LGT 5eat car year?08

IPT VB mod already performed? No

If I have the money then yes Ill happily that amount

Climber is your looking for a 08 VB, if your up to it I can drive to you one weekend

Might be in depending on cost

Looking to buy 1? just for the diff not the rest of the transmission

+1 to what fish said

Bring it to the dealer and see if they can pull any transmission codes. Transmission codes wont always set a check engine light.

I had the 2-3 hard shift, and there was a code for me but no light came on. They made the TCU relearn and now its fine

This is old info on enabling voice control of the navigation system.

Found this on http://www.sb9t.com:

OT does this work the oem navi? I wasnt sure when I read that thread

sorry Ill delete my post and post it there

forgot about that thread considering how new it is, and not subscribed yet

The input clutch connects the input shaft gear assembly to the rear assembly (output shaft) when engaging 4th and 5th. It doesn't appear that the actual gears are failing, just the clutches. It must be a bit weak for extra power. Maybe that is the clutch assembly that some people are adding clutch disks to.

correct people add clutches to the clutch assemblies to hold more power.

Dont know if they make it for Subaru's but theres a company that makes a clutch/steel on 1 piece of steel (if that makes sense) So one side is a clutch and the other side is a steel. This way you can pack almost twice as many clutches/steels in the assembly. Normally its clutch stacked next to a steel

Something like this

I believe it is a combination of both the gears and bands that let go due to the heat caused by the added stressed of WOT shifting at stg2+.

I took a look at the 08 transmission and theres no bands just pistons/clutches. The brakes are also piston/clutches

Input Clutch

Direct Clutch

Reverse Brake

Forward Brake

Low Coast Brake

What happens is the Brakes let go and the brakes restricts reverse rotation of sun gear or lock sun gear

I have some understanding of auto trans, I took them completely apart and put them back together before

Does the 07 have the 1st or 2nd version of the VB/TCU anyone know? I guess the easiest way to test is does it have downshift rev match...

Needed information for Transgo, post answer here linky

I upped my requested torque from 350 to 498 (max is 500), only upped the requested torque for S#

running OTS Cobb ACN Stage 1, w/ lightweight crank pulley

The other day I was on freeway to freeway on ramp, shifted to S#, manual shifted to 2nd gear, right after it rev matched I floored it and it seemed liked it free reved - was not pulling in 2nd. I quickly shifted to 3rd and was fine. I dont know what happened and didnt look at rpms/boost but knew I was going about 43mph. I know what 40mph in 2nd gear feels like

Maybe it didnt catch 2nd gear or hopefully was not slipping in 2nd

Im not concerned yet, just letting you guys know what happened

Any 2007 5EAT owners reading this? If so, does your car up-shift rev-match?

It shouldnt upshift rev match, just downshift rev match if it has downshift rev match

little stretch look on a 9.5 would be 245-255

just confirming fit on struts and lowering springs? not coilovers? opie is using struts and lowering springs

Thanks

I am taking notes for future

Whats the offset, I think theres 2 offsets for this rim size??

Oh most definitely.

About what tire size would you guess you can run, possible to have very little stretch tire look?, most of the guys are running coilovers with these rims thats why im asking

Thanks

Love the look!!

Did you try manually shifting the gears? I don't even mind the stock shifting for regular driving, as long as it would "SHIFT_RIGHT_(*&@#$_NOW" when I hit up/down, instead of waiting for a consensus from the characters in Herman's Head..

I always drive in manual mode. There is still the delay when you tell it to shift to when it shifts. But what I noticed from factory it downshifts nearly instantly when I tell it to

Thanks. Running with Tein S-Tech w/KYB GR2 Shocks.

Do you think you can run wider tires with your suspension setup without going coilovers? Im asking cause Im looking into Grids in the future

So how does this affect us guys with the IPT valve body?

There's not much to say yet from tuning the tcu or the Accessport Req Torque changing. I do not have a VB mod. The hypothesis is increase even more line pressure then the VB mod (for those who have it) for more clamping power without spening $5k for full trans build. But don't expect this to hold 500hp with just tcu mod and VB Mod

Nice start!!! I adjusted the top row of the throttle table, the one that is the table header. It is scaled up by the same % the RTq map is scaled up. You may have found something else since you did not adjust the accelerator map, which is that the manual states that throttle plate position and accelerator position are also pulled from the ecu to determine trans behavior. I wish I could work on this side by side with you, but I am still getting tuned, and am chasing a pesky air leak. Hopefully we can figure out exactly where to add pressure to benefit us with a greater clamping safety margin, without sacrificing comfort when it is not needed. I'm sure there is sn optimal way to tune these accelerator tables for trans behavior.

Can u post The accel table u also adjusted. I'm scared to adjust it too much. Like having too much of a range:lol newb at tuning

EDIT: Just looked, Requested Torque: the top row is Accel Position. Theres another chart for Throttle Angles and I was going to adjust that. I guess I wasnt paying much attention. And was thinking Throttle Angle is the same as Accel Position. I dont think Ill need to adjust Accel Position Do I?

So adjusting the Req Torque did make a difference. When I tested earlier I was doing WOT runs, today I was just doing city driving. There was not a difference in shifting, but there was more 'resistance' while driving. From what I understand for more 'resistance' is the lockup is gradual, not on/off. So adding more line pressure added more lock up at a lower rpm. I only changed S#, so when I changed to S the resistance was gone/decreased, and shifted back to S# resistance I can feel some resistance.

I did have a 2-3 upshift bang and that might have gotten a bit worse at higher rpms but I dont really know. What I do know if downshifting from 2-1 at high rpm it hit 1st pretty hard after rev matching, this is around 32mph

My concern now is if we have a pressure plate for lockup, will the increase line pressure at lower rpm and higher lockup wear the pressure plate more? Or whatever part is for lockup?

I did not adjust the Throttle Angles

Fishbone. There's another table that says Throttle Angle iirc. It's the last table/picture I posted on the previous page.Req Torque on top row and your changing Throttle Angle. Did u change anything there? If u did can u post it also?

Thanks

EDIT: I read it earlier on my phone. Its just a OTS Stage 2, nothing else done. Ill compare a Stage 2 to a Stage 1 and see any diff. There is no diff in Cobb OTS Stage 1 91, 93, ACN 91

My Torque table is maxed out at 400, again I can't tell if it really makes that much of a difference.

Can you post a pic of the chart so I know what to look at

Thanks

Think I understand Ill need to adjust the Req Torque number in the second chart. No rush I can wait to tomorrow. Its not like its needs to be done right now

All 3 charts (Trottle Angles A,B,C @ 333 its all 84.00) on their map

ClimberD said to adjust down Throttle Angle, how much/should I adjust. Down would be less numbers but letting you guys know it goes up to 100. I dont know/cannot add more columns. So do I need to adjust 333 to 490:confused: Orig Map went over 333 in Req Torque so I assume ill be fine:confused:

BTW Si-Drive, all Req Torque chart is different in the 3 modes, so is also Throttle Angle chart

I increased Req Torque from 350 to 490 (look at earlier chart)

This map is Cobb Stage 1 ACN91

1st pic what I adjusted, made it 490 @ 100 Accel Position

2nd pic what I should also adjust according to ClimberD

That must be nice

Yea I'm one of the few who really loves the 5eat:wub: but ive never really driven a manual so no experience. And I got lucky cause 07/08 they changed the tcu to make it better:)

Aside from smoothness, any reduction of shift time noticed? Even with the IPT VB I notice it still takes a long time to shift at higher RPMs.

I dont think there was a reduction in shift time. Plus I have an 08 and they reduced the shift time anyways
