MPI codes.

A while back I used a website which contained all the MPI computer codes. Now I cannot find it in my bookmarks, nor a search on this list. Anyone still have the link??

TIA!!!!!!!

Re: MPI codes.


I found this site, but looking at it, I don't see Jeep anywhere so it might not help:

Re: MPI codes.

Sorry, I guess I should have included more info. This is for the Hesco MPI kit, I belive it is a 94 YJ computer.

Thanks!!

Re: MPI codes (Again).

Scott,
I'm just curious here (a seeker of knowledge)........if the Howell is using the existing YJ computer........what different codes do you expect to get?......or does the Howell have it's own seperate cpu and it's own set of codes?

Re: MPI codes (Again).

I am sorry, I am not using the Howell, I am using the Mopar. The Mopar is a Modified 94 YJ Injection system.

Maybe I was not clear, I ment M.F.I.

Thx!!
