The impression I'm getting is that a simple copy of the table values may not be enough to get the exact same performance across two different tuning platforms. Although no one was willing to answer my question about this directly (or my post was missed), it sounds like a flash does more than just alter the values in the tables, it also affects the logic the DME uses to determine what to do with these values. Would someone with more intimate knowledge of flashes please clarify?

i don't think the accessport modifies the DME logic..........yet


the openflash tablet may already be modifying the DME logic; i haven't played around with mine enough yet to answer that definitively. maybe shiv can clarify

Correct. The difference between the OpenFlash tune and the other flash device tune isn't what you see (values in the tables) but rather in what you don't see. You'd have to map a DME with both devices (mapped identically), read them both out and do a hex comparisons to see for yourself.

Update:

The rough shift from park to reverse went away. I think I was right. It was just some weird adaptation issue.

$395 is a steal right now!!! Get one before they are gone.

I would have this issue with my cobb ap but would go away eventually.

Excellent. I was hoping it would. I've been driving around a 6AT test car for the past few days and I didn't notice any shifting issues. And my memory was too poor to remember if there was any just after the flash.

That's very interesting. To me, that suggests that an OpenFlash OTS mapped car could potentially make more power than even a Protuned COBB car if the DME logic programming is superior.

Bingo!!! The back end programming that no body sees is the key to the smoothness and overall being more powerful than the Cobb OTS flash and possibly ProTuned.

I am in the market to buy a COBB or an OpenFlash Tablet..

I am not sure what to buy at this point now.

I am running stock car, but don't want to kill my turbos prematurely. It's wgs already rattling.

Buy my cobb ap so I can buy the open flash tablet.

Did anyone experience anything weird when loading any of the OTS maps?

During the write process, I could hear the fuel pump running the entire 10 minutes. I also got a stability control code and a TPMS code, as if something happened with the ABS.

And now when I unlock my doors in the morning, I no longer hear the fuel pump prime itself like I always have since BMW made that update to help with cold starts and long cranks.

[Robert@vishnu]

Fuel pump runs during the 10mins of the write process is normal. That is also why its crucial to have a healthy battery.

Why doesnt the fuel pump prime when first unlocking the doors after the DME has completely shut down? (like when your car sits over night)

We make no changes to the fuel pump routines so it should behave as it as behaved before. You can always confirm this by flashing your original map in. My experience with the factory FP prime feature is that it only does the prime when fuel rail pressure is below a certain value. And it's not always below that value. I bet you will notice it again. It never went away. You just probably caught it when it wasn't triggered.

So, the natural options would be Cobb vs OpenFlash both with the respective OTS maps.

Do you think it makes more sense to compare Protune maps with Off the shelf maps? Protune maps are extra $. Moreover, they are custom tuned to the car. Its totally different and unfair. For me, it makes more sense to compare free of charge, off the shelf maps against each other. Also, comparing different custom tunes at extra charge against each other makes sense to me.

I don't agree that having an access to same tables means that the numbers are the same. Now you have the access to the same tables, so your tune would have the same numbers as Shiv's or PTF's? I don't have any idea of your tuning capabilities, and you might not have either but considering the in practice infinite number of possible combinations you can enter the values in the tables, there is no chance that the values would be the same for all of you three tuners. There will be a difference in how the car is tuned by someone who has been tuning cars for his full professional life and with someone who decides last year, that he can tune cars in the evenings after work and get some additional income.

Basically, having the same boost, ignition advance and fueling results in the same performance. But the only way to have exactly the same boost, ignition and fueling across the whole rev range in all the ambient circumstances is impossible by any other means than copying all the figures from all of the tables from one tune to another. That is called copying though, not tuning.

U are missing my point. I am not debating whether you or anyone else should buy Cobb or open source. That decision is up to you. I did not compare maps either , i am doing exactly the opposite saying it does not make any sense to compare 2 maps and come out with a conclusion that one tune is better than the other. All i am saying is that the 2 are the same (other than price) so saying one is better based on Dyno numbers does not make any sense . A master tuner like urself should know that.
Now comparing shiv tuning abilities to the PTF guys is another story ( i do honestly think Shiv is the best tuner we have here).

I installed the tune in my 6AT today and havn't noticed any shifting issues. Its actually shifting quite well and just like stock (other than it seems a little faster).

The only time i had a rough shift from park to drive is when im on a hill exiting my driveway. Any other time i've never gotten it. Maybe that's the same thing the Wesley Crusher was having?? Or maybe something totally different lol.

[jlcf22]

Im in the process of getting a pro tune with Cobb my understanding is that ots maps from OFT make more power, say i got the OFT is there any room to squeeze more power out of it with a protune? is there gonna be e85 maps available? and im guessing the only meth kit that would work would be the aquamist hsf-4 or can we buy a inexpensive meth kit with failsafe? this OFT is very temping!

I just installed tune and reset my adaptations completely.. My car was shifting slightly rough into drive and reverse..

[JETmn]

People lose sight of all the capabilities of a full flash like this. There is much more to it that just ignition, fuel and boost. Shiv, does the OFT do anything with the Vanos values? This could make a huge difference in mid range power and amount of boost you could run. Everyone needs to stop trashing on this and support it. More competition = better products! It sounds like Cobb maps might finally be getting updated, why do you think that is? Thank OFT for that Cobb guys!

So what aren't we seeing? Are there settings I don't have access to?
