Max safe boost for Stock N55

[Evice]

oh Jesus. ask Vishnu for clarification rather than fighting.

did they just increase boost, used meth and race gas, or did they also involve their tune? Simple as that.

my feeling is that, since they do not use mechanical or external anything to boost, they have to use their tune to get the turbos spool up more. I am just looking at logical point, which might be wrong.

they likely turned their piggy back into a high teck boost controller for the experiment, seeing as they wrote the coding, they likely started with no fuel mapping to see what the parameters were for the engine before adding fuel.

so yes, if you want to be technical, they used a tune, but not in the way you are thinking. The way they used it will be more like a glorified electronic boost controller. The type of information Daniel was looking for.

This thread should have been over as soon as Calvin had spoken. But for some reason people on this site have to be petty about things. And there is a lot of misinformation in this post. So Anyone else reading it. Please don't take much of it seriously......

Daniel, manual boost controllers are not popular on these cars because the computer will compensate when it sees the additional boost. Thats why there are so many piggy back/flash options. If you want to be different and run just a manual boost controller, I think you will find it tough to hide the boost from the pressure and knock sensors, to keep timing up.

Most piggy backs do that for us already. Why reinvent the wheel?

If we didn't re-invent the wheel, we wouldn't have these piggy backs and flashes available.

Yes the ECU would attempt to compensate for altered parameters, but that's a good thing, and something cars have done for about the last 15 years. That's half the reason why Manual Boost Controllers work. They sense extra air, so they add more fuel to keep things safe and within emissions territory, but you can then turn the controller up even more and it will step outside of what the ECU can compensate for eventually.

Daniel isn't trying to make a new safe tune, he doesn't care what check engine lights he throws, he just wants to know what the engine can handle before it becomes "lean"

which by the way, i believe PROcede does when it's cruising to save fuel... so this isn't a new theory or unheard of idea for all those who seem confused by the situation.

You CANNOT force more air into an engine an not add more fuel (thereby maintaining safe A/F ratios) without causing damage.

NO he didnt, if you read what he typed, they increased boost while useing alternative fuel, there is nothing posted about adding more fuel to the system. He might have monitored the AFRs that way, doesnt mean he added more fuel. All he stated was increased the boost. Get your quotes right, did you do this or did he?

You need to learn more about boost before you start making calims like that, its blatently ignorant. (no offense, but obviously you have no clue what you are tlaking about.)

There is absolutely no way anyone upped the boost to 17psi without any tuning... even with race gas. I can almost guarantee that a piggyback was used.

correct. shiv was referencing his testing of the procede v4 on their n55 135i shop car. please read these threads for more info, if you think they just "up'd the boost" without any tuning

For fucks sake, did he mention useing a tuner at all???? No he didnt, end of fucking discusion, go learn to read.

You dont just start out designing a piggy back system without going through the basics first, and adding boost without other modifications is the BASE standard for starting a tune. Go educate yourself because your making your ignorance show when it comes to modifying any kind of motor.


Reguardless if this is my first BMW, modifying cars isnt brand specific, as you might think on your first modified vehicle. Dont welcome me like your a guru and im a rookie when you have no clue what your talking about.



But, alas, most people on thier first time ever modifying a car are ignorant as well, so ill regress back to just giving people like yourself a big -laugh out loud- and be on my merry way. Have fun with your inadaquet second hand information, where ill stick to getting mine from the source - Vinshu. Good Day.

Lol, u may not be a rookie to cars but your obviously a noob when it comes to tuned bmws. So again elcome to e90post. The search feature is your friend.

Great book! Read it... come back then tell us you think you still know what you are talking about.

This coming from a kid who drives his parents car, and apparently not that well so he fucked it up, and then was going to lie about it to insurance:

YOU should stop fronting like you know anything just because you sell shit on the forums kiddie. You, dont know shit.

Daniel, how is it that every thread you get involved in almost immediately turns into a shitfling? Could it possibly have something to do with your personality?

Didn't you get banned once from here? Did that teach you nothing?

You might want to start asking yourself some questions about how to better relate and get along with people. It might have positive ramifications for your life as a whole instead of just on random boards...

Ok ,right now, 14-15 lbs without supplemental fuel (like meth)
At about 15 -16 lbs the car goes on fuel cut if you sustain that boost. You need to understand that this is a new engine with a new ECU that we are just starting to work in it so there's not alot of people that now the info your looking for and the ones that do now it don't want to give it out this early in the game.
I'll tell you , I've modes alot of different cars but this is been by far the most complicated one so far because the ECU has so much control over everything in the car, and I mean everything.

BTW, the PROcede is not just a boost controller, it actually has timing control, so when Shiv "tuned" his car he didn't just turn up the boost.

That's a spot on evaluation. 12 years in the force, may be he is tired, not everyone takes it the same.
