  1. RE92s at 79,500 miles, 7 1/2 years old

    Honda Insight Forum 1st-Gen Discussion
    ^ OK, Boss.
  2. RE92s at 79,500 miles, 7 1/2 years old

    Honda Insight Forum 1st-Gen Discussion
    They're not "totally" done; there's still tread in the center.
  3. IMA Bypass fuse

    Problems and Troubleshooting
    I deleted everything I wrote a second ago as it was all wrong. You don't need the fuse in place to grid charge and discharge, so you can remove it and use it for your bypass. Here's a quick diagram of how the busbars/junction board interface with the battery sticks in series. The fuggly yellow...
  4. P1644, P1646, P1641 plus 12v battery light

    Problems and Troubleshooting
    All those codes have to do with signals between the MCM and ECM. A fairly easy thing to do is to check the connectors on the MCM in the IMA compartment, make sure the connectors are fully seated, pins/terminals are clean, etc., and to do the same with connectors to the ECM under the passenger...
  5. RE92s at 79,500 miles, 7 1/2 years old

    Honda Insight Forum 1st-Gen Discussion
    Had to do an oil change, during which time I always rotate my tires. Took a couple pictures of the tread left on these relatively old tires. Right side is outside:
  6. R1 Concepts drilled and slotted front brake rotors

    Honda Insight Forum 1st-Gen Discussion
    I bought these about 5 months and 4400 miles ago. They came in a pair with ceramic pads, for about $100. I had OEM rotors before and some aged Duralast Gold pads. The pads had plenty of wear left but they looked a bit on the crusty side. I'd drive my housemate's Honda Fit, which had new rotors...
  7. The quintessential Insight NiMH voltage thread

    Modifications and Technical Issues
    Here's a link to a post that goes into the battery management implications of some things I saw working with another fast self discharge cell/stick: https://www.insightcentral.net/threads/oem-pack-management-efficiency-not-so-good.117785/#post-1450808 I posted a graphic there illustrating how...
  8. OEM pack management efficiency: Not so good(?)...

    Modifications and Technical Issues
    Here's a better graphic depicting the concept described above, same data. It's really quite striking and, I think, a good illustration of the potential impact of the whole 'use low charge state' idea, as well as of the benefits of deep discharging in general. Cell C2 (yellow curve) was a...
  9. Quick question(s)

    Honda Insight Forum 1st-Gen Discussion
    ^ That looks fine to me -- if it can put out up to 200V and limit current to whatever value you set. I think in general terms I would set it to 184V.
  10. OEM pack management efficiency: Not so good(?)...

    Modifications and Technical Issues
    I don't think so. I actually think it's the opposite: cells that get driven low seem to benefit from the deeper discharge, consistent with the stuff I've posted around IC about 'deep discharge'. As I mentioned above, I'm working with a stick that has one cell with faster self discharge, and...
  11. OEM pack management efficiency: Not so good(?)...

    Modifications and Technical Issues
    Lately I've been dealing with a rebuild of an old failed rebuild, plus a single stick in my in-car pack that's always had a bit faster self-discharge in at least one cell. This rebuilt rebuild ended up having quite a few fast self discharge cells too. These are making me reassess the...

    Modifications and Technical Issues
    Beautiful presentation. Thanks for sharing all this.
  13. The quintessential Insight NiMH voltage thread

    Modifications and Technical Issues
    I took a closer look at the sticks with 'red-highlighted' cells, the high self discharge cells. I discharged those cells individually to see what capacity they had left given their relatively lower voltages. Although it's clear that all the red cells have high self discharge, given the remaining...
  14. The quintessential Insight NiMH voltage thread

    Modifications and Technical Issues
    Indeed. Yet, I was also thinking that most of the stick voltages are so similar that a value about 0.1V lower could be a tip-off... Problem is, I don't think the typical pack has such similar voltages, plus, it's really only obvious when you see all the cell voltages, plus, if anything, we...
  15. Correct lube for door check?

    Problems and Troubleshooting
    I don't have any definitive answer, though I'd think white lithium grease would be fine. The 'door check' mechanism is something I've been meaning to check out - because my driver side door doesn't hold worth beans (and like yours my passenger door has a loud creak). I drove a very low mileage...
  16. The quintessential Insight NiMH voltage thread

    Modifications and Technical Issues
    Here's a nifty little dataset that might help battery-putzers wrangle with self discharge. Or, consistent with data I've posted before, might show you just how difficult it is to identify doomed packs based on tap voltages, or even on stick voltages. Tiny voltage differences can mean a pack that...
  17. P1449

    Problems and Troubleshooting
    I haven't been able to hone-in on what exactly different UDD voltages - max depth and max rebound - mean in terms of condition. In general, though, high rebound is worse than low, if not for anything substantial then simply because it suggests the UDD wasn't thorough enough and/or in your case...
  18. P1449

    Problems and Troubleshooting
    You have to remove the shorts when you measure voltage at the taps, even if you're measuring voltage on the taps that aren't shorted. I don't quite understand why, but I think having the short in place moves the negative terminal of the first tap you're actually trying to measure to the end of...
  19. Polyurethane Engine Mounts

    Modifications and Technical Issues
    Same brand/part number as what I used. Reading my older posts, I wrote that the gap between inserts and housing was 3mm. If convenient, you should take an actual measurement of the housing hole in your OEM mount and your new DIY mount, and outside diameter of your inserts with the 'tube'...
  20. Polyurethane Engine Mounts

    Modifications and Technical Issues
    That's pretty cool, interesting. I wonder if it will hold up... What material did you use, and is it solid? I would have expected at least a mm of play between insert and housing. But, it's possible the tolerance for the bumpstops aren't all that precise - I saw a slight difference in diameter...
