ignition timing issue....

[WHITE R32]

hey guys i was wondering if there is any way to retard the ignition timing at like full load up in the revs and boost at like 1.5 bar cause i am having pinging under heavy load when it hooks up....its still a std base ecu (mines ecu) .... any help ideas would be appretiated... cheers Jon its a manual r32 gtst by the way...:uh-huh:

i am also installing the malipassi reg next week i hope which should help with more fuel delivery ....

im having a similar problem with mine. Buts its not pinging, at least it doesnt sound like pinging from the engine its just u can hear a crackling effect under full accelaration in 2nd gear mainly and 3rd abit less. Mines a r33 gtst and has a boost controller. Just got the car on tuesday and dont want to do any damage to the motor. I tried turning the boost down afew notches but it still does it. I bought some iridium plugs for it but am yet to put them in. Hopefully that will help. Any clues?? guess u cant really help to u actually know what the noise it?

malpassi is a cheap mans way to overcome that little extra bit of fuel under wot , though it does work well.

a little way i thought of reducing timing was to make an actuator retarded dizzy , similar to ur wastegate , it has an actuator which when boost rises it slightly pulls the dizzy back in turn retarding timing , it would take a lot of work to make it but i think it would work.

i have moved the cas to retard the base timing a little and i have also reconfigured my rocker cover to air intake pipe whick i think was getting tooo much straight oil into the cooler and intake hence reducing the ron of the fuel causing detination and also reducing cooling capabilities of the cooler and causing some smoke... will see if this works...

good stuff

most ppl neglect to do it , but even the smallest blow by , being re-entered into the intake system , dramatically reduces the octane of the air/fuel mixtures , and increses the risk of misfires to detonation. etc
