[QUOTE="radman, post: 16210, member: 167"] MAP=manifold absolute pressure. You'll see it attached to the throttle rail with a vacumn line plugged into the bottom of it. Senses manifold pressure and regulates the injector pulse width accordingly. There is also a Intake air pressure sensor in the air cleaner assembly, which is responsible for generating a signal based on intake air volume, hence temperature sensitive. Strangely enough, my experience with Frank has been just the opposite of yours, when hot out, Franks performance suffers. However, the heat here is accompanied by high humidity, which displaces air and oxygen in volume, and may throw the whole mess off. [/QUOTE]
