Ref DIS: If I supply a rpm signal of over 400 rpm, the ecm will think the engine is running, no more/no less (true)?. With a missing cam sensor signal, there is a code set (I think), but will the rest of the data diacom gets, be accurate?. Meaning other then a code, and going to batch fire (if it was SEFI), is there something else I should look for??. Grumpy
