ok so i have got everything going but now i have a whine from the alternator i believe and goes up and own in pitch and in time with the engines rpm from what i read its cause by having the rca leads and the powere wire being close together but ive wired specifically so this wouldnt happen

any ideas on how to fix this?

simple solution: get a ground loop isolator from jaycar for less than $20

other than that check all your earths, headunit/amp ( even the battery earth for good measure) , did you scratch some paint off in the boot to expose metal to mount the earth too?

Jason (Spark_38) from the welly crew is pretty knowledgeable on car audio installs might be worth giving him a PM

my headunit has the same issue ( sony Xplod) but cant be arsed to fix it until i have a new headunit, then everything is getting replaced @ the same time, have started buying cables etc, started with some triple shielded RCA's

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
