Rockfrog Posted February 9, 2019 Share Posted February 9, 2019 I'm interested in learning mor about that external voltage regulator. I have a 136A WJ alt I want to toss onto my 88. Sent from my SM-G930W8 using Tapatalk Link to comment Share on other sites More sharing options...
mnkyboy Posted February 9, 2019 Author Share Posted February 9, 2019 It's pretty simple really, there's also many write ups and videos about the conversion. You can find kits with wiring and all for $50-$60, or source the parts yourself for around $20, even less if you can snag a used regulator and plug.

mnkyboy Posted February 13, 2019 Author Share Posted February 13, 2019 The Speeduino ECU showed up today, now to figure out how to wire it up and get it to work. Link to comment Share on other sites More sharing options...
Darren Posted February 13, 2019 Share Posted February 13, 2019 Get to work. I'm very interested in that. Link to comment Share on other sites More sharing options...
mnkyboy Posted February 15, 2019 Author Share Posted February 15, 2019 It will be a minute, I've still got a ton of research to do,i also still need to get the Continental out of the garage to make room for the MJ. I did order some IDC40 ribbon cables to build the adapter to make the Speeduino plug into the 91 MJ harness, once i make it, i will have the boy design and 3d print a housing to attach the connector to the housing i got to hold the Speeduino. I also got the 36-1 trigger wheel ordered to put on the crank since the Speeduino can't read either of the available 2.5l trigger patterns off the flywheel, (FYI there is code to support the 4.0l HO pattern so it will be easier for someone to convert a 4.0l.)

JMO413 Posted February 15, 2019 Share Posted February 15, 2019 Wow. That is one awesome rig you have built there. Just got done reading through the whole build. Keep up the awesome work. Can't wait to see it with the stand alone. Link to comment Share on other sites More sharing options...
mnkyboy Posted February 26, 2019 Author Share Posted February 26, 2019 Another puzzle piece showed up, now i need to set this up on the crank pulley and relocate the crank sensor to read it. I also picked up a new laptop just for tuning and various electronics projects, it's fancy enough to run everything i need but cheap enough to hang out in the garage. Now I'm waiting on some cables and a breakout box so i can start playing with sensors on the Speeduino. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 8, 2019 Author Share Posted March 8, 2019 A while back my son made me a hood ornament, it came out good but looked a little too small with the supercharger sitting behind it. So he upscaled it and made a much larger one, the new one seems to fit the truck better. Link to comment Share on other sites More sharing options...

I like the color for sure Link to comment Share on other sites More sharing options...
mnkyboy Posted March 8, 2019 Author Share Posted March 8, 2019 It's the Convoy/ Deathproof duck, it does look a lot like the Oregon duck though. Since i live in Oregon, I'm sure many people will think it's the U of O duck, not that that's a bad thing, maybe i should add a beaver to even it out.

Hmmm, sounds familiar and definitely looks familiar. I like it, a jeep 2.5l with super charger and tough duck! Link to comment Share on other sites More sharing options...
mnkyboy Posted March 19, 2019 Author Share Posted March 19, 2019 Finally got my Lincoln moved out of the garage and the MJ moved back in, tonight i decided to remove the rear flares, I've gone back and forth about it and finally decided to just start cutting. Now i have all sorts of room for activities, might have to get some 40s for it. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 20, 2019 Author Share Posted March 20, 2019 Spent a couple hours in the garage tonight and made a sector shaft support for the MJ, it still needs a little more work to finish it, but should work pretty good. Link to comment Share on other sites More sharing options...
Pete M Posted March 20, 2019 Share Posted March 20, 2019 I was wondering why you kept the bit of rear flares. looks good Link to comment Share on other sites More sharing options...
mnkyboy Posted March 20, 2019 Author Share Posted March 20, 2019 As the Jeep grew, i just kept trimming away at the flares. I planned to eventually remove them but didn't get around to it till now. It looks good but different, it may take me a while to get use to it. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 23, 2019 Author Share Posted March 23, 2019 Tapped the last holes so now the sector shaft support is all bolted up, now i get to take it all back off so i can pull the steering box to install the hydro assist. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 24, 2019 Author Share Posted March 24, 2019 I had the Jeep out so i snapped some better pics of it with the trimmed bed. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 30, 2019 Author Share Posted March 30, 2019 Got the assist ram installed, i need to machine an internal stop for it but the placement looks like it will work pretty good. Also got the tapped steering box put in, which is a pain in the butt with my hidden winch set up. I couldn't get the Bluetooth hydraulic hoses to work, so i took some measurements so i can make a set. Link to comment Share on other sites More sharing options...
mnkyboy Posted April 5, 2019 Author Share Posted April 5, 2019 I finally built some hoses and machined the spacer to go inside the assist cylinder. I've got all sorts of steering power now. 20190404_172356.mp4 Link to comment Share on other sites More sharing options...
Pete M Posted April 5, 2019 Share Posted April 5, 2019 oh, i bet that's nice. there were plenty of times on the trail I needed that kind of boost. (curse that minispool!) Link to comment Share on other sites More sharing options...
A-man930 Posted April 9, 2019 Share Posted April 9, 2019 Gotta love having a lathe! One of the best garage investments I've ever made; right on par with a welder. More pics of that sector shaft support when you have it off please! Link to comment Share on other sites More sharing options...
mnkyboy Posted April 13, 2019 Author Share Posted April 13, 2019 It is a handy tool to have. I already took the support off and put it back on when i tapped the steering box, but there really isn't much to it, i basically put the bearing on the sector shaft and started connecting the dots. My front end is already plated so I just tied into the existing plating rather than building a crossbrace like the off the shelf supports use.

mnkyboy Posted July 13, 2019 Author Share Posted July 13, 2019 My distributor has had a nasty wobble to it for a while, i finally dug in and found the issue. Besides the broken pump drive, i found that when i put in the new pump it was having binding issues similar to the old pump, i pulled the locating dowel and found it was damaged and looked like it had been installed incorrectly at some point, i swapped in another one and the new pump turns nice and smooth.

itschrisb Posted July 26, 2019 Share Posted July 26, 2019 This is my first post on here and wanna say this build thread is amazing. So glad you stuck with the 2.5 too. I just picked up an 86 MJ with a 2.5 so this is a huge inspiration. Keep up with the updates. My buddy used Speeduino to tune his supercharged Miata and it seemed to work really well. There isnt nearly the same support as megasquirt but after the initial setup it's pretty easy. Neither one of us ever tuned before and we got it running pretty well.
