another tuning tool

[steveo]

it took way too much time to write.

i think it'll be really handy. it's very good at quickly asking questions about your datalogs

it also does some really neat stuff with tables that can come in handy, like comparisons and interpolations.

under the hood it uses bilinear table lookups just like most ECMs do so it's really good for taking a table from one operating system and mangling it into another one with a totally different layout.
anyway try it out and let me know what you think or not
64 bit windows only release for now
beta
might crash
probably some stuff doesn't work

looks fun - the ability to get tables from other OS is very convenient. i havent tried it yet but will in the near future. appreciate other enthusiasts taking the time to share their work with the rest of us.

some crash courses:

analyze log (example: VE)
1. press datalog and select log and hope it does not crash
2. press analysis
3. click table layout. choose your x/y data (MAP and RPM probably) and either type or copy and paste some column/row values in there, or press 'auto layout'. they can be any reasonable format, it'll figure it out.
3a. if you had to type them in, probably click SAVE so you can RESTORE it next time. this saves the layout for use across the tool
4. go back to the main screen and 'select data' (long term trim maybe)

done

add filters to suit, should be self explanitory

you can 'save' the entire analysis profile too, including data, filters, etc. and restore it for different datalogs later.

table interpolation (ex: port a VE or timing table from one ECM to another):

1. create a new 'table'
2. set a layout matching your original table
3. paste your data there
4. click layout again and enter your desired layout. it'll see you have data and ask what to do with it.

compare should be obvious, select two tables (not a datalog), but whats not obvious is the compare is dynamic, if you alter the source data the comparison is always up to date. its also totally interpolated so if you compare tables with different row/column values you can do linear interpolation there too.

graphing should be obvious too, right now 2d plot graphs only work for datalogs, 3d graphs for tables


it's really designed for people that would usually copy/paste their data too/from a spreadsheet, so it's the kind of thing you want your ordinary tuning tool open in another window and this just fills in any gaps

I have been thinking about something like this for a long time.
For linear layout a nice one will be-> set x,y-> initial;final points->step

And another very cool one, extrapolate a table with extra rows,colums.
You have 100,200,300,400 for a row->extrapolate and it adds extra rows with 120,140,160,180,200 and so on and fill the data in.

it does that!

the data that's 'off the edge' is the hardest. right now this tool lets you continue the slope or just set it null and you can fill manually.

i will add a spline interpolation method soon as well, for tables that we know are actually curved too, like a maf table or whatever.

[steveo]

but another thing is it can compare two tables with the same linear interp

so you can directly compare a table that is 100,200,300,400 with 120,140,160,180,200,300,350,380,400 or whatever

this stuff is really common when you tune subarus and stuff thats' why i needed it so badly for myself

awsome tool, comes handy when doing lots of tuning with different ECM/PCM but similar engine setups.
