nobody that has been running meth consistently has blown up, also nobody with a cdfp upgrade has blown up full throttle either

Yes, stock cars have blown.

Ya mine had the CDFP upgrade as well. Also my deal had one about a week ago that blew up because 2 injectors stuck open and bent 2 rods.

d00d, jarod, i'm sorry man. that sucks. good luck with the dealership.
worse comes to worse, you can have p3 build your engine

lmao

I thought the thought behind the BSD was that it prevented oiling issues with cylinder #3? How many of the engines have had issues with cylinder #3? (This one was #4)

I am just going to wait until monday and see what they decide. Then take my course of action from there.

Before getting out of hand, I think most people can agree that this was probably due to a manufacturing issue with the engine. There was very little load to speak of on the motor when it let go.

damn japanese in hiroshima can't build anything right

j/k lol

What I'd like to know is this: has anyone who has a knock warning at below 3-4 ever blown an engine?

Until it can be shown that excessive knock is not the cause of most of these failures I'd say it's a MUST-HAVE in these cars to have a knock warning when you hit 2.

PID data?

ok here is another one, has any speed6 or cx7 blown a engine?

I don't think Jarod did anything extreme for the engine to go out. It just doesn't make sense with all this said blown engine with mild mod.

balance shaft *cough cough*

Quite a few speed6's have blown.

Balance shaft should have anything to do with Cyl #4.

i don't care which cyl it was. When you find me a motor that has blown with the BSD complete then i will drop this theory. Until then i will stick by it. Also seems that there are more speed3's this happens with but then again there are more speed3's on the road than ms6's

That's my theory as well (IIRC you even PM'd me about one of my posts in the past and I told you about it), and I'm obviously a huge proponent of doing the BSD for safety, but to blindly state that the BS caused this as well or that a BSD might have prevented it is silly, IMO.

well im just saying it may have very well aided in it. Or maybe it did not cause it at all, however i don't buy half of what people say on these boards... "i was cruising at 2k and motor just popped" No it didnt.

could it be just a lemon? i mean cars are massed produced... a couple of them are bound to be shot.... just a thought. thats why mazda only gives warn. to 36000 ha.... btw sorry about your loss.... either way it sucks big time...

You know i was just as big of a sceptic as you and i never would have believed that this could happen until it happened to me. It seems it does just "pop"

so now we talking about gen coupe? lets get back to blown motor.

Wasn't there a 100% stock speed3 with blown engine? So we can rule BSD out..right.
I have over 52k now with minor bolt on, I love driving this car so much that I'll be piss if this car blows...

hell with it, if it goes it goes...like palerider said.

I'm gonna try to enjoy mine

Jarod, hope you get your car back soon.

100% stock would mean balance shaft not DELETED.

So no you can't rule that out until we see a ms3/ms6 with BSD and a blown motor.

Which dealership?

^This.

BS = balance shaft

BSD = Balance shaft deleted

Stock car doesn't have the BSD.

Delete that bitch

ha, thats a good one.. Those guys are cp-e's neighbors right? The ones who dont even know how to set a boost controler... Then after they blow up your car they steal your mods and sell them. Then they deny it and fuck you oit of THOUSANDS of dollars. Yeah, thats where i would go !
If mazda decides to screw you, call PG and get a built motor, remove BS and beat this piss out of it !

that sucks man. hopefully you took it to lou fuz and none of the shitty bommarito dealerships. what rpms were u at when u shifted?

I tend to agree

I have never seen an Australian MPS3 do this lean closed loop positive boost thing.
Ive said it before.. as soon as we see boost it goes into open loop, and drives the afr towards rich. Maybe your silly American emissions tune is stuffing your motor?

i can haz australian ecu?

If I boost in part throttle it stays around 13 AFR in closed loop...usually around 12 psi or so.

Some people are just in plain denial. These engines suck plain whether stock or midly modded...plain and simple.
It's not a matter of if...it's when.
When someone blows with the bs delete then I guess there will be no more speculation.
BTW...bs delete is permanent isn't it. If so, and it blows you can bet that engine won't be warrantied as soon as they pull off the pan.

In an ideal world...an AP will be able to rip the flash off an AU ECU, email it to us in NA...then profit...well, at least more fun, and maybe less headaches...

hmm how many aus cars have blown?

Sorry, im not sure which planet you guys live on, but deleting the BSD isnt going to stop detonation... nor will it stop you from blowing this engine.

Failures such as rod/piston letting go at non wot is fatigue. Long term detonation will weaken the rod from the inside. This is why i push for people running bolt on's to invest in a meth system long before they go ape shit with engine tuning. Ive seen these cars knock stock.

you guys can speculate all you like, but this is long term detonation finally doing its damage.

For future persons reading this, monitor your PIDs closely with a dashhawk or other device while tuning or trying maps out. 2 weeks of logging can save your ass. If you are knocking on meth, you got some serious fucking problems.

deleting the delete?

Well, i have run some pretty hot maps while developing MSF maps.. 100's infact... ive had not one issue. I have straight whored this fuckin car... so.. ive easily placed 14,000 of hard AP mapping miles to this car and no blown engine.

The one thing i do different is i dont go smacking WOT with a fresh map.. i drive the car 60 miles normally, little to no boost and act like a senior citizen.. after that, i begin short WOT blasts logging AFR, knock, timing, BAT, and IAT... i study these and compare them to my other data.. i slowly get the map acquainted to the car, then beat the shit out of it.

Ive had my meth disconnected since October ( scared meth tank/odors were affecting my child ) and was set to put it back into action 11 days ago until the famous PTP plug nozzle failed me. Anyhow, if the map is safe, the car will be safe.. Just dont go out and beat the shit out of it once you are done flashing it. Check your PID's guys.

None that I have heard of...

how many mazdaspeed car are over there in oz?

Anyone want to look into importing an Australian ECU?
