I used the BLM Locker and switched the Performance/Normal Shift Points on the Cadillac towing bin file. How do I add the 20% fuel to the WOT AFR table? Is there a way to do it on TP?

Well mine needed 20% and checked with Wide Band O2 sensor came out to 12.8 to 1 AFR.
But if you do the math included in the TunerPro XDF file it is closer to 15%.
It is in tables "PE % Change To Fuel/Air Ratio Vs. RPM at WOT "
Ratio Vs. Coolant Temperature are summed to arrive at the Power Enrichment Fuel/Air Ratio.
The resulting air / fuel ratio can be calculated as follows:
PE AFR = 14.7 / (1 + %Change vs Cool/100 + %Change vs RPM/100)
For the selected RPM, suppose the percent change to Fuel/Air Ratio from the RPM table is = - 5.1 and the percent change to Fuel/Air Ratio from the COOLANT table at the selected coolant temperature is = 22.7, then the approximate Power Enrichment AFR would be:
14.7 / (1 -0.051+.227) = 12.5:1 AFR
Basically, for every 1% that you adjust the %change vs RPM table, the A/F ratio changes by 0.147.

Where do you find these formulas on TP? I went to the View/Edit Parameter XDF info(F2), then to conversions, is it that conversion to use? Can I put the cells value in as 'X' and it will sum it up or is that not how TP works?
Edit: If that is not how to do it would it be with the Function, Value, and Execute buttons on the table itself? IF that's the case would it be that with a %change of 0.78 multiplied(Function) by .2 (20% Value) then hit execute --> 0.78*0.2= 0.156
Take that 0.156 (rounded up to make 0.16) and add it to 0.78 to equal 0.94, is 0.94 the new number for that cell? 0.78+0.16=0.94
Is there a way to add the 20% to the whole table or do you have to do it for each cell?

On mine I left the 800 RPM alone and started at 1200 to 5600 RPM and left higher alone as I do not need to rev higher and don't want to rev higher.
Multiply, for 20% use value times 1.20. For 18% multiply by 1.18.

How did you get those values?.. 1.20 and 1.18
When I multiply the cell value by 1.18 and hit execute I get one number but if I do it on the calculator I get another.. why is that? Which one is right?

I don't know? If I multiply anything in TP by 1.20 or do the same in calculator it comes out the same... got to use your "." in the right place.

Ok, got a tuning question. I just tried programming my pcm for the first time. I tried 3 different bins and every time turned out to be the same.. The car will crank and start but dies right away. I am able to program the original bin back on the pcm with no problems but can't use any others. I am able to read the files though. I am using the WinFlash software.
I am using a 94 SS adx and xdf file. I tried a Cadillac, stock Impala, and a Cadillac tune with a couple things changed.
What am I doing wrong?

No idea how that happened... I didn't change any settings.

Sounds like your not saving the bin after changes? After you make any changes in TunerPro you need to save the bin file so the checksum updates. Close TunerPro, open Winflash and reflash PCM. Need fully charged battery on car and laptop, key on, engine off, everything off, no interuptions!
Then I could not read it when using the light forum color. Always use default or automatic and it will be correct for Dark or Light...
