Request ID: Open/Closed Loop?
Request ID: Open/Closed Loop?
Anyone know if there is a request id that logs whether or not you are in closed loop verses open loop?
I am trying to solve some low load knock issues and if I could log open vs. closed loop it may aid in solving my problems.
I am using mitsulogger at the moment to log.

There is a requestID or a way to log it at least, but I don't know the requestID or variable to log. One of the disassembly guys can probably tell you.
Otherwise, just use the method mentioned above.

If I understand it correctly it is MUT_18
bit 0 = open loop due to acceleration?
bit 1 = open loop due to engine load or fuel cut due to decceleration
bit 2 .... bit 14 unknown - I am working on it
bit 15 - closed loop

Seems to be word 
In 88590015
In 88590015
Code:
00016482 bsr sub 16728 (IS_CLOSED_LOOP_ENABLED) 00016484 nop 00016486 extu.w r0, r0 00016488 cmp/eq #0, r0 0001648A bt 1649A 0001648C mov.l @(h'90,pc), r10 ; FFFF6BEC (Open_Loop_Bit_Array) 0001648E mov.w @r10, r0 00016490 mov.w @(h'88,pc), r11 ; h'1000 00016492 or r11, r0 00016494 mov.w r0, @r10 00016496 bra 164A4 00016498 nop 0001649A mov.l @(h'84,pc), r10 ; FFFF6BEC (Open_Loop_Bit_Array) 0001649C mov.w @r10, r0 0001649E mov.l @(h'84,pc), r11 ; h'EFFF 000164A0 and r11, r0 000164A2 mov.w r0, @r10

We will probably see one byte with MUT_18, but variable is word that is associated with that MUT request.
