    Issue with Trim Error Tool

    If you're tweaking your tune you don't have to zero out load comps. If you're following HCIF guide it is stated you only need to rescale MAF if you did something to alter flow across the MAF sensor I believe with examples otherwise you should only need to tweak load compensations depending on...

    Issue with Trim Error Tool

    Thanks, I'm on a non stop quest for knowledge and learning. Lately trying to hone my deep understanding of Exhaust CAM Retarding and Intake CAM Advancing (How/Why/What to adjust for my slightly larger CAMS and +1mm Oversized Valves) as well as Manifold Wall Wetting Compensations (specifically...

    Issue with Trim Error Tool

    Don't waste your time logging latencies. 1. The basics a. How much data are you using (how many lines of data in your log)? b. Is the car FULLY warmed up when you start logging? c. I assume you're using access tuner? d. Did you zero out load compensation tables and...

    EJ257: An Overview of the Changes Over the Years (2004-Present)

    I know I've seen D25 too. I am not familiar with heads other than the W25 and when buying oversized valves, cams, springs, seals, etc. I remember seeing on iag website of head work they had N25 from Type RA/newest STI and went to SOA website and cross referenced part number the heads were...

    EJ257: An Overview of the Changes Over the Years (2004-Present)

    I'd like to know what is the difference from the W25 to the new N25 heads

    Cobb OTS stage 1

    I took the test first time and went straight to tests and passed no problem. Yes and no as far as Super Knowledgeable. It's as easy or as complicated as you want to make it. Heres a VERY ROUGH AND BASIC layout for adjustments in a "COBB" style layout, lol Stage 1 - Closed Loop Adjustment...

    Cobb OTS stage 1

    Stock tune is icky, lol. Ok it's garbage there, happy I'm honest now? In reality the stock tune: Cons - It's not good in a sense of everything Pros - You have to remember they have emissions standards to follow and certain safety things in place (customer putting in 87 oct vs 91 oct vs 93...

    Subie newbie from MD

    I monitor different things depending on what I'm doing but then again I also tune my own car with Cobb AccessTuner. As far as fuel trims the information it is giving you is the percentage of correction to obtain a stoichiometric air:fuel ratio based on O2 sensor feedback in comparison to the...

    THE E85 HEADACHE

    I see you only have 1 post so I am guessing you signed up and posted and never checked back. I don't know what you could mean by E85 headache? Doesn't sound like you tuned it as you said you have a protune so if not tuned correctly take it back to the tuner. If you tuned it yourself I can...

    Tip-out knock

    I don't see where you even logged feedback knock, you only logged knock count which isn't actual knock just that the knock sensor picked up a noise and it associated it with cylinder 4. It could be the ping of the butterfly valve closing against the throttle body or as you let off the gas...

    Fixing Torque Dip

    Thank you HolyCrapItsFast I will try that. I know it isn't much knock but still I don't know what amount is level for concern with stock block and internals, so I am just trying to keep it at 0 as best I can. Maybe I should see if it still does it when I turn on my water/alcohol injection as...

    Fixing Torque Dip

    Thanks Raven32, I've read that before I got my FPR and that is also where my boost source for the FPR is tapped off of. As to issues with knock maybe HolyCrapItsFast or someone can take a look over these logs and see if they notice anything out of whack I made tabs at the bottom as per...

    Fixing Torque Dip

    IGOTASTi Thank you for the warm welcome. HolyCrapItsFast Thank you for the response. Makes a lot of sense, and well...while I don't "feel" the dip on VD, I do feel the "dip" in the stock turbo running out of breathe as it gets in the upper RPM range. This should be somewhat remedied...

    Fixing Torque Dip

    Hello I'm new to tuning, been doing it for about 3 months now trying to obsessively learn best I can. I signed up here because I love holycrapitsfast tuning guide (the best I've found), I also use the ones by Cobb and Badnoodle. I have trying to figure out why I get a dip in torque and HP...
