Crazy Al Posted July 14, 2005 Report Share Posted July 14, 2005 Ok you tuning guys I have a question for you. My father has a Merc Cruiser 454 Mag in his 27' Checkmate. Last year we put an intercooled Vortech supercharger on it and sent the PCM to Vortech to be reprogrammed. We adjusted the fuel pressure according to thier specs, but the boat seems to be running a little rich. Can this be tuned with EFILive or Hypertuners? I'm not sure how I'd plug into it or if a harness would need to be made. How hard do you guys think it would be to adjust the air/fuel levels for a beginner like myself. If I can get him to buy something maybe I'll go in half with him and use it on my truck too. Thanks. Alan P.S. It does 80 and when I ride in it I look like Quote Link to comment Share on other sites More sharing options...
TurbochargedBerserker Posted July 14, 2005 Report Share Posted July 14, 2005 It depends what PCM is in the boat (e.g. if its an automotive PCM, what year/model its from and whether EFI or HPT support that year and model). Quote Link to comment Share on other sites More sharing options...
vtecths Posted July 14, 2005 Report Share Posted July 14, 2005 Ben over at Arizona Speed and Marine would be a great resource for your boat related questions. They deal with high-end boats all day long. He is very knowledgable regarding pcm tuning for the boats. Their number is 480-753-0208.

Crazy Al Posted July 14, 2005 Author Report Share Posted July 14, 2005 My father actually bought a kit from AZ Speed and Marine the year before that included a new flame arrestor, MSD ignition and a reprogrammed PCM. Didn't notice much differance, but I'm trying to prevent sending the PCM out multiple times to be adjusted. Quote Link to comment Share on other sites More sharing options...
zippy Posted July 14, 2005 Report Share Posted July 14, 2005 i would check with the guy from mondax. they make the tunercat tuning system and i'd guess that would be your best way to make that work. tuning yourself is your best bet of course of making this work.
