So i modified my stock file for a little more boost and advanced the timing just a bit the strange thing is it will spike 21 hold for 2500rmp -3500 rpm then fall down to 11 psi i have attached some screen shots of the tables i modified i m wondering if i screwed up somewhere havent had a chance to log
02 a4 1.8t temporary car till i get the s4 up
Replaced N75
Vacuum and Boost tested whole system
Brand New f21 franken turbo
New Diverter
Pretty Much replaced everything looking close to failure

I have no logs because I have a boost gauge (makes things easier)

Umm yes, so what you saying requesting 1.2bar at 1000rpm is possible on a k03??? |

If you want to be a wise-ass, then up to you, I never even looked at what LDRXN was at 1000 RPM, I was just questioning your saying that his ldrxn is too high for a K03. Is an FT F21 a K03 to begin with? |

his initial post was K03 check with the op, and even if it is a frankenturbo that requested isnt exactly sane is it? I dont know what your issue is with me but you seem to have some chip on your shoulder and searching through your posts dont actually have anything of any value to say anyway. Wise-ass I wouldnt say so but in this case I think that pertains more to you than me  |

Can you increase your KFMIOP axis? You need to get that torque map under control. The highest axis point is 145 and you are showing load of 200 in some places. Take a look at ME7 Tuner Wizard. http://nefariousmotorsports.com/forum/index.php?topic=1371.0title=Post your KFLDRL. If this post gets moving it could be re-titled and moved to the Project Car section as the 1.8T Frankturbo F21 tune. Get ME7 logger going. Search the board. Mark P's template is what you want to use to diagnose your problems. |

No bueno. Way too much boost too early.

Actually you can request as much boost as you want as early as you want, but then observe how this boost is reached and then fix low rpm range if you want

I suppose, but stock LDRXN ramps up pretty agressively to begin with. Personally, I don't think there's much to be gained from too much requested load that early.

There are really only two concerns
1) Positive deviation (if you request too much too early)
2) Throttle cut, or the PID pulling WGDC during ramp (if you request too little too late)

Just a couple notes here...
I'm pretty sure 11psi is cracking pressure for those turbos, my guess is limp mode. Get some logs.
No offense to masterj or anyone else, but IMO, you can't rely on an excel workbook to tune a car for you.
Big picture stuff, when you change one value it usually will affect other things. LDRXN for example does not just affect desired load but also has influence in %MDMAX and %LDRPID via rlmax. Not relating to the OP's problem, but just something to think about.

its weird if it was limp mode wouldn't it keep it at 11 when ever trying to do a pull because when i go to the next gear or stop and go through the rpm it spikes 21 then after drops to 11 i will be logging tonight |
