I have asked this question in several threads, each time the thread is deleted due to abusive comments by the same someone...

What I want to know is; what are the limits of each of the different Cobb map making software packages?
What are the restrictions, and what parts of the tune cannot be changed unless you have paid for the full blown Cobb tuning software?

Your asking a legitimate question I don't see why anyone would flame you. Unfortunately I opted for the Racing Beat tune as opposed to going the Cobb route. I'm sure someone here will answer your question Good luck!

I do know that after you have a custom tune already on the pcm, if you marry a Cobb unit then it will not save that custom tune. It will revert back to the oem one.
I did not know that when I bought mine. All I wanted to do was to increase my ignition dwell times a little and I thought having a Cobb would allow that without messing with the tune I already have.
So I am having to wait until Steve Kan comes to town with his pro tuner to get thinks set up right. Gets expensive.

Yes, while the Hymee tune is a complete package of hardware and software.
But, no training wheels either...

actually if you do not buy MM calibrations or the pro tuner package (expensive) whats the point of getting one?
Its like-- just the cobb itself, cant be used to tune the car--its just a flasher?
Heck the EFI dude can do the same thing?
I guess you could buy the expensive software and then use it for much more? But doesnt that run like $1500 or something?
I may be selling mine--dont know yet --i will see what Steve has to say.

You can change anything on the Hymee unit that you can change on the AP...just the AP is more user friendly in the interface.....

What is it that you want to do specifically? That might help with the feedback you are getting

There are a few things that neither can do

Supposedly Racetuner adjust the same things that Protuner does...if you have a supported ROM

Rote8,

When I bought mine, I had the option of downloading Cobb AP Tuner RACE. There appear to be several hundred things, most all of which I have no clue as to what they do (Exactly what is Closed Loop Exit Throttle Hyst.)

I can tell you there are 5 different options for idle speed curve based on coolant temp as well as 7 parameters / maps each for leading and trailing ignition.

I know how to load the software, and look at all the pretty options, that is it. If you get one from MM, it comes with a custom tune. You can only get a new one from MM.

I had heard the dwell setting can only be changed in the more advanced Cobb software.

Some people can screw up anything. I would love to hear the details on this, in particular I'd like to know how it reverted back to the OE program without you loading it in the first place.

Its my understanding that when the Cobb marries to the car it installs its own base tune?That is what Jeff and the Cobb man said ( sorry cant remember the name). Now i suppose you can install it and use it for monitoring functions without modifying your tune, but if to try to tune with it that is what i was told that happens.
If you have the Pro tuner setup then I believe it is a free base and it doesnt install anything before hand.

In retrospec and like you indicated, in my case this was probably a blessing.
The more I think I know the more dangerous I become.

It saves the existing tune and installs the tune you have loaded into the unit. Once you un-marry (grammar police?) the AP, it removes the installed program and re-installs your original PCM program (regardless of whether it was a previously modified tune or not).

So maybe there was just a miscommunication on what occurred. Sounds like you wanted to take your Pettit tune, modify it, and then reload it back into the PCM? This is not possible (for most of us any way). The way you either stated it or the way I read it, sounded like you were saying it didn't save the original Pettit program and instead replaced it with a factory base tune.

This:

Depends on your access to Cobb.

Incorrect. Whatever is in the PCM when you install it is exactly what gets put back when you uninstall it.
Not that we haven't explained that already a dozen times over the last 3 years.

It installs whatever you want - AFTER it saves whatever is already in the PCM.

Sign up for the WEB seminar!

If you have a PROTuner license, you can actually "expose" the saved ROM. What you can do with it at that point depends on your skill set.

I know this will seem disingenuous, but I don't understand what stops people from just buying the new unit with the included calibration package (even if you intend to muck about with it on your own with the RACETuner software).

For the price of a typical exhaust system, you get a brand new unit with a completely customized tune, done in near real-time via Google Chat.

I completed 17 new calibrations in just 3 hours this morning, live and in real-time. I think the longest wait was about an hour.

But, whatever...

You can pull, save, and expose the existing tune with the Harrison APEX too, same situation with the skill set

the web seminars are highly recommended

Well, you can do it with a EPROM emulator and a HEX editor, too. (Which is essentially the same thing as Dan's setup at the moment.)

At least with PROTuner, it is still a calibration file that you can look at in the usual way.

Thanks!

Sorry if I caused any confusion. Jeff did say that it would save my oridgial tune. A cobb fellow by the name of David said that it it was likely that it would overwrite whats on there.
Since I dont know what the heck I am doing with this thing I opted out of trying. Instead I choose to wait for Steve Kan to come to town.
Jeff does a good job with remote tuning especially since he started his present system,but since i am so tech challaged I prefer a live session with someone elses fingers on the buttons.
My initial impression concerning the Cobb was that I could install it and simply change the dwell time (so I could run an upgraded ignition system). It ended up being more complicated than that? I should have researched more before I bought it.
Who knows, I am trying to learn, doing some reading etc. I think I understand some of the basis of tuning the rotary but at this point I am a klutz when trying to figure out what screen i need to be on, what field I need to change the values in and how that affects the entire package.
Again I apologize for any confusion i may have caused.
