Here is a little update from Cobb for those of you that don't read m a z d a 3 f o r u m s

We will likely be raising boost slightly on Stage 1 (no hard part modifications) and more with Stage 2 (TBE) but again.........we will run the boost we feel is appropriate. If you decide to remove a lot of good technology (the boost controls on the MS3 are very good compared to fish tank equipment AKA bleeder valves) than you do so against our recommendation and at your own risk.

We most likely will not take deposits. Keep in mind that most of the distributors will have AccessPORTs on the release day as well. But initial releases are always a lot of work and sometimes no matter how hard we try we may not be able to take care of everyone on the first batch.

At the initial release the tuning software may not be out for the Professional AccessTUNERs. That is anther long bit of work as well.

Fuel pumps on Direct Injection cars can raise fuel pressure at the injector. If they do under any condition(s) then a change in fuel mapping will be required.

We can tune out boost spikes. Fixing the fueling may work on stock ECU cars, but with ECU tuning things may be different.

What have you been able to do to the MS3 so far?

We have been tuning for everything from stock to TBE, Intake, and FMIC. The results thus far are very good.

Has your project car been flashed with the AP? I know there was an after
Sema buzz that someone from Cobb said the car has never been flashed with the AP.


Didn't know we had not said specifically that we have tuned the MS3 with the AccessPORT, but here it goes........

It has been flashed with the AccessPORT and we have been doing some tuning and testing in house for some time now.

We are still doing the same. Dialing-in the tuning, seeing what maps we need access to etc. We had been doing tuning before SEMA. When Tarzan (Eiji Yamada) drove our MS3 at GT Live (last spring) it was in the primary stages of tuning and his first comment was that the car was powerful. At that time we were using our in-house software and skipping the AccessPORT (as some of the changes were being made to AccessPORT base programming at the time) but that work has been completed and we have been using beta AcccessPORT tools in-house for some time.

Will it be able to turn off secondary o2's for catless dp's?

Yes

Can you raise idle?

Yes, but it has not been required thus far.

How is the boost control, is it similar to some of the high end BC with gear and/or rpm based boost control?

the boost control is MUCH better than any form of aftermarket boost control hands down. It has the ability to alter boost for gear, speed, RPM, throttle position, ambient barometric pressure, and other factors.

What AFR's are you tuning for especially in the high rpms were it dips into 9afr?

We are not targeting one specific AFR. To do so would be taking things back. We are leaning things up in most areas of full throttle, but not to a specific AFR. Different RPM, throttle positions, and different load values require different AFR's for power, reliability, and efficiency.

The SF Intake airbox is not ready yet. We are having to make a few changes to make it easier to produce. Pretty common when we get feedback from our laser cutting and bending contractor. Smile

Many of the hard parts for the AccessPORTs of all models are the same. And all of the engineering is done there. It is programming from here. We prefer not to release data until all testing is done. Just our way of making sure people get the most correct info possible. We prefer that the hype comes from how it will be released.

To change maps you only have to plug in the AccessPORT and switch maps. Takes a few seconds.

ETA for parts...

AP 4 ish weeks
FMIC hopefully 6-8 weeks
SS maybe a couple weeks after that, this one os pretty vague, but the latest prototype fit as planned, just improving feel of the mechanism now.
TBE hopefully about 4-6 weeks
Tuner software later this year, probably 4th quarter

This is our current plan. Things could still change. The AP is the most firm though.
 
They have had control over the throttle for a long time. Here are a couple quotes from Trey over on Cobb Forums.

For the electronic throttle, we do have control over it.

Yes, we're still on schedule for that. I'm capable of fully adjusting the fuel, ignition advance, intake cam advance, boost control system (very in-depth!), speed limiter, throttle mapping, and a whole bunch of other things I'm probably forgetting at the moment.
 
Can someone give me the lowdown (skinny) on accessport? I'm a Cobb newbie. So there will be base maps that authorized dealers can flash with, correct? And "prof. access tuner" allows customized maps? Thanks...
 
Are they still setting it up so that if you don't have Cobb parts, your SOL on being able to flash for an intake, exhaust, etc.?

When you buy the accesport it will come with the base map, you plug it in and it's done. If you upgrade in the future ie. TBE etc. then you can go to Cobbs website and download Stage 2 software. The "prof. access tuner" is where you get a customized tune at an authorized tuner shop.
 
ok, so i told myself that i would wait a bit to let other people guinea pig the AP for me, but now that i see that release is only 4 weeks away, i don't think i'm gonna be able to stop myself when it hits the market! (bang)
 
Makes me want to trade in the wifes car for an MS3 :(

...im excited to see this coming for you guys though. Badass unit...

With the throttle control will the engine make power all the way to redline?
 
so with the AP theres no need for a boost controller right? i was gonna buy one this week but not if the AP will take care of it

This was a question I asked as I have heard them say it was a pretty advanced bc within the stock ECU. With what they describe they can do there really is not a bc on the market to compare.
