Can anybody tell what PROM the W41 should have? The ECM that I got when I bought the W41 engine from a friend has an ANMS PROM. I looked at the volumetric efficiency table and the values are significantly less than those in an AUKY PROM that I know is from a high output Quad 4. Me thinks that the ANMS PROM is for a low output Quad 4.
