TUV certificate - something about electromagnetic compatibility with car electronics, i'm not sure, it is in Czech language
i will try to translate
unit for direct injection works good with most of FSI TSI TFSI engines (now i have about 35 positive tests), and with Mazda direct injection system, but on some engines sometimes CE light turns on.
now i must made some changes into linearity of enrichment and range of enrichment coefficients, test again, and i think everything will be ready.
not much time for it - i must produce main unit, and testers located in other countries, in Ukraine we still have no E85 (but a lot of E40, on many fuel stations).
in this version enrichment value and enrichment time depends from temperature (measured by sensor)
lower temperature - higher enrichment, longer enrichment time.
two rapms = two fuel rails?
you can cut main cable isolation, and separate all wires to 2 different cords.
it is useful for installation to subaru engines, for example
