sulk Posted December 4, 2010 Share Posted December 4, 2010 get an open source tune. If you look in the tuning section, youll see we have a thread there going over whats needed to tune a 2.5i. Basically you need a vagcom cable (dealextreme, ebay), and a laptop with the appropriate software. Youll also have to check if your ecu is defined, so you can get a tune. If not youll have to dump it, and then post it on RR and hopefully someone will define it for you. After that, you have to choose a tuner. A bunch of us went with PhatBotti on NASIOC, but theres been so many hickups, and delays..Infamous here on LGT also does tunes for 25$ more (125), but I dont know how many/if any NA engines hes tuned. Do you have an auto or manual? The DBW tables are one of the things that get changed, and def make the car drive a LOT better. I have an auto, if you want to see the diff just let me know. Kinda busy, but this weekend but i have some spare time next week (still wanna hear your UEL ;p ) Also, dont know if 94 is best thing to do. I hear its getting scarcer in the GTA, maybe 91 would be more ideal. Also dunno how much gains youd get on 94 with an NA. I'm getting a 89 tune just cause its more reasonable, and not too much more expensive then 87. Link to comment Share on other sites More sharing options...
Vam Posted December 4, 2010 Author Share Posted December 4, 2010 hey man I'd love to meet up and talk about this kinda stuff sometime soon, Its a 5 spd, and I have sources for 94 everywhere I go, thats actually what I use now Link to comment Share on other sites More sharing options...
sulk Posted December 4, 2010 Share Posted December 4, 2010 Maybe at one of the meets next week? Tues is downtown Wed is oakville Thurs is sauga They all start around 8-9~ I havn't been out to one in a while, but I know they're still pretty busy.

sulk Posted December 8, 2010 Share Posted December 8, 2010 Oakville tommorow night? or thurs for the sauga meet? Either day I should be good The sauga ones are busier/more people, and oakville tends to have a bit of a smaller turnout. Link to comment Share on other sites More sharing options...
sk_leb Posted December 8, 2010 Share Posted December 8, 2010 Hey - what will an 89 tune on a stock 09 2.5i do? Or is tuning just to modify the stock ecu to compensate for your mods? Link to comment Share on other sites More sharing options...
NORULZleggy Posted December 10, 2010 Share Posted December 10, 2010 I would not tune it man. Save your money for tires, and suspension, and maybe some looks. I am old school and N/A just nets no good gain. I run 87 octane and get great gas and have had no problem with the car. Just seems if you wanted more power you should have waited and got an LGT or used WRX. Link to comment Share on other sites More sharing options...

Like you said - if I wanted a "powerful" car I would have gotten a LGT. I just wasn't sure what a tune did - and if it would be necessary to improve driving conditions.

NORULZleggy Posted December 10, 2010 Share Posted December 10, 2010 Most time it is not about power and speed, and if you can drag them to a back road and your suspension is tight and you have good tires you can out drive them. Link to comment Share on other sites More sharing options...

You can tune to better use 87 or step up to 93 BUT you are right I would only tune to correct fueling with header or a turbo kit. They say or claimed the AP OTS maps gave good results but more so in the throttle linearity through the RPMs. You could tune for things like NO P0420 if you get UELs, Tune out the RPM holder btwn shifts, tip in, and torque ref table relations BUT you only have but so much HP to work with and that aint much Link to comment Share on other sites More sharing options...
sulk Posted December 10, 2010 Share Posted December 10, 2010 For me the tune has been worth it so far, if anything just for the fixed DBW tables. It's a night and day difference between stock and tuned. Also getting a throttle controller up here would involve customs, and I'd rather not be fiddling with a controller when driving. So for me it was either; throttle controller or tune. I chose tune, and since I have some aftermarket stuff hopefully I'll see some gains along with proper DBW table.

Infamous1 Posted December 10, 2010 Share Posted December 10, 2010 N/A or not there is always value in tuning, assuming done properly. Link to comment Share on other sites More sharing options...
GEE-OTTO Posted December 14, 2010 Share Posted December 14, 2010 Yes there is but our stock ECU/Tunes dont take timing well AT ALL even in 1 or 1/2 degree advances to lay down a baseline for observation. I would tune to improve the 87 trim and throttle response personally. Link to comment Share on other sites More sharing options...
Infamous1 Posted December 14, 2010 Share Posted December 14, 2010 Actually a proper tune could be removing timing as well for a consistant and safe running vehicle. Link to comment Share on other sites More sharing options...
roll_tide Posted March 3, 2011 Share Posted March 3, 2011 I guess I'm reviving this thread BUT I finally have the cash so why not... So the consensus is that a tune wouldn't do that much for a 2.5i? but it would help fix some of the throttle control issues? @infamous, If it would even be noticeable, what stage tune would you suggest for an all stock 2.5i? and any upgrades to go with it Link to comment Share on other sites More sharing options...
sulk Posted March 3, 2011 Share Posted March 3, 2011 Our "Stages" are different than GT, so it is hard to compare. I'm still in the process of tuning my car, kinda stopped because of the weather, but the improvements over stock are worth it imo. I didnt want a throttle controller(dont like to fiddle with stuff while driving), and the change in the DBW tables has helped a lot. Tune is cheaper, and possibly more effective than a dbw controller, so that's why I went that route. I dont think too many people on LGT have tuned a somewhat stock 2.5i, most people have done e85 tunes, so I dont think there are any solid numbers out there.

roll_tide Posted March 3, 2011 Share Posted March 3, 2011 What all would be required for an e85 tune then? Definitely interested, just want to do some research before jumping in Link to comment Share on other sites More sharing options...
cybonic Posted March 3, 2011 Share Posted March 3, 2011 my ignition timing @ 110-120km/h is ard 40-41. but we really must wot to achieve the peak power Link to comment Share on other sites More sharing options...

Definitely interested, just want to do some research before jumping in here a thread with a bunch of info, although I guess it depends on the availability and access to e85.

GEE-OTTO Posted March 8, 2011 Share Posted March 8, 2011 See I want a tune now BUT there are no definitions for a 08 2.5i 5MT only a 4EAT WTF? Anyhow I have my exhaust squared up i wan a throttle table adjust for linearity and maybe the rev holder above 4K done away with. Not to mention I have to use a Tactrix 2.0 cable $160 where as you could use a VAG-COM ~$8-$20 via eBay Link to comment Share on other sites More sharing options...
