New Update on Cobb

Cobbforums has a post showing some new stuff they have developed for the MS3.

Here is a taste...

3: Intake... We have begun production of our S.F. intake. It includes the composite MAF housing with the same style of air straightening fins that our Subaru WRX/STi intakes have always had. The kit also includes a silicone elbow with vacuum hose nipple, hose clamps, and high flow cotton element filter. We are working on a box to turn it into a cold air intake, but those are not in production yet.

So no news about the accessport?

Last update was from Trey on May 21st.

StreetTUNER will be released, but after the AccessPORT has been made available. They won't be released at the same time. We're re-working the tuning software from largely the ground-up, so it'll take a little time.

Most of the tuning tables in the Mazdaspeed3 ECU have a good degree of resolution, as compared to most OEM ECUs. Fuel is a 3D table looked up according to RPM and Engine LOAD. Load is calculated by the ECU using primarily the MAF sensor (g/sec air flow). In most cases, for both fuel and ignition, you have control to over 400 individual data points (each).

Boost control is also very good. The primary control is based on RPM vs TPS and also has a very high resolution. It then has correction factors based on baro pressure (altitude), primary intake air temp, air temp delta (pre and post turbo), gear, etc. More precise than any aftermarket boost controller I've seen available on the market.

We also have identified and control over the Variable Camshaft timing, Throttle, and other limits like speed, rev, boost, etc. I've also dug out the injector scaler and things like injector latency, throttle pump, etc though considering how there are no aftermarket DI options available, I realized that's more of a future use capability.

The ECU also has quite possibly the highest resolution MAF calibration table I've ever seen. It seems quite important for Mazda to keep very precise control over measuring the air flow into the engine. Might be something to keep in mind when using aftermarket intakes or interceptors/piggybacks designed to tweak this signal. The ECU uses quite a lot of logic to validate the sensor values vs actual running conditions.

Personally, I'm very much in a highly focused mode right now working to get these, and MANY other, products to market this summer. We have a great group of engineers and support staff that will be monitoring the forums regularly, and answering questions. If you don't see me post as often, it's because I'm working with the other talented individuals here to get you a product available sooner rather than later. Don't take it as anything negative, I just find the forums somewhat distracting and I'd rather stay on focus for you.

Cheers,
Trey @ COBB
