The PI as in the original TR5 and 6 was a 'dirty' injection system. It
probably won't burn as clean as the carbs.......
I would just like to clarify this point. The Lucas PI runs a little rich
at idle due to only have a mechnical advance in the distributor. Once at
speed, the PI system leans out quite nicely.
1970 TR6 PI
would run a liof course typical carbs
with 50,000+ miles are so whacked out that they don't run clean either. The
standard tricks to pass are to retard the timing until it barely runs, and
put in a can of e-check cheater. The stuff works.
My understanding is the car must pass to the standards set for the year of
the engine installed, or the year of the car, whichever is more
Most stations won't care if you are injected or not, as long as you pass.
