This is not meant to belittle COBB at all but rather to illicit support for them to develop real-time tuning capabilities for the AccessPort and their Access Tuner Race software (ATR).

Its a great product with tons of features offered with just one very important aspect missing. Real-Time tuning.

So lets urge them to develop real-time tuning in the near future. This would complete the COBB package and offer a great alternative for everyone. Being able to real-time tune with a laptop running ATR and using the Accessport as an in car guage/add-on, while not tuning would make the COBB an awesome entry level tuning tool. Especially at the $500 range.

Let the support begin.

 

Agreed, but something tells me if that is an added benefit, it will no longer be in the $500 range.

 

Wow and I was using my Cobb today with a laptop doing some RTT today!

Damn Cobb they scammed me! *shakes fist*

 

haha, seems to be some misinformation in this thread

 

You sir must be a god...


Or our local COBB rep doesn't know his own product.

Thats the point of this thread. To clear things up.

Let be nice about shall we

 

What exactly did he do wrong. Was he not able to connect to ur ecu?

Why wouldn't the dashboard come up?

 

The point of this thread is to clear this issue up. I've been doing research on which set up to go with. I do not have COBB or any other tuner product yet. I have always liked COBB but reading through these threads makes it tough to make a decision if the information is incorrect. The system I had in the past was real-time capable and would like to stick with such a feature.

With that said, I don't believe you have a reason to mislead anyone on here. You obviously have an accessport and are able to real-time tune with it.

But why would Travis, the rep from COBB state that Real-time tuning does not exist for the Nissan ECU's?

Just trying to clear things up here.

Is it possible for you to make a video, of your car idling with the laptop hooked up so we can see real time changes being made to the car? Real-time, without a reflash. Change fuel or timing or something to the effect we can see the idle drop or raise.

I'm waiting for Travis to chime in also. Sorry to put you on the spot Travis. Not attacking you tho! I like what the Accessport has to offer.

 

^ that posts says "Today" but when was that screen shot taken? I was told by Z1 in no uncertain terms (and more nicely by Jiggy O ) that this feature does indeed exist (as of July 2009).

So either that screenshot is old or folks at Cobb are spreading misinformation (something I was accused of by Z1!).

 

Then I'm confused as to what real time tuning is. I have my car running with a laptop connected to it and making adjustments to certain tables like MAF calibration to adjust my short term fuel trims.


There is even a Control right on racetuner.


Ctrl L-initiate live tuning.



That's taken directlty from the manual.

 

Real time tuning, as we define it, is the ability to write to the ECU in real time. So if you want to change fueling, you simply change the values in the tuning software and those values write immediately to the ECU. That is what real time tuning is. This is NOT available on the Nissan platform with AccessTUNER Pro or Race.

I believe there is simply a confusion of nomeclature or semantics. You can indeed use a laptop to tune your Nissan with AccessTUNER by connecting your laptop to the ECU and making changes. However, when you make a change you have to reflash the entire map, the changes cannot be made on the fly. We have this capability with our Subaru platform, that is the only vehicle it currently can be done on with the AccessPORT or AccessTUNER.

I hope that this clears up any confusion on this point. If you ever have questions about the AccesPORT, AccessTUNER or any of our other products, please call us at 801-713-0035 or email us at tech@cobbtuning.com.

and this true real time tuning function is available with osiris rtt!

 

Here is the thread that screen shot was taken from.

https://my350z.com/forum/tuning/4647...challenge.html

It was posted today 3/18/2010. I also was under the impression that real-time tuning was added in 09 sometime. But as I read more and actually asked Travis directly on that thread, I got confused. There are too many different positions on it, it shouldn't be this difficult to get a straight answer about something this simple.

I'm siding with Travis for know until I see proof.

Real Time tuning means you have the ability to change any parameter of the map with the engine running and being able to see a difference without performing a reflash. This includes, fuel, ignition, cam timing etc.

Jiggy: If your just messing with MAF sigmals real time then that is not actuall real-time tuning. Real-Time dictates you have the control over all parameters of the engine whiles its running. All parameters. For example, in my 240 I could have the car running and turn down the fuel at that specific RPM until the engine died. Changes made in real time effect the engine as its running with out a reflash. The car would essentially be running off the laptop as you change fuel, ignition etc.

Does this clear it up. I know you've argued this on other threads. I hope this makes sense.

Real-Time tuning should not be confused with what the AccessPORT can do while the car is running. Change maps, diagnose, clear codes, raise/lower idle, display engine data.

I feel real-time is a great tool to have. It saves time, and gives immediate results. Are there others who feel this is a required feature in a tuning package?

Dash: this is not a comparo thread. I like the features COBB offers over the other guys, its just lacking this one thing.

Thanks Travis. Again, not attacking COBB in any way. Just clearing things up, and I think your right, its a semantics thing.

Any idea of when or if COBB will offer this feature for Nissan owners?
Can you also touch on the "live tuning" feature Jiggy keeps mentioning. What does it do, what's it for ect.

 

I'm not understanding what uprev does that Cobb doesn't.

I'm looking at osirus manual right now. Page 16 second 10,6

Eventually RTT will be done via ROM(reflash) RTT via cipher is only a temp solution.


It sounds like the same thing to me. When your done you hve to save the file and reflash it to the ECU. It doesn't take effect and save to the ECU immediately

 

Osiris RTT (albeit in a clunky fashion via Cipher) moves certain tables from flash memory into RAM so that you can make changes as the car is running (like fuel at a particular load site). I believe they are in the process of moving this function more properly out of the Cipher codebase and into Osiris (haven't actually updated in awhile so maybe they have already).

You don't have to reflash during RTT because you are changing RAM. Once you are done with all the RTT, you can reset the ECU code back to "normal" to have it read EEPROM (after reflashing the maps back into EEPROM). This is pretty trick coding! It means that while you're sitting on a DD dyno, you can advance timing and see torque changes instantly. It's the most practical, efficient way to dial in minimum best timing (for FI anyway, imo).

 

Well said, this clunky fashion is why I haven't gone with Osiris. From what else I've read it also sounds a bit too complicated for the average to intermediate tuner. I tuned my built SR and consider myself capable but not an expert.

 

niZam, download the Haltech software and try it out with the included base maps. Based on what you've said, after your try it out, you'll figure out some way to pay for the thing! THAT is RTT with a GUI that is slick like no other.

 

I probably would love the Haltech. Not sure I can justify that price for a street car though. It's over kill and not necessary IMO. The 240 was stand alone, some things in the car didn't work and I never could get them to. I don't want that to happen again. I'd like the stock ECM to stay as long as it can.

Whats with the Z1 vindication? They told you COBB was RTT?

 

My fault for before then, I was under the impression that the AP could tune in realtime. I have only tuned fuel with it so far, because it has only just started getting warm here very recently.

The manual is very confusing for the AP, as it sems to reference this feature often. Thanks for clearing this up.

Sorry for before Dash.

 

Understandable.

I'm still curious about the "live tune" feature you mentioned. Could you explain it some more. Still waiting to hear from Travis about this also.

 

The Haltech still works well with the stock ECU - allows copy through even or you can use it as a stand alone fuel, timing, and cam controller. It is probably overkill for a NA setup.

Adam and Kwame at Z1auto wouldn't stop preaching about how "some folks" should educate themselves and stop spreading misinformation. No biggie, just having a little fun!

... and no problem at all JiggyO
