    E67 2.4L supercharged

    Hi guys,

    Any way I can ask for something richer than 14.7 in closed loop ? Did not find anything yet with the tables. Car is supercharged and does not like running 14.7 idling and under vaccum.

    Thanks,Attachment 86960

    Do you want to command a lower stoich afr at idle only or all the time? because in closed loop your ecm will always request the calibrated stoich value and maintain that afr which for you is set at 14.7 to which you can change but it will always command that if thats what your looking to do - that chart is found in engine/fuel/general/stoich afr - the only way to command a different afr at idle vs cruising would to be in open loop to where you can tune it that way because like i said in closed loop the ecm will always request the calibrated stoich value

    Most fuels have E10 in them now, you could try 14.10 like all the new cars do.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Thanks !

    I can be a little bit richer everywhere to be honest the engine wants the fuel. Was getting some misfires cruising and idling at 14.7. Will do the changes tomorrow.

    Cheers,

    if you have a wideband disable the trim system and tune the idle in while your gauge is set to lambda.
    target lambda 1.
    when done turn your trim system on. if it has an error change the stoich to a lower value until the error is reduced to match the gauge.
