if your looking for one of the "higher end" systems i would check into the ProM stuff. youve got an excellent source for info here with Michael Plummer.
Thanks for recommending me as a source of information on the Pro-M system. Now if I could get paid for all the recommendations I do on this system, I might have a nice nest egg for my retirement.
AJs92Fox's questions and my answers
Q) I'm looking for a system that is best suitable for street application.
A) I believe any Engine Management System (EMS) will work on the street. How hard or easy is the learning curve and how hard is it to get a car up and running properly will depend on your tuning knowledge. Just or the record, I had none when I installed my Pro-M EFI system.
Q) What wiring do these systems come with, for example injector wiring etc?
A) The Pro-M EFI comes with a complete Engine Management harness to run your car and yes, your injector harness is a part of your Engine Management harness.
Q) What extra pieces should I purchase as well?
A) Extra pieces...None. But you have options like Innovate widebands, and a coil on plug option.
Q) If I gut all wiring from the computer, is this new system going to replace all of that?
A) Slow down before you start ripping things out. If you purchase a Pro-M system, you will get the harness that goes to your new OBDII Spanish Oak processor and injector harness. This is everything you'll need to run your vehicle.
Q) I plan on using all computer wiring from 92 on a 87 T-top i am building, so I don't want to get rid of any thing I might need later.
A) This is why Pro-M custom builds a harness just for your setup. Think of it as a stk. harness made especially for you by Ford.
Q) I've never done this before, so I'm trying to do my research before I start talking to dealers.
A) Neither did I and you can read about my experience and or watch the videos it may be easier.
In closing, The Pro-M EFI system would be a great choice due to the excellent drivability it provides, and it comes with a complete replacement EFI harness. It is also very simple to use, which will be very important, especially to someone who has never done this before. Do a search on Pro-M EFI and you'll hear the same comments among it's users, great drivability, ease to get running, quality product, easy to understand, etc. Or checkout Pro-M EFI on Youtube.
