Hi there guys/girls, was wondering does anyone have any excel worksheet examples for calculating the ETC scaler area..Tuning a E38 PCM L98 with a 102mm Throttle body , ive noticed some numbers from 5,636.0000 to 7,380.0000 so just need to calculate the area using that style throttle body cheers Bret@ultimatelsxtuning
If it's a Nick Williams 102 use something more like 7900 to 8100. They flow better than the Fast 102's for whatever reason
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

cheers Fellas ...yeah only use NW throttle bodies
So with 90mm TB it should be set to 6362
What effect does have the wrong setting, mine is set to 5,636 and am running a 90mm TB

7.190 is what I have plugged in. If it's not what it should be, I'm still leaving it where it is, because it works fine.
This thread has some good discussion points, and methods to calculate for a larger TB. http://www.hptuners.com/forum/showth...TC-area-scalar
When arguing with an idiot, make sure he isn't doing the same thing....
