Hey guys about 1.5 months ago i tuned my car with a VERY well known person in my area.after that i recently bought a tactix cable to view/log my car and it turns out i have this
https://docs.google.com/spreadsheet/...Wc&usp=sharing https://docs.google.com/spreadsheet/...lE&usp=sharing https://docs.google.com/spreadsheet/...UE&usp=sharing 2012 wrx hatch Grimmespeed EBCS catless DP tsudo AEM intake catback straight pipe w/ resonator my tuner says its either bad gas, the FIRST log was with 91, then i purchased 93 gas and i still have it, im pretty sure -2.1 is a bad thing then he says or there is to much restriction, im not sure if resonator has alot of restriction. so im going here to show you guys what do you guys think about my logs, my grammar is really bad i know.

Did you reset the ECU after putting in 93oct gas? Also looks like you have some boost hunting/oscillation going on.

Your AF learning #1 is a little outside of acceptable range. Check for boost/vacuum leaks (either smoke test or pressurize intake tract and use soapy water.
http://forums.nasioc.com/forums/show....php?t=2205161 Also log manifold relative pressure to see boost. You only logged target boost. That's not what boost you are seeing that is what is being called for. |

Resetting the ECU will get rid of the learned knock reduction. |

I see thanks for the feedback, just spoke with Shawn (my tuner from churches) he says it's ok the ecu is always adjusting boost and the afr from 2k-3k is good , and my ad learning #1 is in acceptable range(he says more then 5% ) is bad . ?? Any feedback on what he is saying

Where in the rpm should u start the wot pulls from. Does it depend on the turbo your using? Im running 16g on a hybrid and when road tuning i started pulls from 2500k..

And all I know is, even on 93 octane and one step colder plugs, I can get fine learned knock correction if I try a WOT pull in 5th starting below 3k, (don't do that. I did it once because I was curious.) |

Alright guys, I've had my wits end with talking to Shawn from "CHURCHES" i have to disagree with people that recommend him.
But now i feel like i wasted 500 bucks and about 200 bucks worth of gas traveling to him. I will find a new tuner. Last edited by bobssecrtsn; 05-22-2013 at 12:33 AM. |

The learned knock comes in at the same load cells everytime, so it's something previously learned. Reset the ECU and drive through about a tank of gas. Leak test intake tract first as previously suggested. Fix any leaks, if any, then reset.
