Crane Cams 168741 Cam for Gen VI stepped nose cam $220 shipped



MEFI 4 part #12569494 ECM with a 8.1 tune in it $200 shipped




Going with a larger cam and using a MEFI 4B

Is the MEFI 4 a stock cal and can you verify it is a good ECM - just asking

Did you convert from MEFI 3 - wondering then - do you have any wire harness or the adaption harness for the MEFI 4

Thanks

I have not ran the ECM i can ping it on the bench with MEFI Burn if you want or unlock it. I had a MEFI 3 on my 454 and bought a whole engine harness for a MEFI 4 8.1 and im going to spin my motor to 6800 its in a Vdrive boat. I have a reluctor wheel for a crank trigger set up to use the COP ignition i went to the 4B ecm to have tuning capabilities over 6000 rpm.

open to reasonable offers

Are the lobes all good on the cam? How many hours on it?

Hours unknown but the lobes look good on it text me at 5597907580 and I'll send you some pics

Was your MEFI 4 used for a Volvo Penta or Crusader 8.1 L / 496 CID app ? It would have been most likely for either one of those 2 engines is my thinking..

There is a paper tag tied to it that says 2004 Volvo 8.1. My bench harness from eficonnection should be here next week I can pull the calibration if needed or if this info is what you were looking for

I am very familiar with OEM stock Volvo Penta and all of their ECM's plus their fuel injection set ups. I would like to be able to pull their cals from E controls ECM but I already talked to the head engineer about that one. Man they are tight lipped about everything.

So can I ask at what level or experience you have with marine ECM's ? I believe your reply with be MEFI 1 thru 4b. Just a guess on my part and just asking.

If you find time to pull them that would be great - if not no problem. Is your MEFI 4 a recal or stock tune to your knowledge ? THANKS for your time.

Yeah I've got familiar with MEFI burn on my person boat and some ramjet engines. I have a 1968 vdrive Flatbottom with a single plane EFI manifold and a 4150 style throttle body on it.

I have a BDM frame and pull calibrations from Bosch ecms for Duramaxs. The ktag unit I have however has a bunch of marine options and the Motorola 555 ECM is supported. I don't have one to test with though I check on eBay frequently they are pricey.
