FreeSSM - Complete access to your ECM and TCU - Page 2 - Subaru Outback

Nice circuit hack

I may have to try that.

I am still wondering if something can be adjusted in the ECU to eliminate the P0420 problem.

Considering that that P0420 problem could be fixed with a $5.00 anti-fouler or $4.00 in electronic components, $15.00 seems fair to be be able to fix it directly in the ECU with FreeSSM

Nope sorry, there isn't an option for that in FreeSSM.

I have to check out this FreeSSM thing. I just got the Ultragauge and its pretty cool. But I want to change the TCU programming to hold 4th gear longer and prevent upshifts into third until I go past 50% throttle opening...

Hopefully the software and USB drivers runs on Windows 7 64-bit... otherwise I gotta dig up a 32-bit Windows XP laptop...

ntippet · 10-20-2011, 04:59 PM

It runs on Windows 7 64bit.
Already tested that.

Seabass · 10-20-2011, 05:14 PM

And ubuntu and win 7 32 bit.

I'm not sure it will allow you to alter shift points. I know on mine, I can't really mess with anything in the transmission, just the transfer clutch. I'm really mad that you can up the line pressure for shifts on your transmission. That's the only thing keeping me from more power. I don't have that option!

Muahahahaha!!!!
Honestly I am NOT going to touch them.
My transmission works just fine

There is 1 parameter I wish was there though:
Torque converter clutch disengagement correction.
Something based on engine load or throttle %, its tough to get it to disengage and hold 4th gear for hills.
Usually it just jumps all the way down to 3rd.

Tell me about it. I'm seriously thinking of wiring in a control switch for the tcc. Id prefer to take control of it completely. I think id save a bunch on gas around town. A 3500 rpm stall speed is horrible for city mpg. Just have to remember to disengage before stopping...

ntippet · 10-20-2011, 06:13 PM

Yeah I am thinking about doing that too.
Maybe modifying the gear selector & mounting a switch is under the ring or pointer finger.

But then would have to fool the TCU in thinking everything is still normal.
Would probably throw codes. P0741, 77 & others.

Seabass · 10-20-2011, 06:16 PM

I can live with a trans code as long as it doesn't put into some sort of limp mode.

Seabass · 10-20-2011, 06:18 PM

I was thinking about putting a button on the steering wheel next to the gear selector buttons. Id have to have an auto mode for the wife though.
