I'm doing most of mine in 3rd gear as it is easier to get to redline.

Weight - 3530lbs
Delata Weight - 180lbs
Elevation 0
Rel Humidity 50
Air Temp 50
Wheel diameter 25.09 (225/40/18)
Gear ratio 1.521
Final Drive 3.9

The numbers like any dyno are just numbers. You should dyno stock and then dyno stage 1 and stage 2 and just pay attention to the deltas.

Yea I saved the data for reference so I can compare run to run, in fact I will go back and log stock as well so I have a full comparo. You have non-stock tires I presume... stock are 215/45/18. Minor difference on the calc.

Indeed on the tires. I'm swapping them next week and will try to get a dyno run before/after on the same road in near identical conditions to see how much difference it makes. Not expecting concrete results but we'll see.

I forgot to mention that you need to copy all the values over for a 5MT or 5EAT. roms are year and transmission specific.

I flashed this rom on December 18 after getting fed up with my etune knocking on wot runs and dropping IAM even after 11 revisions. I won't be able to install my wideband 02 for another few weeks, and I haven't adjusted the rom at all since I flashed it. As such, I've been taking it very easy while driving (been too cold/icy to drive hard anyway).

I've been checking LearningView every couple days (most recent attached), and it appears as though my goal of keeping IAM at 1.00 has been met. Once I get my WB02 installed, I'll start logging and making adjustments based on the newbie guides I've read here and on nabisco.

For now, my question is before I get started with all that, should I rescale my MAF? AF Learning appears to be a little off based on the LVs I've taken. My intake is completely stock with a Subaru filter installed 6 months ago. I've read conflicting views on here about whether or not the stock intake requires a rescaled MAF. If need be, I can do the closed loop scaling this week and then open loop next when I get my wb02.

Thanks for the help. -Andy

First thing you should do is a leak check.

The AFR Learning D on the 2007+ LGTs do vary. I believe it has to do with the MP compensation table. It will change AFR D depending upon how long you've driven in different regions of the MP table.

However, -8.70% is a lot. That's more than I've seen.

A WBO2 can help confirm whether or not there is a boost leak.

I attempted to start my LC-1 install last night but couldn't find a good place to run the wires through the firewall. It appears as though the nice rubber grommet that the regular LGT guys get is replaced by the clutch master cylinder in the 6mt cars. I'm going to set aside all day Saturday to do that. As part of that project, though, I did pull off and re-install my intercooler, and it may not have been completely sealed from the last time I pulled it off.

I also replaced my Megan HFC downpipe and Magnaflow catback a week ago Monday with an ERZ catless downpipe and the stock catback. After that, I reset my ECU and have been pulling daily LVs. My A/F Learning >40 g/s has never been greater than -4. And with the intercooler re-install and ECU reset last night, my A/F learning seems to be very good. I've attached both a 3rd and 4th gear pull and a current LV. It looks to me like I've got a good, safe, daily drivable tune here, and I very much appreciate that Mickey.

Once I get my wideband installed, I'll start seeing what tweaks I can do to the rom. My goal is to learn as much as I can over the next few months and then install some DW1000cc injectors, a fuel pump, and develop an e85 tune.

Notes: Logged parameters are based on NSFW post on how to make good logs. Atmospheric pressure was around 14 give or take .1 (forgot the exact reading).

Thanks for looking. -Andy

You should log the parameters that rtrbjason logged.

I need stuff like TD integral and WGDC. I don't need things like Intake air temperature and target boost. I can fairly accurately calculate IAT and target boost using airboy's spreadsheet.

Your car can make some more power. However, your current logs are knock free in WOT.

Do a log in 5th gear from 2000 to 3000 rpm. If that is knock free, do a log in 6th gear from 2000 to 3000 rpm. Remember... if the 5th gear WOT log has knock in it, stop.

Thanks for the quick reply. My main goal now is no knock although more power would be appreciated. I'll check out Jason's logs and see if I can get some better logs tomorrow.

3rd, 4th, and 5th gear logs attached. No 6th due to 2 counts of knock in 5th. I'll try to get my wideband installed today. Thanks for looking.

Edited because I'm an idiot and posted the wrong logs.

The 3rd and 5th gear logs are not WOT logs and you are still logging the wrong parameters.

Wow, yea, somehow I uploaded the wrong logs. I edited my previous post with the correct ones.

Mickey,

I've been looking through this rom because I'm just about to the point where I want to start making my own small changes, and I noticed a couple items that seem odd to me.

The Base Timing Primary Non-Cruise and Knock Correction Advance Max Non-Cruise tables use different values for the Engine Load (g/rev) column headers between 1.82 and 3.18 what's the reasoning for this? I'd like to use NSFW's Timing Editor to visualize the total timing, but am not sure it will work correctly with the way these two tables are set up.

Additionally, it appears as though you have edited the Target Boost and Initial/Max Wastegate Duty tables for Atmospheric Pressure Compensation from their stock values. To help in my newbie journey to enlightenment, could you please explain why this would need to be done and what I should log to determine if it needs to be adjusted for my conditions?

I've been spending a ton of time reading this forum and others about tuning and am nearly to the point where I feel I can start making small changes on my own. Thanks again for creating this rom and for your help with questions.

The column headers don't have to match. They just have to be monotonically increasing. I use an EXCEL spreadsheet to calculate total timing so it doesn't matter for me if the columns don't match.

You can use Airboy's spreadsheet to adjust the columns (without affecting the total timing).

I don't remember what I did with the compensation tables. I just remembered that I adjusted a lot of the atmospheric as well as IAT compensation tables. I think I changed it to be more similar to the 2005 type of compensation. I'll have to look at it again later tonight.

WARNING: There was a serious error in the timing tables below 1.48 g/rev. The timing tables below 1.48 g/rev were copied from the stage 1 rom which had the error introduced. Rev 002 of the stage 2 rom corrects the timing below 1.48 g/rev. Thanks to rtbrjason for pointing this out.
