Fuel Injected 200 NA

Post #1 by MustangMatt5 » Fri Oct 05, 2018 7:55 pm

Hello everyone, I am new here but have used the forum as a good resource in the past.
I have started on a project to fuel inject my 1968 Mustang.

Here is the setup so far:
1.Stock Points Distributor
2. Stock Coil

1. Holly Sniper 7psi Electric Fuel pump
2. Edelbrock Adjustable Universal EFI Fuel Sump running 58 PSI

I am running a Microsquirt V3 kit and I have built a custom intake and fuel rail.
Attached to my Intake manifold is a Ford 3.8l Throttle body.

At this time I have successfully wired the ECU and added my supporting mods to supply fuel and to provide a clean tach signal to MS.
I also have been successful in getting the car to run, however, not for long I usually only get about 30 seconds before she stalls.
I'm still learning the tuning process and how to manage the tables.
I was hoping others might have suggestions and experience in this process (specific to this engine) and a source for a close base map I can compare my tune against.

On the Sniper you have to lock out the centrifugal advance.
I would recommend to get rid of the points & go with a DS11 distributor.
Use an MSD-6al & a Blaster 2 or 3 coil if you want the best. The DS11 will also need to have the advance locked out.

Hi WSA111, Thanks. Yeah i plan to upgrade the Dizzy in the future ive looked at the DS11 and will keep that in mind. I also have been considering the pertonix. I'm keeping the points for the time being mostly because they work well and I'm actually using an MSD 8918 GMR signal pickup that gives me a clean signal to the MS ecu.

I need to get some better photo's but i added an image of my current setup.

Sorry for the delay in getting a response out. I got a little busy last week. Here is the image requested. You'll note i am using an Offy Tripower intake that came on my car when i purchased it about 9 years ago.

Update: i have successfully got the engine to run and idle. I found I was having an issue of losing Tach Sync once the engine switched from cranking to running. I am starting the task of learning how to tune the engine via software instead of using screwdrivers :)

I like it!
Curious why you are running an external map sensor?

The common plenum on the tripower is cool. I was brainstorming one day about a one barrel throttle body in the middle with two carbs plumbed off the return line. Your solution is more practical.
