Cobb AccessPORT Discussion
Pretty cool I just got my new accessport via MM looks like they changed the obdII port from usb to some sort of parallel connection my previous AP (long story) had the old usb setup this seems alot more sturdy nice upgrade.

^ What he said.... thats what mine looks like. Jeff what is the real difference between a usdm cali vs a usdm federal? Just curious.... Can a USDM CALI map run on a car identifying itself as a federal model and vice versa?

Curious to know what the 5th channel is on that connector... seems like they may have changed the way the AP interacts with the CAN BUS?
edit: for non-techies USB is 4 pins: 12V (power), Rx (receive), Tx (send) and Ground. The new connector has 5 pins... could just be a dead pin though.

There are 6 active pins on the RX-8 DLC: two for CAN, two grounds, power and the SAS/TCS/DSC/ABS system output.
The AP needs to see 5 of those 6.
The new connector is "dumb" - it doesn't interpret USB.

Ahh so basically the dongle's function are now right in the AP.
Probably a more efficient design and likely the reason they could reduce their cost: now they only need to manufacture one complex device.

I appologise if this question has already been answered (I searched the forum but couldn't find an answer).
MazdaManiac, are there any plans for AccessPORT for RX8 Series II model? If so, can you please give us any aproximate ETA?
I hope I don't sound too pushy. You have my respect.

I believe I've read about the AP being able to display information such as horsepower and torque (but after 300+ pages, I cant remember where I read it 
). If so, how accurate is that information? I know it can’t possibly be close to an actual dyno, but wondering how much difference there is. Has anybody compared what the AP shows and what there real dyno showed?
And is the AP consistently inaccurate to where, say, it’s always about 15% higher, within 10% of actual rwhp, always reads lower, etc.?
I was just thinking if it was possible use the AP to see how much of a “gain” in hp you get from a particular modification and how accurate that would be?
Example: The AP reads 170hp stock, then after some upgrades and a tune it reads 185hp. If the AP is consistently inaccurate, (or it IS accurate), you could still determine the amount gained (15hp).
If the AP does NOT have this function, then I have no clue how or where I read that and apologize

No but seriously Ive herd that up to a certin amount of horsepower u would have to get another source such as a intercept-x unit. I tryin to to get at least 450hp and like to know would this be a suitable app for what Im building
Engine prep? Who is building your manifold and downpipe?
What are you doing for injectors and ignition?
How big is your cold-side plumbing and intercooler?

objectve to build have 450+ engine
turblown is doing the build
injectors size ? Going run with a msd igntion setup
plumbing more than likey may be 3.5 or 3" and no specs for intercooler
I know is not much to go by but it's in the engine rebuildig process at this time.

If i know Elliot, the DP will be 3 1/2 ". You could do 4" but you run out of room very fast.
Can I ask you a question? Did you read the purchase agreement when you authorized payment? I'm sorry to sound so dickish, but it seems like nobody reads the sales agreement and then I get "has it shipped yet?" requests after two or three days.
