Title: Fuel trims tool
Post by: shnazzle on November 2, 2019, 10:10
If anybody is interested, made a little Excel spreadsheet that allows you to import Torque data and display average fuel trims from tons of logs.

I've included an example log file, so just make sure your log file is the same structure.
Basically it's just RPM, LTFT1, LTFT2, MAF and THROTTLE

Questions, let me know

Instructions are quite simple.
A) make sure logs are in the same format as the example.
B) put logs you want to load into one directory (recommend no more than about 20-30 depending on computer). Try 10 and go from there. Obviously the more logs, the better the coverage. But, keep in mind that weather has an impact. So, try to stick to a few months max.
C) load up the excel and make sure to enable macros
D) press Load Data and choose the directory where your logs are held
E) top two graphs are bank 1 and Bank 2, 3rd graph is the difference,and 4th is maximum MAF values.
F) you can press Reload to redraw the charts based on the same data.

Hi Pat,

Is there an idiots guide to Torque pro anywhere on the forum?

I really struggle to make sense of it.

@shnazzle
C) load up the excel and make sure to enable macros
Keep bumping into a warning about security too high, so dropped to lowest or need signing by author.

Yeah you just have to kind of do all of the "I accept that this guy may be hacking into my computer and destroy my life"

Just noticed that for some reason sound doesn't kick in until 34 seconds in. But luckily you don't miss anything, it's just me talking crap
