Going with the Megasquirt ECU is the way to go! A lot of these older EFI computers are starting to crap out, and no amount of playing capacitor changing hokey-pokey is gonna solve the issues.

It's called "Digital Fade" or "Digital Creep" and it's what you get when the original software in the PROM, EPROM, EEPROM, or EROM, starts to degrade, and the program and/or map have bad data. It's been a serious problem with the classic computers (1970s & up) as well as early digital vehicle control modules.

I've been programming since the 1970s including burning proms. I've programed thousands. Yes, proms can fail, but "digital fade"??? No. Bits almost never get corrupted. There are checksums to catch that. You're blowing smoke

Everyday we learn something new. We so appreciate you. Nothing better than digging into problems. That said, it is fun unless you are rushed.

That's awesome that you were able to find not only a real solution to the problem but a customizable one at that. I imagine that having that sort of control over the programming might allow you to not only improve performance but also fuel economy potentially. I'm excited to see what you end up learning.

Hello Ranger my old friend. I've come to work on you again.

Had no idea that for a vehicle that old you could get a modern ECM. Props!

Sarah, please watch you hair with running vehicle. Tie it back maybe. I've seen what can happen. Love all your vids, wonderful presentation and respect your ability. AWESOME!

I can feel a bit of your pain. I had a 2009 Chrysler T&C that needed an ECM. Dealer wouldn't sell it, found them on the net at the "Rebuilt" places... after doing some research on the companies that were doing the rebuilds, I found that most had poor reviews and most had many complaints with the BBB. So I looked on ebay and found one from a wrecked van for $25. Dealer had to reprogram for $125 and it worked great. Don't trust people just because they have a "business" on the internet.

Glad to see your grandma truck back on the channel.

Once again, I'm impressed by your dedication to bringing Gram's Truck up to spec. Your OCD is on full display, but in this case, probably necessary just to be persistent enough to get to whatever little glitch is making the problem in the first place. Looking forward to the next installment.

I thought I suffered a little OCD when restoring my cars but I have nothing on you Sarah! Great video and you should be proud of your builds. Watching from Australia 🇦🇺

Last time I used jumpers was setting up IRQs on a Sound Blaster and a NIC some time in the 90-s. Jeez, I'm feeling old 👴 Seems like a proper way to easily configure a stand alone ECU for a 94 truck, though 👍

great video. its cool seeing you do stuff step by step.. hope charlies better soon..

Thanks! I wish you and your gang a Happy Thankgiving And Charle feels better soon

Saw this truck going down my street a few weeks after you finished it

Great video - Its a cross between an Agatha Christie mystery and hot-rodding

major upgrade! I love when something old is made current in machines. Thanks for sharing the journey!

Very educational, keep at it, configuring a modern ECU is something few will tackle on a 90’s vehicle, don’t sell yourself short, you’re brilliant.

Great episode! We are all smarter for seeing it. Watching you geek out over tech is awesome, and Charlie is always a great addition to your already excellent content. Keep it up Sarah!

Love a Charlie to the rescue moments!!! He's a mint flavored life saver!!!

I want to personally thank whoever gave you that pointer finger thing because it is hilarious.

You are one tenacious human!! Love it!! I learn more and more with each new video from Your fantastic channel. Keep the great videos coming.

So love this truck and your touch you've given it.

You are amazing! Your passion for this is something more of us need in our daily lives.

Old capacitors can be a real drag. One of my hobbies is restoring vintage radios and test equipment. Some of those old capacitors used oil-impregnated paper as the dielectric and encased everything in a cardboard tube dipped in wax. Their failure mode can (literally) be explosion!

Every project is more and more interesting! I learn so much from watching your work. Thanks.

I had one of these with stick shift and two wheel drive. I used giant slabs of marble countertops that were the cuts from a place next to the auto body shop I worked at. Loved that little truck and did pretty well in the winter with the bed loaded. and yes Sarah your channel still rocks.

Also, note that this ECU has an "auto tune" feature so once you've got the wideband wired in and calibrated, you can enable this feature and once the engine is warmed up it will dial-in the air/fuel ratio for you while you just drive around. How to enable this feature and use it is also covered on our support forum.

Great video, Sarah. This video is a testimonial to how far electronic engine control has evolved. It makes complete sense to upgrade to modern electronics that can be monitored and tuned. Looking forward to seeing how the final result turns out.

Nice work Sarah! I have found O2 sensors and PCM's causing rich conditions intermittently on these, remember it well from back in the day. Not many left on the road so it's been a minute.

Hi Sarah, I am so impressed with you, You are a very intelligent young Lady. I appreciate your desire to achieve perfection with everything you do. I thank you for sharing these videos with us. I have watched and enjoyed everyone of them.

I'm always down for Grandma's Ranger. It was my favorite KZread project, just ahead of Matt's Off-road Recovery restoring Ed's Golden Nugget.

Hugely thorough, well done!

That is so cool to have your grandmother's truck. A nice truck at that.

Outstanding Video I went through similar experience with a 98 Corvette LS1 when i put in a 2001 PCM and had to repin two connectors of 150 pins each then restart via security protocol. When the engine fired I ran out into the street about 10PM screaming "ITS ALIVE!!!!" and my neighbor yells out "Yeah we heard it start!, No go to bed!".

Tuning is always tricky. Thankfully though you e got resources available to you. No worries. You’ll get her running better and smoother than the old school ECU. 👍🏻😎

Hi Sarah, I would happily miss an episode just to hear your comments while doing a tune, a source of humour, I'm sure.

Wow massive change of that old Beatle!

Nothing more to say other than:Dog Gone... Sarah: You are absolutely Remarkably Amazing! J

Awesome video, loved the explanations. Charlie is amazing

You are just friggen dreamy. All that and mechanically inclined. Great entertainment. Thank ya much. P.S. That black outfit really works for you.

When the temps here in the wintertime get below 20 degrees my 94 runs super rich as well until the system goes into closed loop. Hope the next episode comes up with a simple cure. The check engine light comes on as well.

This is so cool to see a MS install. I built a Megasquirt from a kit, learned how to solder and installed in a 80's VW rabbit. massive learning curve. the Microsquirt was out of my price range but considering time is money, it's the better way to go.

Meow soundtrack when mentioning the toasted cats, that's attention to details right there 😂

I would LOVE to watch a series of you learning to tune!

10:24 Lacuna Coil reference. Love it Sarah - LC is one of my favorite bands! I've seen them every time they've come through Denver in the last 15 years!

For a fleeting moment - I thought the box was donuts to celebrate 😂

Watched this video with extreme interest! I have my Gramps 1987 Ranger, fully original factory gleaming glory, that currently has zero issues other than a radius bushing squeak. I never knew such option existed, and will look into this as a back up if the OEM ECU fails!

That became an expensive truck. What a pity. Its a nice looking rig. You did an awesome job. I am glad I was here to see it

Glad to see the Danger Ranger back. And Jimmy with the technical support!

Amazing vid! Extremely interesting

Thankyou Sarah for making learning fun. I'm not qualified in any way to comment on your work. But I will say, I really get a kick out of the yellow pointy finger thingy.

your videos are so interesting to watch. thanks for bringing us along.

Megasquirt for the win!

Interesting! I recently inherited a 94 ranger with 4.0 too. Since I got it , it was really struggling. Finally determined the PCM had the leaky capacitors. They will eventually go bad on all of them. Then it goes into limp home mode and performance really suffers. Eventually I did get a rebuilt one that worked perfectly. After that mine ran like a champ!!!!! But it was really hard to find.

@@BillySBC nah, it's like saying "3 pints of month old milk and they're all mouldy! What are the chances?". 90s caps deteriorate, pretty much 100% of the time, often corroding a chunk of the board as well meaning you have to solder on jumper cables across the board. On top of that they'll be other potential snags, such as dry solders and other component failures. Fortunately you can normally just work through any issue until it works, and most components on the board will be generic.

In '97 the plastic intake manifold on the 4.0 was prone to having vacuum leaks where it is sealed to the cylinder heads. On mine changing the seals worked for maybe 40k miles and the second time around the desks were changed again plus a liberal application of silicone form-a-gasket.
