Mattjin, sei sei (TQ) ni hau pang (You are great!)

Mattjin

Shenme!!! Ni shuo wo hen pang??? ((What!!! You say I am very fat???))
Or did you mean xie xie, ni hao bang :-) haha

No problem. As I was saying, once I find the maps it is not difficult to find them for other cars. Today I am fairly sure I found another couple of maps.

For 80700010 :

A quick description of the maps.

The scales and OBD are found as per the new EVO9BASE file that comes with V1.37 ECUFLASH. I saw them for the EVO9 and new they must be there for the EVO7 as well.

The ignition coil maps were found today. I am 99% sure they are correct, but I need to get a scope on the ECU ignition signals to see if it is right for certain. Lowering the number in the Coil Charge Time map definitely makes the spark weaker, and I was already pretty sure there was a dead time map that went with it. DO NOT TOUCH THE MAPS unless you are absoutely positive you need to do so. Increasing the number will most likely result in a couple of melted coils so use these maps at your own risk. I actually stumbled onto them while playing around with the knock control routines. As per another thread about knock control, I am also 99% certain I found the 1D map point that controls the max knock sum that the ecu can use. I will post this when I do a little more testing. So if you are sure you have heavy false knock you can drop the max number down from 36 to a smaller number to limit the knock retard. At first I thought the coil maps were part of the knock sum filters and by chance I decided to lower the numbers. Lucky I didn't go higher and blow the coils to hell! There is a third map but it is a flat number across it (255) so I am beginning to think it might be a trigger edge (Falling or -ve edge). Changing it to 0 may make it a Rising edge. If this is found to be the case it means being able to directly drive CDI units requiring a rising edge such as MSD or Crane units from the ECU. I hope the testing proves this is the case.

finally someone to take over me for the 7.5 !!

Have fun ..

The gearbox controls starts from &H43000 onwards .. have fun
Hope you have lots of fun changing the clamping force and the lock rpms as I did ..

Now I'm starting on the SST

Mattjin

Can you post up just one of the maps, and I will start looking for the rest?

43000 ???

Will test the next fine day

Tranny maps are from 3FF40 on 83540008

monsta

Start with this map

&417eb 14X10 Pretty sure axis is throttle voltage vs rpm

Throttle voltage should be

0.5
1.0
1.5
2.0
2.5
3.0
3.5
4.0
4.5
5.0

Should be Torque converter solenoid related

Oh yeah- edit on my previous posting about solenoid duty. 0% is unlocked and 99.6% is fully locked. I was having a brain fade that day

OK, the first big thing for me. I never knew the GT-A rom was 512k! Either I am a complete idiot, or better yet it teaches me to never take anyone elses work for granted. Doing a normal ROM Read sucks out only a 256k rom. Today when I saw Gunzo's post about locations around 43000 it all clicked. Normally the 256k rom doesn't go that high and I was positive I have been over almost every map within 256k and none of them were related to the TC lockup. So this afternoon I tricked ECUFLASH into doing an Evo9 rom read on the Evo7 and what do you know... out comes a 512k rom with alot more maps.

It makes sense now. The 8xxx series roms are 512k, the 9xxx series are 256. So basically all of the Evo9's out there have their ecu's based on the first of the 8xxx series, the Evo7 GT-A :-) Straight away I saw alot of new maps and also found the large 14x10 map along with alot of 4x5 maps and even more 2D maps. I just haven't spent any time searching for scales yet. Thanks Monsta, I will do some playing tomorrow with the 14x10 map.


For those of you that want to do a proper rom read, here is how I had to do it with V1.34 Ecuflash. You cant get a 512k rom from an Evo7 read, and you cant read the GT-A rom with an Evo9 read either.

1. Go into the "rommetadata/read templates" directory. Select the "read_evo7" file then copy and paste it back into the same directory so you have two copies of it.

2. Rename the new file to "read_evo7gta".

3. Open the new file and change the memmodel setting from SH7052 to SH7055 and save it.

4. Open Ecuflash and do a Rom Read. There will be two lines allowing you to select evo7-8. Select the second one and do the read.

5. You will now have a 512k file with all of the maps. Save the file.

6. Backup your old definition xml file before modding it. Open it.

7. Change the memmodel to SH7055. Save it.

8. Open Ecuflash and open your rom. All done.

monsta

now it makes sense why I wasnt able to find your auto maps.

The of the 2d maps are used for INVECS fuzzy logic. The 4X5 maps are more solenoid ones.

Would you be able to post your 512k rom so I can add that to my rom list. It will help transfer your work over and check etc.

Mattjin

I will do stock rom read tomorrow and post it. At the moment I only have my current tuned map which I need to keep to myself ;-)

monsta

Absolutely understand

Alright- Ive been holding out on a small amount of info and though this would help Mattjin to disassemble the Auto tranny stuff quicker.

Because of the amount of power I have, I found where you control the tranny clamp pressure and shift speeds.
If you set the shift pressure to 100% duty the changes are EXTREMELY voilent and as such takes a bit of trial and error to find the harshest that you would like for the power level you have.
I have mine set to 100% for my drag map

Shift time wise ive set all the maps to 20msec across the board. Any lower and it makes no actual difference to the shift speed. this is quite abit quicker than stock.


Please be aware that changing these maps will reduce the life of your trannys clutch friction and plates, but will enable you to run ALOT of power through the stock tranny.


I didnt take any further time to find the downshift maps, but will do so-Mattjin will be able to isolate pretty quickly with disassembly.


They are 2d maps with duty vs load and time vs load

monsta!

Great find! Wow you have surely gone to the dark side of airtrek tuning hehehe May the force be with you hehe

Now where can I find the gear shift display in auto mode hehe? Mine is still disable sign...

Cheers all!
