ClimberDHexMods Posted December 9, 2010 Share Posted December 9, 2010 It's probably best to have a dedicated thread for this tool that was recently discovered--at least within this forum--for interfacing with the 5eat TCU. It's a pain to find the existing discussion on this in other threads. https://www.dropbox.com/s/nbsmh4kok5afn89/FreeSSMinstaller.exe?dl=0 https://www.dropbox.com/s/jo9p7hpxt6brf2z/FreeSSM-1.2.5-windows-qt4-installer.exe?dl=0 ^^^Download This utility connects with your laptop to your TCU via the OBD-II port with a VAG-COM cable. VAG-COM cables can be found on eBay for <$15, and cable software drivers can be found with a little searching, or from the cable seller. FREE SSM allows you to perform a partial or full TCU reset. The first level of reset clears the check engine light (CEL) codes if present, and does whatever else the utility says to you in the warning before you confirm your selection. The second level of reset clears the TCU of all learned values and all CEL codes, which means it will revert to factory shift parameters with a clean slate, and then shift adaptation learning will begin all over again when you drive around. There is a 'proper' re-learning procedure that can be performed by your dealer with a Subaru Select Monitor (SSM). The SSM will tell the driver what to do while driving during the initial learning phase. Little is known about this procedure and whether it is actually necessary for the TCU to command normal, smooth shifting.

ClimberDHexMods Posted December 9, 2010 Author Share Posted December 9, 2010 Edit: It worked for me with Windows 7 64-bit and Vag Com cable. The release notes say it won't work with 64-bit Vista or Windows 7, which I have. They also say it will work with Tactrix 1.3 connectors, but not the 2.0. I have the 2.0. Needless to say I could not connect. Going to try a Vag-Com later and see if that works.

frank_ster Posted December 9, 2010 Share Posted December 9, 2010 so have they found a way to play with it yet ? Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
KyLegacy 2.5GT Posted December 10, 2010 Share Posted December 10, 2010 I have Windows 7 64 bit and a Vag-Com cable and I was actually the first on the forum to get it to work. Its actually pretty simple to get it up and running. As of right now there is only 1 adjustment for the 5EAT and a lot of parameters that can be monitored but not logged. The adjustable value is for the center differential clutch torque but I don't think anybody on here has tried paying around with the values.

Mega Users seabass07 Posted December 10, 2010 Mega Users Share Posted December 10, 2010 It definitely works with windows 7 32 bit and a vag com. We need to figure out a way to log with it because max values are worthless most of the time. Lots of parameters! 5 minutes with it convinced me that I NEED a transmission cooler for stage 1 with barely any more boost than stock below 3500 rpm. Excellent tool...just requires someone to look at while you drive. Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted December 10, 2010 Mega Users Share Posted December 10, 2010 If we could log it with load and rpm we could figure out how the tcu uses the requested torque and weighs different numbers out. Link to comment Share on other sites More sharing options...

lieutenantcolumbo Posted December 10, 2010 Share Posted December 10, 2010 where is this info / programs ? I think a most of it is posts in the 5EAT TCU Reverse Engineering thread. Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted December 10, 2010 Author Share Posted December 10, 2010 There is also some discussion in the 5eat tune your line pressure thread. Either way it all gets diluted with all the other posts, so hopefully it can be kept here where it can be followed without much topic interruption or dilution.

fishbone Posted December 13, 2010 Share Posted December 13, 2010 I have not used FreeSSM so far other than just firing it up to see if it works, but ... what is this?? http://developer.berlios.de/dbimage.php?id=4248 Realtime (aka non-permanent like base) line pressure adjustments? It shows a 4EAT though Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted December 13, 2010 Author Share Posted December 13, 2010 There is free software that allows one to make a video recording of their screen. Would be a nice way to record and playback a FreeSSM pull and compare line pressure target readings, sort of. Maybe have RomRaider gauges in the background to keep tabs on what's happening vs FreeSSM.

It shows a 4EAT though It still hasn't gotten there for the 5eat yet. I can't wait until that gets figured out! I can't think of any reason to adjust the pressure on the central diff.

Mega Users seabass07 Posted December 13, 2010 Mega Users Share Posted December 13, 2010 Can romraider be used at the same time as SSM? I'll have to try that later... Link to comment Share on other sites More sharing options...
tangcla Posted February 21, 2011 Share Posted February 21, 2011 Bump for the FreeSSM thread? What *can* be done on the 5EAT, any updates? Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted February 22, 2011 Author Share Posted February 22, 2011 Bump for the FreeSSM thread? What *can* be done on the 5EAT, any updates? Updates for hacking the stock 5eat TCU would be in the other thread. I have used this utility to read and reset trans codes, and you can also use it to reset learning. It can also read a ton of information from the trans' active operation.

elib Posted February 22, 2011 Share Posted February 22, 2011 I know this isn't 5eat related and is OT but it would be cool if they could figure out how to change TPMS settings with this tool. Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted February 22, 2011 Author Share Posted February 22, 2011 Sometimes the Subaru Select Monitor can change that type of thing.

tangcla Posted February 22, 2011 Share Posted February 22, 2011 But the problem is that the alterations are non-permanent, right? Link to comment Share on other sites More sharing options...
elib Posted February 22, 2011 Share Posted February 22, 2011 Ya, you need the "real" SSM tool that the dealers have to change TPMS sensors AFAIK. It would be sweet if these guys could figure out how to do that with this tool. Would save lots of people lots of money! And would save me a 1hr drive to get my TPMS sensors programmed. Stupid tire monkey broke my sensor. They were happy to replace the sensor but it's taken me months to convince them that they can't program my car for it. Now I've gotta go to the closest dealer which isn't that close. Link to comment Share on other sites More sharing options...

Stupid tire monkey broke my sensor. They were happy to replace the sensor but it's taken me months to convince them that they can't program my car for it. Now I've gotta go to the closest dealer which isn't that close. Any tire place should have the tool to read the TPMS code. When I got my winter set with a set of TPMS on them, they woke them up, reflashed the TCU to recognise them and gave me the HEX numbers for free. I bought the ATEQ from tirerack.com for 100.00 and plugged the HEx codes to both sets of tpms senors in. This wil be the first year using it, but form my understanding as long as you have the HEX codes and the sensors are awake, the ATEQ will relash the TCU with the new codes. But lets keep this thread about the 5eat and how we can fix our slow shifting issues, increase line pressure, hold more power, hard shifts, want to get to 5th as fast as possible thread...

fishbone Posted February 25, 2011 Share Posted February 25, 2011 Glad someone revived this thread because I was wondering ... In FreeSSM it seems that non-permanent means the changes are reset upon disconnecting the battery. So I wonder, would altering the line pressure make it, in fact, stick until you lose power? If that were the case then I don't see a significant issue. I will try this once the weather improves. FreeSSM DOES allow one to dick around with line pressure, does it not?

It supposedly does on some 4eats. [CENTER][B][I] Front Limited Slip Racing Differentials for the 5EAT now available for $1895 shipped, please inquire for details!
