ok, maybe i missed this question/answer that i am going to put out there or maybe i just don't know enough, BUT can I put this ems in and safely run it without having to replace the exhaust. Or I should ask, do I have to replace my exhaust pieces with this ems due to the remapping and increases, or is it just that I would see full potential if i changed that stuff out? I'm rambling a bit so that may have been unclear.

This has been quite for a while.
Being in California, while I want a downpipe, I live in fear of the smog checkers bouncing my car for either mods or not passing the tight sniffer tests we have every two years.
I would need to know a downpipe would meet CARB testing to go ahead with getting one. They are not like CAI which I can swap back for testing...

I am also interested in an EMS but I have the same concerns.
You don't need any other mods to run an EMS. The EMS will allow you to get more power by adjusting the overly safe factory tune. It will also help you get the most out of any other power mods you might have as well.
In theory, you should be able to have the EMS in place during a smog test as long as it's tuned with emissions in mind.
And who said you couldn't swap a downpipe back to stock for e-testing.
Should only take about 30mins.

Typically you have different tunes for different mods. I am speaking from my experience with the Subaru world.
"Stage 1" - would be tune on completely stock vehicle.
"Stage 2" - would be for a vehicle with turbo back exhaust
"Stage 3" - would be with a bigger turbo, injectors, fuel pump.
There would be a different map for each one....with specific mods listed.
It all depends on how flexible the ECU at compensating on fuel delivery
What we need!!!
ON our CX7 the much needed EMs would have to do at least
1. Get rid of the limiter
2. Get rid of the torque drop on higher rpm - so we dont have to shortshift the b****
3. Add some boost pressure for the racing savvy (drive2)
only then we can think of the other modifications possible... (eekdance)

Well I should be getting a CX-7 very soon and I definitely would be interested in getting the ems! I installed an AFC on my MSP and it made a huge difference and I havent even tuned it yet! Of course my CX-7 will not be as modded but I would still like to find a little more power and better gas mileage. I also think the PnP would be the better option since if we have troubles with our cx-7 we can just unplug it and take it in for service.

I'm in for PnP EMS... on a lease so I can't be cutting any wires!
Got an update from CP-E today:
"Good to go. We have already put one on the car and he has been driving it for 3 to 4 weeks now. THE PNP will come out for this car only if the pnp for the speed3 matches the cx-7. We still do not have the pnp for the speed3 yet. The mazdaspeed6 connection will not work, it is not the same connector.
Very Respectfully,

Hey guys, I just wanted to chime in to let you know that we have another thread about the CX7 Standback here:
http://www.mazdas247.com/forum/showthread.php?t=123671305
That thread contains a lot of information not only about our Standback engine controller, but through datalogging we learned a lot about the CX7 and what its capable of. The first painful lesson we learned was that this thing needs a new turbo! Our log of the boost pressure is here, and notice how the pressure tapers off as boost climbs:
Our Standback engine controller has a very unique PID feedback loop attached to the boost control, so if the turbo is capable of producing the boost you're commanding, then that's the pressure you'll get. In other words you type a boost pressure into the Standback software (eg. 17psi) and that's the pressure that our controller will target automatically. So, since the CX7's boost began to taper off despite the feedback loop, we've come to the conclusion that the turbo is quite limited in the CX7. We also plan to dyno tune the CX7 to see what kind of numbers we can get our of it, and I'll update you guys as soon as we have some dyno graphs to share.
I'll be happy to answer any questions you guys may have concerning the Standback engine controller, so please feel free to post them up here.

Looks like something is out, but it does not look like the plug and play version we have been waiting for.
