AccessPORT Alpha test started
#51
Jeff I know I'll discuss this with you more tomorrow but from my perspective some of the elements I was interested in (and hopefully are adopted by beta testers) were ability to disable CAT checking CEL's...I was hoping to get rid of the TPMS as well but I understand the liability reasons for preventing that.
I'm curious as to if the AP has the ability to alter the opening of intake ports (earlier or later) or under certain conditions like WOT. Altering fan engagement temperatures, changing or eliminating redline (hey I like my options) or being able to control or disable any of the onboard security functions.
I certainly hope that COBB opens the PCM up as wide as they can and don't limit the device to specific sensors or items. I realize there might be increased production time but I'd like to see complete control over the computer.
Ok, I'm done rambling! I can't wait to see this in action.

You can change the fan turn on points, control the S-DAIS, recalibrate all of the fuel tables, turn off all CELs, etc.
For instance, I've turned off P0131, P0139, P0171, P0172, P0300, P0301, P0302, P0410, P0420, P0442, P0455, P0456, etc...
Very important:
These things can ONLY be done with the AccessTUNER Pro software. You can NOT do these things directly with the AP.
This means you will be dependent on a pro tuner that has this software until Cobb makes the AccessTUNER Race software available.
I do not know how much of this functionality will be included in the AccessTUNER Race versions.

Awesome! I certainly hope that the software versions are the same with the difference being the protuner is an unlimited license while the street tuner is an individual license version.

My understanding is currently the testing process only checks for CEL codes and makes sure that the ECU wasn't reset or any CEL's cleared within the last 3 drive cycles.
There's been talk that there are states that have the ability (or will in the future) to tell if emissions equipment has been turned off.
For the time being you should be ok.

Keep the info coming, Jeff!!!!
This is very good news!!!
I feel that the StreetTUNER software needs to be able to do all the things the ProTUNER can but for only one VIN number. What most people will want to do is have a professional tuner with the ProTUNER software tune their car and upload a flash. Then they will use their copy of the StreetTUNER software to tweek that tune as they continue to modify their car.
For example: Say I have a Greddy Kit that I get tuned by a professional. Then I purchase the Mazsport CAI for it and now I want to retune. I don't want to spend $500-$1000 to have a professional tune it again. I just want to add a little more fuel to match the changes in the AFRs.
Hopefully this will be possible with the StreetTUNER software.

Go Texas Longhorns!
Jeff, any surprises thus far with the AP functionality? have you found anything in the base pcm program that surprised you? Is there any ability to adjust anything related to power steering? what all can you adjust with the idle? RPM?
Do you feel with the AP its possible now to create a decent PnP flash for the greddy turbo that should work outta the box so to speak? Granted it would have to be tuned somewhat conservatively but alot of people would surely give up 10-15hp for a "safe" tune.

It should be pretty PnP since it doesn't use actual injector duty/PW to tune.
Instead, you set lambda targets and it figures the rest out on its own by computing nominal PW based on an internal Ve table measured against calculated load (based on MAF, TPS, BARO, IAT, ECT and throttle position) and, in closed loop, WBO2S feedback, which generates LTFT which is factored into the open-loop operation just like stock.
You are just taking the OE tune and extending its calculated load range (the OE tuning is limited to a CalcLOAD of about 1.01 - 300g/sec [39 lbs] of air is a calcLOAD of ~1.67) and assigning it a lambda value.
You can set the idle to whatever you want. I lowered my cold idle a couple of hundred RPM and raised the warm idle to 850. Smooth as butter.
I also set the lambda target at idle to .98 (about 14.4:1) and turned the OMP up from step 3 to step 4.
One of the biggest obstacles to PnP tuning will be the wide variety of different MAF mounting setups and injector setups.
The latter is just a scaling issue, but the former may be really sticky since EVERYTHING is calculated around the MAF.

Just about everyone is using a 3.5" MAF housing. Do you mean the air needs to be undisturbed like the OEM intake and RB Revi, or ...?

Not sure about the peripheral CAN stuff, yet. You may be able to tell the PCM to suppress those as well, but we haven't addressed that in the software that I have at the moment.
Flow characteristics really play havoc with the MAF, so everything counts in large amounts, to paraphrase Depeche Mode.

Thanks for the additional info, MM. You'll be doing this as the advanced guy that can provide in depth technical knowledge. I'm just the typical noob that'll simply be using Cobb's provided maps.
