how do you effectively dogfight a spit with a 109 with equal E

[SEE]

Not sure about that Ze-Jamz (in my experience) - pretty evenly matched at very high alts as long as the Spit jockey doesn't try to follow a BF down but extend maintaining (or gaining if possible) altitude/speed and, most important of all, - visual contact. The latter contibutes equally to the outcome rather than any weaknesses/advantages in FM.

Standard procedure for me would be to pull up and face another direction so I can keep a good look on him, if he turns into me I radio for a quick drag & bag action, if not I start maneuvering towards him and drop in on his low 6 oclock from height, and only fire when either he notices me or his whole plane fills my windscreen.
