Default Experience using Syked ECU Handheld to tune VE?

Hi! About a year ago I purchased a Syked ECU Handheld (Syked ECU Tuner) for my 2005 Touring edition PT Convertible Automatic. It was the low horsepower tune so Kevin gave me a GT H.O. tune to start out with as a baseline.
The software is very hard to use and comes with no instructions and not very many people are willing to share their tuning secrets on how to tune the srt-4 motors with similar software such as SCT tuner or HP tuners.
Anyways I put on a high flow muffler on the stock system and now the VE table needs to be tuned to compensate.
I started tuning the VE table using fuel trim data harvested with an LM-2 device and logworks software. While logging, I turned the DFCO off and stayed out of open loop so the data would be precise. In open loop the fuel trim data sticks to one value and it doesn't make sense and it skews the numbers. So then I multiplied in the fuel trim correction as a % into the VE table using an excel spreadsheet and pasted back into SET and flashed the car. I have done this a few times and now my LTFTs are all mostly less than |3|.
I have a 02 bung welded into the exhaust before the cat so I can get good wideband data. What I am guessing I should do is to disable closed loop so it is on open loop all the time, drive it and record 02 data, then compare that table with the power enrichment above stoich FA ratio table. The problem is is that the PE table has different axis set for the RPM and P-ratio than the VE table. So im guessing i would make logworks export a table with data matching the PE axis and take a % error there. Then plug it into MATLAB and somehow change the axis and manipulate the data to fit the VE table axis so I can multiply the % fuel error into the VE.
Also, how do I tune the transmission? SET has no tables for it. Unless maybe the desired torque table affects shifting? Idk.

I am looking for people who have had actual experience tuning these types of ECUs and would be willing to share some of their techniques, any help would be appreciated.

i'm not familiar with the syked tuner.. or PT's.. but...

i can tell you with my ford junk i had 2 issues when learning the fueling.
i needed to filter out data where the ECT was under 180
i needed to filter out all data where the injector PW was under 3(usually this is decelerating and can affect things

"lasota racing" has good tuning guides, and forum.efidynotuning.com/index.php and eectuning.org are pretty amazing forums but not mopar. maybe they can point you the right direction?

IDK what you're the tuner you're using even looks like or if anyone here actually uses one. i make stickers, not a tuner. so just the village idiot trying to assist over here.. just a disclaimer

besides the fact the guy is an idiot, he's just too busy being a fat beaver looking political troll on FB to help anyone. i'd sell his shitty tuner and upgrade to, well, pretty much anything else.

can't get ahold of him? have a look why:

^and it's only because they're stuck with him. of course people hit him up when they need something. they bought his junk and now their cars don't run right. DUUUH


nobody on here has ever posted a success story with his stuff. ever. anyone that used to push his product now seems to scurry away... for good reason, IMO. like.. buy my system and then figure it out yourself!
