csv log analyzer (EE and maybe others)

**steveo** · 06-15-2015

i do a lot of my tuning using a homebrew analyzer for log files in linux.

due to a few requests, i've ported it to work with dos/windows so other people can try it out.

would you like to test it out? let me know how it works!

i've set it up to work out-of-the-box with Scan9495 log files, but can also be configured to work with tunerpro (configs/instructions included).

i think datamaster logs can be used by importing them with scan9495 and saving them. i haven't tried yet.

here's what it gives you;

BLM per-cell analyzer, useful for figuring out how to reallocate cell boundaries, or to figure out ranges of AFR within a cell.

Lots of new things to look at.
Downloading scan9495 and installing tonight. Looks like an easy program to get to know. And since your log analyzer is set up for these logs without conversion, this is the way to go for me. I'll do some data logging and see what I can get figured out.

I hope one of the cables I have is compatible with scan9495. I have an old Andrew Mattei serial to ALDL and one with Craig Moates APU1.

I have never reallocated cell boundaries, this should help a lot.

All these functions are amazing, and can see how it will dial in my tune.

The knock cell function should be interesting in my set up. I basically have my knock system disabled for now. I have false knock issues ( solid urethane mounts, large link single row timing chain, valve train noise, Long tubes, etc.. ) that drove my knock sensor nuts, wrecking havoc on timing tables.

This should be fun!

Thank you for your hard work!!

I hope one of the cables I have is compatible with scan9495

it should 'just work' with pretty much any serial cable. it doesn't do anything that tunerpro can't do with a bit of work, but it's a nice program just because it's LT1 specific, it was basically made to replace the old gm TECH handhelds.

I have never reallocated cell boundaries, this should help a lot.

it's really common to see an entire row or column of the blm table go pratically unused; definitely a waste. but do remember that you want more cell boundaries in areas with more varied fueling, so don't try to split the table up across the entire rpm range.. lower RPM is generally where fueling is all over the place.

Having some trouble getting scan9495 to load without errors. Tried on both my laptops. Thought it may have been because I loaded the program before plugging into the aldl. Tried several ways. I'll try a fresh download, and reinstall. Wish there were a way to check integrity of a download, like an md5 comparison. If all else fails, I will do the data logging in TunerPro Rt, or datamaster.
