Cobb AP impressions and dynos
 
I've read several of the Cobb Discussion thread, but I didn't see what I was looking for. And I did not read the entire thread since there's about 60 pages.

I was hoping to find people's opinions of the differences felt and other dyno results vs. what's on Cobb's site.

kennyfrc1 04-04-2008 08:16 PM

Everyone is busy playing with their fuel trims. :lol: I am not even considering it until I see before and after dynos.

Razz1 04-04-2008 08:45 PM

Please read the whole thread.

Moderators need to close this.

We don't need another AP thread.

kennyfrc1 04-04-2008 08:51 PM

Mods, please rename this thread Cobb AP Dyno results.

You can do that. Just edit the post.

actually, delete this thread until at least one person has a dyno to show :P

Good idea on having a Dyno results thread. Feel free to kill this thread.

But it would be good to read some anecdotal opinions on what people think thus far. I checked the Cobb forums and there's really nothing there either. Going through 60 pages on the Discussion thread is too much, especially when the pages I looked at were mostly about fuel trims and other technical data.

I'll contribue to this on April 26th. I have a dyno day set up, 20 cars are scheduled, more then half with AP's.

heyarnold69 04-04-2008 09:53 PM

how many of those are NA?

Phil's 8 04-04-2008 09:53 PM

I think Arizona will have a contribution in the next couple of days also.

at least 4 or 5

Skylee has put his car with the AP on the dyno but no graph. I believe he was running the base map from MM and has not moved on to the more agrgessive maps

Max HP: 185
Max TQ: 139

Razz1 04-04-2008 10:11 PM

Hell I got more than that stock!

Jedi54 04-04-2008 10:13 PM

he might have been on a mustang dyno???
Razz: you did higher on a dynojet

kennyfrc1 04-05-2008 10:03 AM

I am at 198/140 already. A this point the RB flash is looking like a better deal. I thas also been proven to work.

heh. How is your statement logical?

It's just fuel and timing. Can the AP adjust fuel and timing? Of course. So of course the AP can do anything the RB does. In fact, you can get a custom map made for your car, instead of a generic map that your car has to adjust fuel trims for.


Furthermore, without a baseline dyno, saying someone has 180 whp means no gains is illogical. Some cars make 170, others make 190 without fuel management modifications.

Jedi54 04-05-2008 11:25 AM

^^^ yup. No baseline = stupid conclusion.
I'll have some more definitive info after MM, CRH, and I dyno 20 cars in 3 weeks. stay tuned.

My reasoning:

Cobb states that on a close to stock RX8 you can expect close to 10whp. The AP is a great product, and offers tailored tunes for your car. It is perfect for FI, but much less of a value for NA. Team RX8 dynoed the RB flash and got 9whp. The RB flash costs $300 while preserving the cat converter and I dont have to constantly tinker with it(fuel trims). Will anyone get 20hp from tuning with an NA RX8, very doubtful. Only then would a $700 tuning product be worth the effort, risk, and aggrivation for an NA RX8.

Bottom Line for NA cars:

RB Flash: 9whp $300
Cobb: 10whp $700

Here is my Dyno prior to getting the RB flash which I will be ordering soon unless someone can post some Cobb AP dynos that can change my mind.

No it is cool no one is forcing you to get the AP if you don't see the positive effects it allows to give your car then you should not get it. When you ever want to adjust any thing on your RB flash have fun trying to do it. Get the RB flash and have fun not driving you car for a few days but when you get it I am sure you will be some what pleased.

There is no need to mess with fuel trims on the AP either. The car will settle after a while. What we're doing is allowing the map to build in the trims so the car has no adjustments to make.

RB Flash: 9whp $300
Cobb: 10whp $700
You mess out on the fact that the AP allows you to store and switch maps. If your dealer reflashes, you don't have to pay additional fees. You also get the ability for tweaking other params such as OMP flow rates. Or the AP itself as a odb2 reader.

You are correct however, that fuel is fuel. So if the RB flash pushes your car to the limits for NA, the AP would not give you increased gains over that. In a month or two we'll have the street port software out, and then the AP will also become a data logger, and you can modify the firmware maps yourself :)

Is there a missing the point smile?

Dont forget that the AP does more then just flash your ECU. Unlike the RB reflash, you can customize the tune with the AP, the OMP gets increased, the colling fans turn on earlier (how much is the mazsport cooling fan mod and how long does it take to install?) you can check and clear the CEL (how much does a mechanic charge?) You also get a race tune and a stock tune with 1 product, so if you ever remove your cat you do not have to pay another $300 for a reflash. There are a lot more benefits with the AP then I listed and I am very happy I got mine. Just like hitmann, I am not going to force you to get the AP, but if you think about it, it is a very good value and if you ever decide to go back to stock, you just reflash your car and you can sell your used AP and get a large percentage of money back. Try doing that with the RB reflash.

We dyno'ed three cars yesterday. Flashwing's, mine and MM's. I don't have any of the charts. MM will have to post those. But from what I saw with the Cobb AP is an infinite ability to tune your car. MM said he has over 500 maps already. And I can picture having 10 to 20 per car or more.
The main thing is every car is different. Be it the car, the mods, the weather the altitude. What Cobb has done is provided a way to tune your car perfectly for your conditions. You can adjust AFR's every 100 RPM's if you want. Same with engine timing. Watching that on the dyno graphs yesterday made me a believer in what a fantastic unit the AP really is.

someone must post those charts!
