Well I have an update and a question. I tried to start the car today and was not successful, well sort of! With the Saw wire connected nothing
Was happening bar a few backfires, but with Saw disconnected and running in Edis limp mode it fired straight away and ran lovely!
So I can deduce I am missing something inside megasquirt. I have changed the spark map for one a little more specific for the MG, I have set MS for 4 cylinders. As said I have the trigger wheel set 90 degrees behind the missing tooth. So can anyone suggest any settings I may have missed? I've read some of the megamanual but not found anything apart from discussion on trigger angles, however these settings cannot be changed in my MS for some reason?
