adapter loom

Recommended Posts

ok made an adapter loom, got and issue on the BC5 4 plug loom you have B126/3 pressure sensor (power) & B126/4 pressure sensor(signal) and on the WRX ECU pin out it has only 1 out put B136/17 pressure sensor.

WHICH wire from the bc5 do I connect to the WRX pin???

Cheers Brian

Should be B126/4 pressure sensor signal.

But I think you will have to connect the other BC5 wire (B126/3 pressure sensor power), to a sensor power source. (5v source?).

TPS? its a 5v , but that means I have 2x 5v feeds going to the wrx tps pin, will that be a issue

Should be ok, looks like most ECU\'s run multiple sensors off one feed.

For the WRX ECU you have to only have one MAP Sensor wire, it must have a 5v Sensor Power Source Pin somewhere though?

What\'s the ECU code?

Edit: If there is only one TPS Pin, then that\'s the signal wire from the sensor to the ECU.

The TPS must have a power feed too?

      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
