whitrzac Posted August 17, 2015 Share Posted August 17, 2015 Has anyone noticed that the car is 'faster' when locked in a gear manually vs. letting the TCU figure it out? Its especially noticeable in higher (4/5) gears. Link to comment Share on other sites More sharing options...

frank_ster Posted August 17, 2015 Share Posted August 17, 2015 Has anyone noticed that the car is 'faster' when locked in a gear manually vs. letting the TCU figure it out? Its especially noticeable in higher (4/5) gears. Feels faster.. It's just because the tcc is engaged and there is direct connection from engine to wheels. But even in auto mode it will lock up by its self. 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...
west_minist Posted August 17, 2015 Share Posted August 17, 2015 (edited) Here is a little extract from the guy I told the community about. Awaiting vids. But it shows you if can take a little time to tweak, you can achieve some changes that can be beneficial. My main interest is to get her behaving close to a manual as much as possible. http://www.xtremeracingtuning.com/forum/viewtopic.php?f=40&t=582 .................... Driving in the automatic mode is now enjoyable as the car does not struggle in 5th gear anymore, she downshifts super fast and always when i need just a lil extra power when passing/overtaking cars or climbing hills. In Full automatic Sport mode or Sport Sharp # mode, both modes feel like you are in the manual tiptronic mode with how the power is delivered in throttle response. Before tuning when i would give it gas, it would take a few seconds for the power to be delivered and i could actually start feeling/Speeding up, but now as soon as i give it gas, she just wants to go! Super peppy from Ed's tuning of the TCU, the DBW system has been fully adjusted and now it feels like theres power on demand, it an awsome feeling! No more struggling up hills or struggling for the auto tranny to downshift into 4th/3rd. Before when i would want the car to downshift in full auto mode, you would have the slam the pedal down to get it to downshift for passing/hill climbing...now you barely have to give it any gas for it to downshift to 4th! The bogged down feeling i used to have is gone now that Ed has tuned the TCU! One other thing i noticed with the TCU tuning, when i would red line any gear...between 6000-6700rpm would take really long and it would almost struggle to fully redline to shift gears...now it just flys throughout the WHOLE rpm range,especially at the top of the rpm range it doesnt stall out or struggle to pull thru to redline for gear shifting. Everything ed has done with the TCU has been above and beyond my expectations, Shifting is smoother & faster than before! Videos will be posted soon of how she flys!! Videos On another note frank_ster, I started breaking down the 5EAT operations (through TCU logging) like what you did for EMS operation. Chatting with Syvecs now for integration for the car. We are expecting to run 600+whp. Just hoping it works out financially manageable. Edited August 22, 2015 by west_minist Link to comment Share on other sites More sharing options...
whitrzac Posted August 17, 2015 Share Posted August 17, 2015 I've read about that guy. Personally I think he's full of it. He might have found another ECU table relating to the AT, but he still doesn't have access to the TCU. I have a hexmod VB and diff bushings...

west_minist Posted August 17, 2015 Share Posted August 17, 2015 Who do you refer too? If you do reference me, I have never stated any access too or tuning of the TCU, except affecting the dbw and engine request torque tables. Link to comment Share on other sites More sharing options...
west_minist Posted August 17, 2015 Share Posted August 17, 2015 MAF scaling affects the Calculated Engine Torque table as it alters engine load Cylinder fill table(essentially a VE table) with the calculated engine torque and the existing defined DBW tables will be the difference between getting the trans to perform like it should Matt it make more sense for any tune to dial in the maf as best as their could related to proper fuel and then make changes. It can be done and take time. Link to comment Share on other sites More sharing options...
whitrzac Posted August 18, 2015 Share Posted August 18, 2015 Next question. Sometimes the car 'forgets' to shift out of first and hits redline at 7200rpm. It only happens when accelerating from a stop at WOT. It doesn't happen every time, maybe 2% of the time it does. Any ideas? Link to comment Share on other sites More sharing options...
RooTBeeR Posted August 18, 2015 Share Posted August 18, 2015 (edited) Yeah, I had that crap happen a few times, bone stock everything.

fishbone Posted August 19, 2015 Share Posted August 19, 2015 It's more or less normal. As in, it has been reported here by many different owners. I am guessing you are not stock? Basically the transmision doesn't respond quick enough for how fast the car revs up. Link to comment Share on other sites More sharing options...

ben64 Posted September 3, 2015 Share Posted September 3, 2015 Hi guys, When the car is cold and when I pass to D mode the car move forward "stronger" than when the car have made few kilometers. Is it normal or a bad sign of the oil gear box need to be changed. When the car is cold and for example when I'm at a stop the car seem to be in pain to not move forward ...

RooTBeeR Posted September 3, 2015 Share Posted September 3, 2015 On a cold start, the idle is higher to get the engine to operating temps quicker. Higher idle will cause it to go into gear a bit more rough.

ben64 Posted September 3, 2015 Share Posted September 3, 2015 ok thanks I had not seen the was RPMs higher. Another small question : the gear box oil is the same for the all the transmission because I 've just bought mine and want to make a complete service as the former owner was not aware of the last service for everything ... but good price and seems to works good ! There is just the engine oil and gearbox oil to change or a third one ? Link to comment Share on other sites More sharing options...

frank_ster Posted September 3, 2015 Share Posted September 3, 2015 front and rear difs use gear oils. the trans use atf the engine uses engine oil .. also keep in mind the auto trans mission has two dipsticks, the one on the right ( passenger side on left hand drive cars is for the front differential oil level. there is another dipstick on the driver side ( left ) under the intercooler ( difficult to see) for the automatic transmission fluid. some people have mistaken these two and drained the front diff and then added gear oil into the auto transmission resulting in burned front diff and then burned the auto trans because gear oil is bad for auto trans.
