I noticed the temperature gauge was close to the "C" mark. This era of Ford computer generally won't enable adaptives (learning mode) until the engine has hit 160°F. Closed loop will work prior to that, but no long-term corrections will be committed to memory. Additionally, the "test" ECU you used was labeled 5.8. The 5.8/351W of that era had 19 lb/hr injectors. The 460/7.5 had 24 lb/hr injectors. So any given pulsewidth to injectors would be injecting much more fuel than anticipated. It would inherently run very rich with that computer, and even in closed loop it might not be able to fully compensate.

The oxygen sensor needs heat (400C/750F) to produce energy (voltage ). So, if the sensor doesn't have a heating element, it may take several minutes before it becomes fully operative. It's up to the ECU software to figure out when the oxygen sensor is hot (temp sensors, fixed delay, etc ) so it can start reading the sensor and bring the ECU into a closed loop. Anyway... Thanks for yet another interesting video.

Sometimes, to "reset" an old ECU, you need to not only depower it, but also short the power leads to it as well. This also applies to OBD II's now and then, as I had a Jeep Grand Cherokee ( 2000) where my battery was going weak and although the engine ran, it threw a low voltage code. I disconnected the ECU / PCM fuse, shorted the input power lead to it, towards the PCM, and when I reconnected and restarted it, it saw the low voltage as its new baseline and was happy until I got it home from PA to Chicago, where a new replacement battery fixed all of the associated ills

40 years ago I had a 1981 Chevrolet Citation that ran like a top. One day I go outside to start it and it cranked and cranked and would not fire. I did all the obligatory inspection for a failure point to no avail. Then I thought about how cars were having computers in them around that time and I suspected the ECU in that model was at fault. I didn't even know where it was. After rummaging around under the hood and dash, I found it tucked away behind the glove compartment. I popped it out and brought it to my ham radio service bench and opened it up, not knowing what to expect. There, staring me in the face was a thick board trace that had popped. I checked north and south of it for any component failure, finding none. I scraped and bridged the trace, soldering a bare copper wire across the gap. Put the unit back in the car and it fired up immediately. I had ducked a bullet. My guess is if I had to take it to a dealer, it would had been an excruciatingly big ticket item to fix. A few hours on a Sunday afternoon, a piece of wire and some solder did the trick. I kept the car for another several more years of great service and gave it away to a friend who needed a ride. If I wasn't a ham, I would have gone to the cleaners. Thank you Shango for showing the potential of repairing old tech. In your case you know what you are doing. I only got lucky in my case.

EEC-VI closed loop story: I found my 88' Ranger went into closed loop almost shockingly fast with a cold engine (60 - 70 sec at 40 - 45 F), with a new O2. Then closed loop would randomly start taking forever. The heater in my replacement Bosch O2 sensors was burning out really fast because EEC-IV have the heater wired directly into key on power, not through a relay to switch off after a certain temp. I don't think the replacement elements are up to the oddly high duty cycle. The sensor works without the heater, but is difficult to bring online, & quite lazy when cold. I found unhooking the O2 heater after reaching operating temp didn't effect the sensor reading and am planning to film making a modification to add a temp dependent relay to my EEC-IV to stop the consumption of these 02 heaters. (I rarely reach operating temp) Fun Fact: When changing altitude significantly after startup on EEC-IV management, always cycle the ignition to update the computers altitude/barometric reading. (as you stated this happens during after KOEO before KOER) I have also installed a O2 gauge in the dash in the quest to learn the throttle magic required to activate the Ultra Lean Burn feature of EEC-IV, where under the right conditions the EGR commands are be perverted to cool the otherwise disastrously lean condition the EEC can apparently adopt when the planets are in the right retrograde and the Schumann is 7.3Hz. (apparently different than a regular NOx quash dousing, and seemingly would undo all the NOx saving done in the other regular EGR mode)

Shango,Interesting video.I’ve seen a couple of your others on car ecu’s where the traces were really badly damaged by capacitors and you got them working. I bet you’d have a full time job if you decided to take on repairs for other people doing just these car ecu’s. I’m so glad that I’ll never have to deal with issues like these since I drive 50’s and 60’s cars. Just rebuilt the Carter carb on my 1958 Plymouth the other day after over a decade of service. Kit cost me all of $15.00 and I did the work myself. Cars have just become so needlessly overcomplicated these days. Computer controlled transmissions,computer controlled everything. Transponder keys. Computer controlled ignitions. Even though this is an older car (I think you said it’s a 92) it’s still new enough to have these kind of computer problems,although the ecu did last 32 years. It’s just a shame that even though the car is (presumably) mechanically sound that something like this took it out. I realize the manufacturers don’t plan on people keeping cars 32 years,but A repair like this would be beyond most owners ability or knowledge. They would either junk the car and go into debt buying a new one or have to take it to mechanic and bend over and grab their wallets. I’m sure they would charge at least $1,000 to replace it the ecu, Likely more. The late 80’s and 90’s cars seem to be much more mechanically reliable than the newer cars. More and more these days it seems people just stay in continuous debt leasing new cars and then dumping them every couple of years before the onset of expensive problems.

Maybe if enough of those guys get together and are vocal enough they will change the exemption year. Prior to Gov. Schwarzenegger stopping it,California had a rolling smog exemption where any vehicle 30 years old became exempt. I always wondered why he did that.

Bad connection? I had one do this and the voltage dropped low enough it would reset the ECM when it cranked. Also some of the heavy duty emission vehicles we had here in Alabama and Tennessee would run in open loop at idle. I'm sure that's not the case in California but I remember chasing an open/closed loop problem 30 years ago on one and finally got on the tech line to Ford and they said it was normal to fall back into open loop at idle. Go figure. Great looking van. I'd love to have it. Sounds great! Thanks!

I like how you've got a dyno and exhaust gas analyzer, but no scanner - the most basic tool for doing computer stuff. Not totally necessary, but it would've been nice to just look in the datastream to see if it was in closed loop or not. Or to see if any data items were out of whack. If you're doing enough of these old cars, I'd definitely recommend picking up an old scanner, like a Snap-On "brick." Also, these old computers have Keep Alive Memory (KAM), which gets erased when power is disconnected. When it's erased, it has to learn everything about the engine all over again, and just runs on default factory values until it learns. Especially important, since this old engine is probably worn out and all kinds of different from when it left the factory.

The trace to the left of the one you found that was open also looked suspect.

I'm not yet sure where my problem lies . I am blowing the maxi fuse in the number 9 position which is a 30 anp fuse . The truck is a 1996 7.5 460 with automatic E40D . Have you any ideas you might share to spread some light on things ? I would be glad to ship it to you if you're interested. This is a 109k truck and is above average for a gasser .

Seems like you could use a scan tool that will get live data from the EEC-IV ECUs - might be able to pick up an older Actron unit with cartridge and cable (CP9110 + CP9112), for cheap'ish on ebay these days.

Only certain later EEC-IV vehicles had live data available. I believe the trucks and vans had it in '93, T-bird and cougar in '91, Mustang never had it until it went to EEC-V / obd-2 I have an OTC Monitor 4000 that I use for anything pre-95 that works fantastic, better than the emulator that's on my Matco Determinator (OTC Genisys 5.0 clone)

Can a PCM this be faulty if there is no leak. No burnt? If vehicle is misfire. Transmission shift problems?

Can you do ECM swapping for a couple of years newer? Example using your 92 E350 install a 96 F350 w same engine size and transmission model?? great video!

This one time I replaced my injector with a chinese ebay one. It was a good thing i had inspection a few days later because the CO was over 15

Excellent Video. I'm trying to remove the ECU from my 1995 E-150 Club Van. One mounting nut no problem the second one the stud keeps spinning can't get the nut off. I looked inside above the gas pedal and I see the computer. How should I hold the stud/bolt?

So where do you send an ECM to have it repaired ? Or where do you buy the parts to repair them ?

Something to be said for OBD1 ECM/ECU 'learning' after power loss and volatile ram is cleared. :)

Nice analysis and repair. Quite a few miles, if the odometer's accurate. What brand electrolytics are less prone to leaking like that?

Do you happen to know if there's a difference between 93 and 94 eec with a 460 automatic
