Message	Please remember that. And with that spread, quite non linear. The best scenario for those figures would be to have -10 - + 20 This would place 5 LEDs at the bottom = -2 psi per LED, The 6 LED would be amboint = 0 psi of boost. This would be the calibration LED. Again remember (I keep saying this) LEDs -10 - 0 would be on all the time on the dash unless in a vacuum situation. So as vacuum increases LEDs go OUT not come on! Then 20 LEDs would be calibrated at 1 psi per LED. This way at least I can keep the +boost part Linear and accurate. It will involve a complete redesign to do it anyway. and quite a few extra components to go over 20 leds. I think my first will be 0 - 20 psi no vacuum as I no not have to re-design the gauge just change some values here and there for the 300z sensor. And I want to get something you folks can look at. There are some folks that want that configuration. We could always build a vacuum gauge seperately and put it some place else. Then I will do one off units as needed. Again if you are drilling your dash and installing the LEDS it makes my life easier. Also I do not have any vacuum testers, so it will be a calculation as opposed to a real test scenario, accuracy will be compomised on vacuum only a slight amount.
