Do you use the EM2 for eng. info.? Look at your graphing page for controller A and make sure the fuel map didn't go all lean. I had a problem with a 13B EC2 internal chip that would corrupt the fuel map after aprox. 40 to 50 minuets of flight and eng. would not stop but ran VERY poorly, switch to B and it ran ok to land, some settings would go full lean and others would remain in center. If yours corrupted ALL settings then eng. could not run (it would be full lean in across full map). I think I have an EC2 for Ren. I am moving so not sue where the box is.                                       David R. Cook RV6A  Rotary Charlotte MI.
