I recently acquired a W41 Quad 4 and it came with a PCM. The PROM in that PCM is an ANMS. I have another PCM that is from a regular Quad 4 HO. That Prom is AUKY. I did a comparison between the two PROMs and the volumetric efficiency values for the AUKY PROM are significantly higher than the ANMS PROM. I'm thinking the that ANMS PROM is for a low output Quad 4 and I got the wrong PCM withthe W41 deal. Anybody have a W41 and can check the PROM brodcast code.
