where to weld the wideband sensor?
#4
Ended up welding it on the horizontal section at the beginning of the B-pipe. The HKS kit's AFR is very boring. At idle, when the car is completely warmed up or during red light, the AFR is around 14.7-15.2. full/sudden throttle the number drops from anywhere around 12.6-13.5. i dunno if the numbers make any sense. i guess it's a pretty timid carb legal kit.
got my AEM F/IC in TODAY. waiting for boomslang harness.

Yep, that sounds about like the AFR's you'd see in a CARB legal kit.
You wanna be at or around 14.7-15.0 in vacuum, or leaner if you wanna try a lean-burn cruise. Near 0 vac and in boost you ideally want to see your AFR smoothly decend into the mid or low 12s. Anything at or above 13 in boost makes me nervous, personally, but with a good tune I guess it's a possibility. The general rule is you CAN hurt things by going just a touch too lean, but it's pretty tough to do that by going too rich.
