ther was a thread going around a while back, i can't find it now, but someone was asking about setting their ignition timing and found that it ran much better around 8* BTDC rather than the recommend 6* and something just struck me. when you are setting your engine timing on most models of cars you have disconnect the vacuum advance from the distributor and plug the hose with a screw or something. you will notice the engine RPM change and this is where you should be setting your initial engine ignition timing. on my 95 toyota truck EFI and my 91 daihatsu charade EFI you had to open up the relay box in the engine compartment and put a jumper wire across two terminals in what look an empty spot for a relay. this would change the engine rpm to set the initial engine ignition timing. the jumper wire was not a "trick" is was how the factory manuals explained to do it. when you finish setting the timing and connect the vacuum hose (or remove the jumper) make sure your distributor is advancing. rev the engine and make sure that mark moves, you should usually see (and this is a vague estimate) a minimum of 20* advance from idle to high rpm.
