    1992 Mitsubishi Mighty Max Build AKA Mighty Ruckus Carrier!

    Recently I pick up a 92 Mitsubishi Mighty Max ,with the 2.4l and automatic transmission, for $500. I bought it not running and trailered it to my shop to begin the build / get it running. I was told that the crank timing sprocket was worn out, keyway wore a notch, and it just needed a new gear and it was good to go. Well lets just say I found a little more than just that wrong. Pics Below are when I got it and what I was told was wrong with the new part! Also Posted is what the truck will be transporting! (warning pic heavy!!)Click image for larger version.

    Here is Progress on day one (Currently on day 4 or 3...I'll just say 3..but I finally have time to get the thread going) got the Illusive crank timing sprocket in at the dealership and finally have it installed in the truck and retimed the engine. Got the truck started after a quick shot of starting fluid in the intake. It runs ok but it runs very very rich and all 4 spark plugs are black and smell like gas pics below, also found a leaking water pump! Click image for larger version.

    Day 2/3! Holy Progress

    Picked up a lot of parts and my amazon order came in! Full tune-up (wires, plugs, fuel filter, coil, rotor, water pump, rad hoses), and tail light assemblies. All that got done today was Removed old water pump, removed and install new plugs, wires, and coil. On day 3 New water pump installed, upper and lower rad hoses installed, tps checked and reading properly, retimed engine (again lol), new battery installed. Got the vehicle running but still running rich. Pulled ecu and opened it up and found this. (see last pics) Going to have to see if I can repair this and clean the board up quite a bit!

    Progress on day 2: on day 2 removed water pump, installed new coil, wires, plugs, rotor, and tail light assemblies. Progress day 3: Installed new water pump, radiator hoses, retimed engine (again lol), checked tps signal, installed new battery and got the truck to run but still running the same as before (super rich) so I pulled the ECU and found this pics below. looks like its time to rebuild the ECU ECU.

    I meant repair the ECU. On the underside of the board there is a point where the copper pathway is broken and on the top side it looks like a cap might be leaking slowly and there is a decent amount of corrosion on it that needs to be taken care of. So I guess that's where the cleaning comes in since who knows what else has a broken connection....LOL. Need to see If I can save it of not. I believe that is why I'm running so rich!

    RUCKLIFE!!!! TotalRuckus Much? I had to rid myself of my Ruckus. Local Law enforcement kept asking how a 50cc bike could run 62mph. PWJDM Stretch Kit and a 150cc motor doesnt look that big........ Welcome to the forum and Be Warned, These trucks are more additive that the Ruck's!!!

    Those plug wires 8 or 9 mm? They look huge...I'm wondering when the plug wire companies are going to stop making bigger and bigger wires. I remember the good ole days when they were 3-4mm and oh my god they worked too, lol. Marketing is everything nowadays.

    Great catch on the ECU, Never would of found it if you didn't look. Great job on details. Use to have a girlfriend that was a Ruckus, Them Italians are something else.

    Haha yeppp and luckily mine is still a 50cc right now but it will do 50 no problem and I am building a 150cc ruck as well so we will see how that goes. Glad to be apart of the forum! TotalRuckus and my rucks are getting jealous of the Mighty Max!

    8mm I believe, they are pretty big and I've asked myself the same thing lol. The only reason I looked at the ECU was from looking on the forum and seeing that they cause issues. Otherwise I probably would of never looked there....So thanks you guys!!!

    there should be values on the sides of each capacitor that tell you what they are - for example 1000uF at 20 VDC. Just get those numbers and google them to buy them - highly unlikely RadioShak will have them. Try Digi-key or Great Plains electronics once you know what you need.

    Is that for a 4g64 ECU or is that for all ECU's?

    I am getting ford parts like that delivered. I'm just starting to think about that I have to install all this stuff too!

    You know we have a Thread all about the ECU and how to repair it here.

    Well I pulled the capacitors and C104 says 47uF @ 50v (in red) and C105 is 100uF @ 16v (in blue) C104 is that supposed to say 50v or does that mean 5v? pics below as well. The caps we definitely leaking! one even lost its leg!

    go with what you find in there - the voltage and uF rating can be higher if it fits, but neither can be smaller. Not a suprize with Rubycon caps - they used the same ones in many coin op games in the same timeframe.
