Need sum help getting my 05 wrx tuned right
Hey guys ....i need sum help! so any help is appriciated.
i just switch over from an acura rsx..and subbie tuning is all new and different to me. I got a 05 wrx....with an automatic trany an i just put the $1.98 hose cupler (1/8 to 3/16) in to speed up boost as i read on this forum and a gp moto intercooler hose kit. And i reset the ecu by disconnecting the neg. batt. term. and i did this will the car was cold. Does it matter if the car is warm or cold? Does it matter how i drive after restting? Im just scared that i might mess something up... Because i took it for a ride after installing hose kit and resetting ecu and i noticed that it shifts into 2nd gear a lot harder then it use to. I also read on this forum that i can advance the learning of the ecu by resetting the ecu warm ...take it on a road .. keep it in 3rd gear at 2600 in boost for 5-10 sec. and this will also boost HP. gain...does anyone know if this will work in an automatic? Or will it damage anything Does anyone know if the IC hose kit would void the warrenty? THANK YOU ..in advance to anyone who helps me out!!! i would just hate to mess thing up over my ignoance -MIke

There are very few things that will void your warranty and IC hoses isn't one of them. Search in the warranty forum for what will void your warranty. IC hoses can be used to deny warranty service. There's a difference and you best learn it in the warranty forum. Take that crappy 3/16ths off of your car as it's 100% worthless and will cause nothing but problems. Welcome to the Subaru world, but remember to reasearch twice, modify once. |

http://forums.nasioc.com/forums/showthread.php?t=302047 Suba-Rex - the reset trick is helpful, but the most important thing to do right now is break in your WRX properly. There is lots of time for mods. I myself would skip the 3/16ths mod. As the car is breaking in, spend your time researching options. How much power do you want? Most of the power enhancements out there for the manual work for the 4EAT. As for the warranty, thereotically anything you do to the car that causes a part to break will result in that particular part not being covered. Most of us have gotten comfortable with modding these cars, though. Have fun. If you want specific 4EAT examples, check out Jorge's site at projectwrx.com. Feel free to PM me if you have automatic questions as well. -- scooter VF-34'ed 4EAT |

What to do next really depends on what your target hp level is. But there are some easy places to start, with respect to staged power packages out there (hp for 93 octane): 260 hp: engine management (EM) 285 hp: EM, plus underdrive pulley and up-pipe (UP) 310 hp: EM, UP, plus turbo back exhaust (TBE) 350 hp: EM, UP, TBE, VF-30/34 turbo, STi pinks, Walbro fuel pump There are other turbos and other approaches to horse power levels. Once you start approaching 300 hp, you need to think about a transmission cooler. You should put a tranny temp gauge now, as the 4EAT is very robust, but heat is its Achilles' heel. Others on this board would recommend putting the cooler in as soon as possible. Also consider switching to synthetic ATF. |

hey i appriciate all help.....
One question that wasnt answered..was Does it matter if the car is hot or cold when resetting the ecu and should i reset it when i replace the stock 1/8 hose cupler? And advancing the ecu learning ...how and WOULD it benifit me? Im not sure what my next step should be...i found this in the forum about the AccessPort..posted by JhoneR... is there any truth to this? Should this be my first step or should i work on getting a better exhaust, DP and a UP AccessPort ($600) is IMHO the way to go as far as engine management for the untrained tuner because it is easily adaptable to your new mods as you go on, is invisible to the dealer, and doesn't involve cutting any wires. Basically, you just plug the thing into the port under you steering wheel, download maps from the Cobb website based on your mods, and load them onto your ECU. There really isn't much of a comparison, although simply reflashing the ECU with for example ECUTek each time to account for your new mods will work but gets expensive and means you have to drive somewhere to get it done rather than just downloading a new map. UTEC is OK but is more expensive and not as easy to work with for the untrained. Old Unichips (now about $200-300) will give you a cheap 30HP or so, but are not widely supported anymore and are therefore not easy to upgrade. Accessport on a stock WRX will add ~30HP and will even out your torque curve while at the same time giving you more peak HP (AND you don't have to mess with the FUN of tricking your HAL 9000-like ECU). |

your transmission is electronically controlled by your t.c.m. along with your e.c.m. when you reset these two computers by unplugging the battery they will have to re adapt to controlling the transmission, the shifting should get back to normal in a few days of driving.
