Ok soz mate never seen this I'll do it just now ��

The actual values are encoded as opcode immediate operands, which is why they're at the addresses they are. The advance limit should be easy to find in any SH2 Mitsubishi ROM disassembly by searching for "mov #0x46" as that seems to be unique in these ROMs. The retard limit will normally be a "mov #0x0A" instruction preceding the advance limit instruction in the same subroutine, though not always the immediate preceding instruction as it is for the above ROMs; note that this instruction is used in a number of other routines in each ROM which aren't timing related hence the need to search for the advance limit instruction first. NB: the operand encoding may need to be adjusted to match the disassembler output; the instruction text shown matches the output from logic's SH2 disassembler.

Great job WytWun {thumbup}
Since you have the disassembley skills, I ask how hard would be to develop proper antilag for those roms? Similar to the Subaru GroupN rom.

Great work WytWun, any chance of those address for rom id 96260009?

WytWun Feb 7, 2016 12:20 AM

Definitions for a couple more ROMs...

96260009:
Code:

<table name="Ignition Retard Limit" address="17acd" category="Timing" type="1D" level="2" scaling="TimingMUT" />
<table name="Ignition Advance Limit" address="17acf" category="Timing" type="1D" level="2" scaling="TimingMUT" />

96940011:
Code:

<table name="Ignition Retard Limit" address="18975" category="Timing" type="1D" level="2" scaling="TimingMUT" />
<table name="Ignition Advance Limit" address="18977" category="Timing" type="1D" level="2" scaling="TimingMUT" />

The 7 and 8 ROMs I've looked at so far have the stock limits as -10* and 50* (retard and advance respectively) while the 9 ROMs have -20* and 50*.

Thanks a lot, WytWun, I will try that and report back here when I get home next week. {thumbup}

I have tested with 96260009 Ignition Retard Limit, confirm it's working, thanks a lot WytWun.

Hi,


I`ve configured the 96530006 Setting on my 96531706.
on my tephra map it Shows Retard -10 and advance 50.
is this ok? I expected something like 220?
cam I just set the Retard to -20 instead to -10?


thanks

E6 25570000 rom id, can't go lower than -10.

Is it possible to know Ignition Retard Limit address?

Forgive me of my RETARDATION but is this mod to be used for the launch maps??
And also,, so my other question is,, is there no need to add negative timing in the launch map,, but only simply to change the numbers in the Timing Retard Limit #1 to achieve the negative timing im looking for..
And do I need to change both
Timing Retard #1 and Timing Retard #2
Thanks,,,

93660005 & 93670005:


Code:

<table name="Ignition Retard Limit" address="174b3" category="Timing" type="1D" level="2" scaling="TimingMUT" />
<table name="Ignition Advance Limit" address="174b5" category="Timing" type="1D" level="2" scaling="TimingMUT" />

Not so much for Launch maps, Launch doesn't need so much negative timing, it's more for Anti-lag when off the throttle but are limits for any map. For launch you would still want to put negative timing in the maps. The limits are just what the ECU restricts itself to, where the retard (negative) or advance (positive) timing limit is the maximum it will ever use. So if these limits are less than what are in your maps (any maps) then these limits are as far as it will go. And yes you need to change both Timing Retard limits when setting retard limits.

Thanks.. Ya I use the nlts tephra mod so do we have to modify any of the other maps?? besides the Timing Retard limit (203) and change ,mess around with that,,
I have played around with it and changed it.. and tested it on my launch map and have seen -16 timing + flames lol..

sorry for reviving this thread but 96530706 cant seem to work i keep on getting error in ecuflash after adding these new tables and scaling
