I drive a Corsa B, built in 99 with a 1.0L three-cylinder engine. I would like to upgrade it to E85pur, with the option still normal E10 to be able to refuel. When scouring the WWW, I read more that the ECUs offered at Ebay for 90€ should not work really well. These are only attached to the injectors… I have now discovered the Flexitune AutoX4 and wanted to ask here if anyone can tell me if the vehicle is compatible. guess is good and if it is suitable for my car. In addition, I have the question, how this works with the wire harness. Can I buy this somewhere? Is the installation difficult? And is my car even adaptable to E85? Thank you in advance.
