subtle_driver Posted December 22, 2013 Share Posted December 22, 2013 My stock l28et runs lean (higher than 16:1 afr) at cold start-up. It should be rich for a little bit. I have to run the engine for a couple min before it goes into closed loop and runs perfect and in specs. The block temp sensor is within specs. What does this fuel management read from and do for the first couple minutes of cold startup? Thanks! Quote Link to comment Share on other sites More sharing options...
mattb3562 Posted December 25, 2013 Share Posted December 25, 2013 Are you getting a 5 sec prime with key "on"? Quote Link to comment Share on other sites More sharing options...
