I have a 1996+ GM Vortec Marine engine in my 2001 Mastercraft X-Star. I know where the PCM is, it has only 2 plugs compared to the truck PCM's 4. Is it possible to tune it?

I very highly doubt it.
It doesn't have to be perfect, it just needs to be done in two weeks...

Related question, is it possible to tune LSx marine engines, say a 6,0 Mercruiser?

It really would depend on whatever operating system/vin is in the pcm currently. You surely can try but nothing is guaranteed.Originally Posted by tahoe

Thought most of the Mercruisers used the MEFI III or MEFI IV series controllers? If so, no dice.
Always Support Our Troops!
Would they even have a ODBII port?
Bumping an oldie. Has this changed? I dont know what ECU the new 5.7L and 6.2L Mercruisers use but I thought you guys might
The 6.2 has MEFI 5c
Bumping a very oldie.
What prevents the HP Tuners scanner from working with an MEFI ECU (specifically MEFI IV). The serial data output for the MEFI IV controller is on pin G of the connector. With a crossover connector you could get that data to pin 2 of the MVPI pretty easily and the ground pin A over to pin 10 of the MVPI. GM developed the MEFI controllers so I can't imagine the serial data stream is vastly different.
I know I could use TunerPro RT (which I have) but it is not nearly as user friendly as HP Tuners and I would prefer not to have to learn another software set unless absolutely necessary.
Just to be clear I would not be looking to write to the MEFI controller just scan/monitor.
The MEFI 5 is a 250kb CAN bus.
We plan to release reading/writing/licensing/scanning soon. We already have it working on my race car.
Stay tuned!

Keith, any updates on the mefi writing?
Reading/tuning/writing fully works. We just need to work out the licensing part. I expect we'll get to that in about 2-3 months.

Have you made any progress with the MEFI5 (&6)
Mefi 1-4 have their own cable mefi 5&6 requires a can cable adapter . Most use Diacom to read the ecm. Maybe hp will come out with something but for now I scan with tuner pro and write with mefi burn. You also have to have a password to unlock the ecm.
This is an old thread, but I am digging it up because Keith@hptuners said it was coming. Just wondering if I missed something. I am building a 383 for my boat and would rather not spend $600 for Mefi Burn if Hptuners can do it.
