Absolutely, Domspun. That sounds like a good idea!
As I'm moving in a couple of weeks, and no matter what, I have to get the Lorelei on the auto trailer, I think I'll wait until I'm safely at the next residence to tackle this. This will give me some time to get a junkyard ECU and try my hand at it, to test the concept and build my skills.
I could see going as far as getting a second Gen2 3S-GTE ECU and recapping it--I did get twice as many capacitors as I needed--and then seeing whether it works when I throw it into the Lorelei.
As for the caps I got, the Nichicon is rated at 3000 hours at 105°C, and all the others are Panasonics rated at 5000 hours at 105°C. These were the brands and types recommended in multiple threads and as I recall underscore went with Panasonic EEUs for the most part for his recap job. The Nichicon is the correct microFarad rating and overstrength on voltage which I was told was acceptable or even a good thing. But I have Panasonic EEA-GA1V150B 15µF35V capacitors which I assume worked for underscore, as a backup if I come across information waving me off using the Nichicons. I just wanted a long endurance capacitor to set the ECU up for as long a life as possible before it dies.
To test a theory I had, I cleaned the electrolyte the capacitors puked out onto the board with vinegar and then cleaned the area with denatured alcohol. Then I closed the ECU up put it back in and took the Lorelei for a 22km loop.
No CEL. So, I figure I eliminated the ground fault that was causing the CEL to light. I'm not observing any grave irregularities in how it runs. I don't know how much time I bought by doing this, but probably at least enough to make it to Colorado and then approach the deed on my own timeline.
