BEGI Turbo Update Part 3

[smp3000]

293!! Holy crud Christ!!!!

Once we're able to reprogram the ECU and get those injectors I'll go for the dyno and do my tuning. Until then I'll go easy on the 8psi. But things also have worked much smoother onc eI started running a half tank of 101 octane in each fillup. Expensive, but my car is like my GF so she's worth it.

Chris, on the dyno when we heard the ping the computer should have been open loop. In that situation, the voltage clamp won't actually do anything. So I wouldn't get your hopes up. Remember that on our first test drive on the road we couldn't hear ping. That hood's pretty well insulated plus I think we'd mixed the toluene by then...

Once we're back from CA, we might be interested in swapping ECUs for a while so we can try something on yours. Nothing to the ECU itself, but we need a pseudo-MP3 to test it.

I'm sorry that Corky marketed the kit as an 8 psi MP3 kit from the beginning. That may have been true for a sea-level Texas car, but I don't think it applies across the US. We're doing what we can.

The Track Dog is on the dyno right now. That thing sounds like the world is ending - seriously mean. We're having trouble with our dyno, but I've seen one partial run with 288 whp/278 ft/lbs at 12 psi...

Ok, let me know and we can see what happens. The I was looking at the dynos and it looks like where the advanced timing takes over is where the ping started on the dyno...I think.

I've been up most of the day so far so i don't know what I'm talking about anymore.

And no worries about the 8 psi thing. We'll get eventually, just have to be patient.

Although, at 5 it is fun as heck, at eight I think I might pee my pants.

Update: 293 whp. Yeehah. Time to go to the track.

Keith

Good job guys...How about I just trade my MP3 for the Track Dog for awhile while you get things tested.


Meanwhile on the drive home I get pulled over..."What do you mean a picture of dog is not a legal license plate??? That's not what the dealership told me!"

I'm still trying to figure out how it is a design flaw that the car squeaks...

If it was designed properly, it wouldn't squeak.

And what terrible transmission problems? People blew out their tranny's by abuse. Tell me a six puck clutch is a reasonable idea for the street and I'll show you a blown tranny for it. How is the tranny garbage? It is suited just fine for the car.

I don't know of anyone who runs a 6 puck on their protege. And people who blew their trannies didn't necessarily do it because of abuse. They blew because the tranny is crap. My tranny was showing the first signs of dying (with grinding during shifts), so I brought it in and had it rebuilt. But my nissan truck never had tranny problems...and I drove it for years.

Also, I know a subaru guy who had a FOUR puck and his tranny is fine.

Now, yes the wheelhop is a little bit of a problem. But Mazda doesn't design a car to raced in the cold, they design a street car...My CRX jumped just the same. And it was stock.

I don't know...I've never been in a car that wheel hopped as bad as a protege.

I haven't heard about the radio failure. And the pressure crack I'm sure is an isolated case. You are the only one I have heard of with that.

My mp3 head unit's display was fine one day when I went into lunch. When I came out and turned the car on, the display was all distorted. I wasn't the only one. And I've never messed w/ my stereo. But that's Kenwood's fault, not mazda's. I know a few people who got bum Kenwood products.

As far as the service goes at a dealership, that has nothing to with the reliability of a car. That is the dealers fault and not the manufacturers.

True, but certain manufacturers have better and more knowledgeable service techs at their dealerships.

 

[Kooldino]

I swear, knock is so gay. I'm seriously now awaiting FM's re-programmed ECU and larger injectors.

Now up to the mobile to get some 101!!!!

This is what I've been saying all along. FM, ARE YOU LISTENING? THIS IS WHAT WE WANT!!!

 

[1sty]

There already working on it

 

[Kooldino]

There already working on it

Hope so, I need it ASAP!

They been on this for well over a month now. However no one can even guess how long it will take at this point.

 

[JunkPunch]

The MAF is in front of, or upstream from the turbo. So it does not "see" the boost.

Huh? Is the engine getting air from someplace other than what is going past the MAF?

I'm missing what you are saying.

Basically, the stream starts at the filter and goes up to the throttle body. So starting with the filter, it goes: filter, MAF, turbo, intercooler and throttle body. The air from the turbo doesn't go through the MAF at all.

The reason the MP3 has knock is because of the the advanced ignition timing. I haven't heard of anyone getting knock in the Protege 5.

And the FM has been on this for longer than a month. They were working on this when I went and got my base run dynos over there. It takes a while to reverse engineer what the factory has done.

Mazda is helping out as much as they can. Visteon wouldn't even let FM know anything about the ECU. So, soon...I'm wanting this just as much as everyone else.

The air from the Turbo does go through the MAF, thats the only way into the system. Th eMAf simple measures air density so it know underboost how much sir the turbo is thowing into the engine since that air must go through the MAF.

The MAF is the tube thing with the little waffle inside, the little thing that measures air flow, etc. It does not see the boost.

Where else is the car monitoring air flow??

Boost = more air through the maf so the car know exactly how much air per area it is getting if that number is under 14.7 then its vacuum. If over its Boost. The car only knows how to match the fuel in the ratio of vacuum and not boost, hence the fuel issue. But the car is very well aware of the amount/density of air, boost, that it is being fed.

The car "sees" the air/fuel ratio through the o2 sensor...It sees anything other than 14.7 and it adjusts accordingly.

If the MAF saw the boost then we would have issues as mentioned above, the car can only handle 15% more air flow through the MAF. The MAF does not see the boost.

oh a protege?

 

[colin949]

wait i just came on here, but is the 293 whp on a protege?

No that is on the Track Dog...Flyin' Miata's racercar, a Miata.

I'm not sure what you mean by "saw the boost". The MAF is seeing a huge increase in the volume of air when the turbo is generating boost. It is pulling the air through past the MAF. If the MAF reading is not used to adjust the fuel/air mixture, what is it being used for? Nothing?

 

[colin949]

some day there is gunna be a 293 whp mazdaspeed protege

 

[colin949]

doesnt matter what kinda of protege
