Spreadsheet.
Anyone use the Spreadsheet that comes with the SERT Pro software? If so can you describe it's use and your experience?

That spreadsheet is for use by a person that is gathering data via wideband o2 sensors...
You have to plug in the Target AFR, as well as the observed AFR, and it generates a set of NEW VE's....
Useful if you are on a dyno and want to rapidly synch the VE's, vice doing the multiple runs....

Of what use is it to some one using the SEST?

It isn't really.... It is a carryover from prior to the Smarttune generation....
BTW, there IS an instruction tab on the bottom of the spreadsheet.. guess you missed that little tip.....

Ok, here is my thought. I've used smart tune to synch my ve tables, so in the spreadsheet......
I put 13.5 in the desired AFR
Copy my current corrected VE table to the spreadsheet
Copy my current AFR table to the Observed AFR
Do I now have a newly calculated VE table that will give me the desired AFR?
I am assuming (perhaps wrongly) that if my VE tables are correct, then my AFR tables should be very close to what would actually be observed.
I understand that this is not the intended use, but could this work or am I just crazy?

If you Smart Tuned correctly then you do not need the Spreadsheet. What you are proposing is that your current Smart Tune AFR Table is the same as live AFR data. This spreadsheet was designed so you set the entire AFR Table to 13.5, flash the bike, and run the bike this way to capture the live AFR data and compare this live data to 13.5 AFR Table. This spreadsheet would then make the adjustment/calculation to move your new VE table to 13.5 everywhere. When you are satisfied you have all the VE cells correlated to the AFR Table at 13.5 then you can adjust your AFR Table back to what you want and the Delphi system will adjust to the AFR Table value. The key thing here is that the VE tables are calibrated to a known AFR value. An example: If you are satisfied your VE tables are calibrated, then you can change the crusie area to 14.2 and the WOT line to 13.1 then the ECU will adjust the fuel in these areas. Once the VE table and AFR table is calibrated you can put the AFR Table where you want it and the ECU will adjust fuel to achieve that value. Hppefully this make sense.
