With some help from some key people after finding out that the Evo 10 MR would not run lower than a certain ignition timing at WOT in key areas, we have found a very handy table for the MR.

Even more handy for people that only have access to 91 oct. ;)

The Upper Bound Ignition Timing table for both GSR and MR look like this:

The Lower Bound Ignition Timing table for the GSR is on top, MR on bottom:

As you can see, very handy table to have with the MR as 14-17* from 6500 to 8000 can be a bit much on 91 with a larger turbo. ;)

Awesome findings Bryan! Keep up the good work.

These are the celinng and floor tables in ATR correct?

Nice!

here's something different or i call it a new discovery to share :)

i have 53050006 ROM and this is how it looks like ...

seems like there is a little more protection hmmmmm ??? and the numbers are quite diff ....

thx for the great find bryan

So did some more testing with these this week.

Turns out the "Lower Bound Ignition Timing table" is also used on the MR's between shifts. This is one of the missing pieces to help with boost overshooting between SST shifts.

Log the MR during shifts and see what load and rpm the car hits between shifts and tweak the Lower Bound Ignition Timing table as needed. Less retard will cause less boost overshooting between shifts. Of course becareful you don't use too much timing in this table as this table also bounds the lower timing limit. Meaning the car will NOT go under what is in that table at WOT, even if you have a lower ignition timing number in your main ignition timing map.

Reducing the -20 (less retard) in the cruise regions also helps "soften" the cruise shifting. It won't change the shift speed but it will make the shifts feel less abrupt. I ended up trying out -5 to -7 in that region and it really made the shifts more civilized.

Hope this helps some MR owners.

That looks like your definition addresses are incorrect for your rom.

Another great contribution for us MR owners, thanks Bryan! :thumbup:

ah ha i seee ... can help me out how to find the correct 1 ?

Great find.
