I didn't believe it either until I learned more and started trying to
calibrate my own system but:
Unlike the Stromberg carb, the Lucas PI system lacks temperature/altitude
compensation. Cars sold in the USA had to meet emissions requirements
whether they were destined for Alaska, or Arizona- Denver or Death Valley.
I always thought the real story was that the USA dealers were luddites who
didn't want it. Knowing what I know now, there's NO WAY it would have passed!
Here in Chicago my PI equipped TR6 runs lean in winter and rich in
summer... unless I make appropriate adjustments. The Lucas system is
technically "sequential multi-port injection", but this simple open loop
mechanical system is primitive compared to a modern electronic system.
I love it. ;{)
