I think I've answered my own questions about the pressure. 39-40psi will be ok, EBL's BPC tables will handle it. Base pressure on the 20-60# spring needs to be set at 39-40psi with the vacuum nipple open to air. Then connect it and let vacuum handle the pressure drop at idle, with corresponding BPC vs. VAC table values. I expect a touch over 15" Hg at commanded idle speeds with IAC vs. temp at normal operating temps. Next question is why am I missing the BST-BPC vs Boost for a 1-bar MAP?? I see 4 tables each for 2-bar and 3-bar but none for 1-bar. I looked in the option words and as expected none of the 2 or 3-bar words are set, and apparently I didn't miss turning on the default of 1-bar MAP. So, if using a 1-bar MAP, just don't worry about the BST-BPC vs Boost? I think this is pretty much the last thing for the base starter tune. Again, any feedback or criticism of anything I've posted so far with any of this is appreciated.
