Andy_Mac Posted August 11, 2016 Share Posted August 11, 2016 Since my car is a bit of an ugly duckling and the ECU doesn't really work with the free software like ECUFlash, has anyone had a play with this one before. Have emailed the guy and he has replied saying my ECU is currently supported out of the box. Think its the same one DTech, the tuner I use, sometimes uses but haven't asked them again if this definately is the one. Wondering whether I should just bite the bullet and pay the money since it'll mean I no longer have to **** around with free software that has rather limited support when things aren't going to plan. http://www.epifansoft.com 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
solidxsnake Posted August 12, 2016 Share Posted August 12, 2016 Looks like it's not much different than ECUFlash or RomRaider. Looks like you'd need at least the "Pro" version to flash your ECU. I'd just guarantee it works with your ECU before you buy it (though I'm not sure how you'd be able to do that besides just trusting the author).

fahr_side Posted August 12, 2016 Share Posted August 12, 2016 I'd check into ECUflash definitions first. I've used SubaruEdit a lot, which is from the same Russian creator. Unreliable, undocumented, unsupported and to top it off just about the shittiest attitude I've ever run into as a customer that you can look forward to when you have problems. I hate using this thing so much I no longer tune Subaru DIT models. ECUedit might be a bit more stable but documentation and support are no better. Get hold of a Tactrix Openport 2.0 and read the ROM off your car with ECUflash. Post the binary to Romraider.com and request the definition, if it's not already on the stock ROM list.

Andy_Mac Posted August 12, 2016 Author Share Posted August 12, 2016 Hmm good to hear some thoughts based on real world experience. Guess thats why its not such a common piece of software to use then. Got a tactrix and all that already. Kinda tried requesting an altered def already without much success. Definition exists but has some faults. Its in the experimental def section as it was never tried on a car. Throttlehappy made a def for whatever software he uses back when he was tuning it, but didn't go as far as making an ECUFlash one, and doesn't seem at all interested in making one now. I'll have another go at posting a request on the romraider forum but didn't get much out of it last time 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...

ptharris Posted August 14, 2016 Share Posted August 14, 2016 Its A2UG000K Hi Andy Do you have the ROM, i have a custom xml for Ecu edit for this car, would be nice to see if it opens this end with correct data. I have tuned several of them and had to make the xml, as mentioned above Epifan is very hard to deal with, rude and generally doesn't want to help when his software has issues! How ever I prefer to use Ecu edit over Ecuflash, just for convenience with the built in logger Link to comment Share on other sites More sharing options...
Andy_Mac Posted August 14, 2016 Author Share Posted August 14, 2016 The original rom that came on the car is in the last post over there. http://www.romraider.com/forum/viewtopic.php?f=8&t=12826 You work for a company in NZ or just do it as a side gig? Did you make the XML from scratch or just make a few tweaks to the 07 spec b one which should be almost identical. So did Epifan not have the correct def for it, since you had to make your own? 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
ptharris Posted August 14, 2016 Share Posted August 14, 2016 Looks fine with the xml I have in Ecu Edit, I have tuned a number of these cars over the years and have made my own def files (based of the xmls supplied with Rom raider) to better suite my needs Are you having issues with Ecuflash? If so what issues? Did Dtech have issues? Can they not supply you with the xml file they used? Epifan does not supply xml files with Ecu edit (i believe this is still the case, however I could be mistaken) Link to comment Share on other sites More sharing options...
Andy_Mac Posted August 14, 2016 Author Share Posted August 14, 2016 Yea problems with ECUFlash, def was made based on a similar auto model that had already been defined, so the tables that differ between auto's and manual's reference the wrong table as mines manual. Thats my understanding of the issue atleast. Problem with DTech was I told one of the tuners about the ECUFlash issue but he ended up going over to the states for some tuning for a while so their new guy, came from STM I believe, didn't know this so used ECUFlash and couldn't work out what the issue was so thought the ECU was somehow locking wastegate tables so just tuned everything else and left boost control as it was. They've contacted someone about getting a def for ECUEdit. Assumed it was Epifan themselves but if they don't make them then it may have been someone else who writes them. 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
fahr_side Posted August 15, 2016 Share Posted August 15, 2016 The def seems fine to me, maybe you have an older version. You're correct that not all of the DTC you've listed show up but you're probably not throwing those codes. Try unplugging the TGVs and air pump before permanently removing them and see if the codes P0411 etc. show up. I bet they don't because they are not implemented on your vehicle. By 2006 Subaru had pretty much stopped doing the oldskool trick of one ROM for both AT and MT versions and a pin to ground to tell the ECU which car it's in. There should not be AT tables in this ROM and I don't see any as it's defined now.

Andy_Mac Posted August 15, 2016 Author Share Posted August 15, 2016 Airpump/TGV stuff is all working fine, they were removed a while back Just disabled the codes that could be done and ignored the rest as the others over here suggested. Never bothered trying to run it without the codes disabled to see what would happen. This is all coming from throttlehappy/kido_tune/Matt. Don't know enough about it myself but that was the conclusion he came to. He writes a few defs so figured he knew what he was on about. It made sense at the time. Do you have any other thoughts on what the issue could be then? Other than Matt who seemed to think he had it sorted by using a different def file, the first and 3rd tuners who have had a go at it had no control over wastegate duty cycle, and probably a few other tables. Setting the whole table to 0%, 100% or whatever inbetween made no difference to what it made. Were you looking at the ECUFlash or Romraider def? 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
fahr_side Posted August 15, 2016 Share Posted August 15, 2016 I was looking at the ECUflash def as I only use RR for it's logger. RR doesn't have a stable definition for this ROM and anyway always lags behind ECUflash in defs. So Matt was saying the WGDC tables as defined are actually the AT tables, which the ECU shouldn't be using, so editing them makes no difference to boost control? Matt's a good tuner and so he's very busy. Can be hard to get his attention sometimes. I've been working on a tune on A2UH000A lately and can tell you that has no MT / AT tables at all. You may also look into what other ROMs will run on your ECU as a different version may have a more complete or accurate definition. A2UG000N for example is very well developed. Of course as it's a ROM for an EJ255 car you will have to copy and paste every value that's different from the original file to the new ROM file but it should fix your problem without any help from the adepts. Do a test write and if you get a warning that it wants to overwrite protected areas then you'll know the hardware isn't compatible.

Andy_Mac Posted August 15, 2016 Author Share Posted August 15, 2016 Sweet, yea have always used ECUFlash Can't remember if he said wastegate duty or target boost but either way no amount of fiddling with different tables would give different boost results. Thats where I was thinking I could somehow use the 07 JDM Spec B one as it should be identical from a hardware standpoint atleast. Would be A2UI000K. Was also wondering whether it'd be possible to just use the def for that one and internally rename it as my ID to see if that works. Don't think a ej255 one would work as it'll only have single AVCS setup in the rom wouldn't it? How do you go about flashing a rom for a different car to the ECU? Say it's loaded up in ECUFlash will it just let it write or spit the dummy because the ECU ID will be different? 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
fahr_side Posted August 15, 2016 Share Posted August 15, 2016 Ah yes, you have the same DAVCS heads as the JDM model, so no EJ255 ROM for you. A2UI000K looks like a good candidate for you. Very few differences between yours and this one. Renaming the def isn't going to do it, the addresses of tables that have the same values in both ROMs are different. The good news is that values in boost target and WGDC tables are different between the two. You can try a test write. If there's something so wrong it would brick the ECU ECUflash will tell you you're trying to overwrite protected areas. If it test writes okay you may flash it for real but it's still possible the new ROM will not start or run the car. If that happens just flash the current ROM back in. Of course a cautious person would be sure he had access to someone who can do SHbootmode recoveries, just in case.

Andy_Mac Posted August 15, 2016 Author Share Posted August 15, 2016 Not sure about the stock rom on the Romraider site for that one. Rom seems to be a weird size, way smaller than the others. Did you have a look at it from on there or elsewhere? A2TB100K may be another option. It's listed as a JDM 07 spec b manual aswell but runs slightly more boost and other settings for some reason. That shbootmode recovery doesn't look like much fun so really wouldn't want to get to that point :/ 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
fahr_side Posted August 15, 2016 Share Posted August 15, 2016 Not sure how you came to that but the file I pulled off the stock ROM list has the full 1048576 bytes like all other 32-bit ROMs. There are six fewer tables defined for it than A2UG000K but the size is the same. IME the more differences there are in the CALID the less likely it is that it will flash and work. I think A2UI000K is your savior unless you're willing to wait for the adepts to go through the definition for A2UG000K and fix the errors.

Andy_Mac Posted August 15, 2016 Author Share Posted August 15, 2016 Yea realised I was being an egg and using the windows unzipper rather than winrar which only states the compressed size not the full size. All ok now. Had a call from the tuner this morning who managed to get hold of the ECUEdit guy and have got a def file for the A2UG000K rom he's had a play with it already and with the new def can see two tables for the same wastegate duty table, the one he set last time and another one so he's hoping his other one will behave as its supposed to. Booked in to see them again on friday so hoping it works as they think it will Cheers for the help so far fahr_side, hopefully I won't have to go down that route 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
Andy_Mac Posted August 19, 2016 Author Share Posted August 19, 2016 Alright, some good news. Boost control worked out fine with the new def in ECUEdit. Didn't make any more real power, but wasn't expecting too. But the boost curve actually looks like a curve now rather than a big spike and then bugger all. There were a few tables that weren't defined properly apparently so hopefully they can be sorted and then it'll be spot on. 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
