A little info please

Can anyone tell me on the 92& 93 Loyal's, do they still run a Distributer? Or are they computer controled then?

 

Thanks, Bob:-\

Yes, they use a distributor. Ignition is electronically controlled by the ECU.

[Reveeen]

Yes.

 

are they computer controlled?

 

The FI is (fuel injection).

it is an electronic, distributor driven ignition.. you can drop the distributor (and its associated ignition parts) from any carb'ed EA82 into the SPFI motors and it would work fine; you would know better than I what bits are needed to make the older ignition work. The SPFI distributors are totally run by the computer, but they arent "distributorless" systems.

might i amend this comment for it is both correct and incorect. the ecu has to see a signal from the disty to turn on the fuel pump (and to trip the coil, by breaking the field charge at the ecu itself by proxy of the ignition amplifier). the idea stated above will work if you hardwired the fuel pump to be on with the ignition (+ coil terminal or fuse panel) and the mechanical aspects of the carby distributor will trip the coil at the distributor itself.

 

now, what this statement seems to have meant to say is the carb disty will work on an spfi block in a carb application such as using a 93 loyale motor to replace the long block in a 85 carb'd wagon.

 

but yes, the carb disty will work mechanically if you can get around the fuel pump hotwire. make sure to hook up the vacuum and may as well unplug the ign amplifier at the coil. the ecu will most likely throw a crank angle sensor code(as it would when the car is not running)

You could get it to fire up, but the ECU wouldn't be able to set the timing correctly. It would run off the default "limp mode" timing map.

My comment was made under the impression that he is taking an SPFI longblock and running it carbureted. I base this on previous posts from the user more than anything else.

 

question: how did the carb'ed cars know to energize the fuel pump?? there is an international user with a post (should come up just below this one after I place this post, cant recall the subject header) who needs this info; his car was originally FI, now its running carbed, but it appears the fuel pump relay and wiring are still "stock" FI; the pump only runs with the green connectors plugged in. Not having any carbed experience I couldnt help him wire it properly..

On a carb subaru (EA81 and EA82 anyway) the fuel pump is run off a little box on the drivers side kick panel (on LHD anyway) called the "Fuel Pump Control Unit", or FPCU. It runs the pump for a few seconds when the ignition switch is first turns on, then the control unit only runs the pump when it sees a tach signal. This prevents the pump from running after an accident. Being that his car is originally FI, the ECU did the job of the FPCU via a relay. I don't recall there being a relay controlled by the FPCU but I could be wrong on that.

 

Feedback carb vehicles (computer controlled carb) work just like the FI vehicles.

Ok I see I need to be more spicific.

 

I want to use a 93 loyal motor (EA82) in a Trike adapted to a VW transmission. I've done this once before using an EA82 carbed motor. It too had an electronic dist, but I didn't need the computer to run the motor. I used an electric aftermarket fuel pump and bought a standard coil at auto parts store and stripped the manafold of all smog junk and added the Weber kit. Runs like a dream.

 

I want to do another one but the carbed motors are becoming hard to find with decent mileage. I have a carb manafold to use and would use a Weber carb and will use an aftermarket fuel pump too just like the first one. My question is, will it work the same as the 85 carbed motor I have in my other Trike. I will not be using the computer or any other part of the wire harness. I will strip it down to a bare manafold and run it like the other one. Will it Work?

That is exactly what I had thought.

 

The answer is, that you will need to piece together the ignition system from a carbed model (*I* am less than 100% clear on exactly what list O' parts, but I assume you would know this better than I) but that dizzy will drop right into the SPFI longblock.

 

If you were to totally ignore all the auxiliary crap on the engine, and focus simply on the longblock, then the SPFI engine will work great for your trike; you just need to get all the ignition equipment off of a carbureted model. The SPFI engine is slightly higher compression as well, I think it is 9.0 (carbed) to 9.5 (SPFI) but the carb may even be slightly lower.

Thanks for your feedback on this. I do have the Dist and manafold from a carbed model. I just didn't know if the Dist on the loyal would need to be changed and if the one I have woyld fit ok. If it will then it looks like I can use the loyal motor ok for my project.

 

Thanks, Bob:banana:
