Oh guys don't forget the only time Al (Dynoflash) ran a 11.6 with a stock ECU was the one that Works flashed for him. His 11.5 with with a poorly tuned standalone.

I have a question.
Does the EVO use OBD2? Just curious if anyone does their own tuning.
It's cool that Dynoflash is out there, but from the domestic car drivers, custom tuning your own ECM seems to be more common.
I live in Colorado (read: mile high). A friend of mine said when he got his 2002 SS Camaro on the dyno, and ran it back-to-back with a hypertech tune, he LOST hp and torque across the powerband.
Dynoflash rep: Do you use special ECM programming for high altitudes? I'm not sure how much it might matter in a boosted car up this high, but on a n/a Camaro a generic tune sure made things worse.
(I am not comparing Dynoflash to Hypertech here, it's pretty obvious this guy knows what he is doing, and not just giving out generic tunes like hypertech) I am really just curious if Dynoflash takes altitude into consideration when he re-programs the ECM.

However, our version of the turbo back exhaust does not use a muffler of any type and is designed to work with the stock cat in place (of course, our track-oriented customers may choose to run a test pipe instead).

I can't speak for Dynoflash (but then, Dynoflash can't speak for Dynoflash here anymore,) but as far as WORKS is concerned, we do a lot of our testing at altitude and under a variety of atmospheric and environmental conditions (above and below sea level in a wide range of temperatures) in creating the WORKS Brain Flash.

Thanks for the response!
So have you had to make major adjustments because of altitude? I know the EVO uses a MAF system, which does help make for an easier tune at any altitude.
Bah, I still have too many questions. I think I will post my own thread here.

Dynoflash is by far the best bargain. I like the boost tube that Works offers with their reflash but it would be tough to justify paying the high price. Reflashing and tuning is not rocket science, it is really pretty simple if you understand the parameters of tuning.
I'd like to see a reflash offered that is similar to Works P2 but closer to the price of Al's dynoflash.

You actually raise a good example to illustrate my point above. One of the questions that a consumer should ask is that if boost mapping is offered, how is it achieved? I have seen vendor posts to this board describing a 10-minute delay being the workaround for holding boost. At WORKS, we actually took the time to engineer a hard part – the boost tube that comes with every P2 -- to allow the ECU to hit and hold boost as it was intended. Compare our boost charts to others, and you’ll see what a difference this approach makes.

Does it cost us more in both R&D and parts to do it this way? Of course it does. But then, we have our long-term reputations at stake and years from now and time will tell whether the cheaper alternative was in fact just as good or just as safe as the right way of doing it.
Also, consider that the cost of the reflash might reflect the amount of time and expense (both man-hours and dyno time) that went into it. Factored into this is the relative experience and expertise of those involved in creating the maps. If a company were to contract out the ECU mapping to an outside party, conceivably they could have the maps created for a fraction of the cost compared to a company paying its own engineers a salary to do nothing but create maps for the Evo.

This makes the production of generic "improved" maps fairly simple (although time consuming). Now, these maps cannot be very aggressive as there is an ever present danger that a particular engine might not function very well or very safely with an off-the-shelf map, right?
Anyway, although this is not as simple or easy as it sounds, the reflashing of an ECU is basically the remapping of timing and A/F ratios at various points of engine load and speed. These are changed to optimize power output while retaining safety of operation, right? Now, safety of operation is determined by logging the function of the engine and making sure that the values entered in the maps result in more power without knock or excessive exhaust temps, etc.
I don't see how any particular tuner can deviate from these principles to produce effective and safe ECU reflashes. How can there be any significant diffences in reflashes as long as they all produce the same result? Obviously, the best reflash would be the one that's custom made for each car.

Good luck to you. You can count on my business and my support of your products and services. Everybody else in Atlanta who met you and got the dynoflash i'm sure feels the same way
You have no need to defend yourself, everybody can see clearly what's is going on. Please don't take the bait

Most US Domestic market cars after 1995 have some form of OBD compliant diagnostic port.. All computer controlled cars (for US market) after 97 were required to be OBD-II complaint.. So the answer to the evo is yes.. its OBD-II.
Tuning the ECM (Mitsu calls it a PCM, Powertrain Control Module) is a little more complex.. For one reason or another, things like the Power Programmer (That are available to allow the end-user to flash their own ecu) don't seem to be available, or nobody has made one that will work. It seems the tuner market prefers to use Piggybacks (though some of the hypertech products are indeed piggyback products) entire replacement ECU's, or Tuner Flashes (not end-user applied)
I do know that the inline code in the Evo is fairly complex, and rewritten as part of the flashing process and therefore if you foul up flashing the computer, it renders the entire computer basically useless, where the Chevy's tuning parameters are stored seperately from the ECU's Firmware (both are flashable however)
In addition, the data is typically encrypted and not easily extracted (downloaded off) from the ECU as it can be from many american cars (So you can revert back to its previous settings)
Therefore most flashes need to be done by a professional with the right tools, and parameter changes are a little more complex than adjusting shift points, converter lockup, speedo correction, etc.. that you can find and adjust on a GM car.
Ultimately the answer is nobody has developed hardware intended for the end-user to do what a power programmer can do.. the closest thing we have to some of the hypertech products (or jet-chip products) that plug Inline to the ECU, are the piggyback tunable fuel computers.
I would love nothing more than to have the hardware to tune my own ECM.. But after researching the expense, its just not cost effective to do it as an individual (Lets just say the software alone can cost as much as $3000, and the hardware ranges in the $2000 range) Plus you can REALLY foul up your car with this stuff if you aren't really familiar with engines, and tuning (more specifically how tuning is done on these kinds of cars)

It's abundantly clear they have found your buttons and they love to push them. Actually they love to stomp on them.
Silver - as to your other post about what goes into reflashing, I also agree.
Everyone offering a reflash, regardless of their specific methods, are playing in the same ballpark, and have to
do similar things to achieve similar results.
There is no "magic" involved.
I believe this is what aggravates most Dynoflash detractors.
Several venders offered a service for what seemed like a reasonable price.
In walked a guy who offered a similar service for less.
"He's a hack" they cry. "He's not a real tuner" they wail.
But at the end of the day, as the old saying goes, you turn them over and they all look the same...
Gee Al, maybe you should have been charging a grand for your service.
Maybe you would have gotten more respect as a real tuner...

Without starting a whole debate, its pretty obvious that the "Tuner Market" is based on price, or JDM.. The perception in the Tuner market is that if its Japanese its got to be better, or if its really expensive, it has to make more power. To some extent, there's some truth in it.. But its within reason.. there are three types of products you can buy..
Functional
PRetty
Functional and Pretty
Which do you think will be most expensive? Most of the tuner market is as much about bragging rite (How much you spend, how much of it is JDM, how complex, how loud, etc..)
The performance market is not quite as bent on how much you spend, and how pretty it looks (though it doesnt hurt to have nice looking products) since many of us could not care less about impressing someone at a car show and many of us prefer to keep a low profile on the street.
