I screwed up big time....

[dave]

I was just thinking. Years ago (maybe 40), a friend of mine was repairing circuit boards for computers. He did this for the college campus computers because they were broken, nobody else knew how to fix them, and they were going to be trashed anyway. Now this friend is extra-ordinary when it comes to things like this, but maybe it's possible to find someone to repair an ECU today? I understand circuit boards have become much more compact and miniaturized, so maybe this is not even feasible today. Any thoughts?

Yes- most things are tiny and on-board- completely different than a few decades ago.

And these are also sealed 'non-serviceable' units.

Hello PowerDubs, I am so sorry this happened: I know how expensive this will be. Your situation, and a situation I am experiencing now, has prompted me to ask the following question to the forum: I am having difficulty finding OEM parts for my 20 year old Honda VFR800 right now - simple parts like a mirror, plastic, and believe it or not, mounting bolts to attach the mirror (yes, one official Honda distributor listed these common bolts as unavailable). What is a person to do when an uncommon part, such as the ECU or any other electronic sensor or control breaks and an OEM part is no longer available? After market manufacturers don't supply most of the electronic components our modern bikes use, and I don't expect to find many CB1100 parts through wrecking yards. So, if an ECU fails on a CB1100 in 8 or 10 years from now, and Honda says "So sorry, part is no longer available", do we just park our bike in the back of the garage and forget it, or advertise it on Craig's List?

There will be more bikes that are crashed and become parts bikes than there are failures of electronic ignitions or ABS modules or other essential parts.

That's why a forum like this is so valuable. When there's a need, someone will have it, or know who can make it, or know a work-around.

If one can determine the functional requirements of the ECU, it is not unrealistic for somebody to build an emulator - say maybe using an RTOS on a Raspberry Pi Zero (if that meets specs) - and program it appropriately.

Think of it as a heart transplant with a machine version.

I think the hard part is getting the ECU requirements. This is the Honda proprietary sauce. This is not just the parameters, but the functional algorithmic units too. Once that is known, emulation is a re-engineering exercise.

I'd rather a fried ECU than a melted undetectable area of the bikes wiring harness.

Still super po'd at myself.

So the case on the power commander and autotune box both pop open easy enough- but both sealed solid construction inside.






No sign of heat, bubbling, smoke or anything on either one.

Since my garage computer can see the power commander when I plug into it- and gives no errors- I’m guessing it and maybe even the auto tune box are ok.

So- I need to figure out where the smoke and sizzle in the battery area came from.

PowerDubs : WE are supposed to do things like that , NOT a smart person like YOU !

[GoldOxide_imp]

Looks like a good thing PD.

Maybe you won't have to donate your ECU "to science".

[PowerDubs_imp]

Can't for the life of me find anything that seems discolored, melted, signs of heat, etc- all fuses good, diode tests good on meter, swapped relay positions in the fuse box.

I guess I wait for the new ECU to show up.

In the mean time if anyone has any suggestions...I'm all ears.
