GenPus do NOT loose boost at 5500

[texasboy21]

I hold 15.5psi till 6K RPMs, whats all this talk about falling on its face at 5500RPMs?

Most cars hold that boost to red line once tuned....
Try running 19-20psi of boost to redline, bit harder

Try looking at power figures, you'll see what people mean then

And logs > video of OEM boost gauge

[texasboy21]

And yes, slow Mazda is slow.

[snailD]

ok so here is the thing. that boost gauge reads 1psi high so it looks like you always hit full boost. second thing is that everyone on here says power drops off significantly around 5500 because the throttle starts to close on the stock tune. you can feel the power loss im sure, and when the throttle starts closing the boost will stop dropping. at the end you saw the bar go down, take another 1psi off that and you were probably at 13psi ish

[Big_Burd]

Lol, genpu

did not know you guys had a little boost bar that really tells you nothing.

[insomniacucr]

You can turn it off if you don't want to look at it.

[himurax13]

Hmm, I run between 22 to 24 at redline.

[texasboy21]

Word, thinks guys! I am **trying** to remain stock and keep the warranty, although I have started a collection of parts...

I did not know the gauge read a little high, and yes there is definitely a loss of power. Moar boost to come! Thanks for the input and keeping it civil!

Note: Tach reads higher than actual RPMs as well.

This^^^ on mine it's about 250-300 rpm high.

Note: don't believe anything on that mazda tach except the gas needle.

Shit and a little e85 will make that sketchy as well...

I remembered the sales guy telling me in an excited voice "AAAND it has a boost gauge!! 15psi wow!"

Today my boost gauge exists to tell me when I'm NOT in boost while grocery getting and while driving sedately on the highway. Ironic.

That's not right either. When mine says empty, I have 3 gallons left.
The MPG meter is a joke as well. Is it that hard to get this shit right?

Has anyone actually run out of gas? How much of the tank is unusable?

[rfinkle2]

Holding boost and making it efficiently are 2 entirely different subjects.

I wouldn't rev above 5500 rpm on the stock tune. The knock sensor on your factory tune is off above 5700 rpm.

The fuel gauge exists in its current state because of dumbasses who ignore gas stations and drive their car until 'E' is reached, and proceed to strand themselves on some deserted stretch of highway. Upon return to civilization they sue the shit out of the automaker for not magically providing them an extra 2 gallons of gas. The MPG readouts are optimistic at best, and flat out delusional at worst. Again, the current implementation exists because of dumbasses who want to feel good about saving the Earth - the same programming was probably used for the MS3 since it shares the same part with the regular 3.

+1

Stock gauge is not good for accurate readings. It reads pretty close from -5 to around 10 then gets optimistic.

Buy an ultragauge for a cheap monitoring device

[gearhead750]

Yet another Genpoooo fail thread. If some of you guys would just read a little you'd make the rest of the poo crew look a lot better.

[3Gee Tee]

Stock fail-gauge is fail.

[dantes5823]

Im not gonna argue about the gauge being right or wrong. But im just wondering this. Doesnt that read off the ecu that reads off the map sensor? The same sensor that the ap reads. Or is it just a lag type thing?

It probably does read the map sensor, but the # of bars and the visual scaling of that gauge could be way off.

I understand what you mean as far as it SHOULD be accurate, but who knows how they have the led's set up, the height of each led etc.

[SofaKingAwesome]

lol 25 viewing, this isn't gonna be pretty.

Confident thread title is not confident.

Don't know what you're talking about but my Genwon doesn't have loose boost either. My boost is mad tight yo.

[ThizSpeed3]

drive it, worry about psi after warranty

[Dash08]

It doesn't really have anything to do with boost levels.

The power curve just flattens out after 5500 on a stock tune. Basically, the motor just stops pulling.

[mrbeal]

I'm curious... why would redline be where it is if you will damage the motor if you rev to it? Seems to me Mazda would have to replace a ton of engines under warranty if this were the case. I understand the power falling off at 5500 but revving to redline is half the fun of driving a stick. Buying a car with a redline of 6700 and NOT being told by the dealer that revving to 6700 will damage the engine seems irresponsible to me. And, if they do tell you not to rev that high why in the world is redline at 6700?? Also, if the fuel pump can or can't handle the job why would they sell it that way?
Mazda "Lets sell a car with a redline of 6700 that we know will damage the engine if it's revved that high and a fuel pump that may or may not supply enough fuel to the engine and will damage said engine if the pump isnt up to the task..." not to mention the rear motor mount. WTF!! Seems to me Mazda is up to no good and anyone who buys a Speed3 knowing these things is a fool. I've found this forum to be extremely un-helpful and just plain rude. You fools are going to have to do with one less "brownie" here... some people just want to go to a site and educate themselves, maybe learn about something they don't know about. Well, you have pretty much educated me out of buying a Speed3. Just the fact that there are so many ignorant people on here buying cars that they know will be damaged if driven just blows my mind. Please, DON'T respond! Assholes

[NJSPEED3]

Typical poo stuff going on here.

[ganque]

Gandalf... he's always right.

[SRTie4k]

There is absolutely nothing wrong with going WOT to redline on the stock tune. It's not going to blow your engine up.

But that doesn't change the fact that on the stock tune the car still loses power between 5500 and redline. Peak power occurs right around 5500.

[2k4_8]

Is it just me or is this about to get good?

Rob hit it right on the head, the last 2 bars cover from 7 to 15 psi, iirc. Kinda hard to get a good reading off of that. Install a boost gauge or get an AP or other monitoring device, and be done with it.

i hate when people say they dont wanna void the warrenty with after market parts, please learn some info about how after market parts do not void the warrenty

well if you can't handle it here there is another forum that will be a lot more kind to you, mazdas247.

with that said finkle didn't say it was going to blow up, but the computer doesn't read engine knock past 5,750 which if something was wrong with your car, your engine wouldnt be able to protect itself up there. also there is no point going to redline if there is no power at redline.... why not shift just after 5500 where the power drops off?

wait, i just read you didn't buy a speed yet. maybe you shouldnt then?

Well aren't you just a little bitch...

[Voltron]

My Vtak engages at 5500. Wassup. And then if I dont let off, at 9k I flip into the backseat from all the powa.

[3Gee Tee]

^ Lol I miss my 8600 rpm redline too.

But I prefer torque.
