Hello interested parties of the Honda Civic Hybrid, ride since approx. 5Mt. a 2007 Civic Hybrid with a Flex Fuel controller of the latest controller generation developed in Germany with 16bit processor. For information see http://www.bioethanol-control.de. Conversion costs EUR 699.- I can drive with E85 and have the first Flex Fuel Honda Civic Hybrid in Switzerland. In Switzerland this is also very useful from an ecological point of view, since the offered E85 exclusively from domestic waste So no fuel that indirectly increases the food prices, as is often falsely claimed. More consumption is about 15% compared to Super. (approx. 6.5L to 5.5L/100km in normal everyday driving without extremely saving) when operating with E85. This is normal because the calorific value of e85 is about 30% lower than compared to petrol. My experience is very positive, except that it goes on from time to time with the engine control lights and spits into the fault memory mixture to lean. A new software version is intended to fix this error, which results in the short time the mixture becomes too thin (a few fractions of a second, which is absolutely safe for the engine and cat) and the Honda PGMFI system interpenetrates this as an error. In Germany the current price of E85 EUR 0.97 in Switzerland is approx. EUR 0.9. In France even EUR 0.8. One in comparison to autogas in every more economical matter without expensive tank conversion. n Honda Civic of the yes standard a C02 output of only 109g/km now approx. 30G/km.
