yep
it would help to know what make/model engine is in the lift
but as edward said, timing is all in setting #1 piston on TDC and then setting the rest of the components on thier marks

this old style with distributor? or is it electronic ignition?
u say it has ecu so can we assume it has coil packs and no distributor? It would then have a reluctor wheel or something to count revolutons on the crank somewhere. And of course you still have to deal with valve timing etc.

without knowing the make of the engine we're all just spinning our perverbial wheels so to speak ;o)
