Default Help on Road Dyno EBF Spreadsheet

Hello all....just downloaded this spreadsheet. I know I have to give the time (s), RPM and boost. Anything else I am missing? Also I do not know what are the a=? thru g=? constants. How can I get those values. I did plot a dyno from a previous run and comes out screwy (gave me 350whp when I only have a reflash and a CBE).

Here are my logs:
Sd RPM BST SPD
0 3904 -7.11 24
260 2528 -6.09 24
520 2599 0 24
781 2665 2.76 25
1031 2802 5.51 26
1291 2944 9 26
1542 3103 12.62 29
1792 3316 13.64 29
2052 3579 13.64 31
2313 3769 13.78 31
2573 4008 13.93 35
2824 4206 13.64 35
3084 4423 13.35 39
3334 4693 13.06 39
3595 4888 12.04 43
3845 5110 11.17 47
4105 5348 10.74 47
4366 5554 10.16 51
4626 5733 9.87 51
4877 5921 9.72 55
5137 6049 9.29 55
5397 6276 8.85 58
5658 6388 -10.59 58
5908 6180 -11.03 62
6168 5714 -5.22 62
6419 4140 4.79 63
6679 4664 12.33 65
6940 4574 14.22 65
7200 4784 13.06 66
7460 4847 12.48 66



Thanks

Make sure you are using the correct weight and gear ratio.

Hey, since I made that spreadsheet, I can certainly help you out. Fix the link to your datalog and then I'll update the spreadsheet correctly with your results and repost it.
