Issues saving file on ecu

Recommended Posts

Need help on WRX104X. I have the sequential gear cut wired up to the loom on an 11 and we set the parameters on it and works perfect but once we shut the car off and turn it back on it will not save. Anyone have any idea or have had this issue before  on why won’t save the parameters on the ecu after restart?

I know this is an old thread, but I’m having the same issue. Firmware 6.23.25. I have tried twice now. I’ve made fuel tables, updated parameters, etc. saved multiple times, made sure to  store to ECU multiple times, yet I still open it up after closing and shutting car off and nothing was saved. 
please help!

All that "Saving" does is save the tune file to your Laptop so you can view or edit it offline.

To make sure the tune settings are written to the ECU you must Store to ECU while the ECU is powered and connected.
It may not have successfully Stored if you accidently power cycled the ECU by turning the key to ACC or maybe the USB cable being used it too long/poor quality and the ECU is losing connection to the Laptop.

So it says it saved successfully, and it says it stored successfully, however neither happened. The save didn’t save to my computer, and the store didn’t store. Am I doing something wrong for the store? The key was on key on engine off the whole time. 

Sequence of events: 

1. store successful 

2. disconnect ECU in PCLink

3. unplug USB

Turn Key off. (From KOEO position).

Your sequence of events is lacking.

Try the following;

Key on to IGN
Plug USB in
Open PCLink
Connect to the ECU (F3)
Confirm it is connected by pushing the accel pedal and seeing the TPS value in PCLink reflect this
Make an obvious but inconsequential change to the tune file. (EG. change the Tach output max RPM to 1000rpm higher than it currently is)
File -> Save to save the tune file to your Laptop (give it a unique name so you can identify this tune file later)
Store the tune to the ECU (F4)
Disconnect from the ECU (F3)
Close PCLink & Unplug USB
Key to off

Now turn the Key back to IGN
Plug USB in
Open PCLink
Connect to the ECU (F3)
Confirm the change you made is still present
File -> Compare to open the tune file you just saved and compare it to what's currently in the ECU
This will confirm the file you saved is the same as what's in the ECU.

 

Just to make sure you're aware; when you connect to the ECU PCLink will display the tune data that is currently loaded inside the ECU.
There is no need to "Open" a tune that has previously be saved on the laptop unless you want to overwrite the tune in the ECU with the file you're opening.

Okay thank you. I was just telling the sequence post storing.
I think I have followed the process the way you have shown, but can’t confirm so I will go back to do it exactly like that.

 
I appreciate your help with this, and the “awareness” part as well. I was pretty sure that is what should happen (since the latest should be stored on it) but the confirmation is helpful.
