Have built my megajolt light v3 and all is ok apart from the fact that with the engine switched off the rev info still shows 400 rpm. Have isolated the megajolt and in fact connected it to a 6volt battery with no other connections apart from the rs232 to my laptop. The rev counter still reads 400rpm. I can load a flash config and save it ok and the map sensor operates ok. But what is the problem have checked all kit build and all seems ok.
Can you help as with a +400 rpm it will advance incorrectly
incorrect rev info
