Knight sports, Boost FD

[leefitz]

Hey, could do with some advice on my boost. What\'s the safe level to be running at? The car is running a Knight sport ecu. Don\'t have much info on that so have no idea on what way it controls the fuelling etc. Everything else is standard apart from non sequential turbo setup and manual boost controller. Obviously I want to pull what I can form the engine but don\'t want to put her at risk either.
 Your words of wisdom would be great.
 Cheers lads

comes down to whether or not you have stock injectors... is so, I wouldn\'t go over 1bar, and that\'s with excellent flowing injectors too

[leefitz]

Cheers man, yea stock injectors with 56k miles under there belt so wouldn\'t say there fantastic. Is there truly an additive you can run though the car to clean the injectors? Can you run larger injectors in a car without ecu and mapping? That\'s something i assumed you couldn\'t? Currntly the cars full load boost is about .65/7.

[pigeon]

You could contact knightsports and see what the ECU is mapped for. Thats what i did with mine when i was running a knightsports ECU.

[leefitz]

Think I went to do that before but had problems. How much was your ecu different compared to a standard ecu?

[Indian]

they could map it for 500psi.. you dont have the injector to go over 1bar safely ... if they tweeked it id prbably even stay under 13psi. max injector is maxed injector.  Personally, i wouldnt trust fuel injector cleaners, that just me.. Id rather spend the extra instead of building a new motor.. 56k injectors isnt much at all either.. but who knows..

[leefitz]

Cheers for that man. Mite open the boost up a we bit more then but not much. I remember reading somewhere before that some of the ecu\'s are tuned also to deal with decat too? I was on there website but couldn\'t make head nor tail of it to get an address to ask about my ecu. Who do I contact?

Fair play Indian, cheers. I tryed to do that on the I phone but couldn\'t get it sorted. Home in a week or so to to the laptop. So much better than these phones

[Indian]

Hope you dont think I was trying to be a prick. Just dont know anyone else to help with the situation but the people themselves.

Sorry if it came off that way..

[leefitz]

Hell no man. I appreciate it. Iv the email sent already too. Looking forward to hearing what they say.  Get this clued up, plus another few bits to sort and that\'s prep sorted for another drift day

Soreally there nothing that fancy about the ecu then. I\'ll not be changing anything apart from boost to maybe .8 bar or so, no higher really. Although, what\'s fun control?

[PDale]

fun control = fan control?

rev limit : cancelled
hmm that sounds worrying, do they really mean its just been raised from stock or can you rev it until your engine explodes. lol

[leefitz]

I was under the impression that there was no rev limit anyway? But yea sadly under a few occasions iv had her rev to she reves no more. Bad practice I know but in the heat of the drift sometimes it\'s not beneficial to change gear at that time.

[Vell]

I\'m pretty sure it\'s just a confusion between "rev limiter" and "speed limiter".
