Hello Everyone I need some assistance. I just replaced my F20C with an F22C since I dropped a valve and I cannot get my car to stay on. I am using AEM EMS with a turbo setup. I start the vehicle with normal cranking, it fires up and sounds normal and then it abruptly shuts off. Sometimes it stays on for several seconds and sometimes it shuts off immediately after cranking. I have a wideband installed and it does not look like it is leaning out, it seems more like ignition is not working properly. Anyone have any ideas?

Here is a video of one of the times it stayed on for a longer period of time:

 

Who is your tuner? Has he looked at the logs in the EMS?
