There are new software updates out for the 2005 Honda Accord Hybrid. I got one for the ECU/IMA and another for the transmission. Shifting and clutch performance is a lot less stupid than the original software. In fact, it could be worthy of a K car now. Original: Tire squealing lurch waking from auto-stop, dangerous forward lurch while braking (IMA shutdown), looses speed when gas pedal is depressed quickly, lug then lurch during light acceleration, bug that could fry the IMA system when a generic diagnostics computer is used. Recall: Fixes IMA bug, lurch waking from auto-stop, lug then lurch, and the dangerous forward lurch while braking. Adds lag when accelerating lightly, limits RPM for no reason, and the torque converter twitches on slight inclines. Latest: Fixes lag, slowdown when gas pedal is depressed quickly, and mostly fixes the torque converter twitching. Not sure if it fixed the RPM limiting.
