improved drivability after changing main relay?

I've followed the honda faq and changed my main relay after being let
down several times in parking lots
during the summer. It happened once last winter, too, I guess the same
reason, too much heat in the car.

Now I feel the care shifts more smoothly and at lower rpms.

Is it just my imagination? Could you guys shed some light?

thanks,

There's no connection. My car performs better and quieter when I wash
it. Maybe you topped up your cooling system too? That will change your
shift points if it was low.

My old man had a 1991 civic that had main relay issues. In the summer
when hot it would not start sometimes. Went all over trying to figure
the problem out because it was intermittent. Finally he called honda
dealer and they said main relay. He replaced it, no trouble ever
since!

 

theoretically possible that the relay was producing lots of electrical
noise that was feeding into the ecu's sensor circuits, but i don't
assign a high probability to that.

 

Thanks to all for clearing this!
