changes in ECU etc. in later years
In the early 85 thru 87 years, Distributor magnetic pickups had 4 distinct lobes. The 02 sensors in these cars had one wire.
From 88 to 89, the magnetic pickup inside the distributor had about ten or so points on it (lobes). The o2 sensors on these year models had 4 wires going to the O2 sensor.
While I have not experimented with changing older with newer distributors and ECU's . . . offhand I'd say that the variances described earlier are sufficient to keep the ECU's, Distributors, and O2 sensors matched up. You could move a complete set, forwards or backwards in year model groups. But I wouldn't mix them up.
By the way, that is a very nice looking Piece of Work you have in that ITB setup. Very Nice.
