standback or piggy-back system 2010+ 2.5l

Yeah I believe that is where they were/are located.

bringing my thread back to life.
edit: does anyone know a diy of getting the gen 2 ecu out of the car???
i know its somewhere under the battery, but has anyone done it?

[aZuMi]

Took this right off M3R forums:

If it is close to a MS3 it is fairly easy. So need to remove the battery box so here we go.
Take cover off battery box
Remove negative terminal clamp
Remove positive clamp
Remove the front piece, you will need to pop off a few plastic pieces that use this piece as support
Remove the ECU cover
Take off the two harnesses onto the ECU, there is a trick to this, look at it, press the center portion and unlatch
Take the hold down piece off the battery, two screws, and take battery out
Remove the battery box, three screws hold it down, you will need to pull the front up a little and pull it out.
ECU is on the side of the battery box, there are a few screws hold it in place

This is off of memory, hope it is close.

I think more and more guys in US are starting to send their ECU to Dynotronics. Will you be sending yours to them too?

[Kiyomi]

i cant c what the actual ecu looks like cause i cant c any more threads on that site...

With Dynotronics?

With Dynotronics?

yeah, just checking if they might consider coming to t.o.

[Chuckie]

interesting, keep me posted.

Dynotronics is usually at vagkraft every summer in August (or they've had a booth there set up for the past 2 years)

Here's the most recent review from M3R forums.

Well first off, the tune wasn't exactly what I had expected to be. I guess you can say I expected wayyyyy too much from this, for example I expected different shift points, seeing the tachometer go into the redline and such, because a buddy of mine got his tahoe tuned and that's what they had done for him, although I was able to see my speedometer finally go above 118, I got to about 125 and didn't wanta push my luck going any further. Joe informed me that the tachometer was off and he did change the engine rpm's.

He believes originally it was at 5800 and he changed it to 6500, but the tachometer doesn't go pass 6200, which in all honesty I don't get because I feel the engine stall when the tachometer reads 6200. Plus SLABY had said he let his 2.0 go to 7200 rpms with an automatic (http://mazda3revolution.com/forums/2...iew-2-0-a.html) I figured since I had a better engine and the headers, my tune would have been even better than Slaby's. I don't know I'm just a little confused as to what was to be expected from this tune. Also on previous posts that I've seen posted by Joe, he had said 18-25 whp gain for 2.5. In all honesty I don't see/feel that gain

So lets start,

Price for 2.5L = $550
Worth it = I would still have to say Yes
Performance Mods: CS SRI, RB exhasut, MSDS headers
Details: I did datalogging and I'm using 93 octane

I did notice a bit difference with the tune, it took a couple of miles for it to break in and for the ECU to see the changes I guess. I feel that my 0-60 pulls a bit harder as it gets there quicker. The throttle response feels better, alot less lag. It feels more crisp when you step on it. I wish I had done a before and after dyno but I had to save that money for new tires, which I already ordered. Hankook Ventus V12 K110, same size as original tire.

I do come out of turns a bit quicker. Overall though, I don't know, from seeing Jackf's and Slaby's review I was just expecting to be in like a WOW/Shocked mode, but unfortunately I really wasn't. I know my review might not have been what people expected and it might be a bit disappointing to some, but it's just an honest review from what I felt with this tune. But remember every car is different so some might get a better result than I did.

Perhaps later on, I can go back and do some more datalogging and make some changes or something but as of now I wasn't so much shocked with the tune but more like "ok this is pretty cool". I see this tune more as a better driveability than a performance tune.

Joe's a great guy and really knows his stuff, he is a bit hard to get a hold of but as you can imagine, he is a busy guy. Would I recommend this tune? I would say go for it, but don't get your hopes all that high, thinking you can be in 2 fast 2 furious or something.

Like I said, this is just an honest review from what I've felt. If anyone has questions, post and I'll do my best to answer what I can.

In summary...don't expect high hp and high tq, but more on the overall driveability of the car. Biggest fail in this review is he didn't dyno before and after - no facts and all subject to interpretation.

Another interesting aspect in the thread is there's an app in iphone/itouch that can connect with the car and you can run diagnostics. May have been covered in other topics, but I still think it's pretty cool.

[Kiyomi]

yeah, the tune is good for driveablity. plus i understand you wont get much hp/tq compared to boosted applications. the saying goes 100 bucks for 1 hp. the other guy who did the tune got around 5-8 whp throughout the range, not 18-25. dynoed. cant find the thread rite now.

[zzz3]

he spent $550 on a tune and couldn't scrape together $120~ total for before/after dyno?

Hey Justin, I've got a piggyback that is brand new that you can use to tune your car. The same piggyback was used to tune a twin turbo Mazda6 V6 so it will be able to do the 3 no problem. Its tunes injection pulse width for fuel adjustment, and has a A/D/A converter for timing adjustment so you should be able to get the results you are looking for. I'm asking $400 for the unit brand new with software if you are interested.

I am interested. just curious as to which brand of system this is. aem? apexi? also sounds like a great price. but would i be able to tune it myself, or would it have to go on a dyno etc?

[CelestSpeed3]

You can tune it yourself via datalogging and adjustments. The same way you would tune if you had an AP.

Brand is PowerMod (http://www.powermod.com.au/index-1.html) They're founded by a few engineers that left Haltech. It's a very good unit, I sold my 6 for the Speed before I had a chance to install it, the unit cost me around $750.

hey, i would love to get this off of you. and ur positive it would work on my n/a 3? if yes, lemme know when u are available so i can pick it up.

[CelestSpeed3]

It works on any car, you just need to wire it up.

I'm home tomorrow till about 4:00pm.

[terapr0]

sorry to revive this, but did you end up going through with the powermod unit, and if so, how's it working out for you??
Still interested to hear about this

this thursday will be my fourth time going to APH to try and get this done. hopefully it works. fingers and toes crossed.

Good luck. Hope it works and you get HP gains and a bonus - better fuel economy.

also curious about this. keep us posted! if it works well, may do the same thing come march when the snow comes and goes
