mellonman Posted October 18, 2011 Share Posted October 18, 2011 sorry for the maybe dumb question this bit is all new to me, but would a single turbo be mapped to have a closed loop, or are they always in open loop. Quote Link to comment Share on other sites More sharing options...
johnny g Posted October 18, 2011 Share Posted October 18, 2011 It'd be open loop on-boost and closed loop (to lambda) off boost. Quote Link to comment Share on other sites More sharing options...
mellonman Posted October 18, 2011 Author Share Posted October 18, 2011 so a wide band is fine for stand alone but you would need stock for o2 for piggyback. Quote Link to comment Share on other sites More sharing options...
johnny g Posted October 18, 2011 Share Posted October 18, 2011 Most widebands can also simulate a stock o2 (narrow band) sensor Quote Link to comment Share on other sites More sharing options...

bignum Posted October 18, 2011 Share Posted October 18, 2011 My ecu doesn`t see any lambda sensors Quote Link to comment Share on other sites More sharing options...
mellonman Posted October 18, 2011 Author Share Posted October 18, 2011 My ecu doesn`t see any lambda sensors so you run open loop? i think it just means you will run richer when on part throttle i think lol Quote Link to comment Share on other sites More sharing options...
