Sample screen shots of an EBL WBO2 tuning spreadsheet I've been working on. Copy paste the exported EBL .csv into a spreadsheet for "Closed Loop" tuning data. I'm trying to figure out the Knock Retard worksheet.
This is super cool. Any interest in sharing? I'm good with excel, just haven't tried anything like this before.
I think it would be worthwhile to create a sheet that can give you the average difference in observed AFR, or even a difference in BLMs, versus airflow over the course of a log. That has the potential to make tuning IAT values incredibly straightforward.
I'd also be interested in a sheet that could analyze acceleration enrichment, or at least compare average differences of delta TPS AE effects on the AFR.
I'm sure I could come up with more over time. Really digging your spreadsheet though! Let me know if you mind sharing!
Still interested Dave. I've been tuning with the EBL for a few years now, and this would be a great tool to work with. I checked out the the tool that ULTM8Z talked about, and I'm interested in that as well. The link for the ULTM8Z MAT tool wasn't working, so I haven't been able to download it yet. I would imagine the MCC works similar to the IAT calculations of the EBL. Not sure exactly how the bias term of EBL works with an inverse MAT/MCC; it couldn't be as easy as inverting it could it? I'm lacking in knowledge of that part of the fueling calc.
Thanks for that Dave!. I can see how the functions work, only averaging the values in between the RPM and KPA thresholds for each cell. The tedious part appears to be having to change the four thresholds in the formula of each cell. I might play with this a little, and try to come up with something useful. I'll post back here with any updates. Thanks again!

Interesting thought: Actual Spark Advance vs. Spark Table / Actual AFR vs. VE Learns .... something useful not provided by the WUD? Useful data that might or might not leave the competition looking at tail lights vs chasing tail lights.
Agreed, staying ahead of the competition is TEDIOUS!
Dave, that's a great idea. Leaving fueling constant, you could analyze how WOT AFR is affected by a change in timing. Visual display of a delta AFR for each of the RPM points among multiple advance curves would be interesting to see. Procedure would be pretty simple; make a few .bins with the only change being the advance at WOT, flash them, do a WOT pull, change to other bin, another pull, another WOT pull, another change...etc. Once done, chuck the three logs into a spreadsheet, Use fancy excel functions to grab relevant data from each log, and display the differences. Neat stuff!

Send me an e-mail... I'll e-mail you the file. Though, mine only works when using the S_AUJP suite of files... .bin, .adx, and .xdf
