Default MIL issue: wont illuminate when ses triggered

Its a lm7/p59 conversion in a 58 apache.
light comes on with the key and then turns off once running.
if i command it on/off with hptuners, it works as it should.
however, it wont illuminate if it throws a "ses enabled" trouble code.
im a little confused by this, and curious if anyone else has experienced anything similar and if they were able to resolve it?

Not al DTCs cause an immediate MIL, some of them need 2 fails to illuminate. What DTC is on?

thats what i considered at first.
originally i was getting a pending/current dtc for both knock sensors p0327 & p0332 if im not mistaken. (junk aftermarket sensors DOA)
i thought it was odd that i didnt get a light while i was scanning.
so, i disconnected a couple different sensors while it was running to see if i could trigger it.
maf.
map.
cts.
each of those should trigger an immediate ses light. dtc pops up on hptuners, but ses light doesnt turn on.
command it manually with the scanner and it works. go figure.
