I've got about a bazillion hours into learning spreadsheets. Almost 13 hours into edits in this one recorded in the file.
Special Thanks to Dave W at Old School EFI for sharing his BLM spreadsheets, they are all included.
For evaluation only! I've tested till I'm blind and it all seems to work properly. Warning, spreadsheet on steroids! If it passes inspection I think it's worthy of GearHead-EFI.com name...
EDIT: New upload with protection issue on Injector Duty Cycle fixed.
Hmmm... Open Office opens all Excel stuff. It can also save as .xls so here it is.
1990 Chevy Suburban 5.7L Auto ECM 1227747 $42!
1998 Chevy Silverado 5.7L Vortec 0411 Swap to RoadRunner!

I protected everything so people would not change the cells that were not in White! There is no password, in Open Office just click Tools, Protect Document and Sheet to turn off protection. I assume Excell is similar?

The Excel message I posted states how to disable write protection. I was hoping to help others who might encounter the same write protection message.
I'm wondering where the formula for injector bias was sourced from? Some TBI definitions don't show an injector bias ($85, $OD, $OE, $E6, $31 $61, $62)? I think $42 usually has 454 injector bias @ .276 and 350 injector bias @ .375? I'm wondering if changing injector bias will affect injector flow?

I have excel too.
I tried plugging some numbers in but nothing changed. are these two not compatible in that way? (preface: imanidiot)
....and you just posted it.... LOL!
Thankyou for that sheet Mark.
I've only tuned my truck.......but I do have a couple people interested in me helping their trucks out and that spreadsheet will be most helpful!
It's really cool to have a community like this one. :)
Damn! I'm sorry to here that. I feel like I know the guy after reading all the work he has done here for us. Of course I guess it is nice to know his legacy lives on!!!
The spreadsheet in post #18 is an Open Office .ods file: https://www.openoffice.org/ if you want to download and use freeware Open Office.
Post # 20 has a Microsoft Excel .xls file if you have Excel. I've also re-attached the file from Post #20, see below. I just tried using the attached .xls, seems to be working for me.
Please update me with your progress.
