Where might I find this item in a A9L GUFB?

'Throttle Body Air Flow' (aka ITHBMA)

Well,
Thanks Dex.
But I searched everywhere and I don't see it.
What catagory is it in?

I'm not at home at the moment so this is from memory, I think it's under the 'hardware' category. If you use TunerPro's search function you'll be able to find it straight away.

It's under the Hardware group
Isn't that number suppose to be the actual size of the TB.
Like 75mm or 55mm?
I have it set to 75mm, since that's the size of the new one

It's the air mass flow through the throttle body when the butterfly is closed against the idle stop screw and the ISC dutycycle is 0%. This value is used by the eec to determine the ISC dutycycle required to meet the calculated desired idle air flow.
