Description
Modifying the intake air temperature coupled with a modification of the fuel rail pressure can be an alternative to connecting to the injectors for direct injection.
Our 2.0 Wifi box works on many direct injection engines, but on some engines the ECU may detect the modification made to the injectors; in this case, you have the option to modify the values emitted by the IAT and HPS probes to obtain the necessary enrichment when switching to E85.
Important: only works on IAT temperature probes with 2 wires (2-pin connector)
For indirect injection engines, modifying the intake air temperature provides better cold starting and an additional enrichment range so that the ECU does not reach its maximum E85 injection correction tolerance; however, our 2.0 Wifi box offers such extensive adjustment possibilities for operation and cold starting when connected to the injectors that this option remains optional.
– The unit offers 5 adjustment positions ranging from 0 to 4. Depending on the ECU, an adjustment position that is too high may cause an engine fault, so it will be necessary to find the correct setting as explained in the assembly and adjustment instructions.
– 2 Operating possibilities:
– Momentary: duration 3 min at startup
- Permanent
– Possibility of modifying 2 intake air temperature sensors provided that options T1 and T3 are activated.
The setting can only be adjusted on the PC application.
Functionality and parameter checks are performed on the PC and Smartphone application.
Important: as we have not been able to test this operation on all existing engines, we are therefore unable to guarantee that this type of modification is suitable for your engine, but we have not encountered any malfunctions so far.
