i hope so, its a lot of work. i envy garydoug writing his in visual basic - qt is a real ****. the real reason i wrote this is i'd never written anything with qt before, and it seemed like a nice starter project.

reporting back, I got it to compile and run. Haven't tested on the car yet. Had to change a few things in the source. I'll shoot you a PM so as to not clutter up the thread too much.

steveo_

thanks for the fix, brian. keep forgetting windows filenames aren't case sensitive, making things a bit more forgiving than on unix systems.

i have it building on my linux machine now too so i'll make sure it continues to build.

i've been informed the AFR works for standing tests, but loses its setting as you rev 'er out, and wont go as rich as i'd like. more study required.

Ok I did some testing tonight while trying to diagnose my car. The Cylinder Cut tool is not working correctly. Only some of the cylinders are being correctly canceled. It was obvious something wasn't right, I was canceling cylinder and watching the opposite bank o2 go lean. I was hopeful I had found my problem but after bringing home a labscope I confirmed the following:

Cyl Selected - Cylinder Actually Canceled

8 - 1
7 - 2
6 - 7
5 - 5
4 - 6
3 - 3
2 - 4
1 - 8

thanks very much! i'm testing most of these features on my bench ecm, so i'm not suprised they're backwards. i'll fix that in the next release.

steveo_

now open source, and posted on github, would appreciate putting bug requests there if you can, also anyone curious can browse the code and follow my progress!

Nice. I'll have to check it out.

another update posted. im not calling it a 'beta' anymore. most stuff works. cylinder drop test improved, notepad with snapshots added, bunch o other cool stuff.

This has been a lot of fun. I got it working sunday.

So what all do I need to play with this program? Also, can you actually flash with this?

steveo_

just an aldl cable that works. also need some libraries (they're on the page with the program).

flash read-write capability is all researched and mostly written, but i will not put it in the program until it's tested enough, because i don't trust it enough to not brick your ecm, and i'd feel bad costing someone a hundred bucks for a used ecm just because of a bug.

I'd like to see the ability to log wideband AFR through the 5v AC pressure sensor. TTS does this but it is an after thought on its part.

steveo_

i will add it in the next release, and it'll be in the output csv log, but analysis of the wideband data might take a lil bit for me to complete.

steveo_

one of the big features im working on is tuning-optimized graphing. the knock map is already super awesome.

steveo_

New 2.0 release of my tool!

Needs testing, please help me test 'er out

Download and more details here: fbodytech.com - eehack

Important new features:

- Autospark graph: a primitive timing skew modifier will adjust over a range of rpm/map. Helps construct new timing tables with less re-flashing. It's not super fast, but its awesome for tuning cruise ranges..
- Static analysis of logged data graphs BLM/INT against VE or MAF ranges, and plots knock events and their intensity on a grid
- Wideband-through-A/C input, display and logging with easy configuration (needs testing)
- New connect/disconnect and interface behavior increases stability
- Many new stability changes to aggressively maintain connection and get as much data as possible without drop-outs
- New raw data export (no import yet, but will help with analysis feature later....)

I messed around with it a bit today. Could you further explain the "cylinder balance analysis" a bit?

steveo_

a strong cylinder will cause a drop in RPM when it's disabled. a weak one will only cause a small change. a non-running cylinder will not drop RPM at all.

it locks the iac in position, forces fixed timing, and locks BLM updating.

it takes a reference reading of RPM with all cylinders running, then disables them all one by one for a short period of time.

it then displays the average of RPM drop below the reference rpm

steveo_

i should also mention that the wideband input is kinda working, but has some problems, so people with widebands should wait for next release.
