It was before the Procede was released. No doubt, it works well too. Nice cars!

PnP status...?

Pnp harnesses are being test fitted to cars this weekend, however only for the speed6 at this time

i was told today to expect about $200 retail for the PnP harness on mazdaspeed6s. the harnesses and plugs are radically different on the mazdaspeed3.

i would bet on pricing being the same but i don't forsee a speed3 harness making it before the holidays.

Okay, Stephanie, open airbox or closed this time? And what what was the stock displacement and hp? The MS3 is already putting out 115 bhp/liter. Getting another 25 to 35 bhp/liter with just an ECU mod is going to be a lot more difficult than it would be on a less highly tuned engine.
I couldn't find any other MS3/6s with the XEDE that have dynoed except one MS6 on Mazda 6 Club (jcgemt2003). He put down 268whp/300tq on a Dynojet using the base tune shipped with the unit and a CPE CAI and a custom TBE.
So, for the sake of argument let's assume he would have dynoed 220hp when he was completely stock using a less generous Dynojet than the one you guy's used. That would be a very impressive increase of 50 hp . . . with a CAI and a TBE. FWIW it's another data point that's not a 50-70 hp increase with just an ECU mod.

BMW 335i, 3.0L Inline 6 Twin Turbo. When they first came out with the XEDE, they were putting down about 320 at the wheels with more torque. Last time I looked into it, after switching to the "PROcede", Vishnu was about to offer a package of just a PROcede box (XEDE with more plugs basically) that would put down around 380-400 (I know is a big spread, but it was still in the tuning stage) at the wheels in both HP and TQ.
Bone stock, 335is are dynoing around the 270-280 mark. Thats a 100 wheel horsepower increase. From nothing more than a little PnP Interceptor.
I swear, this forum...

What do you mean by the "this forum" comment? Personally, I have no axe to grind against XEDE/PROcede/whatever. I suspect that I am like many on this forum in that I would probably opt for whichever EMS beats the others to offering PnP at an affordable price. But you have to compare apples to apples, stock to stock, mod to mod, Dynojet to Dynojet, etc., when throwing out figures. If you're gonna talk about hp increases in engines with different displacements, you need to look at hp/liter to make a valid comparison.
So, back to the BMW with the 80 whp increase Stephanie mentions and how it compares to a 50-70 whp claim for the MS3. Sticking with the manufacturer's bhp rating, a stock 335i is rated at 300 bhp or 100hp/liter. It's got to be a lot easier to bring that engine up to 131 bhp/liter (claimed 80 whp / .85 powertrain loss / 3 liter displacement = 31.3 bhp increase) than it is to bring the MS3 up from 114 to 140-160 bhp/liter (using the same formula for the claimed 50 to 70 whp increase).

I admit I know next to nothing about turbo car tuning. However from what I've read these units are piggy backing off the ecu to tune the cars to yeild a better performance without worrying about a ecu flash being detected by the dealer. Why doesn't one company come out with a highly tunable ecu replacement that you can basically swap for performance. I know the costs would be high but overall no extra wiring and lots options and you could swap back for warranty work. Maybe I making a fool of my self but it was an idea. I realize that if you you tune your aftermarket ecu for your new high pressure fuel pumps and larger turbo's you can't ever use the stock ecu again but when you go that far you already know you've voided your warranty.

Thats simple, they have to add everything in there for other systems that ECU controls besides the engine. Can be very costly and problematic. Systems like that already exist but they will only control the engine, aka FAST system. Paint o tune but theres more power on tap. Generally considered racing only applications.
Piggy backs are the solution for now, that is, if the MS3/6 catches on and gain momentum with more of these engines installed in other MS vehicles in the future. Everyone seems to be on the fence as who will have the best tuning solution when PnP systems come out. For me, its who has the best PnP setup with the most parameters i can tap, with ease of use.
Yea I agree with you I would want the most accurate tuning possible with being able to dial it in with exact parameters while being easy use dont get me wrong I suppose I want it all but who doesnt when your the one buying it

Exactly. Our computer controls everything from the engine as well as the health of the CAN-BUS wiring of the entire car, and that communication includes the stability control, ABS, etc. The CAN-BUS runs it all, and then runs into the ECU. This is a LOT for an aftermarket to emulate, and they run the very high risk of messing something up that can kill you (could you imagine if the code for the stability control got goofed up?!) The manufacturers spend MILLIONS getting it right. A retune via the AP option (in the future) or a piggyback both seem like viable alternatives to control just the things we need to within the engine management system. No need to touch the other stuff.
Side note. The mere fact that any aftermarket solution is interfacing with the ECU, means that there is a potential "of messing something up that can kill you". It doesn't matter if it is a piggy-back, inline or replacement chip, a full regression test or ATP would need to be performed to ensure that the entire system has the same expected behaviour as before and the only way to do that is to know the complete functionality and equations inside the manufacturer's SW.
