Like the title says. No issues otherwise. I can't get a few codes to not set with out the mods installed I think. Seems to act more like a security feature keeping the car from running. No codes in any module, scanned with snapon solus edge. If I flash in a rom previous to applying the mods car start and runs with no issues. But codes for cat and intake runners set as they are removed from car.
Thanks, Brian.
I have had nothing but problems and zero support from HPT with subaru. Same issue on a 2012 and 2011 STI. Even had the 11 flashed back to stock at the dealer and the OS build changed so wanted more credits even though the VIN number stayed the same. Again no support. The 2011 car scrambled my torque tables and timing when I flashed so I returned it back to stock at the dealer which caused HP Tuners to want to meto buy 4 more credits again. I have emailed and no reply. I'll use HPT for my other vehicles and open source for subaru for now.
What is your ticket number?Quote:

Like I said I'm on my second ECU now in the same car 8 credits down the drain so I had to buy a tactrix cable andflash back to stock as it jumbled my smode torque tables on one and my timing tables on the other after a read. Once I flashed back with the tactrix open source to a stock file it told me I had to purchase new credits again. Let me look tonight and find the ticket number. Thanks for the reply!Quote:

Charlie at HP Support was a super big help when I sent him all of the info he needed.
Technically speaking it should NOT. As outlined in the Subaru HPT Custom features patch guide when you patch the file it SHOULD be set to MAF, we even advise to keep it set to this until you are comfortable with switching to speed density.Quote:

Preview of the SD vid
Mind taking a peeAttachment 119592Attachment 119593k at this? I've went through two ecus before buying a tactrix cable to fix the second. Now it wants me to relicense the ECU since it has a different stock os on it. I just read the file with HPT and the base timing tables are all skewed. Before on the original 12 STI ecu it just scrambled the torque modes when reading. Now on this ECU it distorted the base spark maps. Jeff Evans's courses are great for subaru I agree! I linked the original read and the hpt added file. I would like to submit a case to see if HPT can work with me on the original 8 credits also between the two ecu's.Quote:

I checked, it was a simple definition error with the wrong axis sizes causing it to skew. It's fixed now, next time you open your file it should reflect the changes. As for the credits, you'll have to email support as that's not something I personally can do.Quote:

In the ticket I had posted the following info " I uninstalled my cobb AP then flashed with hpt my original saved rom then it failed to flash several times stating invalid checksum and the car would not start." I then realized (after submitting the ticket) what was wrong with it was the rom had been opensource modded after all before the ap had been installed and that changed the checksum value so hpt didn't recognize it. I downloaded a stock AZ1G401V rom and opensource flashed it to the car. Once done, I read that with hpt, saved it, then flashed the hpt stock rom to the car. It didn't ask for more credits or anything. Now, here's where it gets tricky, I then patched the new hpt file with hpt custom features, saved as a new file, closed it, opened it, then flashed the patched file to the car. it fires and dies after a couple seconds. SD is set to maf only, but I suspect that the patch is trying to read Ve for some reason even though it's set to maf only. I will reflash the stock hpt file tomorrow morning and have the answer of "will it run" on an unpatched file then. If you could help me fix the patched file that would be awesome as I don't currently want SD, but would like the other features like flex to work. Please Help me out here! I have several cars to do and Im using myself as a test mule before I pull the trigger on using hpt for the others!
Sorry for such a long post, but it looks like you are actually willing to help fix issues after reading other posts you have helped on!
Thanks,
Ben
I'll take a look at the ticket, that seems strange as AZ1G401V is the exact file I used to do all the initial testing on and made sure everything worked properly. We'll figure out what's going onQuote:

Thanks,

Any luck on this yet?Quote:

The sd patch is what causes the car not to start. I just dont see why. No other changes betweent the base file and the patched file except the custom features patch. Also it says to only do a full reflash one time when applying the patch, but it seems thats the ONLY option for reflash as the drop down box im the write menu says full write or do not write. Am I missing something here?
It's definitely not trying to use the SD tables, it's still in MAF mode. I believe the flex fuel tables are what is messing with it somehow, the OEM tables get overriden to the "Flex Fuel -> Low Ethanol Content" Tables. I.e. making a change to your cranking fuel tables, injector scalar, boost, or lambda/AFR tables will do nothing, you have to make the change in the low ethanol content tables. Try using those to fix your issue, if you don't want flex and it's still bothering you I can remove the feature and investigate further what's going on. This hasn't been an issue on the test vehicle, which like i said runs the exact same file as yoursQuote:

I need it to have the flex ability in the near future as I have all the flex parts, just not installed yet. Im trying to get the software to cooperate before the flex install and once good there id be ready to install and tune flex fuel. So disabling that wont really work for me.Quote:

Now, with that being said about scalar and cranking ipw being overwritten, IN ORDER TO GET THE CAR TO START AND RUN DO THE FOLLOWING!
REGARDLESS of flex sensor and accompanying parts being installed, YOU MUST ENABLE FLEX FUEL in the map to get the car to start because as stated above, the oem maps have been overwritten and if flex is disabled, the car has NO injector scalar, cranking ipw, boost, or lambda/afr tables to reference and doesnt know how to go about things properly.
I do not currently have flex fuel parts installed on my car so I didnt see why I would need to enable the flex maps, but after reading the reply, I rrealized that it will have to be enabled for the ecu to even know how to run the car. Now, will this completely fix the issue for tuning the car while not actually using flex? That im not sure yet, but will report back.
Evan, Please let me know your thoughts here!
Thanks,
Ben
I think you misunderstood, you can still leave the flex fuel mod switch as disabled, which won't enable flex fuel. In fact this is what you should do if you aren't running a flex kit or plan on using the mod. HOWEVER, if flex fuel is disabled, the Low Ethanol tables/scalar are the tables being referenced even when flex is disabled. I realize this is a bit confusing, which is why I'm migrating back to the OEM tables being used. For example, if you want to edit the cranking IPW, instead of editing Crank IPW 1-6 in Fuel -> General -> Startup, you would instead edit the Crank IPW 1-6 tables in Fuel -> Flex Fuel -> Low Ethanol Content (Leaving Flex Mode still as "Disabled"). The logic remains the same, it's just the table gets moved to a different location in the software. Editing the original OEM tables with custom features applied will make no changesQuote:

Changing the scalar or cranking ipw has no effect whatsoever on getting the car to start if flex is disabled on the patched file for my instance at least. Like I litterally patched the file and the car wouldnt start. I then tried changing the mentioned settings and had no effect and no start still. I put it all back to a base patched file and the ONLY change to the patched file was that I turned on flexfuel (tgv left) (my car even still has tgvs at the moment lol) and the car starts as if it has the regular unpatched base file in it. So my question is why does it do that if what your telling me (and what your telling me makes sense. Im not questioning that so I hope you dont take it that way at all!) Should be all I need to do?Quote:

Also, you will need to set the ethanol content sensor scaling to 0 across the board unless you actually are really using the input for E85 concentration level measurement or it will think it sees E content and try to blend the maps. In otherwords, if you scale it across all 0 then E content will always say 0 and it wont use the map blending. I was also having checksum issues and failed flashing, I believe what was causing that was I had changed my base map inj scalar and timing /afr maps outside the flex window. You need to leave any map in the base file that is duplicated in flex maps alone. Make all those changes to the flex low eth maps. The injector base latency and pulse width comp maps in base file can be change because there not duplicated in flex mapping. Let me know if I can help here. I have my car running now and all my AP maps converted obe to it and it succesfully flashes everytime now without checksum errors. Lots of bugs they need to get worked out but im determined to get mine right and hopefully work with hptuners to get things straight in the files and possibly add a few things like af#3 correction tables so you can change to disable af3 learning and also would like to see a voltage scale for tgv right so we can use fuel psi sensor on tgv righr input and rear o2 voltage scale as an input to run WB direct to ecu for logging!Quote:

I see alot of these for tuning and would love to help and benefit by having a better program in the end! I know how the fules and nost of the code works so hopefully I can assist you as well as you assist me!
Thanks,

Was this ever fully resolved?
As far as I can tell HPT has essentially been radio silent throughout this whole launch. I ended up ditching the platform for open source. I had a lot of hope for HPT but they bungled the launch so badly. Even bought a MVPI3 the first week of sale.Quote:
