V4.10.2 firmware was the last firmware update ~2014. ManuStock 1 Quote Link to comment Share on other sites More sharing options...
ManuStock Posted February 7 Author Report Share Posted February 7 Thanks for reply! Its posible add e85 sensor in that ecu? Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 7 Report Share Posted February 7 Yes you can use a common seimens or continental ethanol sensor to receive ethanol content and temperature into the ecu, however there is no true flex fuel functionality in these older ecu's. You can use 4D tables to vary fuel and ign with ethanol content as well as stuff like boost, but there will be compromises for some functions like cold start etc. Quote Link to comment Share on other sites More sharing options...
