The advantage of our ethanol box is that it allows you to completely forget about the super unleaded 95/98 if you wish and without the fault indicator light on the dashboard.

How do our Starflex boxes work? How does the engine detect and adjust its injection according to the quantity of ethanol? Why is the ethanol sensor useless? Watch this explanatory video

In most cases we send you the bioethanol kit fully ready to be installed, with the injector connectors corresponding to those of your engine, the connectors are plugged in so that you do not have to look for the polarity (except in certain cases where it may vary for the same model), and the ethanol unit will be preset for your engine, which will greatly simplify the assembly since you will only have to plug it in and drive it.

For some engines, we have designed specific bioethanol kits for quick and easy installation because the connection is made to the general socket connecting all the injectors as in the image below, so you save a lot of time during assembly and discretion. unparalleled installation.

This installation technique allows simple, quick assembly or disassembly without any real need for mechanical knowledge.

How do our E85 boxes work?

Our ethanol kit is installed on the injectors which will derive the signal from the computer sent to the injectors to the ethanol kit which will send it back instantly modified, thus the ecu computer not being aware of the presence of the ethanol kit, will take into account this modification and adapt its injection corrections, also called “fuel trim”, accordingly. This modification will allow your ECU not to reach its maximum tolerance which usually causes the engine failure warning light to come on on the dashboard caused by an air/fuel mixture that is too lean. You should know that your computer is designed to continuously modify its injection corrections by increasing or decreasing them as follows:

  • fuel quality 
  • The density of the air which varies according to the altitude and the temperature
  • The state of wear of certain engine parts such as the air filter, fuel pump flow, injectors and others

But its correction capacities are not sufficient to support E85 superethanol, for this reason the installation of our E85 box will allow your engine to never be too lean on ethanol and too rich on unleaded, like us. let's explain it in the video above.

Beware of influencers on youtube and others who want you to believe that an ethanol sensor is essential for proper operation, this is wrong and we explain it very well in the video above. It is often to promote a product, and as proof, these boxes with E85 sensors do not even represent 0.01% of converted vehicles and for as much you are millions to circulate with E85 boxes or reprogrammed ECU without ethanol sensor and it works very good since it's useless. They claim that the lambda probe does not transcribe a coherent ratio while they will use the information from this lambda probe to make a good adjustment of their housing with bioethanol sensor. On the other hand, with or without an ethanol sensor, it is necessary to avoid boxes that do not offer adjustment possibilities because, depending on the flow capacities of the injectors and depending on the engine models, the setting of the box may be different.
