infrared, just wondering about the WUR in your car. Yours is a '76 or '77, yes? For some reason its stuck in my head that the early turbo WURs behaved differently than the later cars. I seem to recall reading that the early turbo WURs respond to vacuum, while the later ones respond to pressure (and vac has no effect). No 1st hand experience here, but it might explain your AFR graphs vs. GAL's. Food for thought at least.
