Stroker Tuning?

[dingo151]

Waht are you guys using to measure your Air/fuel ratio on your strokers? Just wondering if there's good or bad ways to go about it? I've got a OBD 1 system.


Thanks

Mine is a 96. I have a "test" pipe w/ 2 bungs for o2 sensors(96+ have an aftercat sensor) between the downpipe and muffler instead of the cat(that melted when the coil was going bad and didn't spark for a few revs and when it did. . .). You could drill a hole in the pipe in front of the cat(on the side or top of the pipe so that the sensor doesn't sit in water/condensation; also, you want to be near the front to get the most accurate readings) and weld a bung in, or you could purchase a wide-band o2 sensor that also has a parallel narrow band output, remove your old stock sensor, put this in its place, and wire this one to the old one's output. I like innovate motorsport products and would recommend an lc-1 for obd1 and an lm-2 for obd2(I have this).
