LONG Thu, 22 January 2004 03:52 ok... re the flat spot: it ISNT the cam timing it ISNT the base ign timing it ISNT the knock sensor i mucked around with everything this morning. set everything back to stock. zero difference. sure the character of the engine changed generally, but the big mofo flat spot remained as-is. no amount of changes to base ign timing made sfa difference. changes in cam timing ditto. i dont usually have any audible evidence of pinging as it is, so it was impossible to tell if id done anything by dropping back the base timing in that regard... ...so i just set the timing back to a point where it wouldnt ping audibly trying to go up a hill @ 30kmh in 4th gear, which turned out to be 16-17deg BTDC. exactly what this means, in not entirely sure. when you brigde the diag terminals to set the timing, how much advance is the engine ecu givin? 10 deg? does that maen ive just dialled in a further 7deg on top of that? i honestly cant tell the difference b/w having the terminals bridged, or open, they both looks the same under the timing light. interestingly enough, either bridged or unbridged, give the throttle a quick squeeze, and the timing swings around to almost 40-45deg BTDC!! yikes! anyway, nothing i did removed the flat spot whatsoever. atleast i can be confident now that the ign timing is ok. i think ill install some water injection over the next few weeks and see what that does. if anything itll let me wind the advance up more amd lean out the mixtures a little more, and i can be sure she aint pinging then! cheers ed [Report message to a moderator]
