In dire need of a computer for a 2000, HP 500 EFI, mine has gone south and will not hold a program. Thanks much.

Anybody got a computer laying around??

What Do You Need A Mefi 4 Or Mefi 5 I Have Both And They Are Blank. Let Me Know.

The original would have been a MEFI3. A MEFI4 ECM could be made to work with the proper calibration and repinning the wire harness.

By y Boy, where the heck did you get a MEFI5 ECM??

Dave

Don't Really Remember How I Came Across Them But I Think I Have 4 Mefi5's And 2 Mefi4's

Which one would have come from the factory on a 2000, HP 500 EFI. Really don't want to change the wireing harness.

MEFI3 BUT YOU CAN DOUBLE CHECK ON THE BOTTOM OF YOURS IT WILL TELL YOU.

What are they going for? I have 2 MEFI 3s

Thanks, don't know the going price for the computers but you can email me and we can go from there. [email protected], thanks much
