MS3 Pro Sequential Injection + Coil near plug conversion thread
Thanks. It should be better than that, there's so much capability to tune, I am not sure I will be able to take advantage of all of it. It's amazing when you look at this intake and it would be a 3000-8500 rpm range manifold with a carb and it should work fine here as it's really just dry flow now.
The detail part might be hard to show. Honestly the wiring for this is almost identical to installing this computer on an LSX engine for most of the connections, which the MS3 Pro website has great detail on. You have to remember that that engine has a 4/7 swap in the firing order. You also won't have a MAF or knock sensors. The finer points like the magnum distributor and the ford VR crank sensor I am using aren't too bad either. I can try to cover those as best I can. I will show the crank target and sensor bracket once I am sure they work. Not 100% sure at this point.
The intake, fuel rails, throttle body, fuel pump module, and regulator are straight out of a catalog, so nothing real big going on there.
The sensors on the holley throttle body are the basic 80's-early 90's GM ones, except the IAC stepper motor is wired Dodge style. I will be using the mid 90's 1-bar MAP sensor and also the coolant temperature sensor. Both are spec'd for a 1994 Oldsmobile Cutlass Supreme 3.1L. That's also a great source for all the connectors, you can either get them at the salvage yards or order them through rock auto. I actually bought an NOS engine wiring harness for a V6 GM for the connectors.
There are really only a few wires that need to be connected into the car. In my case, this is a bit different since my car already has an aftermarket harness. I also have a delco 12SI alternator which is probably different from most people's stuff too.
The computer is now mounted right above the fresh air box door on the passenger side.
With it there, I used 2 screws plus some HD velcro. Should be fine with that. The ECU is light. The glovebox should also fit no problem even with the wiring in place and you won't notice it once installed.
