On the lamda table, or any table for that matter, if the first kpa value is set, any other kpa value below that, is keeping the lamda that was used on that first value?
eg:
first value on lamda table is : 30kpa which has lamda=1.01 for say up to 1500rpm
any kpa below that, unless specified otherwise is going to have lamda =1.01 for the same rpm?
