3209, Basic MS setup
Posted by python6586, May-29-07 04:54 AM
right now i am running 15psi on 440's with the sfmu and i really dont like how the sfmu so roughly tunes. i did search but cant find answer to exactly what i need. my basic question is this. If i get the MS board from RS autosport what else will i need to control fuel only. Do i just need to wire the board in install the software set my constant fp with the sfmu and tune? or do i need more sensors and adapters and relays and such?

your gonna need a few sensors...
coolant (CLT)
Intake air temp (MS refers to as MAT)
also going to need some kind of harness to install it and hook it up to your car. Look on the ms forums and use a search engine to find the megamanual. I installed mine by using the search button on this forum. The info is there, just not always easy to find.

+1 on the search and Megamanual.com. You don't need to add any relays, just use the existing ones. Let the factory relay power the fuel injectors and let the MS ground fire them. Use the fuel pump wire going to the factory ECU. Place the IAT (MAT) sensor in the intake tube, seems to help with heat soak. The install is pretty straight foreward; make sure you have a good ground and don't bolt the MS case directly to the chassis (spikes).

Thats what I did. I meant to say that your going to need the DB37 connector to the MS with some wire. RSAutosport and a number of other places offer a preterminated harness that plugs directly into the Ms with about 12' of wire to run where ever you want. The sensors with pigtails are also available at these places.

plan it all out ahead of time, take meaurements, check fit up, and take your time and you should be very pleased with MS. I think the worst part of my install was the numerous trips to Radioshack...they know me by name now...
