any one know of a workshop in melbourne who can PROPERLY tune a 4age 20v bt with adjustaable cam pulleys,

i have a iiregular miss at about 3000 rpm ,i think the timing is out .

tune or repair? which ecu?

ae111 standard ecu

you can't tune a stock ecu apart from adjusting the timing, and that won't cause a miss. I suggest checking your capacitors

I can't imagine adjustable cam gears on a standard ecu would be entirely ideal? (assuming they have been adjusted from their stock position)

it's not ideal no but can work, apparently according to some of the South Africans 20v engines like to have their exhuast cam alterneted by 2 degrees
