Im running the 3 pin hall cam sensors at the rear of the head. Do these need to be shielded? Ive been reading that hall arent susceptible to noise like the standard issue 2 pin sensors. Made a new loom to test wiring and seems to work fine unshielded.

Hall effect can be thought of as an almost-digital signal as it's a square wave (and is probably interpreted digitally anyway)

So it will be much less susceptible to noise because 5.1v or 4.9v still looks more or less the same as 5v (or whatever the signal reference voltage is) and is interpreted the same.

Likewise 0.1v or whatever you get from noise is still going to be considered "0" or "off" or "low" or whatever parlance the ECU prefers.

Short answer not required as long as the noise is less than a couple of volts... and if it is, you've got other problems!!

Probably quite a nice signal to put a scope on if you're learning how to use one - you'll get a nice relatively stationary square wave on screen once you've got the scope dialled and you can watch it accelerate when you rev the motor :)

The cam sensors being where they are get coated in oil. Guess that doesnt effect the signal? Same setup as v7 but hall. Will scope them sometime prob this weekend theyre a 3 tooth trigger at 90deg so should be easy to see like you say.

Going to reloom cop from ecu to pack and see if that fixes it too. Had endless issues with the wiring harness that jason liefting made.

      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
