Dh a/f accuracy.

Even if the DH is off a point, doesn't laloosh still have an unknown problem in 4th gear during the multiple shift runs?
 
Yes, this car does run lean when banging through the gears on the stock pump.

Yes you need a upgraded fuel pump, even if it is a questionable one.

Yes I was wrong.

Yes I blew my engine.

You guys win/ were 90% correct and I am ******.
 
Just pasted from the other forum. I havent gotten a chance to really figure out WTF happened, so this is the best I can do..

Ill give you all more details once I work everything out. It was late and cold and I dont have time to jack the ******* car up and see what happened.. There is oil everywhere.

I was on the power hard but hit shifts at 5900.. went into the next gear and heard something that sounded like it was from the turbo. Exhaust instantly went in a HUGE cloud of smoke and debris (blown seals?). Next came what sounded like shrapnel coming down the exhaust and being tossed out. I tried to pop it in neutral and at that point something happened to the turbo. Almost at the same time I heard a big pop/boom and a s*** load of noise from the engine. Immediatly after that the car shut off, I tried to restart it and it wouldnt (at about 30mph at this point). NOW the steering stopped and the brakes went hard and no longer worked. I had to use every bit or strength i had to pull the steering wheel enough to turn into a open lot at the Acura dealership. The brakes were not working so I used the ebrake to get it to stop.

The steering is SUPER difficult to use and the brake pedal is so hard that I could not even push it down. There was oil that shot out of where the little oil tap thing goes (sorry im tired and upset..not up on my terms right now), right by the intake... the intake is covered in oil. The back where the turbo is has sout everywhere as well as oil. Oil is dripping down from engine somewhere.

Car wont crank in the slightest bit.

What do I think happened..We have been talking on the other forums about this car running differently when mashing the gears and just doing a pull. I went through the gears and up top I believe the car leaned out. Caused detonation and fubared a rod or two or 4. Im sure something happened to the pistons and I KNOW that the turbo seals are ***** and I believe that parts of the compressor wheel scattered down the road.

The car behind me pulled in to ask if everything was fine and said that pieces of shrapnel and s*** where coming from everywhere.
 
Ive been using aem uego's for years with a 100% success rate. Ive always had a bad taste in my mouth about the dashhawk. The idea of it it way cool, but if its giving you inaccurate results then its a HUGE waste of money. I cant say for sure just yet but from my preliminary tests it seems to be reading atleast .5 points off from my uego. As far as video goes I dont see that happening. I dont even have one. I will do some comparible testing to Chris on monday when I put my fmic on. I do know the dashhawk is telling me I am running a 1.65 60ft., and i know that is far from true. My tires are going up in a blaze of smoke through 3 gears. My best trap so far is 112.5 but Im only holding 16psi to 6k where Chris is holding 19psi.
Ill let everyone know how things are going.
 
welcome to the blown some s*** up club..........
The Kia rio rental I have is making more power than my MS3 right now.......
 
Alright.. I think I have kind of figured some of this out. Work with me here and correct me if im wrong.

This is all on stock s***:

ECU has multiple tunes. At least one for when it senses economy driving and moderate highways pulls (passing).

And another when you are banging through the gears and using the performance of the car.

Now we all know the car runs rich and when we are cruising along the highway and go to do a pull it usually results in some black smoke. So IMO, the ECU adds more fuel to help the driveability of the car and to gain a bit more fuel milage.

When you bang through the gears from 1st or 2nd (remember stock power, everything) the ECU senses this and pulls timing and some fuel to lean the car out for more performance with the loss of economy.

So people with MBCs and TBE have no problems when they do highway pulls because the car is a bit rich and if anything they help the car run a bit better in those situations.

Now people with MBCs and TBE, when they bang through the gears the ECU again pulls timing and fuel, but it shouldnt! The car is sensing stock boost and proceeds with its normal ruitine. Where it should be adding fuel, it isnt because we have tricked it.

We all also know that these cars dont like cold weather and the tune in 5th gear blows. So mate the cold weather with the bad tune and the fact that you start from a low gear.. the ECU starts its magic, normally it would be fine but since you modded guys have BCD, when it gets into a dangerous zone it doesnt cut because it is being fooled into thinking they are stock conditions..

Ill elaborate more on this once i get a chance to really see the damage.. Kind of dreading pushing it into the garage, etc..

Darksun- are we the only 2 members of the blown MS3 club so far? I think we should make on of those pages online where you can buy tshirts with logos and s*** on them and write like "I blew my $10,000 motor and all I got was this bad tshirt.." or something..
 
Problem is my dealer doesn't want to admit it's blown. They told me the noise that resembles a bag of screws bouncing around in my motor was a bad turbo. New turbo and now there scratching there heads avoiding my calls leaving me messages that say "Mr Gittens Mazda usa says we should try new injectors so where gonna try that. we need your car for another 4-5 days" God damn order the create motor so we can both move on with our lives.......

I think its pretty normal for ECU's to cut fuel between shifts. At least on A/T cars, I dunno about manuals.

On the CX7 the engine pulls a lot of timing in between shifts. Easily 10-15 degrees, or whatever the dashhawk measures it in. Full acceleration usually reads 5-10 in spark advance on the dashhawk. At gear shifts it easily dips to -10.

I doubt that information helps the situation at all, but its just an insight as to what the engine is doing, granted the CX7 definately doesn't have as an aggressive tune as the MS3/MS6.
 
just to let you know when mine went it was 17 degrees out and sounded like metallic capt'n crunch........

It was about 25 degrees here but weather.com said it felt around 15*. Dew point of 5* ad 14mph winds.

Basically Im just trying to say you either need a good tune and add fuel at 4800-5300rpm on the stock pump or upgrade the pump, even if the options are limited. Even then.. it is running a bit of a risk and you might want to tune it to add even more fuel in that range.

Also, be sure to get some GOOD cold weather spark plugs. Plugs and a pump are really 2 things that need to be done. (bike)
 
My brakes also dont work. The pedal is super hard and immobile and the steering is beyond difficult.

Any idea what that is from?
