e.g 1 CMK E5AE 9C485 CFi Fuel Injected M code Automatic transmission only 1985 5.0 2v Mustang or Capri
VECI does show the V REST for the CFi M codes between the Purge Valve and the Charcoal canister
e.g 2 CHB E5AE 9C48 4 bbl Carbed M code Manual Transmission only 1985 5.0 4v Mustang or Capri
On all other 4-bbl F codes (1983) M codes from 1984 to 1985, the system is quite different, and not the same as the CFi or 86 Port 5.0 EFI
Red car is the 86 EFi or later 5.0 Mustang
Live data. 1986 to 1990, no but people who do MAF conversions pick up the later DCL capable EECIV's, and they work.

EECIV you can no real live data (except maybe a few things). It has to be able to access the the data bus, but you can find a heap of 1991-1992 5.0 A9L's that have it and 5.8 box codes as well.On some vehicles there may be 10-12 PID lines available; other models can provide as many as 40+ PID lines. It's far easier and faster to diagnose faults with these newer systems that can transmit a data stream. Prior to these systems, you'd have to use a breakout box or backprobe circuits, which made testing much more time consuming. But now, with the advent of EEC-IV data stream display, it's a walk in the park.
By the early 1990s certain 5.0 and 5.8 Ford/Lincoln/Mercury models had sensor data streaming capability. The feature is technically called DCL (Data Communications Link), not just DTC's. These models have 2 additional data bus wires to the EEC-IV diagnostic connector.
But Live data is avaliable although its polling rate is low. PIDs (parameter IDs) were set up by Ford as OBD I (a 1991 and later California) standard.
Technically, most EEC-IV around 91 and later supports the live data stream without twEECer or Moats Quarter Horse.
with twEECer or Moats Q/H http://www.tweecer.com/ will plug in the J3 port and look at the data after the EEC filters it
with sneeciv http://www.racesystems.com/sneeciv/sneec.htm will give you data from between the harness and EEC
OTC 3211 opens up any PIDS, the EEC IV sensors and relays which are monitored via the old 007 breakout box.
