The 280Z was infamous in EMI/Ham circles for the total lack of shielding and bypassing on the CPU.
?
A fellow engineer had one and thunder storms were enough to cause it to run rough.
Every lightning strike within 100 miles caused a miss.
We wrapped the CPU in tinfoil (honest to God tinfoil with small holes punched in for ventalation) soldered a ground wire to it and applied 1000pf feed through capacitors on an 1" X 1" by 1 foot alunimum L strip for all the power, data and fuel injection lines.
The CPU only monitoried engine speed, incoming air temp, and crank position.?
It didn't monitor throttle so I was never sure how it accelerated.?
It was one of the few production cars that could beat a Honda CB-350 or 450 off the line for 50 to 100 feet.
Many cars would catch up with a Honda CB-x but damn few could beat you for that first 50 feet.
The 289Z had an obscene acceleration to mass ratio, was made from thin metal and didn't do well in even slow speed crashes.?The fellow engineer lost control on a rain wet road at 30ish MPH, the car looked like it'd been through a crusher.

Datson reduced weight everywhere they could including the frame,

Back then I ran 200w on ham HF and could shut down many cars at stop lights by keying down.
Audis were the worst. My 2W 2m (144MHz) walkie talkie would shut them down 100 feet away.
