I’ve looked at the 00 GTP bin and 97 regal bins. Code is the same as far as the switch is concerned.

Re: P04 Custom Code
Usually there is a setting associated with that switches. Maybe there is enable bit too, time to be pressed on, There is also visual confirmation[a switched ligth] when the mode is activated.
We need to find the logic that handles this. I know there is different kind of modes. Manual, performance,hot, normal for all bins. Usage depends on some settings I guess.
zack4200, this is from a paid program that starts with ALL, uses the same schematics from techline, but it is easier to navigate. Downside is not all data is available, and some charts are missing.

2nd_Gear_Start_Lamp_On_Car -present/not present
Type_Of_Shift_Pattern - ???class2/pcm
Shift_Patern_press_Time -time for switch pressed to activate
2nd_Gear_Start_Switch - switch)type fitted
2nd_Gear_Start_press_Time -time for switch pressed to activate
I know these are available in calibration, but have no way to find them. If you find the logic and mark them will be great.

Re: P04 Custom Code
I’ve not been able to wrap my head around how the trans tables work yet. I’ve spent no time doing it but it’s quite crazy how many indirect addresses are used.
Hard to follow Indirect addresses of tables of indirect addresses of tables.
When I sit down and can actually follow it, it should take very little time to find it.
I have seen a few undefined trans shift logic tables. No ETA on when I’ll figure it out though.

Re: P04 Custom Code
Started to work the Multitable read subroutine. Trans Lookups make a lot more sense now. But I'm VERY early on.
Re: P04 Custom Code
Some snippet how index, double index, triple index and offsets for table lookup are used. When you have them labelled they all follow same order
Main index for code lookup
Offset for table addresses.
Than it is matter of counting dwords jumps to get which one table is used.

Re: P04 Custom Code
Yes, I was already noticing that, but that helps!
Can anybody tell me what URBAN tables are?!?

Re: P04 Custom Code
Also, I think there's a bit of code for Performance Mode 3 that will potentially alter table lookups. This could be the link to 2nd gear start tables... I'll continue to do some digging.
There are a total of 10 different Transmission "modes" to determine shift points/quality. But there's 11 table sets...
Performance Mode 3 chooses mode 1 or 7 depending on another variable I haven't traced (or can't), it might be a traction control variable.

Re: P04 Custom Code
Yeah there could be some special ones, traction or abuse, or limp home modes.
