DIY TBI Fuel Injection for the AMC 258

I'm worked out the details of putting GM TBI(Throttle Body Injection) Fuel Injection on the AMC 258 in my CJ7. I never completed this modification, so I can't make any reccomindations. I built an eprom programmer, converted a distributor and had all the parts. When my daughter let us know she was coming, I sold it.
This is here for informational purposes. I'm not responsible for your actions. Have fun!

Why consider doing this mod when there's a nice carberator there right now? EFI gives you tremendous control over your engine. Think about how many times you've driven a newer car in cold weather. It started right up. You can make your jeep do that for you without pulling on that choke knob. The upgrade gives you a better ignition system, better fuel efficiency, better cold weather performance... It just gets better. The system really isn't that complex. The GM TBI is a very simple setup, and most of the parts can be had quite readily from the junk yard. Howell Engine Development will sell you all this stuff for around $1200. I'm getting all my parts from the junk yard for under $100, except the fuel pump. A new fuel pump runs about $75 at autozone.

Tools you need:

Eprom Programmer
Eprom Eraser
Spare Eproms
Multitester
ALDL cable
Computer
Usual Automotive tools

Parts you need

Complete TBI system from a chevy astro van or similar:
Wiring Harness
TBI to intake manifold adapter. TBI unit
ECM(Engine Control Module)
MAP(Manifold Atmospheric Pressure) sensor
CTS(Coolant Temperature Sensor)
Oxygen Sensor(You'll probably want a 3 wire heated style)
GM ignition module
External High Pressure Fuel Pump
optional:
VSS(Vehicle Speed Sensor) from an 80s Jeep Grand Wagoneer

Master E2182 Fuel pump - $66.99 from autozone.

What to do with all the stuff

The short version:
collect all the parts. Simplify the wiring harness to include the connectors for all the sensors you are using, connect to the correct ignition module you're using, and the ALDL interface. Now you'll need to modify your distributor to use the GM ignition module and reinstall it if you took it off. Next install the TBI to Manifold Adapter, and the TBI. Connect the thottle linkage. You may need to add a new linkage ball to the TBI unit for this. Install the CTS in the intake, and the MAP sensor on the firewall at the same level as or above the TBI unit. Next install your wiring harness to the sensors and install your ECM as well. Install the new fuel pump on the frame directly after the gas tank. Now just put in the new eprom that you've prepared to run the system. Try it out and tune to your needs. Try not to screw up and slag your engine.
