Just for reference, my KID_dir has the following or e2 defined:

Code: Select all

rbase e2 cc59 7231 7256
rbase e2 cc59 7340 7bae
rbase e2 cc59 7cb8 7ceb
rbase e2 cc59 7d3a 7d9d
rbase e2 cc59 7ffe 8014
rbase e2 cc59 8032 8055
rbase e2 cc59 8326 8581
rbase e2 cc59 8797 87ff
rbase e2 c1c4 43b2 443a

rbase e2 c1be 8938 8b18
rbase e2 c1be 8f94 901e
rbase e2 c1be 8d5f 8eb4
rbase e2 c1be 912a 91ae
rbase e2 c1be 9308 93b1
#rbase e2 c1be 9c92 9cb3
rbase e2 c1be 9cfb 9f03

# rbase e2 cc59 8038 8055

rbase e2 c1be a163 a205

rbase e2 c1be a206 a375
So, for A1C:

Code: Select all

423d: 45,e6,00,fc,e2      ad3w  Re2,Rfc,e6       Re2 = b494;
6940: 45,d2,00,fc,e2      ad3w  Re2,Rfc,d2       Re2 = b480;
878b: 45,ff,00,fe,e2      ad3w  Re2,Rfe,ff       Re2 = bd55;
you would have:

Code: Select all

rbase e2 b494 423d END_ADDRESS
rbase e2 b480 6940 END_ADDRESS
rbase e2 bd55 878b END_ADDRESS

Code from A1C is 'slimmer' than KID.

What came first A1C or LHBH1, or was A1C based off LHBH0?
My best guess is that A1C was around March 7th of 88.
LHBL1 was around June 14th or 13th of either 91 or 92.
Again just my best guess could be entirely wrong.

I have no clue on the xxBHx's.

TV_Pres is jumping to 127.5 when shifting regardless of me messing with the above. Time to switch to a newer strat then?

if its going to full tv press thats means you changed aomething to cause that, no stock trans can survive that for any appreciable time

whats the purpose in switching the strat?

Wwhite mentioned “I'm not sure if A1C has SHIFTING STATIC TV CALCULATION.”

I haven’t messed with anything other than what was mentioned and this light throttle slam into third has happened since day one. I’ll cut the tq table and see what happens.

Still having issues with 3rd. Converter unlock/relock is happening after the gear changes. Think we need to find these:

- TMUFN2 = Power off upshift to 2nd unlock time, sec.
- TMUFN3 = Power off upshift to 3rd unlock time, sec.
- TMUFN4 = Power off upshift to 4th unlock time, sec.
- TMUFW3 = Power off WOT upshift to 3rd unlock time, sec.
- TMUFW4 = Power off WOT upshift to 4th unlock time, sec.
- TMUOW3 = Power on WOT upshift to 3rd unlock time, sec.
- TMUOW4 = Power on WOT upshift to 4th unlock time, sec.

I am pretty sure in KID, the following code applies:
And, it appears all values are the same:

Code: Select all

9f68: 45,7e,01,fc,42      ad3w  R42,Rfc,17e      R42 = c226;
9f6d: 33,df,05            jnb   B3,Rdf,9f75      if (B3_FLG_UP_NE_df = 1)  {
9f70: 45,96,01,fc,42      ad3w  R42,Rfc,196      	R42 = c23e; }
9f75: 64,30,42            ad2w  R42,R30          R42 += R30;
9f78: b1,04,34            ldb   R34,4            R34 = 4;
9f7b: a1,00,03,32         ldw   R32,300          R32 = TE_ULK_UP;
9f7f: a2,43,30            ldw   R30,[R42++]      R30 = [R42++];    // loop four times
9f82: c2,33,30            stw   R30,[R32++]      [R32++] = R30;
9f85: e0,34,f7            djnz  R34,9f7f         R34--;
                                                 if (R34 != 0) goto 9f7f;


c226: 33,03               word    333
c228: 33,03               word    333
c22a: 33,03               word    333
c22c: 33,03               word    333

c23e: 33,03               word    333
c240: 33,03               word    333
c242: 33,03               word    333
c244: 33,03               word    333
I'll look in A1C, but my gut is telling me that these codes do not exist in A1C.

How about this code in A1C:

Code: Select all


7bcf: 45,40,01,fc,42      ad3w  R42,Rfc,140      R42 = b4ee;

7bd7: 45,58,01,fc,42      ad3w  R42,Rfc,158      R42 = b506; }
7bdc: 64,30,42            ad2w  R42,R30          R42 += R30;
7bdf: b1,04,34            ldb   R34,4            R34 = 4;
7be2: a1,00,03,32         ldw   R32,300          R32 = 300;
7be6: a2,43,30            ldw   R30,[R42++]      R30 = [R42++];
7be9: c2,33,30            stw   R30,[R32++]      [R32++] = R30;
7bec: e0,34,f7            djnz  R34,7be6         R34--;
                                                 if (R34 != 0) goto 7be6;

b4ee: 33,03,33,03,33,03,33,03,33,04,00,03,33,04,d2,01  ???  
b4fe: 33,03,52,01,33,03,d9,00  ???  

b506: 33,03               word    333

b508: 2d,03,33,03,33,03,9a,04,33,02,9a,04,d2,01  ???  

b516: 00,04               word    400
