I will get the STI I am tuning to do that, although I am over 18 near the redline ![]() LOL What was the setting? 10? Any logs?

![]() HAve you done a dyno?
It makes me wonder is the gas flow is slowing done and the car loses power????? |

![]() Of course at those levels, MAF doesn't have a lot of resolution. Getting from 4.7 to 4.72 is a decent jump in power. If you can run more boost with consistent timing and AFRs, you might have to resort to doing some pulls using some metric for calculating torque to see if you made more power.

How did your EGTs compare? I'm wondering if you were getting hotter exhaust gas temps or just more air moving through the motor. Thanks! Mike |

![]() That is a distinct possibilty. You can't use AFR as a measure of power either with changes to AVCS. If you are effectively raising the compression, you'll see the AFR go rich even though you are producing more torque. You need a dyno, and MAF signals would be a poor substitute.

![]() Just tuned an 04 sti.. Downpipe, drop in filter, stock axle back. SMC meth. Other tuners map made 261 and 288ft lbs. Dropped in AVCS map, 278 and 310! No other changes.. Then mapped it out the rest of the way and got 291 and 315ft lbs. 3 pulls into the meth map and I am at 310 and 350ft lbs. Almost done. Got a few bumps in the timing map to smooth... Just took a break to heat Potluck at work!
Not bad on this mustang dyno! Not really going for more.. That stock axle back is really holding her back.. Clark |

![]() Come on Clark. You're just teasing us folks that don't have a dyno (or even a (good) nearby tuner with a dyno). Just give us some more hints at your magic AVCS details.

![]() I am scanning the chart now! I got 315whp and 350 range trq on the methenol.. Thats about the highest I have done on this mustang dyno for a basic stock STI. That stock muffler really held this thing back. Prob could have made 320 and 380 if he had a muffler but he does not want the noise..

![]() One of my friend recently got a 2000 GC8 Impreza STI w/ AVCS. This engine is similar in parts to the STI 2001 bugeye.
Have anyone came across a vehicle like this? Is the ECU the same a a 2001? I haven't ask him to look @ the ecu because he is a strange guy. |

![]() I have passed on a conservative AVCS map to the sti owner for test. I will wait and see what he has to say.
My only other option is a JDM wrx w/ serious low boost issues becuase of the actuator needs testing. |

![]() Off the top of my head I would say no. One ECU (2001) has 5 plugs and the other 3 plugs. I'd also consider that at that time the AVCS may have been a open-loop system.

![]() Super duper AVCS......I'll have to remember that. If Clark posts his map, please be careful.
Clark have you ever heard the pfft,pfft,pfft sound at low RPM when the oil pressure is still pretty low? I'm not tuning anything until I get this noise figured out. |

![]() I have heard it on my car...dunno what it is but seemed related to low rpm, elevated WG duty cycle for me....

![]() I think he told me 5, but it is not like mine that is 3 connects that date back to 1996 ECU. This very strange on Subaru part, but hey, Subaru is strange.

No Advance: ![]() Full Advance: ![]() Note that in both graphs, WG duty cycles are at 100% from 6000RPM onwards. With little or no advance, you can see boost drops past 6000RPM. With full advance (40 degrees), boost actually increases to the point we can run 19PSI @ 7000RPM vs 16PSI @7000RPM with no advance. The car definitely felt weaker with more boost and full advance but you can see the AFRs richen up (fuel for the higher boost load sites has not been previously tuned as we haven't been able to reach those boost levels previously)... |

![]() Man I wished I did not read this thread.. Okay here goes.. Some uestions for phil and who ever has the info..
1. 02 wrx hydra what does your avcs map look like, beter yet what block heads cams did you use to create it.. Reason I ask is I have ver 8 heads.. that are capable of 40 deg of advance, have a diffrent cam profile then jdm wrx, ver7. and are bolted to a usdm 2.5 block 2. Also is there a way to see the cam advance physicly.. since the hydra can only do open loop.. maybe build a circuit and attach to the cam sensors. wich are used only to plug the holes in the heads?.. 3. Now that tuners have found power and can duplicate it will you unlock the map for end users and tunners.. power to the people ![]() Thanks for this great thread.. Phil this is not intended to drag you out into the open. sorry for all the spelling errors.. thanks george. |
