Is anyone running a stage 1 with Cobb on a 2007 WRX? Just curious what you think of the maps provided by Cobb and the performance benefits. Any Issues, etc. Thanks ----
Waste of money IMO. Off the shelf maps are craptastic. I would suggest getting an openecu custome tune for your car for a FRACTION of the cost. I would suggest Bullwinkle, he's a member on the board.
Well, as one of the members of this forum recently found out, Cobb's maps are a crapshoot. If you are thinking about buying an AP, I would strongly suggest you research the benefits of openecu. There is a great free stage 1 map posted on the OSecu forums here (you'll have to register to see the thread). EDIT: And yes, if you are interested in a custom tune, feel free to PM me. Thanks Dream.
They're just not very good, period. And the AccessPort is expensive. My suggestion would be that you do some searching on this forum and on NASIOC, there are many threads that have great information on this subject.
I have an AccessPort and I like it quite a bit. I noticed a definate improvement over stock and I also noticed a huge difference between the stock setting and the stage 2 setting with my downpipe on. Is there really that much more power to be had with a custom tune?
That's like saying that a Chevy Cavelier is fast if it's the only car you ever been in (other than Mom's minivan). Don't focus only on power; a custom map will also drive much better and be much smoother provided the person doing the work is decent.
I am not sure about stage 1 map but stage 2 is not a best option. You need to understand not all cars are the same. I think you might be ok with stage 1 map but if you plan on doing stage 2 I would recommend protuning it for your mods. I would think if you use Cobb parts with Cobb map you would be more beneficial if you don't want to tune it. All cobb maps were done with cobb parts and when you mix things up that's when you get problems. You would always get the most out of your map if you protune it.
To simply answer your question: "Yes." Exactly. In addition to drivability, a custom tune nets you a larger "area under the curve" throughout the powerband, and a peace of mind that your car is tuned safely for your car and the gas you run.
To answer your questions; I have an 06' LGT, Comparing power with a cavalier and a minivan is just dumb(minivans are WAY better). I said that I can feel more power over the stock setup, nowhere did I say my car was Fast, I do only have Cobb parts thus far, and I was just answering his question about what I personally think of the maps they supply.
In this case it is great IMO, you can have someone like Ronnie (locally) tune it or drive/wait for Jorge to come and tune it. Also you have different maps at the push of a button, no need to tote your laptop everywhere. Case in point "Blake" drove up to the ice races and was on E85, the closest E85 station is not all that close so he had the option of running that tank dry and switching to his 92 octane map. Yes I do agree with Tom and Nate, but then there are those situations where an AP on a car makes more usable power then anyone expects. Just look at Evan's car that thing is an absolute monster and is running an AP2 stage 2 map.
Everyone is going to have their own opinions but the guy asked for opinions from people that have them and are running them. he didn't ask if it would be better to get a tune. He wanted to know if there were any known issues and how people liked them. I have had no issues with mine, and I do like it for convenience was well as noticable gains.
OTS maps suck AP will allow you to switch on the fly... this is a + AP is expensive as a prostitute toting a kilo of crack... this is a - Open ECU is custom for YOUR car, 9/10 WAY better... this is a + Open ECU forces you to get off your butt, meet other members and get it tuned... this is up to you
Most of us have HAD them in the past and are trying to save him from wasting money on something you dont need, smart guy. But if you want to spend $600 on a crap tune, be my guest.
Like everybody has stated.. Go a different route....Bullwinkle Tune!! I have a accessport and got my stage 2 maps tuned by pdx. They made the maps according to what I have on my car. But that doesn't mean that they are running and giving me the best of what i could have. Had I known more about my options when I did mine a few years ago I would have gone a different route or just waited all together to change my cars stage status. I will be getting a Bullwinkle tune come spring because I feel this is in my cars best interest and well being!! There are alot of knowledgeable people on here and Bullwinkle is one of them. I would take his advice on what you should do. Also check out the maint/mod forum. There is alot of useful information on there.
This might have been stated earlier, but people who still have warranty on their cars are somewhat concerned about having openecu tune their cars. My understanding is, if maintaining warranty is an issue, probably better not to do a tune at all. From my readings, dealers/subaru techs can tell if a car's ecu was tweaked with - regardless of open ecu or cobb off-the-shelf tune. Someone please correct me if I am wrong.
If you have the tools (laptop, cable, and your stock mapping), you can flash directly back to stock at any time. However, if you (or the OP, or anyone else) is worried about their warranty, they should not be modding their car.
My friend used the Accesport to remap his ECU before trade in. He drove 100 miles on the stock maps and the dealership never knew it was modded because they checked it before trade in.
Depends on the dealership may be? I bet the smart people at Morrie's will figure it out. If what you say is true, it's good for me. :biggrin: stage 2 on a 08 rex will be nice... From what I read, the checksum of the ecu map (after reverting to stock) will be different from the stock map's checksum. I must say this is counter-intuitive to me as I don't see why the byte code will be any different if it's just copied back over - unless SOA has some security mechanism in place . Whether the dealership knows what the stock map's checksum was, is the question. Apparently, SOA used ecu maps with different checksum on the stock car depending on VIN sequence which makes it harder for techs to figure things out. I will stop here as most people on this board knows more than I do .. May be subaru tech's/pros will explain this for us.. I took unabomber's (nasioc mod) explanation for granted.
Jack, both sjwelna and myself have laptops and Tactrix cables if you want to see how OpenECU works and take a look at the setups. Just PM me on here if you want to take a look at it sometime.
OpenECU is free and very comprehensive; I see no better option for a daily-driven car. I definitely recommend a custom dyno tune for everyone, even if your car is bone stock, its a great modification.
I have a 07' wrx I had a Accesport, I sold it and am spending the money on exhaust,turbo,intercooler, and Tune. I would recomend If I was going to do it over and spend my first $700 - $1000. I would buy a sweet turbo back exhaust and a tune from Ronnie at R S Motors ( Open Ecu) The only way to get the best setup for your car with the differnt bolt on parts is to dyno it/ reflash the ecu.
I can hear the Angels singing in a choir... HALLELUJAH HALLELUJAH.... hallelujah hallelujah hallellujah!!!
