comes out of the exhaust is too lean, the computer will increase its injection times but it will reach quickly its maximum tolerance and will eventually go into degraded mode and turn on the “fault fault” indicator on the dashboard because of a too lean mixture.
Our ethanol box will provide additional injection time to the injectors which will allow the electronic computer of your engine to correctly correct its injection without ever reaching its maximum tolerance for which it has been programmed, this will allow it to function as usual .
And conversely if we give back unleaded super, for example by increasing the injection time of 15% via the ethanol box and the lambda probe will indicate to the computer a rich mixture and the latter will reduce its injection times by 15% compared to its usual lead-free operation without reaching its minimum tolerance and can therefore compensate for the enrichment of the ethanol unit in order to provide an optimal mixture (ratio).
In this way, your engine will function optimally, regardless of the ethanol and / or lead-free mixture present in the tank.
Info : It is your exhaust regulator probe (lambda probe) which regulates the carburetion thanks to an oscillation which allows the engine ECU to know if what comes out of the exhaust is too rich or poor and will correct its injection times Consequently.
Cold start: a temperature probe is integrated into the box, and according to a set of parameters (outside temperature, last start, last operating time, etc.) the box will modify the choke accordingly.
The advantages of the specific Starflex housing
Sent with the connectors connected and the preset box for your motor, so your assembly will be significantly simplified and will be done in a few minutes.
No illuminated fault indicator on the dashboard.
Works as well with super unleaded as with superethanol E85 or whatever the mixture of the two.
No need to add unleaded Super in winter to start
It is no longer necessary to put Unleaded Super unless you wish
Once installed, you can directly fill up with E85 without going through several stages (25% the first, then 50% the second, etc…)
Optimal operation up to 10500 rpm
Interchangeable beams: in case you change vehicles, only the beam will have to be changed.
Circuit board protected from humidity thanks to a protective resin
Made in France
