Bit of a change from NSX but nice to see different models....

Got hold of the 2pin style IG coils over Rockauto for the future service for one owner.

From time to time, it got on back order and on this occasion, I think they only had one in stock and remaining five came from somewhere else.

As fa as I can tell, it's the same as the OEM one in a different box.

Based on previous observation, possibly, the B-rank due to markings around the connector area.

The vent hole position is for the rear bank so it's marked as 'RR' but owner is happy to use them even at the front as it's very rare for the moisture to get at that side.

I need better function generator….

The square waveform edge is not sharp enough but that was expected when building cheap DIY circuit board….

Even after re-calibrating the speedo, there is still about 3mph difference at high speed range and yes, I'm aware of using both adjusters for this.

Please don't delay the A/C service.

The more you wait, the more it will cost.

The owner had the system re-charged several times but if you had to do it so often, you already have big leakage.

Considering the size of the drier/receiver on our NSX, you should be fine for years before requiring another re-charge.

For your reference, until I had to replace my evaporator on my NSX in 2016, I only re-charged the system once over the 22 years.

The owner was told that there was no leakage detected when he took the car for a/c inspection.

Without the dedicated gauge for leak detection, one won't notice it unless you test the system for much longer period.
