    Yeah, there's no mention of it in the map notes.

    How did you find the adjustment to the linear pedal response? Do you find that you have to stomp on the gas to get the same effect as before? I'm tempted by a protune with some kind of middle ground if I can choose those parameters. Either way, I don't find the stock map to be very smooth so it needs a change.

    No its just much more predictable....not surging like stock and much better top end than before

    I tried a newly flashed car last night (91 map) and found that it is indeed linear, but there's no power unless you are giving it around 80% gas. That car probably has to go through a relearn so it could be too early to say for sure, but if the response stays that way then I will probably look for some kind of middle ground. My last Cobb stage 1 ('08) wasn't great at my altitude so I'll probably have to get a protune anyway (back then Perrin made a better map for me, night & day difference).

    Huitt06, I tried this some more today and don't really much change between 20% and 80% gas. It feels uneven like before, but in the opposite way. Did you find that it took some time for the car to do it's relearn thing before seeing stage 1 gains? Right now the car only has any real pep at 100%, and even then it's not as good as stock. I am wondering if the Cobb stage 1 just isn't good at my location, the same as on my '08.

    I'm running 93 so I maybe better gains. ..I felt it immediately afterwards. ...at first it felt a little slower because it didn't surge at 2500-3000 like before. It's more deliberate yes you give it more throttle but that's what I like, not jumpy at light throttle now. I can definitely feel gained power in upper rpms whereas before it died after 4k.

    We'll fill up with 94 next time and try the 93 map. Thanks for the help!

    There is a beta map out now v108 with HWG maps also along with your others as before with some revisions. Throttle is better and the low load knocks got a lot better. I'm running the stage1 93 v108 HWG map and boost has also been better.

    Here are a few links to my last logs if you care to take a look. Done in fourth gear 2500rpm to redline.

    Do you guys think it's worth getting a Cobb AP for my 15 WRX if I have only done a Nameless axle back mod with 4" mufflers? BTW the Perrin shifter bushing and shifter stop are well worth the $.

    That depends - what are you looking for from the AP? The stock Cobb maps will give you a more linear power curve and a little more power itself. If you are looking towards the AP as a way to apply and remove protune maps then it could make more sense. Keep in mind that you are likely to cause warranty issues if you apply any map with the AP or any other tuner.

    Thanks for bringing up the warranty factor. The car is plenty fast for me right now but smoothing out the power curve would be a welcome improvement. I'll probably wait until the warranty period is over.

    Warranties are over rated.

    That depends... if the engine goes quickly on a new model like this then you're gonna be out a large number of sponduliks if it ain't covered. It's a game of odds really, because the chance of an stock engine blowing is pretty low.

    Exactly.. and the odds are against you. The company selling you said warranty (FHI in this case) is playing the odds and making money off of the consumer, otherwise they wouldn't offer a warranty in the first place. The main advantage for the consumer is piece of mind.. they could sell the cars cheaper, and offer no warranty, but then sales would be down in spite of the lower price because people would be worried about that unlikely chance that something might go wrong.

    You're thinking of the extended warranty - yes, problems with cars follow a U-shaped curve. Most major car problems happen in the first year or after the seventh year. That's why most extended warranties are offered for up to seven years.

    I was talking about blowing the included warranty with a tune. The 2015 allegedly logs driving events which exceed a certain threshold, but until we start seeing blown 2015 motors then we won't know how specific this is. If the logging is true and not just a paragraph in the owner's manual then I would wager there will be more warranty denials, not just with modified cars but also stock ones which have been driven hard. The chances of blowing an engine by applying an OTS map is extremely low but anyone doing so should realise it's not completely risk-free.
