whitrzac Posted May 14, 2015 Share Posted May 14, 2015 We thought that about the 5th gen models, until we found another table which sets maximum RT by rpm. Once you raise the limits in there, it's possible to raise RT all the way to 512. Changing RT helps a lot, and seems to increase line pressure and shift points slightly as well. Changing CT is less obvious but in logs you can see the time taken to shift drops significantly, and revs drop immediately and no 'floating' around. Subjectively the shifts are firmer. YMMV and all that. Link or is that information not public? I remember reading somewhere that there's a max 'value' for the RT programed somewhere in the ecu can be changed, but even after adjusting that it still only operated to 408. The TB didn't open all the way. I go googling late at night, I come back with more knowledge, but no idea where it came from:lol: Link to comment Share on other sites More sharing options...
fahr_side Posted May 14, 2015 Share Posted May 14, 2015 We were getting stuck around 400RT but then the table that capped it was defined. Throttle position is not determined only RT, it's also related to the requested torque base. Unless the ratio tables are screwed up, RT being higher than the requested torque base will get you 100% throttle plate angle. You can read up on this at Romraider.

fishbone Posted May 20, 2015 Share Posted May 20, 2015 Sounds like it's part of the valve body. If so, you may not be able to source it as an independent part. You may be stuck having to buy the whole valve body. http://www.car-part.com Link to comment Share on other sites More sharing options...
FLlegacy Posted May 21, 2015 Share Posted May 21, 2015 (edited) If you can find a subaru part number there's probably a vendor that carries them somewhere. Have you searched google? A quick one I did turned up a place called cobra transmission. But you had to call for prices. Edited May 21, 2015 by FLlegacy Link to comment Share on other sites More sharing options...

west_minist Posted June 13, 2015 Share Posted June 13, 2015 (edited) So you actually can tune up the 5EAT Tcu? Its not really tuning up the tcu. The ecu based on the programming logic between the ECU & TCU, tells the TCU how much torque to apply to the clutches - based on many inputs. In respect to the dbw table (request torque), if you advance this and adjust the Target Throttle position table (which takes the input request torque from the accelerator table) you can make the TCU behave the way you want. So in essence, balancing the DBW RT and the Engine Request TQ, then you can have the wonderful 5EAT work the way you want. I am hoping within 2 months, I can post the results of a car I will be working on that will be a 10sec car using the 5EAT - which will be built to handle the torque. Take a look here with some of the 5EAT shifting:- https://www.youtube.com/user/westminist/videos and compare it to your 5EAT. I would post more on this but all of my data is based on feedback which I get and thats promo. I would beg for more vids but its against the law in many countries to drive and hold a camera For further knowledge to understand how some ems affects this in TCU cars, view here. I find it very good and review other EMS, this company seems to do it well, but the technical knowledge impart is helpful for the community to understand. If there are others, you can post. https://www.youtube.com/watch?v=COs5lHcpXNg https://www.youtube.com/watch?v=zTDWctNFzTs Edited June 13, 2015 by west_minist Link to comment Share on other sites More sharing options...

Center diff bearings maybe? i doubt it be enter diff stuff, because it would be banging when you turn. could be your drive shaft u joints. or something else is funky.

imprezkid Posted June 18, 2015 Share Posted June 18, 2015 Another good example is when you put it in park on a slight slope, it will make a loud click. Same for going into drive. U-joints do make sense, I'll check them. Are the diff bushings an upgrade on the 08 style Trans as well? The vf52 puts the 5eat to the test and I'm thinking about switching to e85 soon.

MTBwrench Posted June 19, 2015 Share Posted June 19, 2015 So... does anyone have experience with the Rallitek 5EAT trans mount, in particular the harder version?

starionesir Posted June 20, 2015 Share Posted June 20, 2015 There is a little bit more noise transferred into the cabin. My car is far from stock so its hard to hear all the noises over the exhaust but I did notice a slight increase in noise and a little vibration. On a stock exhaust car you may notice it more. I think it was worth the noise. It tightened up the feel of the transmission a good bit. Link to comment Share on other sites More sharing options...

I think it was worth the noise. It tightened up the feel of the transmission a good bit. So, that means I should probably sort out my rough idle issue first before I go and transfer even more drivetrain movement into the chassis. But once that's done, I'll definitely be getting one of these! MTBwrench's Stage 3 5EAT #racewagon 266awhp/255awtq @17.5psi, Tuned By Graham of Boosted Performance Everyone knows what I taste like.
