Those two are fine, I found mine taped up under the dash on the same harness as the green plugs and flash block.

I have the same two black wires with a red stripe. Strange that they'd leave terminals crimped on with no plastic connector. Makes me wonder what they are for now.

That's good to know. Thanks for taking the time to look. Makes me feel alot better.

If it helps any my car was just in the shop due to the fact the air bag light was stuck on. I had to take it back 3 weeks later, for them to solder a connector under the seat (they said is was common on legacys but they never saw it on a wrx).

This is about the only time the dealer (or anyone else) has touched my car (I service it my self of course). Maybe mine were dangling cause they did something with em?

But thanks again for looking.

"Just take some 20 gauge wire and crimp on a 0.250" male "blade" connector onto each end and jump the wires in the block, make two of these jumpers if you have a my2004+. "

I ran out to "The Shack" and got those blade connectors. I just poped my head under the dash again and I don't see any way that they will fit (Its getting dark so it was hard to see).

Seconldy, there seems to be 4 pins. Which pin gets jumped to which pin(2004)? Thanks

Oops, I guess you need smaller blade connectors for the 2004. I have a 2002 and the female sockets are 0.250". Sorry for the bad advice on that one. Just use a piece of wire and tin the ends so that they fit tightly in the female sockets. I've done that before too.

On the 2004 the wires to be jumped for flashing are in pairs vertically to each other in the plug.

Ie, if you hold the notch tab at the top jumper the two "columns" not the two "rows".

I have a usertuned ecu.

Will using this tool cause any problems with my usertune flash?

what is a "usertuned" ECU?

ECUTEK remap option. They re-use the Auto maps to give the (map switch) functionality - boost/wastegate. Single byte value (0-255) signals what user-tune values are changeable. accessed through their deltadash software or their dash monitor hardware product.

other user-tune parameters include:
- rev limit adjustment
- overall ignition adjustment
- open loop fueling adjustment
- selectable boost map
- boost pressure adjustment
- selectable wastegate duty map
- wastegate duty cycle adjustment
- idle speed adjustment
- vvt intake cam timing adjustment

He may be talking about a UTEC as opposed to ecutek, first thing that came to my mind when he said usertune. Basically a standalone unit that alters the parameters of the ECU and feeds it back to it.

Hey, Colby.

Since I'm not using Windows/DOS, could you point me to the information I need to write a program to do the same thing mentioned above but on Linux? Somehow the magic string "4D FF B4" just appeared here but there seems to be no other reference to it anywhere. And what's in the new kernel?

There seems to be a breakdown in communications and I'm wondering if there was an old forum where this was posted. If it's on another forum, could someone post a link?

Hi guys!

I am new downloading my rom I have only been using various logging software and it would be great if someone could give me a rundown of what needs to be done what I need to do to download my rom...
Do I need to connect any other cables besides from my tactix cable?

My car: Subaru WRX STI -2003 (Euro/Uk spec)
cable: tactix wrx-type

Maybe I'm biased but if you download my ecuflash gui v3 from this section it includes everything you need.

Unzip it into a directory like c:\openecu\ and run the software.

You can then easily select all different options without having to do any command line typing.

Question for Colby.... I have an AF22 ECU that I can't make this stuff work on... I can do everything up to uploading the kernel, then it's all quiet after that. I'm treating this as an 02 ECU as far as the OpenECU software is concerned.
Is this ECU too early to be supported by the current kernel? Am I missing something else? Looks like it should work.

Ta.

It should work. Is there any chance I could get a hold of the ECU? I have others (AF423) that I could swap with you...

Colby

Interesting. Maybe I'm just doing it wrong.
As for sending it to you- possibly... let me get back to you on that.

Question about the kernel; it is encrypted as it is sent up to the ECU; is this standard bootloader code for that micro or is it a custom bootloader Subaru have stuck in there? And if this is the case, how on earth did anybody find out what the encryption was?

The kernel is written by me. It is "encrypted". There are tricks to reading ROMs out for the first time. Once you have a ROM image, you can disassemble it and figure out the decryption method for the bootloader, and then write your own kernel, make it checksum correct, and encrypt it.
