I have logs for most of the runs, is there one in particular you are interested in?

In a perfect world this would have been a Dynojet but I have a really good relationship with the owner of this dyno. I also have access to a lot of historical data from other cars that have run on this dyno, ultimately the A/B delta is the most important.

just the ones that are connected to the dyno charts you posted. I want to see what was different between them that explains the difference in performance.

The difference between the stock '17 header and OFH is a bit disappointing. That, or the 17 OEM headers are impressive.

I think the '17 header is actually very good for what it is. The graph's scale make the gains seem much less impressive than they are. Moving to the UEL header the mid-range came up as much as ~13 ft-lbs. The mid-range gains are noticeable on the street and help quite a bit at autocross. I also think it's important to remember this is on E85, pump gas will probably tell a different story.

I plan on heading back to the dyno with 91 in the tank and same day I'll test the factory tune, v3.02 Stage 2+ and v4 Stage 2+.

v4.0 Stage 2+ E85 w/ stock header log:

https://datazap.me/u/sathomson1/log-...0?log=0&data=1

v4.0 Stage 2+ w/ OpenFlash header log:

https://datazap.me/u/sathomson1/log-...9?log=0&data=1

I can post up a v3.02 log when I'm at work tomorrow.

Edit: @steve99 maybe you would be best to answer this?
I compare values by copying data from RomRaider into Excel workbooks and using Spreadsheet Compare to see the differences. You will need to switch ECU definitions when opening the 2.x vs 4.x roms. If they used the same definitions you could just use the RomRaider compare image function.

When you open a table in RomRaider, click edit > copy table to get values you can paste into excel. Save whatever tables you want to compare into different worksheets within the workbooks. Use one workbook per rom file.
Follow the directions for Spreadsheet Compare from here to compare the worksheets from the two workbooks. https://support.office.com/en-us/art...1-f15b3229f5d8

their are some cam timing and fueling adjustments as well between v2 and v4

the v4 is best on 93/94

if you want a dedicated 91 tune then log the v4 on 91 and pull some timing in problem load/rpm areas (where flkc exceeds -1 enough to keep iam at 1.

then you can set iam initial to 1 in your 93 tune and your 91 tune
if you want to go to that trouble

If you find the iam is almost always 1 then you could reset iam initial in tune to 1. The lower iam initial is to accomodate lower quality fuels like 91 as their is no dedicated 91 tune
I set mine to .9 and so far it's been hovering around .95 to 1.

Given my preference for editing in ECUFlash rather than RomRaider, is there any chance we'll get ECUFlash defs soon? I seem to recall someone here created some for the v2 tunes.

How to Convert any RomRaider Editor def to a EcuFlash def







Use the RR2EcuFlash.exe to convert any RR def to an EcuFlash def.
Conversion of 16 bit ECU defs may require some manual updates to make them 100% usable.
Copy the file created by the converter to your EcuFlash rommetadata directory and startup EcuFlash, then open the ROM for editing.
Application: RR2EcuFlash.exe


https://github.com/dschultzca/Defini...h.exe?raw=true

its a command line utility so you will need to run it from a DOS or command window


The full page on romraider here

http://www.romraider.com/forum/viewtopic.php?t=8449

you will generally need to correct a couple of things

flash method
mem model
and other initial header values
as per below in the ecuflash def after running the conversion utility

< rom> <romid> <xmlid>ZA1JF00C</xmlid>
<internalidaddress>8000</internalidaddress>
<internalidstring>ZA1JF00C</internalidstring>
<ecuid>A929703007</ecuid>
<year>2016</year>
<market>USDM</market>
<make>Subaru</make>
<model>BRZ</model>

Too bad the cam angles were not logged. Aside from the nice lump of torque from 4000-5000 its looks nearly identical everywhere else. With the cat removed and assumedly larger runner diameters, I would have expected more power everywhere. Then again... they were using the exact same tune. I would think that the optimal cam timing for each of these 2 headers should look a bit different as well. UEL vs Catted EL.

Interested on such comparison and if possible some logs.

I still don t get how there may be only one map for both EL/UEL... it sounds like a compromise
