Just managed a quick look at the car with the laptop plugged into the megajolt, It appears that I have done the whole run in limp home mode The megajolt is reading the vacuum/map sensor OK but is getting no rpm signal, hence no pulling power wouldn't go over 3000rpm. Limp home mode is if I remember correctly 10 degrees btdc, so basicaly no advance. This would explain the lack of power from the start!! That may also explain why a Vespa scooter 2 up was pulling away from us going up one of the Italian passes much to our amusement Nothing immediatly obvious with the wiring but I need to take a proper look when I get the time (suspect a broken signal wire between the megajolt and the edis unit or a duff edis unit). I also need to dig out my compression tester to see if number 5 cylinder has suffered any terminal damage as that did not appear to be firing since about 10 km before the overnight stop in Ulm. Every time we looked at the plugs after that there was no evidence of firing on number 5 as it was washed clean with petrol, we did try changing it out once or twice but it made no difference.
