Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Testing the A/C CCU board using my NSX.

Went through all sorts of test scenarios including the Function & Operation check.
Testing in Mode 5 at the moment.

Fan control is now recovered and operates from Min to Max linearly.


Happy with the result so the board is ready to be returned to the Honda dealership.








While testing on my NSX, I felt that the air coming out from the vent was not as cold as yesterday.

Checked the gas level at the receiver window and sure enough, lots and lots of bubbles.
And on the garage floor, I saw this....


Looks like the hot weather on Wednesday accelerate the tiny crack at my evaporator.
About 3 years ago, I first noticed the issue as reported here and now it looks like it’s getting worse….


My 21 years old with about 150K miles compressor is not as quiet as some of the late NSX models that I test driven so it’s getting tired....

I have hair line crack at the defrost panel at the daylight sensor as well.

I hate taking the dashboard out in the cold weather but looks like I need to find some time this winter in order to work on my NSX replacing the evaporator, compressor and the defrost panel…..
Big task.....


For now, I’ll top up the gas to survive this summer.
