Magnum and Wiring Swap

I have the Mopar M1 intake, a 53 mm throttle body, long tube headers, and the Hughes SER0814ALN-14 cam. My cam has a little less duration than yours, a little more lift, with the same 114° LSA. My car runs fine on the stock 1994 PCM. Your extra duration might be bleeding off a little more vacuum than the PCM can handle, but I have seen on the Magnum swap facebook group that other guys have run your same combo with success. Is your IAC nice and clean and moving freely?

Here's a link to the 94 service manual. It's basically the same as the 95, so probably not super helpful to you at this point: Dodge

I would like to find an M1 that isn't made of unobtainium. Guys want a fortune for them whenever they come up for sale. I read an intake comparison between a stock kegger, ported kegger, Hughes dual plane, and an M1. The M1 was the highest performer with the best flow numbers. The Hughes was marginally better than a ported kegger. My car and set up seems to run pretty good with the Hughes, so I'll leave it on for now.
The IAC is clean and I can hear the air bypass since I'm running an open element filter. I haven't actually put it in a test mode and cycled it to confirm.
Thanks for posting the link to the 1994 FSM. I'll go through it and see how different it is compared to the 1995. The 1995 makes more references to OBD II and shows relays for the low beams and parking lights, both things that were not in my harness.
