SUPRAGTE Forums Junkie Location: North Sydney Registered: May 2002	Dammit Tue, 28 May 2002 03:35 Just wrote a 4 page reply and the prick dissapears when i spell check it!!!!!! Well here's the short version. 1. I have a blanket ignition timing change that i do when i get a tank of fuel other than optimax. It simply take's ignition timing off accross the whole map. 2. I extract every available Kw from my engine by doing this. Much to your disbeleif Ed. 3. I'm saying that any detoantion is bad but i would definitely prefer to back off and adjust my timing rather than putting my foot down until i hear it. By then it's too late, some damage is done. They are called internal combustion engines not internal detonation machines. 4. Some dyno tuners tune by ear. At 6700rpm,14psi etc etc i would want the guy to use his ear to wait for detonation. Then turn around and say "mate there must have been something wrong with your engine". I've seen and heard it happen to others. Particularly with a 7mgt and standard head gasket i wont ever risk it. For Willwall98 the setup uses: - A VN V6 Commodore sensor bolted into the block. It made of a cermic plate that produces eletricity when it vibrates(detontion vibrations). -The input from the sensor goes to a VN V6 Commodore Memcal knock sensor board. -This normaly sends a CMOS/TTL output to the EMS of factory holden's and tells it to retard the timing. In this case we take the output and amplify it with a BC type transistor through some resistors and to an output LED. -The "black box" is powered from the cig lighter 12v. -It was pubished in zoom18 as an diy article but the schematic was way wrong. You cant get back issues that far anymore, i tried. If you want to make one, just msg or email me once u get the parts. $5 for the block mounted knock sensor,$60-$100 for the memcal and $20 for other electronic parts. Get the first two from wreckers.
