Bought a wrx for my self and apparently the chipped ecu was bypassed was even dyno tuned for it, not sure why he would do that. I know it sounds very blunt but how would I go about to restore what it was before?

in the early "chipable " ecus there is a wire or a jumper that you connect or cut to tell it to read from the stock rom or the additional rom that has been installed /tuned

have a bit of a google or wait for someone with more info

well im assuming this is what your comment refers to . it seems fitting if that is what you got told and are un familiar with it

From memory there\'s a resistor on the board that gets cut for it to read from the chip. To bypass the chip, they just re-solder the resistor. Might be easily recognisable if its been re-joined. And in that case, just cut one leg off the resistor again.

Sweet as! Those things are the greatest invention since the wheel itself.

Best bit about them is because they smell so good, you just want to keep using it.

thank you again ! took out the ecu and there it was, a brown resistor with solder on it. Cut it off and now feels its pushing out alot more boost.

about the caramel wheel, I had my garage open while using it and half the time people walking pass stared at me weird as I was just sitting there sniffing it ;D

      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
