EFI conversion - VIN1049

I am not about to retype the whole thing, so here is a link to the thread on the other forum:

I'll be updating both sites with the same info each time I work on the car, in case people go to one but not the other.

Lots of good work done today:

Made a bracket and mounted the fuel pressure regulator. A little unnerving drilling into my car!
Mounted the vacuum advance solenoid, and run the vacuum lines and harness connector to it. Had to widen the mounting hole in, and used an M8 to bolt it to the manifold.
Mounted the idle speed motor and hooked up the air lines and harness connector
Mounted the relay board behind the rear parcel shelf
Mounted the ECU in the ECU area
Connected the ECU and relay board

Was going to drill & tap for the coolant temperature sensor, and begin wiring, but I ended up hanging out with my buddy Steve and driving his Viper for a few hours.

Lots of good stuff done today:

Ran live 12v bulkhead terminal on passenger side
Ran switched 12v from white bulkhead connector for frequency valve
Ran ground to metal panel in ECU area
Ran wire from FIdle terminal output to post-diode of idle circuit wire; for controlling ISM/vacuum solenoid
Ran wire from coil (-) for tach signal
Wired intake air temperature sensor

One thing I did to avoid future headaches was both solder and crimp any connectors I used to the wiring.

Looks great, Michael! I'm following this project with great anticipation.

Are you using the FV with EFI?

[opethmike]

No, the frequency valve has been completely removed from the car. I am just using its old 12v wire.

Swung by my mother's place (I keep the car there) on my way to the gym today. I took a few minutes, and played around with the mount for the throttle spool.

No reasonable way I'll be able to use the old one. The new one doesn't just drop right in, but I should be able to make it fit without too much hassle.

I find it interesting that so far its the small stuff like this that are the most aggravating/confusing/demanding parts of the project. I tell you what, if you want to learn how to improvise, convert your car to EFI!

Have your silicone plugs arrived yet?

With a little plate to mate the double holes to the single one on the top of the water pump, it'll fit fine. The main problem is of course that it rotates the other way. You need the throttle cable to enter from the rear/right meaning the cable needs to be longer. You will also need to bend up your throttle pedal *slightly* to give you full throw.

As custom work goes, it's pretty minor

Supposedly a box from McMaster showed up at my office today, but I'm not at work, so I'll have to get them tomorrow.

Cool, thanks Martin. Sounds like I just need to go buy a longer cable then.

[opethmike]

Martin, do you use just a longer inner cable, or do you use a longer outer cable as well? Do you have any pictures of the setup?


As far as progress goes, today:

I wired up the coolant temperature sensor
I wired up one bank of injectors
