How to Scale VE tabe for more boost
 

Planning to run around 10psi soon, so i was wondering how to add more cells for higher boost? Now VE table goes up to 230kpa.

Thanks, Taras

Here's how you do it, step by step:

1. Ask a stupid fucking question on an internet forum
2. Get flamed for asking a stupid fucking question
3. Cry to your mommy
4. Hire a tuner who knows what the fuck they're doing

Until you understand enough about your ECU to realize how stupid your question is, don't touch a damn thing.

and 230kPa is 19psi....

How about you go and do these three things:
1. pull our pants down
2. bend over
3. take a 2x4 up your anus.

i thought it was not relative to atmospheric pressure. so its more like 130kpa.

It says something about scaling VE map in the MSpnp manual when going over 6psi but does not tell how to do it exactly.

Boost (Tuning for it)

When setting up MSPNP on a boosted Miata, you won’t have to change very many settings other than properly tuning the VE and Ignition tables for the additional airflow and load. Start with making sure your VE and spark tables go up to the maximum amount of boost you plan to run. Since boost is gauge pressure and MegaSquirt works in absolute pressure, this table will help you convert the amount of boost to the maximum KPA level. These values go just a little above the maximum boost setting.
Boost Level Suggested Top kPa Bin
Naturally Aspirated 100
5psi 140
10psi 175
15psi 210
20-21psi 250



The MSPNP is equipped with a 2.5 bar MAP sensor, so the maximum amount of boost it can read is 21 psi of boost. While higher amounts of boost will not damage the sensor in most cases, it can damage your engine if you do not tune for it. The MSPNP will not add any more fuel above 21psi to compensate because it cannot detect the extra air, which can result in dangerous lean conditions if you boost beyond that point.

Since MSPNP is a speed density system, you do not need to recirculate the air in the intake. If you want to you can go ahead and install a monster blow off valve and vent it to the atmosphere without worrying about having it throw off your measurements.

so because it already goes up to 230 i dont have to change anything?

Do you think everyone would be giving you shit if you did?

do you plan on running more than 19psi?

nope.

the text you copied from the MS manual, if you read it with an ounce of comprehension, answers this question.
It also does not say you need to re-scale if you go above 6 psi anywhere in there.

i am just confused about relative pressure and absolute pressure.

2.5 bar MAP sensor.


1 bar = 14.7psi = 100kpa. This is what the atmosphere's pressure at sea level is. The sensor in the PnP reads 2.5 bar. You've got to subtract 1 atmosphere (bar) from total kpa, because "boost" is pressure in the manifold OVER atmosphere.

I use this webpage to convert kpa to psi:
PSI-KPA Pressure Converter

Then deduct 15 from psi result (eliminates atmospheric pressure) to get boost pressure

then go to wikipedia....


0 KPA = pure vacuum. 100kpa = atmospheric pressure = 14.7psi ABSOLUTE pressure


Absolute pressure includes the pressure of the atmosphere. Relative pressure is the pressure RELATIVE to atmospheric. when someone says they are running 10psi they are running 14.7 + 10 = 24.7 PSI absolute

Remember: PSI = english units KPA = metric.

So hire someone.

why would i hire anyone. maybe the first thing you do is hire someone when you have a question.

Actually, I use the search function, spend an hour or two reading, and (most importantly) refrain from making stupid shitty threads about the topic I am trying to learn about. The threads I do usually make are summing up what I learned and asking for clarification and/or confirmation.

You literally said, in your OP:

"I want to run around 10psi soon, so I want to add more cells for boost, how can I do that? The current map is scaled to 19psi."

If you don't understand why that is stupid, I can't help you, and my original recommendation stands.

dickish comments like yours dont make me learn more. Seriously, is it that hard to be a little bit nicer even when people ask stupid questions?

Until I'm getting paid for it, yeah, it's really hard.

I'm getting sick and tired of listening to your shit. You keep pushing me day in and day out, and eventually you'll push me past the point of no return. I don't give a fuck who you are or where you live, you can count on me to be there to bring your fucking life to a hellish end. I'll put you in so much fucking pain that it'll make jesus being nailed to a cross in the desert look like a fucking back massage on a tropical island.I don't give a fuck how tough you are, how well you can fight, or how many fucking guns you own to protect yourself. I'll fucking show up at your house when you aren't at home. I'll turn all the lights on in your house, leave all the water running, open your fridge door and not close it, and turn your gas stove burners on and let them waste gas. I'll turn your air conditioning on high and open all the windows. I'll turn your cable box on and order 20 pay per view channels at once, and I'll pick up your phone and dial a pay-per-minute sex line in Japan. I'm going to run your utility bills up so fucking high that you can't pay them. You're going to start stressing the fuck out, your blood pressure will triple, and you'll have a fucking heart attack. You'll go to the hospital for heart operation, and the last thing you'll see when you're being put under in the operating room is me hovering above you, dressed up like a doctor. When you wake up after the operation, you'll be scared for your fucking life, wondering what I did to you while you were being operated on, wondering what ticking time bomb is in your chest waiting to go off. You'll recover fully from your heart surgery. And when you walk out the front door of that hospital to go home, I'll run you over with my fucking car out of nowhere and kill you.I just want you to know how easily I could fucking destroy your pathetic excuse of a life, but how I'd rather go to a great fucking length to make sure your last remaining days are spent in a living, breathing fucking hell. It's too fucking late to save yourself, but don't bother committing suicide either...I'll fucking resuscitate you and kill you again myself you bitchfaced ------. Welcome to hell, population: you.

oh, man... It really looks like you need some medical attention. Go see a psychiatrist. You are one of those people that will go on a shooting rampage because his toast was burned on one side. And with all those guns you have there in Texas you really should take some anger management classes. You are an angry guy and its not healthy.

but i have to give you credit for pretty interesting story you made there.

i bet if you search certain blurbs of the above post, you'd find it elsewhere; on this site and others....

Yeah, its like that around here. Search, inform, then ask questions.


Hustler and his E-thugging.
He really is a teddy bear after you get used to him.

On that note... i feel lazy and dont want to search... where do i find best sounding blow off valve? I need more PSHAHZSHAHSDHSHS....:fawk:

I just don't have the energy to be as creative with my work schedule lately.

There is one thing we do not tolerate here, and its your piss-poor ------ry coupled with pre-op tranny, trans-gender bullshit that we will not tolerate. Unfortunately I cannot disclose my location because I'm on assignment at the moment, so I can't deal with your bullshit. However, I can assure you that you're only a plane-ride away from making a stylish new coat...but I seriously doubt there will be enough material to wrap around these pythons. I highly suggest you adjust your fucked up, shitty attitude, maybe even consider getting laid for the first time in your life rather than tossing another life-failure into the gym sock your mom bought you in middle school that you're still wearing resulting from remarkably low testosterone, ------. Then, maybe with a little luck your family won't have to release your dental records.

Jesus christ people. The whole FLAME THE F*CKING N00B OMG stuff gets old (except for hustlers psycho rants, they never get old). We have all been there before, granted he could have searched.

OP, You really need to read the manuals over and over and over until you start to understand the different aspects of the MS and how it works. You might even want to hire someone to give you a base tune to go off of, and tinker from there. Baby steps. You'll blow your shit up for sure if you just go cranking the boost up right away.

<- flame away.

stfu and go back to eating cheese in your mother's basement and whoring mirc for child porn.

You told me you would never tell anyone.

I do know the basics pretty well. I pretty much just got confused about the relative pressure and absolute pressure. I put everything myself on the car wired all myself and not going to pay anyone for anything. I am going to go baby steps but i will do it myself.

And as for you, psycho! You really need help and i am not kidding. And i can tell you are very uncomfortable with your sexuality. And if you would come to my house you would leave it in a squad car. You should really watch what you are saying. You can get in trouble for assaults you make.

no one cares about your failure of a life. No one loves you, take the pain away.

The only virgin here is you. Gee, you sound like a 14 year old.

I am married btw.

If Hustler showed up at your house you'd be leaving in zip-lock bags.


Most noobs just don't know any better when they come here. You on the other hand are just too fucking lazy to press the search button or you know, Use google...

Here, I'll help:

That link will give you all the info you need for megasquirt VE Scaling..

Oh, that helped so much... not.
So much for being welcoming. And if that dipshit is being all tough and shit online it just shows how immature he is. Gosh, internet forums are just sad. why cant people just be nice to people who ask questions, even stupid questions.

No you just have to be all tough and show that you know more than noobs do, but really just because you have 8000 posts does not mean shit.

and yeah:jerkit:

Because, contrary to popular belief, we don't sit around in front of our dual monitor setups with our PM inbox open waiting, just waiting, to answer EVERYONE'S questions as SOON as they post them like some turbonewb tech support line.

We are here to help those that atleast try to help themselves. Do some searching, figure what you can out, post back asking for more explanation, clarification, or just a confirmation on what you think is right. Be prepared for a flogging anyways.

Think of it like a marathon. Have you seen those folks that stand on the side of the road handing water to the runners? They're not paid to be there, they volunteer to give a measly 4oz of hydration to someone that is putting forth incredible effort to reach a goal.

We are the gatorade table people. You are the runner. Now put your fuckin sneakers on and find the search button.



People like you make them that way.

Well, contrary to YOUR belief we're not here to hand feed people like you. I joined this site new myself and learned the proper ways of web forum. Search, think, then post. In that order.

You're going to get nowhere if you expect you can just be lazy and have someone hand it all to you. Why not just pay someone to do it for you if you've got no ambition to actually get off your lazy fucking ass and do something for yourself.

:2cents: Take it, or leave it. Nobody cares to help someone who won't help their self.

Perfect execution.

I want to make dirty, dirty love to this post.

Ok fuckers, I've run a marathon in every state and quit counting when I hit 200 marathons (no shit, this is true). Consequently, I know the value of volunteers, there is no marathon without them.

So.... when I install the MS I bought from Brain, cut me some slack, as much research as I have done, I'm sure I will ask some stupid questions too :fawk:

dude, all you people that are hatin on this rushin dude, you're all a bunch of low-life fucks. seriously.

for the first time in my life, it really makes me sad to be a part of the miata community. and it makes it even worse that this is a concentrated part of the community, that i am trying to put my car and myself into.


i got flamed on my first post by some jackass, who can only talk shit on an internet forum. just like this hustler douche.
i agree with you guys, do as much research as possible. but damn, there is a lot of shit on here.


you guys who talk about how internet forums work, ya'll are all retarted fucks. i participate in 5 different car forums pretty regularly, and none of the posts ever receive comments like they do here. usually people are willing to help and just answer the same questions over and over again.

so go ahead and talk your shit about how your gonna come and rape my dog and shove a spoon up my asshole, either way tonight i'm gonna sleep like a fucking baby. i really wish we all lived in the same little town, so i could walk up to your fucking shit and chin-check you when you needed it.

idk why in the fuck you 'elite members' would want us to subscribe to this forum. we would just be paying for a bunch of losers to write stupid worthless shit.

you remind me of the torrent sites that i download off of. probably a bunch of 107 lb nerds with 4 in wankers trying to act hard.

so as of this post, why don't some of you losers send me your address if your so bad. then my little half asian ass will go to MIT and learn how to land a fucking bomb right on your forehead from antarctica or wherever.






IOW...just shut your fucking mouth if all your gonna do is put down people who are trying to learn how to fix their shit!!! let the other constructive people on here who are willing to help answer their questions.

let the flaming begin. my name's, Alex mothafuckin Balmat.

#'s 919-820-0564. anyone who has the balls, fucking call me up. don't write your bullshit on here.

girls please.

lol, good stuff.

lmao...


pours himself a cup of coffee and crosses his legs.

"yea, it's in pen!"

hahahaha

I just read this thread finally for the first time, and I found it quite entertaining! The new guy asks a pretty stupid question (actually really stupid) and some tuff guys go off on him! Was it rougher than it should've been? I'd say not. This is the internet, a place to act like a badass even though you're not. I liked the "if hustler came to your house you'd end up in a ziplock bag." What kind of "I watch too many scary movies" shit was that? I don't know hustler personally, and I don't give a shit about him or his life, but he drives a fast miata and that's why were all here. As for the pussy that said "talking to people like that can get you in trouble." People like you are responsible for the downfall of this society with your political correctness and non slurred vocabulary. If I wanna call somebody a dirty wetback or even use the word "retard" to describe someones physical condition, it is my right as an American. As for internet threats, I don't take em seriously, it's all fun a games in a sick twisted way.

Yeah, thats right, we all should have guns and if someone says something to you that you dont like, just shoot him. :jerkit:

I'd strongly suggest you go back to those forums, then.

umm...no...because:


Without all these "elite" members you speak of (I call them experienced, because that's exactly what they are) this forum would suck.


Without you, this forum would be just as great as it was yesterday.


Thank you for your input though.

your welcome

Just a hint:

Proper grammar, use of your shift key, and refraining from leet(text) speak will get you a long way here.
