My motor also blew today.

[ms3077]

I'm thinking as long as we don't exceed 19psi this motor will hold up fairly well, at least I hope. I will be happy if I can run my Cobb SRI, Race Pipe, forged BPV and an AP tune @18-19psi without much worry of blowing my motor. This should but me roughly at 280-290whp I think and I would be content for a while.

+1. I'm running cobb sri, tip, su tp, and ap 18-19psi and I think I'm done with the engine mods. Car doesn't need anymore power with less reliability. Time to start on the suspension.

[lidokrantz]

I feel for ya brother....another blown engine sucks big time...and i wish ya well with getting her fixed.....
And for the record i dig this car toooo much stock with a CAI to bail....i am in it for the loooong run to 100,000 miles at least..Still like the car....no matter what good things Laloosh has to say about it...

how many times does one have to be reminded that this car is a tempermental fuck in cold weather and you must drive accordingly....as in the summer when the car is heatsoaked, it's best to drive her easy till the temp gets back to a normal range for going WOT or fast....indeed a combination of mods, and the weather changes the tune so be aware and compensate... I am convinced that driving this car CORRECTLY....which means sometimes medium throttle and easy when needed.. and not beating the piss out of it ALL the time will yield many fun miles on this car stock or slightly moded, and for some who tunes for there mods many more miles....Building the car first before trying to make extra power is safer, but expensive.....or be a slow, fucking driver like me, and hit it once in a bit when the conditions are right for going fast ,or stay stock and not worry about it like me.....in NJ it's hard sometimes to go any faster than 40--50 mph going to work so....stock for me is plenty fast and if she blows she blows.....but i am still driving correctly in all weather conditions regardless of the warranty..i do not buy into the go WOT or don't go at all way of driving...never have never will....and i never blew an engine in 30 years of driving....

well in 30 years you never had a Mazda DISI engine either, just remember stock motors have blown.......
never say never with this motor! I used to think like you , I hardly ever beat on my car then boom changed my way of thinking......

What should be the range for boost in colder weather?

[Driverman5777]

This is why I love my standback... some things are better left alone... and being able to run a very conservative map, and then change to a hotter one is amazing

+1 this is why i just bought a sb instead of ap - the majority of people i've seen blow on this forum (at least since i've been around) are ap users
i agree that the ap is the most powerful tool that is available for tuning the ms3, but just like cobb said to everyone when it came out, atr is for experts - there's no safety net, period - at least as you push the barriers of what you can do by tricking the sensors with sb you still have some of the safety net the ecu provides
- i'm sure we'll see even more blow ups in the next few months as we go into winter and i'd be willing to bet a couple things -
1. they will be using the ap
2. it will be something that happens in cylinder #3 (I was surprised to see the guy the other day w/ cylinder #1 - but if it's not 3 it will be 1 - the leanest and the richest ones from our pos manifold!)

[turd burglar]

Mazda needs to lick butthole for makin such a turd. TIME TO PAY THE FIDDLER WHORE!!! Sucks to hear man

[easy]

i think having less turbo lag is more benefical than adding more turbo lag. More lag makes you want to step on the throttle more since it feels like its not moving and creating more load.

also i not to sure about the DP and FMIC idea causing the blow ups, i blew up with just intake and BPV, and what about the stock cars that blew.

also the mention of all of our tq coming at 3k being to low in the rpm range is something i don't think is the issue, the GTI max tq comes in at 1800 rpm, yea in stock form it has lesser tq but i don't think the bolted on GTI have these issue.

[cpolly69]

I think everybody should get away from using the stupid pid loop to control their boost in the first place - I don't care how fine tuned that table is, it sucks in comparison to a mbc or a high end ebc

If only we all could understand this.

[Driverman5777]

with the standback there are only a few parameters to change. You aren't going in and fucking with variables that many of us don't really even have an idea what their purpose is.

[flyrevs2]

anybody know if many peeps with the Standback have blown ? Wow this would really suck if it turns out the AP is causing blowups.

[johnnyspeed6]

everytime this happens everyone makes excuses for the motor popping .. they are just not well engineered ... bottom line AND bottom end .. im counting the days to get back into a mustang if mine makes it that long ... got an email today from the guy that bought my stand and drove it to cali with 110k on it .. said its running strong and feels great ..... fuck ..... this .... car ... never again will I step foot into a turbo DISI engine ... fuck mazda and everything it stands for .. mustang #3 here I come .. (bullitt)

[AeroDesigns]

its all about tuning gti = 200 hp Seat leon same engine better computer = 240 good example...

Hey..its not mazdas fault people are modding out of the engines own limits. The car stock, is great and thats what they sell it as. By modding the car like any other, you take the risk of messing up the engine. You gotta figure..how else did mazda make this car so cheap for the bang you get.

Don't get mad @ mazda for selling a stock car with great performance and affordable price. And the same goes too all the others bitching. You want great power performance...shell out the cash or GTFO

[Driverman5777]

I love the hell out of my car. It has had more than its fair share of problems but when it comes down to it, I have not driven a single other car that has been a worthy replacement. If it blows it blows, but as of now shes my baby.

[CoolMs3]

after you get the stang, we will do a 60 roll, see how you feel then. Don't get me wrong I've been a Ford guy from day one, I Love stangs but theres just to many.
I know alot of stock MS3's have blown maybe from tard drivers or poor maint.
I'm avoiding after market tuning for now and feeling confident.

[GoSpeed3Go]

im sure there are cases of stock 3s blowing, but i cant remember the last one ive seen in quite awhile and im sure its not those owners fault one bit, they probably never went wot or overrevved one time, drove like a dick showoff or botched their own oil change ever. its funny when i see all these people whove had there car for less than a couple of years and have already replaced practically the entire exhaust and induction system on a late model car that is controlled by a very sophisticated computer, figuring they will play mazda engineer at home on their computer and use their vast knowledge to tune the car to run flawlessly in all situations. props to those who do.

[jahman]

To those of you who think that standbacks are safer than APs. You seriously must not have been around too long, have you.

Maybe some of you people who have no fucking clue what you're talking about shouldnt be posting your speculations about this part that part, this tuning device, that tuning device. It does nothing but causes panic on a catastrophic scale. I'm tired of it, and I know I'm not alone.

You're not alone, this shit is getting really anoying, but I will say it only causes panic in other people who dont know what they're talkin about so fuck it...

[Lex]

Stock MS3s take the car to the dealer and don't write in forums. Everyone here has some mods - does that mean the mods break the car? In some cases for sure. In all cases - we'll never know since we don't know how the stock ones perform.

[Scatt Nasty]

Rofl in the beginning it was mostly SB users that were blowing, and people stated the AP was the "safe" route due to cobb making preset maps.

NGRPLZ you guys are retarded.

[cpolly69]

?'s I asked myself when I debated getting one or the other - (keep in mind I"m just talking about using the sb on the car w/ the fcf and nothing else)
How far can you advance the timing on ap? How about the sb? Before you run into DTCs that you can actually read and eval on what you are doing
Does flashing chips several times have a long term effect on them vs just tricking the sensors that interact with them?
How lean can you push afr with the ap vs the sb? How rich?
How much can you play with the throttle plate mapping to your (expert) opinion vs. the fcf?
I'm not saying it's not the best tool out there, but how can you say it's not more dangerous?
I'd say the best answer to why do mzr engines are blowing up left and right is ap users using the experimental tune of the week

And as far as "being around for a while", I bought my car in Jan08 and have been reading this and other forums since then- I am the type that reads a great deal before jumping on to conclusions or the band wagon of the week - and I can also tell you that I've been around long enough to know this place is full of "experts" on everything and minions that follow them like a religion, just like every other forum

[Driverman5777]

been around plenty long... not saying they are safer. just that there are less parameters for people to fuck with. this huge AP blow up trend seems to have happened since ATR... I think that's not coincidence. If you tune your car like a jackass with either system its likely to blow... however a perfect tune with the SB is much easier to achieve than ATR.

[jwdp54]

only things i used when i had the standback was the boost table, fuel table and maf. easy to use. not saying the ap isn't but i've never messed with it.

[nue]

So, anyone got a link of a stock car blowing?

[_Toxic_]

If u dont know what your are doing when tuning your car dont tune it!
Its a shame cobb releases tunes/APs for this car...

if it was a good tune you should just plug it in and thats it! You should not be able to change anything for u self, Why dont they have like stage1 , 2 ,3 that u can buy that already have the right maps? And like stage1 has catback with it, stage2 downpipe and so on, ready kits. Thats because they havent developed their tunes fully yet. Not saying cobb is crap, but dont make tunes so u can change anything yourself.

When people start to fiddle with all the parameters them self and maybe have no clue what their are doing, thats a way to disaster.. I wish BSR came up with PPC tune to this car.

lol... good attitude i suppose.

[mps_owner]

I have worked out the problem and have a very simple solution.

Engine Failure = (too much power for rods)

too much power for rods = (modifications to stock car)

modifications to stock car = (going above and beyond factory tolerances)

factory tolerances = (designed by large TEAM OF REAL Qualified engineers)

REAL Qualified engineers spend all day designing parts to work reliably over many many kilometers.

Now how do you all think you can tune your own car and make it more powerful ?

Its like trying to build a second story on top of your home when your house is not structurally strong enough to hold it.

there we go I solved the problem.

next time you push your car past the limit, just refer back to your engineering class and the mazda engine specs thats publicly available. oops wait, hold on....none of that is available. Oops hold on, im no mazda enginner and i didnt work on the mazda engine.

damn.

Considering stock motors blow I'm gonna have to call BS on your theory. Saving money is always higher on the list than quality engineering. That's just a known fact of being a part of any business. You can make any product last forever, but you won't make a profit off of it. Part of designing something mechanically involves creating a safety factor. If the rods are weak their safety factor is extremely low which again is probably due to budget constraints. J
ust because they are mazda engineers doesn't make them god of engines. We already know they fucked up the pcv system pretty bad. If you think just b/c someone is a GM/Ford/Mazda/etc.. engineer makes them a good engineer you have alot to learn.

[cpolly69]

no one knows any real numbers here to make judgments about what's going on - the only people that have a clue is Mazda & that's with the folks who most likely had mild mods or none at all and took their car to them and it was covered under warranty - and if it didn't fall into those circumstances - didn't someone just push it too far anyway?
I spoke to a tech. at one of the 2 dealers I'm around who had recently returned from Mazda's training - (and this is just what he said) he said that blown disi mzr engines are not even a blip on the radar for Mazda, the number of them that has been serious failure is very small - he said the pcv, turbo smoking issue is well known and discussed in his classes and that Mazda was working on a solution for it - he said Mazda's biggest concern right now is the RX8 engines - he said those things are truly blowing left and right

I am GTFO .. just have to stock it out first and sell my speed parts ......

[gsrtype1]

Like Lenny said our blown motors are not statistically any worse than others it just gets blown way up on these boards. You can blow your motor with a tune if you got an aggressive tune and you dont monitor your knock and drive it like that everyday. The best thing for longevity for our motors is to tune yourself with the Standback or the AP (if you know how to tune) and then constantly monitored with a Dashhawk rather than getting a shelf or dyno tune and hoping it works out. Thats what I have done and after 62,000 21psi hard modded miles my engines still uses no oil and is beastly .

[Darksun280]

Theres no official list but guys who have been on the site for a while know of stock cars that have blown. One was even a cx-7 owned by a soccer mom.

Well its easy for Lenny to say that cause well there are thousands of cars made so if you talk in terms of percents everything always seems really big or really small. If I was to say 1% of the worlds population will be wiped out tomorrow by some diseases some people would be quick to say thats not alot of people but when you hear 1% is actually 67 million people that would be the same as everyone in Ny state, Ny city, New jersey, Connecticut, and Delaware not existing anymore....

[Driverman5777]

yes however a small percentage on our cars actually are a small percentage... especially when it comes to speed6's... they only made 8k of them.

I think maybe what happens is people start to get alot of kr and don't know it (of course some get more than others) and over time this weekends the rods like Hal said. Cause who has blown with this setup tuned with Standback with meth and consistently monitors kr in tune and makes adjustments. Thats why I think people should street tune themselves so they can fix there tune as needed. And of course stock turbo as big turbo weaken the rods as well..
