N724CZ Cozy MK IV quick test flight.

I'd been getting red x's for CHT and EGT temp widgets. Also had recently gotten one of the displays repaired due to an internal short. Finally got to go for a quick test flight and only found one minor squawk which is the IFD540 is showing "No 429 data received". The gear overspeed warning is more to remind me to raise the gear after taking off (I've flown with the gear down at 150 KIAS without any issues). It takes 20 seconds to lower the gear with my current system, so barely enough time to raise and lower the gear when doing a lap around the pattern. Our pattern altitude is currently 1500' and will be changing to 1700' in October 24. We're near several Class D's and under a Class B.
