Hey can you send me your profiles.xml file in the data folder so I can try to see if I can get the profiles bug you saw with 14 profiles?

First off, big thanks to bbarnhill for this awesome software!! It seems like most of you folks in this thread know this software really well so I figured I'd try and pick your brains. I installed an AFI turbo setup a month or so ago and I just want to see if this power increase looks about right to you, both runs were done on the same road and in the same direction.

That would be a good question for the others on this forum to chime in on. I drive a GT500 so Ive never even driven a Subaru (dont throw rocks)
I used to have an Evo (again dont throw rocks). I got invited to this forum to share VD with the rest of you and have been here 2 years now. |

8psi should gain you 80-100whp. Basically 10-15whp per psi is pretty standard.
What's up with the boost and afr plots? If that squiggly one is really the afr you better add like 30% fuel in boost or you're gonna melt your internals. |

The solid blue line is the afr reading from the stock car with no mods. The squiggly red line is the un smoothed boost curve from my 3rd gear pull. The lc-1 decided to go a little wonky after I filled the tank before doing the run that is why its not shown, so I think I hit the re-calibration button without knowing it(working fine earlier). Earlier in the day doing second gear pulls(with lc-1 working), I was logging 11.1 afr by redline, extra fuel was added from 3000rpm and on. I also have a meth injection kit installed that will be used once this is tuned properly(well as best as one can with a piggyback ecu) on 94 octane. |

ahh. you purely running wastegate boost? with no really boost controller?
if the boost was really oscillating like that (8psi, 4psi, 8psi) it would feel like a bucking bronco. as far as the AFR's go.....i would just err on the side of rich, especially if you dont have an EGT gauge. subarus like richer AFR's. i've been running 91+meth for almost 10 years and even with 2 meth nozzles running pure methanol i still just run 11:1. |

You are correct Phatron, I have a vacuum line running from the turbo to the bottom nipple on the ewg. Would a boost controller help insmoothing out the boost? The boost looks a lot worse then it really is since it's not smoothed in VD,the actual logworks screenshot looks a little different.
Ok, thank you for the advice! A lot of the research I did steered me to 11.1, I will now adjust my tune to get to 10.5, will that be safe enough or would 10.1 be better? I do have an egt gauge and it will be set up hopefully today. |

Strictly waste gate boost, like you have it hooked up, should be about as smooth as you can get. It's purely mechanical.
Any boost control system would be fighting like crazy to smooth that out, it would probably get worse. |

Yeah I agree 100%. I went through some other logs and I think this that one was an anomaly(or I hope it was), though it is also the one that show the most increase in power. I did a second gear pull the same day and the boost curve looks a whole lot better. I'm going to do some third gear pull in the next few days to see what they look like. Oh and I'll be shooting you a donation tomorrow for this awesome software, without this I'd be lost right now
Hmm that's not news I wanted to hear. I rechecked the vacuum line from the turbo to the EWG last night and discovered I put a 4mm line on my mistake, I then replaced it with a 6mm line. Would that make a difference at all? I've also done some searching and it seems that the EWG valve sometimes can flutter, is it possible that is what happened in that log? |

The EWG can/will flutter if you're using an EBCS. When you're using a vacuum line connected directly it should be rock solid. None of those boost curves look normal at all. The size of the line won't make it flutter like that.
Do you have a boost gauge? Does it look solid on there? Can you take a video during the pull? It seems like this could be an issue with your logging software or the boost sensor. |

Hey Xluben. Yes I do indeed have a boost gauge, its digital so it moves fairly quick but the numbers look pretty solid on it. We're dealing with another cold snap right now(highs of-25*c high,lows of -34*c without windchill) so pulls will be done once it warms up a little but I will for sure get a video.
I have most of my boost sources running from a vacuum block(meth boost sensor,bpv,boost gauge map sensor, aux map sensor), would that have any effect on how my map sensor sees boost? Sorry for the 20 questions I'm just trying to rule things out, the car runs great both on and off boost. |

No, I'm using an aftermarket Map sensor that came with my gauge. My generation is MAF based and does not have a MAP sensor that I can datalog. I am using the OEM 16bit Jegs 96 pin ecu, and am using a piggyback ecu to adjust timing and fuel. The vacuum block(top right in photo) is getting fed from the #4 runner where it is Tee'd into the brake booster line before the check valve.

Well, I'm pretty sure that's your issue, but I'm not sure on the best way to route it all with your setup.

Ok, that's where I'll start then. I'll pick up a Tee after work, try a different place to get my boost reading and hopefully that smooths things out. I'll report back with the results and new VD plot.Thanks for the help!

I did another 3rd gear pull the other day after switching my boost source and the boost still seems to be fluctuating. I've gone over my set up with a fine toothed comb and can't find anything out of the ordinary that would cause my boost to do this.
The only mechanical things that come to mind are: 1)My idle air control valve is leaking under boost. The jdm turbo models have a 1 way valve and my NA version does not since it is only supposed to see vacuum. I have ordered the 1 way valve and will do some pulls once it arrives and is installed. 2)My wastegate spring is too weak since I am running such a low psi. I will be pulling the currant spring and going the next step up +/-4.35psi -> +/-5.8psi to see if things smooth out at all. Quote:

Maybe go buy a cheap mechanical gauge from autozone. I think they are about 20 bucks.
Hook it up and zip tie it to the wiper or something. It should show any fluctuations. I think some electronic gauges have a "smoothing" built in to them. Tap in to the boost feed for the map sensor you are logging. You should feel the boost jumping around like that, those are some big changes. Do you have a nice steady vacuum reading at idle? I'm wondering if you have a bad map. The iac shouldn't matter, it just bypasses the throttle body, both sides of it are in the pressure side of the system, correct? |

also, i'd go buy a bunch of clamps and clamp all your boost/vacuum lines. at the very least use some zip ties. i dont see anything on your lines. |

As for the IACV, being that I am an older subaru, the valve is attached to the actual intake manifold by the #3 intake runner. The older JDM turbo GC/BD models have the 1 way valve behind the same IACV as mine (although different pipe routing) so that is why I'm going to install it and see if that helps. If it doesn't, then I can at least cross it off my growing list of probable causes. Quote:
The second system is a combination of datalogging components from Innovate Motorsports - Lc-1(AFR), SSI-4(TPS,Maf V,coolant temp,rpm), Lma-3(EGT,aux map sensor kpa, IDC, ignition timing) and the MTX-D boost gauge(http://www.rallysportdirect.com/Inno...ght-Gauge-52mm). The map sensor came with the boost gauge(shows it in the link) and does not have an option to be scaled. Oh,that pic was taken once everything was installed and after testing for leaks. Since then everything has been clamped and/or zipped, but I will check them all again though. Last edited by V8Slayer; 02-12-2013 at 05:42 PM. Reason: spelling :S |

I went to a local Mustang dyno today and logged the pulls. Here's how VD and the real dyno compares, though I guess a more accurate comparison would be to set the SAE stuff in VD and probably remove the driver weight? I just left the settings I normally would if I had done a road datalog and it's pretty close:
Today's run is the lighter blue and red. The other was from a previous run I did last year. |
