Holley Datalog viewer improvement
It pulls in your datalogs (.dlz included) and can optionally move them to a folder of your choosing and rename them automatically with some intelligence — even including the tune name if you want. Everything runs local on your machine, no internet needed (unless you want it to pull historical weather, including DA, for your logs — yes, it does that). And it never touches your original datalog — it creates and stores its own copy, so if you trim too much on a plot or something, you can always reimport.
You can customize the tune info card with whatever fields you want, drop the
ones you don't, then search all your logs on any of those fields — including ones you create. There's also a customizable report card that can pop up each time you open a log. For me there were critical checks I made after each run: injector duty, lean spots, overboost, etc. Green = all good. Red = better have a look.
It works on profiles, so you can have one for racing, tuning, dyno — or if you tune a lot of cars, one per car/engine. Each profile keeps its own layouts and settings.
I'm pondering offering it for sale, but before I invest the money I want more eyes on it — features that might be nice and ones that suck. The website shows some of it if you want an idea: www.tunelyzer.com
I need 10 folks to do some testing. Looking for:
- Log import issues — you should be using EFI V6 logs or TermX V3. It might pull in older unconverted files, but no guarantee.
- Feature requests — what would you want that I haven't thought of?
- Bugs — what can you break?
- Timeslip verification — it's an estimator, and if you overwrite predictions with your actual timecard it learns your car and gets better. I want to know how well that works across different setups.
- Math channels and warnings — I include some, but can build out whatever, or make your own and share them.
If you're truly interested and willing to take a few minutes to learn it, DM me and I'll send an installation link. I can only handle 10 initially, but if some of those 10 turn out not to be real testers, I'll work down the list.
