Evandg Posted September 13, 2022 Share Posted September 13, 2022 Hi there, I have bought a tactrix 2.0 cable recently to flash my car. The car is a 2003 JDM Subaru Legacy 2.0gt spec.b (BP5). The computer is running windows 10. Whenever I try to read the (supposedly) stock rom it comes up with an error and the odometer display says “Er HC” I have tried different combinations of ignition on before and after clicking ok in ecuflash, green and white test mode connectors connected and disconnected, etc. this is all using the sti04 setting in the program, as recommended in the forums. I have also tried others like subarucan and I believe sti05? And no luck. Attached is a photo of the log. Anyone able to provide support on this? I have seen a local tuner save the rom off the car successfully a while ago so I know it is possible. Thanks! Link to comment Share on other sites More sharing options...
m sprank Posted September 15, 2022 Share Posted September 15, 2022 Never used Windows 10 with ECUFlash/ROmRaider. ER HC is a comm error. IIrc there is a specific timing/pattern to turning the key to the "on" position with that set up to make the initial connection work. It has been a long time. Maybe another member can chime in.

seanyb505 Posted September 17, 2022 Share Posted September 17, 2022 (edited) Maybe try outback or Forester? I have the timing written down somewhere, will look for it. Edit - Here's the order I use: Connect Green test connectors Connect Taxtrix to Computer Turn key to on Open ECUFlash Select Appropriate Vehicle Open Rom Image from Computer Test write image to vehicle Click Ok Write to ECU Click Ok Fan noise stops will start writing temp goes up, and odometer shows er hc Click Ok turn off key Unplug Taxtrix from computer disconnect green test cables turn Key to on - let sit for a few seconds to recognize changes - about 15-30 - then start car - let idle for a few minutes without touching throttle As for the vehicle, I think I use one one these, likely the last one: I'm assuming you're already using the top one, which to me also seems correct. What is the quality of your USB cable? High or did it come with a gas station phone charger? I've had to switch USB cables for btssm app simply because a cheap one stopped working. I'm by no means an expert, this is just how I would approach the situation, and then see if any research would back that up or bring me to a different solution.

Did you get it working? My 2003 JDM Subaru Legacy 2.0gt spec.b (manual) is very picky on the timing of reading, i.e. the first connection to ECU. The way it works for me: Key turned OFF Connect the green connectors, openport to laptop, etc. Start ecuflash, select sti04 as car Click "Read", which will open a pop-up message about key turned on, then hover your cursor on top of the OK button Turn key to ON and immediately click OK on the read pop-up the trick seems to be quick timing, that's why be hovering over the OK button when turning key ON Connection should be made and reading started, from now on it stays connected for read/write/compare until you turn key off Also do you have orginal or chinese knockoff OpenPort2 adapter ?

1lukeschmidt Posted February 23, 2023 Share Posted February 23, 2023 Hi Evandg, did you ever figure this out, or get it working? I've got a 2006 JDM LGT spec b, so I'm in a similar situation trying to figure out how to use my tactrix cable. 1 Link to comment Share on other sites More sharing options...
NZTunedBySTI Posted June 17 Share Posted June 17 Anyone sort this problem out? I’m having the same issue with my 2006 JDM 2.0 Spec B Tuned By STI? Can’t seem to flash ecu no matter the timing or sequence of the key. Thanks in advance Link to comment Share on other sites More sharing options...
m sprank Posted June 17 Share Posted June 17 Welcome to the wonderfully frustrating world of open-source. Its finicky and glitchy and there is a reason most reputable shops refuse to work with the software. It is OK at best when it works. Link to comment Share on other sites More sharing options...
