Default '02 Can't Reflash

well, I have had my tactrix cable now for about 3 months and I haven't had any problems, but the other night I reflashed a friends car, and then immediately I tried to reflash my car and wasn't able too. I used ecuflash and it wasn't able to connect to the ecu. (screenshot of error below)
I have tried reinstalling ecuflash 1.3, 1.29a, and 1.28. I also uninstalled all of the drivers and then reinstalled them manually each time I reinstalled ecuflash. I have checked to make sure the flash block is installed and the green connectors are connected. I also checked the cable itself for any visible problems and didn't see anything.

I did try to log and that works fine. last time I reflashed my car was about 6 weeks ago, but I have reflashed 2 other cars within that time frame without any other problems.


That was about 2 weeks ago


Now:

I still haven't figured out why I can't flash to my car, but last night I tried it on an '06 and it reflashed fine. I immediately tried it again on my car with no luck. I double checked all the connectors again and everything still looks fine.

Anyone have any ideas?

Thanks

Chris

1. Does it enter test mode when the green connectors are connected? Radiator fan\fuel pump cycling?

2. What was the last rom you flashed?

3. Have you tried just doing a read instead of a flash?

1. Yes, the CEL flashes and the fuel pump and fans will cycle.

2. the last rom I successfully flashed was the stage II XPT rom.
Recently I have been trying to flash an updated version of the same stage II rom, but I have tried different roms too.

3. I have tried to read, test write, and write.

strange. The fact that it will flash other cars just fine means the issue is with your car and not the tactrix cable/driver installation. I would try a hard reset (disconnect battery).

Ok, just got back from disconnecting the battery and it's still doing the same thing.

The battery is only about 6 months old so I don't think that is a problem, but no, I haven't checked the voltage.

Any other ideas?

Check the jumper block.Maybe the wire pushed out.I thought you had to be quick and get the program started before the fans started to cycle?Also check you OBDII connections.Maybe a pin got bent or the connector is pushed back.

just checked the wire connections into the jumper, the white connector, and both green connectors .. they all looked good.

checked the cable for bent pins, they are all straight. Also checked the female side for any debris or blockage and didn't see anything there either.

When I start the process I will hit "ok" on the dialog box at the same time as I turn the key, but I have also waited to hit "ok" a 1/4 - 1/2 second after I turn the key and either way it's still the same result.

Just went out and tried ecuexplorer to see if the results were any different... here are some screen shots




This is the error I get when I try to read the ECU


What do you think?

Not sure. Perhaps there was a problem during the last flash. Did you get the message that the flash was successful the last time you were able to flash? Did you do anything related to wiring in your car?

Yeah, everything was successful .... I had done it previously maybe 10 times and the last time I did it, it was the same as all the rest. At that point I was pretty satisfied how the car was running and left it alone for awhile. Then I got a new revision of the map and tried to flash it and thats where I am now.

The only thing I did with the wiring was I put a switch in for the green connectors, and the switch works as far as putting it in to the test mode. Since this problem though, I have taken the switch off and connected the green connectors the normal way with the same result.

I did notice today though after looking through the wiring that there is a black connector that isn't connected to anything and I couldn't find anything to connect it too. I figured it was just an extra connector that had been taped somewhere I hadn't noticed it before.

The flash block and the green test mode connectors are all you need to worry about for flashing for your car. At this point, I would try swapping ecus from another 02-03 wrx and see if you can flash. If you still can't, then it is not the ecu. If you still can, then it is the ecu.

I have the same problem and have noticed that if you use the reflash and cable on any particular vehicle the OpenECU software and the Tactrix CABLE will lock itself to first ECU flashed. Don't lose or damage those cables people.

I found this out was by purchasing a brand new ECU just in case something went terribly wrong I would have a back up ECU from Subaru. First thing I did was test the extra ECU to see if it worked. It worked just like the original.

So I proceeded to reflash my original ECU, which worked and then swapped in the extra ECU. When I tried to reflash that extra ECU I could not, so I put the original ECU back in, guess what happened, it flashed perfectly fine.

I wish someone would have told me about this before I purchased this cable. Now what happens if this cable gets damaged or lost, I can not reflash my car ever again? What happens if you can not replace your ECU like on the newer drive by wire model vehicles with immobilizers? Could you be stuck with a crappy map that will blow up your engine?

Help, maybe I am missing something please clarify...

it definitely does NOT marry itself to an ECM. The cable i am using has been used on at least 5 different cars. Downloading and uploading.

I doubt it is a driver issue considering he's flashed 4 other cars no problem with the same laptop and tactrix cable.

This thread sounds eerily familiar:

http://forums.nasioc.com/forums/show....php?t=1231955

So are the XPT images behaving like ECUTek and the other vendors?

I don't think it's my laptop or cable after I was able to reflash another car, but I am gonna ask a friend of mine if I can borrow his laptop and try it just to be sure. Another reason I don't think it's a software problem is that I have completely removed and installed ecuflash and drivers multiple times.

I can't say for sure that the XPT map isn't the problem, but I haven't had any problems before when I have swapped XPT maps for other maps including the stock map to run some logs. It just so happend that when this problem started I had an XPT map (same one that I flashed over previously) on the ecu.

well i was getting the same error, going crazy trying to figure it out, then realized i simply wasnt doing the process in the right order. connect the green connectors, go into ecuflash, click reflash until the dialog box comes up with ok and cancel, THEN turn on the ignition. the car should NOT go into test mode. the cooling fans and fuel pump should stay silent. you then click OK immediately after you switch on the ignition. if the fans go on, you either didnt get the reflash dialog before you switched the ignition, or you waited too long to click OK. i felt like such a moron after i figured this out. :-P hope it helps.
