Stage 4 foo!:mad:

whhoaaahhh hold on there, you cant release that "thing" yet....give me a few months, I cant afford too much, already ordered spool kit....and its not cheap.

Sorry, had to post, need to watch this thread.

another thing to think about is that the older turbo probes, i beleive ran the same block and pistons as our car, i would have to check the book at work, but i think so. I know the NA version is the same, as linux has discovered. therefore there is proof that these motors can handle boost. Any engine can handle boost if tuned properly. check this turbo out.

Yes the only difference is the ecu.

The Racing Beat Exhaust has a little to do with the extra 10 HP.

Nope, that exhaust you showed is an actual performance exhaust. The exhaust that is in the MP3 is just for a "mellow" tone. It even says so on the website. They ONLY power difference is the ECU. And yes, I have said this like 5 times now, the ECU's swap with no extra connector or anything like that. They just swap out like a plug in the wall, they are the same connections.

Flying Miata dynoed a P5 with both ECU's. They only got about 4 hp and 4 Lb/Ft. at the wheels with the MP3 ECU. There is one more difference between the ES/P5/LX motor and the MP3 motor. It's been discussed here before. That's the intake manifold. The MP3 does not have VTC (variable tumble control). That's quite a bit of restriction due to the blades and the cast in lip on the upper part of the runner that the MP3 does not have. Probably one of the reasons that the few people that have the FS-ZE intake are noticing such a difference. I've modified my upper intake and it made a noticeable difference.

Those are the two differences between the MP3 and the rest.

I don't see why it's even really that important, when you have the fact of a difference in timing, and know that causes a problem in turbo applications.

Howdy, I'm a lurker from another board and just came over after Patrick (Linuxracr) was asking us some questions about his engine.
I couldn't help but notice that you guys are encountering failures with only 6-8 psi of boost. Do these cars have knock sensors on them? This ECU swap, if it's only pulling enough timing to drop 4hp, it's probably not going to make too much difference. Has anyone slapped a different intercooler on these cars? That should be more beneficial than an ECU swap. What about fuel pressure?

At any rate, make sure you tuners have the coolest intake charge possible and don't be afraid of timing, just balance it with the boost levels you're running.

Detonation kills 90% of turbo cars. Avoiding detonation and high temps with a good tune is what will give you power and reliability. Anyone messed with water or alcohol injection? Better yet, anyone tried propane injection?

The different Intercooler could be a reality soon.

gahhhhhhhhh I dont know if I should do the ECU swap or not. damnit.people say its the timing. then people say noo dont worry bout it. I dont know what to dooooooooo. I just need to get the spool stage 3 upgrade which I was planning on anyway

And NASA engineers said that one tile probably wouldn't make too much of a difference. Look what happened, little things added up to one big thing, then BOOM. The less little things you have going wrong, the less chance you have of that one big thing going wrong.

I fully understand man.
the reality is no one has reliably found a way to work a turbo with any protege yet for over 6 PSI. Our ECUs, all of them need to be out ruled by another computer controlling timing, fuel and injectors on its own. The slight difference in timing between the cars will only buy you 1 PSI at best and that is not a 100% reliable. But like Ben said when your $4000 motor is at risk anything is worth a try, especialy if it doesn't cost you anything.
Another one is unless you add $1000 worth of guage to any turbo kit you will never know when you have knock. In our cars with a decent exhuast its too loud to distinguish slight knocking. Hell one member had to be driving through a tunnel before he heard it at all and I have yet to ever hear any but I know it is there.

With an MP3 I Fallow StutterC and run only 5 PSI max now, not to mention it runs so rich for saftey that the performance is a joke.
Even though I have better octane fuel then he can get I figure thats just safety not a go ahead to increase boost.

Just waiting for someone to come out with something hard core and reliable. I am also trying to find a mazda tech to dump the MSP program into my ECU and then I can just run better injectors and they can actualy tune a MSP ecu know.

 

[NC_MP3]

I have asked serveral dealerships about reflashing the MP3 ECU with P5 or MSP settings. They all say it can't be done. The can flash in updates they get from Mazda, but not the whole thing.

So if anyone knows for sure that would be great.

 

[1sty]

I thik its time to offer a tech a big discount on a TV and maybe we can get some real answer, also NC. A local dealer mentioned that the MSP will have alot of adjustablity in its next software version but the MP3 and regular proteges will continue to only have diagnostics. Just letting you know

 

[Adam3482P]

Fu*k breaking into the docks to steal the radio's. Lets break in ourselves and steal all the MSP's ECU's. They will replace them

What are you talking about, people stole the radios out of the MSP at the docks?

 

[Adam3482P]

no It happened to the MP3's in canada originally.

 

[1sty]

I take it thats why you guys had the 828 instead of the 919?
