In 4lo and needing to stop early in the climb when it stalled..... It is terribly frustrating to get stuck like that when the only way up is winching... and the truck won't start or run to assist the battery for winching or climbing... and I had the hand throttle pulled out plenty far... no joy.

Time for fuel injection!

Yeah but I think that is a pretty extreme case. Really depends on how you are going to run your truck, many of us wont be running trails that extreme, let alone in 4lo. I really believe that is where the vortec/efi/etc. swap comes into play. For me I am more concerned about the fuel efficiency, little bit extra power but more importantly the convenience of just going out (regardless of temp) and having her fire up on the first try.
 
"many of us wont be running trails that extreme, let alone in 4lo"

But that is my exact use case... Maybe I should just sell the truck, stop rock crawling and grow old gracefully... (I'm being serious BTW)

No, keep playing with it til it makes your last hair fall out, park it and resume when you miss it again.

This kit has been on my radar for a while and I have talked with a few of the guys in the 40 section about it. Seems everyone has really good things to say about the kits from AFI and their customer service for issues. Also believe that @tat2matt is running an AFI kit on his 60. Talking with some of the guys in the 40 section, some have reported upwards of 16mpg avg however the 40 is much smaller and lighter, but that was with a few pieces of armor, bigger tires, lift, etc., so possibly equaling the weight of a stock-ish 60??

I WAS running an AFI kit. I had the ECU fail on a train outside Estes Park and had to be towed out by a JEEP! I pulled the TBI and had Jim C build me a carb. Although he did a nice job I really miss the TBI. I have talked to a bunch of people that would say the Howel is better than the AFI and some people don't like the DUI dizzy but I never really had any issues. I had my ECU rebuilt and will put it back at some point.

But where is the fun in that? "We don't stop playing because we grow old. We grow old because we stop playing."
If that is the case then call your local raisin ranch and get your seat at the table now. Are you seriously crawling that much and that often and on such extreme trails REGULARLY that you could warrant the need for EFI? Or is it simply that you are looking for something to do and this has been an annoyance in the past?

Maybe it is time for a "purpose built" rig vs. what you have now.. Like go find a moldy, rusty cruiser somewhere and turn it into an exo'd crawler?!

I really am hesitant to add a computer to such an analog truck. I know carbs can fail, but at worst with a carb you can keep manually pouring fuel in or spraying starting fluid to move the thing.

Did you buy the kit new? What failed? Did AFI fix it?
 
I have never had my tbi leave me stranded. I've had malfunctions but not ever stranded. I would say first research some of the universal tbi wideband kits like the holley sniper. If those are dead ends I would go AFI but convert the FJ60 distributor to work rather than the dui. Make sure u tell AFI your intentions so they give u the right chip programming.

No. I don't get into stall conditions that often. I was hoping there was a solution for a few hundred dollars... $1200 does change my inclination (pun intended) to make the change. I'd sooner spend that on bumping up to 38" rubber!

Yeah from my research your best bet is to get your carb tuned perfectly and you MIGHT be able to avoid that situation but others there is no EFI/FI solution for only a couple hundred bucks. All of them start at about $1300 and go up (with accessories and what not you are closer to $1600-$1800). If you truck is in good running condition and you plan on keeping the engine for a while then why not go for it? 38" rubber sounds cool but if your engine can't turn it on anything but flat ground then is it really worth it??

My engine still runs good enough and I dont use the truck for much that I dont really NEED a v8 however I do have a piggy bank going for the eventual swap. In the meantime I am saving up the money for the FI because I figure I will have that for probably 5-10yrs before a bigger swap.
 
BTW carb is a Chenoweth rebuild that Jim tuned on my truck. At the angles I'm taking about the carb SHOULD fuel starve...

There's this cool thing called gearing, and @woytovich has it.

Why do you say to use the FJ60 distributor? Convert it how?
I have an FJ60 distributor that I could use om my early 2F, but had just planned to get the electronic controlled distributor that comes with the AFI kit, for hopefully plug and play. No good?

You can use the air distributor which is easiest. Or u can convert the fj60 distributor if u have the one with the magnetic pickup in it. The fj60 distributor is higher quality but more work to convert. Their are several writeups on how to do it floating around the internet if u do a Google search. It's not too hard to convert. Set timing to 0 degrees. Remove distributor cap and Mark the distributor body in relation to the advance housing. Then remove distributor weights. Lock the housing to advance housing with your Marks lined up. I locked mine with liquid steel. You could try a tack weld instead. Then your done. Connect the pickup coil wires from distributor to gm 4.3 engine ignition module and coil years 89 to 92. You will need a wiring diagram for gm astro or s10 for those years which should be on the net in various forums as many people with older vehicle's use gm tbi.
 
Is the AFI distributor a converted FJ60 or 62 unit?

The used kit I had contained an electronic DUI unit. I had no issues with it, even in a few deep water crossings.
 
I installed a TBI kit from Affordable Fuel Injection on my 1976 FJ40 over the winter and it turned out fantastic. I wish I would have done it before suffering through all the carb headaches over the last year.
I ordered the kit with the DUI distributor with timing advance connector so timing is controlled by ECU.
It was a bit of work to get it installed, but it now starts every time without issue, good acceleration (relative for 2F) and runs better than any of the carbs I have had on it (which included a rebuilt stock Aisin). It is actually capable of going faster (65+ mph) than I want to take it on the freeway now. Things get interesting above @65mph.
It ran 'OK' for a few months with the rebuilt stock Aisin, but and then took a crap. My guess is that the ethanol gas is just not friendly to the old carbs.

Hardest part to the EFI install was fabbing up a bracket for the throttle cable, which I got from Downey. But a normal FJ40 throttle cable would probably work as well. There was nothing special about the throttle cable that I got. Not much more than a bicycle type cable which was way longer than I needed.

Once installed I had a high idle issue, but was able to correct that with a little tuning. Now idles at 1000RPM when cold and once it is up to temp it idles at 650RPM.
 
That is some good information @fabiodaddy about the bike brake cable working for the throttle cable. On your AFI install did you purchase the standard length (think it is 36" pigtails) wiring harness or did you upgrade the length. That is one of the things that I fear with this is getting the wrong length (too short) and either having to purchase a separate at additional cost or waiting for a replacement to come.
This is still on my radar and like I said, the piggy bank is being filled specifically for this reason alone.
 
Greg, I had the same fear...wires would be to short. I ordered the 48' harness and mounted the ECU in the glove box (didn't want to mount it there, but not a lot of room anywhere else) and everything reached fine. Make sure you put the O2 bung close to the manifold so that the O2 cable will reach. I had to bundle up the excess cable length above the engine and tied it to the firewall. A little messy, but considering how well the thing runs it is worth the minor cable clutter.
