I just performed a complete teach-in on my Evo X MR 2009.
First thing, I flashed the ECU with a new version.
I had 8631A379 (and S/W 0C) and i flashed 8631A827 (and S/W 0B) with 100% succes.
After that i could finally access the PassThru CAN Teach-in.
I did 1 -> 2 -> ignite off -> 7 -> 4 -> 5 -> 8.
I had to retry some procedure more than once in order to have a Normal End, but i always got it.
All without issues. I don't know if it was placebo but a lot of little strange noises went away.
I didn't flashed back my old ECU, was i wrong?
I went for a run and the car suddenly showed a problem: the display turned yellow and i couldn't accelerate (it wouldn't rev). I stopped and restarted and it went perfectly for a while, but this scenario happened 3 times. After that i got home (15 mins run) without any problem.
The oil i drained from the SST was different from the oil i refilled with (red oil drained, filled with Castrol Transmax Dual).
Do you guys have any suggestion?

 

I hope the problem was that the fluids were still mixing up and so the valves were acting strange because of the different (non homogeneous) density and viscosity of the fluid. Maybe now it will be better but I plan to change again the SST oil in order to have the purest oil possible. All the other oils are changed so the car should be good. I don't know if it was placebo but the car was running way better and was no longer making strange little noises.

I just run an evoscan and I found: U0101 TC-SST ECU temporary CAN timeout; U0141 ETACS temporary CAN timeout; P1590 TCM to ECM communication error in torque reduction request.

I searched and looked like someone had the P1590 problem caused to a loosen wire that run from the battery to the transmission, or it could be linked to the car being badly remapped (without touching the SST) so the SST disengage in order to protect itself from damage.

Does anyone have experience with this code?

EDIT: is it safe to go back to stock map? Where can i find a stock map for a 2008/2009 Lancer Evo X MR?

 

Update: I'm trying to read my ROMid with ECUFlash, but i can't.
I've read and tried but i still can't.
I selected my car on the settings, i tried with ECUFlash Ecu Unlocker running in the background, i tried switching the car on the "ON" position only after pressing the read and before the ok. But nothing is working.

Also, i got my problem on video:
When the car try to rev, i'm pedal to the metal all time.
Can you guys help me?

 

Still facing the same problem, and still couldn't read my ROM.
Also, i tried to let the car idle, i removed the MAF sensor and the car didn't die but kept going at lower rpms. Shouldn't a car die when you remove the MAF sensor if it is working properly? Could the MAF sensor be the problem showed in the video?

 

Why didn't you flash the 2011-up firmware?

As for your issues, sorry I don't really know. You ask to go back to a stock map, what map do you currently have?

You might need some definitions for your Evo X in ECUFlash. Talk to some of the tuners here, I've had good experiences with Beeble.

 

Regarding the 2011+ firmware, i read that there were some changes in the SST after the 2009 (i can't remember the exact year) that have improved reliability but "actuators" (i don't know the correct word in english) work with different oil pressure and you could face problem running a newer software.

Regarding the map, i only know that it has been tuned, but i don't know from whom or where. I still have to figure it out why i can't load the new stock map, but thanks for the suggestion, i will try to reach him.

 

DID you ever solve this issue. Im having the same problem. What is your ECU ID. Mine is 52370028. Could find a definition since it was not found in ecuflash. So could not get access to the tables in ecu flash. But I found a Rom here on the forums based off of the definitions of Golden 52370024 and it is working. i am now able to have access to all tables.
Now my SST has been giving me P1833 Shoft fork 4 out of range error only if I take a hard left turn while on more than 50% throttle.
I was able to launch the car at many drga events no problems going in a str8 line or even driving gracefully.
I decided to change the oil and sst filter with SST-F1 fluid used 7.5 Liters.
Tried to do the Teach in with MUT3 but couldn't so I used Pass thru can. Went from the A379 firmware to the A827.
Performed the Teach in. Failed clutch ventilation and shift fork teach in.
I drove the car with the A827 firmware just for about a mile just to see the difference . It felt much smoother.
I then did another teach in and switched back to the A379 as recomended.
Now Im having more issues. After about 2-3 mins of driving I get only 1st-3rd-5th gear with Transmission Mechanical failure Light.
If I switch off the car and then back on all gears are available again but then moments later same thing.
The car wont Launch if launch control is used .
If I floor the car the light comes up as well
