TBI Conversion Computer Removal
« on: July 22, 2016, 01:33:51 PM »
Does anyone know if I can remove the computer that sits inside near the passengers right leg? I want to put the new TBI computer there if I can.   I'm not sure if this is part of the starting system as well. 

Thanks!

hi, if you are not using the stock BBD carb, distributor, and all their related sensors, and I gather you are not, then you can remove the computer. What year is your Eagle? 83- the computer controlled only the carb; 84+ it controlled both carb. and distributor. What kind of TBI are you using? good luck, gz

I have a 82 sx4. Thanks fot the info.  I found the guy on ebay called Performance fuel injection.  The kit is a grand. It comes with everything you need. She's running pretty well. I haven't really been able to road test it yet. I'm in the process of hard mounting everything at the the moment.  Need to fab a kick down rod next. So far so good.

Here you go.  The wiring still needs to be cleaned up a bit.  The fuel pump was pretty straight forward. I bought 15 feet of FI fuel line for the inlet. I mounted the pump on the back side of the rear seat pan so it's sitting perpendicular to the car frame. I originally had it mounted the frame but I was concerned about the how much weather and other things it would be exposed to so i put it up higher. The directions say, as as the pump is mounted even with the lower  25% of the tank you are good. Seems to work fine for now. Again this is all pretty new.  The TBI unit has an inlet and outlet for gas.  I just ran the inlet hose along the frame and used plastic ties to hold it in place.  The direction say to time it to advance the timing 8 degrees at 650 to 750 idle speed.  She runs  bit rough but starts and revs up fine. Seems to have plenty of power. I'm not sure if I have a vacuum leak someplace or what.

I ran the electrical through the inside along the floor board and drilled a whole just above the fuel pump.  And that's all she wrote.  Pretty simple. It just took a while to plan it out.

I don't believe you need a vacuum advance once you go tbi. The computer should do the work now.

Very nice.  Thanks for the pics.  I've seen that TBI setup on eBay and thought maybe someday I'd give it a go.

It's rock solid.  I've moved to Washington state and drove my Eagle  from  Chicago with no issues.  She's been running all over the mountains like a champ.  I've put about 8k miles on her since the TBI.

I've had no failures of the system at all.  I've been using her as my daily driver. She starts instantly every morning, idles up fine. 

I would buy again.

I've been thinking about putting a 4.0 head and MPFI on in the future.  But if you want to keep everything stock and want the performance of a FI this is a great way to go.

The only thing I would have done differently is upgraded to a 4 barrel setup before I ordered.

Thanks for the info you've given me so far on this swap.  I bought this system also and am just getting geared up to install it.

I had a 4.0 head installed on my Kammback a few years ago, so this will mate up with that, I'll let everyone know the results. 

PS, if you're thinking about buying this setup, they usually have a Black Friday sale of $100 off after Thanksgiving.

I have their tbi setup on my Grand Wagoneer and it’s been great. Thinking about getting it for the Eagle now. Good to hear some positive feedback from you guys about it.
