It appears the modules in the center tend to get hotter and so degrade faster. Apart from shuffling modules, what can be done to mitigate this? Maybe some kind of low-profile heatsink? Additional venting? Thinking I might run a duct from one of the AC vents to the HV cooling intake.
I've heard of others running ducting before, and there might've even been a product offered for such. Pretty sure it came from underneath the passengers seat and went into the HV fan duct. For extra cooling I run Torque with a PID that sets the fan to level "6"
Jeff at prolong has floated the idea (and was soliciting feedback) about developing a user controllable HV fan device so the driver could control fan speeds and durations.
Torque is an app for the android phone. Also bought a cheap bluetooth OBD2 adapter online for $3 including shipping. If you buy a more expensive model it may come with an auto power down feature which prevents it from draining your 12v battery. @usbseawolf2000 's thread on custom PIDs :Gen2 Prius: Custom PIDs for Torque (Android App) with formulas | PriusChat
