Posted March 26, 200619 yr comment_161001 Hi,Im back I do like reducing my fuel consumption by 54%I have that dam engine runing ok now.I have found I need sum 30 degrees vac advance, with cold airStill few things to sort out yet (another 200 hours+++)Im looking for a computerized ign system. The mega squirt system only goes to 50 degrees BTDCIve emailed them a month ago and no response yet.I will need to have an basic offset of over 70 degrees BTDC (even higher)and the ability to fire as late as 14 degrees ATDC.?????? Does anybody know where I could find such a beast?????I will start porting the Z engine soon.My PC based system is ok, but its only for tunning an engine.I have still a bit more programming to doso that I can tweek the main timing curve in time it takes for 10 sparks to elapse at any rpm. sum stuff n results2.0 L Stocker early 80's setup in a wagon withPorting by me.....comp ratio 10.5:1 running ULP (will try BP 98 later.)43.7 MPG taking it easy @80 to 90 km/h and climbing 800 feet over 200 kmsUnconfirmed return trip ~50 MPG Thermal efficiency ~61.3% if I did the figures right !..
