200kSpecB

Haven't been on here in a long time...

Took the spec B out for the first time in months, haven't driven it much since I got the S4.

I gotta say the spec B might be more fun to drive, you can really feel the weight difference between the two.

It definitely cant compete in a straight line though lol

I was actually thinking of the wrong thing, I was thinking of people logging AFR through the TGV but from this looks like oil pressure is also possible... https://legacygt.com/forums/showthread.php/btssm-afr-oil-temp-oil-pressure-rear-o2-tgv-left-275477.html

and if I remember correctly this is the plug you're looking for

Yup thats the oil pressure sensor but the OEM unit is more of an on/off switch. You have two options: you can either unthread that guy or locate the other plug closer to the back of the engine and install the new sensor there (most people like this option the most).

As for checking the oil pressure, again you have two options: the easiest option is to run an aftermarket gauge and sender and place the gauge somewhere on your dash, OR the complicated way is you can delete your TGVs and do some stuff that I can't remember and then create a custom field in BTSSM to read the TGVs from the ECU but it actually reads oil pressure.
