My LGT is back on the road.
installed the iBR flex01 kit New flexfuel controller and wiring harness Install was super simple and ethanol readings are identical to what I was seeing prior to the Cobb hardware failure
im not sure what caused the issue but the Cobb harness fried itself and melted the wiring from rear o2 12v input to the controller.
ibuildracecars.com makes a very slick replacement controller and harness Their unit does not pull 12v from o2, instead it draws from the TGV +5v to power the ethanol sensor I just wish it came in blue or black. The company is based in Pittsburgh, which makes me proud to support a local enthusiast
