Two quick questions that I would appreciate some enlightnenment on...

1. It seems like my IMA battery goes through a "programmed discharge" a few times per tank where it will discharge for no reason to about three bars and then slowly climb back up the charge bars. What causes this? My '00 has 140K miles on it now. Is my battery on its way south?

2. When I am on the brakes approaching a stop and I hit a bump in the road the car suddenly surges forward for an instant. This is while my foot is on the brake. What causes this bump acceleration?

Thanks much!

Its called a recal (short for recalibration of the IMA battery SoC). Search the forum and check the I.C. encyclopedia

Sounds like ABS operation and brake modulation. The Insight is known to have a "hyper" sensitive ABS reaction in your stated conditions.

HTH!

I agree with the ABS issue. I notice this all the time if I hit any kind of bump or pothole while braking.

Just wondering if the autocross guys are bypassing the ABS when they run on the track? It seems like the ABS would be a big set back and maybe even dangerous.

My Recal's most often occur if my insight has sat undriven for 2 or more days, especially in the hot Arizona sun. Then I get into any kind of stop and go with lots of IMA, the forced recal is as guaranteed as taxes! :evil:

Tracks are relatively smooth so I don't get any bump induced ABS kicking in. And i'm only on the brakes for less then 1 or 2 seconds at a time. If you are noticing the ABS engaging on wet or dry pavement under normal use on the street and it was not bump induced, replace your tires with better ones.
In snow and ice conditions I disable my ABS by removing the fuse, it allows my winter tires to work at their full potential.
Don't do this unless you have proper training and experience driving without ABS on snow and ice.
