What changes do you have in mind or have done to the car thus far? Arent you doing a UP/DP or something similar? OS tune done by the right tuner is always a good choice vs an Off-The-Shelf tune aimed at the owner having a specific set of mods

I personally have been down this route went OS over COBB AP because I have a 2.5i and only wanted to smooth out the throttle tip in tables, torque request values, hill holder, rolling RPMS, 93OCT and UEL headers. While COBB has an AP for my car and maps I was able to get a Tactrix Cable and OS tune for cheaper.

You have a turbo vehicle so much more at stake as far as tweaking the engine, etc but the right tuner can work wonders. You are in Culpepper there is a good shop in Winchester (the name alludes me dammit) and then there is Mach V here in Sterling that can help you out with your tuning needs.

Im sure many of the members have been in your shoes and can help you make an informed choice!

With a good tuner and time, opensource is a very good way to go. It also depends on your mods and how often you will be changing parts out. Off-the-shelf tunes are good in the aspect it will get you somewhat close to where you need to be but every car is different and mods will effect every car differently.

I am currently tuned open sourced right now by a local tuner but I will be picking up a Accessport not for the off the shelf tunes, but I will have 4 different maps for my car and it will be easier for me to put the tunes in the AP and flash my ecu than carrying around my laptop everywhere. I will have a Gas tune, E85 tune, and 2 gas-e85 tunes. One for when I'm switching from gas to e85 and one for when I'm switching back. E85 is very prominent where I live but when I travel will switch back over to gas.

It sounds like you are in an area with some good reputable shops so talking to them also can get you pointed in the right direction.

I had a cobb ap OTS stage 2. It left alot on the table and had quite a bit of knock. Now I am finishing my infamous tune and haven't even looked back. The infamous tune is so much better than the cobb ots tunes.

On my 05 LGT 5eat,Im going BNR 16,and turbo back. Found a decent deal on a Cobb APv2 however if Im just gonna have to tune it afterwards anyway then maybe opensource is the way to go..

Is it as painless as most say it is?

I have only e-tuned twice but I am sooo glad I did as opposed to going with an AP. You will also learn a lot of valuable information and processes while going open source. It really is a better option.

I like the cobb for the functionality of it all... You can have your car protuned via a cobb AP. Etunes are also a bit easier, and the options appear more plentiful with an AP.

The AP interface is easy to use... Fits in your glove box... and has a boat load of other functions on it. You can use it as a boost gauge, data log tool, code reader/clearer... etc, etc.

I prefer an AP over having to lug around a laptop personally.

Pros of AP:
1) small and convenient

2) "realtime" map loading - valet, economy, 91 octane, etc. maps that are available off the shelf.

3) on the fly tuning if you have a laptop with their accesstuner software. connect your laptop, and i think you can make a tweak to the realtime map immediately and see what happens. no need to reflash.

Cons of AP:
1) price - $400+ for a used one. $500+ for a new one. tactrix is about $100-150, vagcom is $10.

2) smaller screen, can't display as much on the screen. with RR you can display a buttload of parameters on the screen at once.

3) larger logging interval. RR recently introduced a function called "fast poll" which allows me to log about 18 different parameters with a logging interval of about 98ms. AP can't even approach this. i think their interval is something like 200+ with 8 parameters.

4) doesn't have access to as many different parameters as RR. opensource tuning has a lot of support from the community. AP support is really... only from Cobb vendors/tuners (infamous will tune for AP)

5) as bmx said, RR has a ton of customization available to you.
So there you go.

^ That 'review' certainly leans towards someone that chooses RR over an AP.

I like opensource for my '05 because it's practically free. $12 for a cable from amazon and your done if you have a laptop running windows already. I'm custom tuned for $162 vs and AP off-the-shelf tune for $595--hard to argue that. If you have an 07+, the price difference is a fair bit less, but opensource is still cheaper.

At the end of the day, you are really probably best off to pick your tuner first and then find out what THEY want you to use. Use whatever they are more comfortable with if they have a preference.

I prefer the OS. Why buy a ap for 500 bucks, when you can buy a laptop for that cost, and a really nice one at that? You can use the laptop for anything, searching lgt forum while your working on car, do school work, work work, look at porn... Granted the ap has some degree of user friendliness. But once your dialed in on a tune, why would you still need it? The cost for a custom ap map is the same as an os map... I can only imagine the ap being useful if you do not plan to get an etune or tune from a shop, or maybe you live 3-4 hours from any decent tuner. But I think the AP was king when the lgts first came out, but it looks like OS is by far the more cost effective, bang for the buck option.

jasejase 01-23-2013 02:03 PM

^ True, unless your like many people, who already have a desktop computer, and aren't in the mood to spend another $500 on a laptop.

Eh, i like my AP (and i have a laptop, netbook, and a desktop lol). Sits in my car. It's there when i need it, or want to use it. It clips onto my vent too, so im no struggling with it on my passenger seat or lap during a log.

No right or wrong answer here, but there are strong points for either.

jasejase 01-23-2013 02:04 PM

... and you can usually find a used AP for $300-350 ish

Tehnation 01-23-2013 02:09 PM

Do the math!

OS tune, 150 dollars for tune, 15 dollars for vag-com cable for 05-06 ithink, or 100 for tactrix for later than 06, but your an 05 so you can get away with a cheap cable. so basically if you have a laptop you can get a superior tune over an off the shelf generic for like 500-165=335 less than an ap. OS is better and cheaper...

You can buy a laptop for the same price as AP. Thats what made me go OS.

jasejase 01-23-2013 02:40 PM

I never said that the AP was cheaper.

The 'better' part is subjective. I can appreciate both sides of the arguement. Not saying you made the wrong choice here.

Keep in mind that having an AP, doesnt equate to having an off the shelf generic tune. That's only true if you own an AP, AND have an off the shelf generic tune. One does not equal the other.

I've had three custom tunes with my AP. Two out of three of those, were with tuners that were AP only.
