    Default Zeroiing E005, pilot coolant temp multiplier disables ALL pilot activity?

    I have my tune set up to disable pilot on the main table above 1800rpm and to start tapering it off on higher load at 1500rpm.

    I wanted to keep more pilot when the engine is cold up to 2200 rpm, so i adjusted my E0008 table accordingly and set my pilot coolant temp multiplier (E0005) to Zero across the 86* range.

    Now everything runs as intended, until the engine gets to 86*, then ALL pilot activity stops. I increased my main pilot quantity minimums (E0002) to 4 thinking it maybe didnt have enough duration after the additional "cold temp" pilot cut out, but that still didnt help.

    Yes setting any multiplier value to zero will shut it off when that parameter is met.

    thats unfortunate, i was hoping it only affected the values from E0008, coolant adjust, table, and would leave the E0002, quantity base, table alone.

    So then if i put say 0.5 in E0008 table across that 86* range , the 0.5 value will modify the SUM of both tables....theoretically i could modify the duration values above 1800 rpm etc etc to be too small to be recognized over 86* and still achieve my desired result....

    odd that the pilot tables calculate this way, when the post injection tables do not.
    on table E0069(post quantity coolant multiplier) i have zeroed out the post injection at the higher temperatures and it only removes the additional amounts from table E0066, not disabling ALL post activity like the pilot tables will

    after extensive testing & logging, i can not get table E0008(pilot quantity, coolant temp adjust) to add ANY fuel to the pilot amount at any operating temperature.

    E0005(coolant temp multiplier) is definately working though, & modifying table E0002 (pilot quantity base)
