Early EDM non-cat 4A-GE 16v Bluetop Fails emissions (high co)

[Rascal21]

Fuel pump is fine, it can do around 5,5-6 bars.
-- Installed Tomei FPR with gauge AFTER fuel filter and still getting good pressure.

I did test as above yes:
--Connected wire to W-pin on ECU as per Early 4A-GE pinout diagram, shorted diagnostics plug, ignition on, + test lamp on W-wire and - test lamp on earth, nothing.
--Changed ECU, nothing.
--Checked harness again, nothing (bad).

Tested lamp on battery, lights up no problem.
--Try different lamp, nothing, test on battery lights up no problem.

Start car, warm up, drive around and hoon no problems no hiccups, no limp no ignition problem no nothing, runs like an absolute champ through all revs, hill climbs in 5th gear with 3.9 final better than large diesel cars, zero problems, good fuel economy.

--Opened both ECU`s, both of which were tested with zero problems before sent to me.
>No blown capacitors, no mis-colorations on PCB, nothing, nice healthy ECU`s by the looks of them and both runs the engine like absolute champs.
--Try test lamp again, nothing.
--Switch ECU again and try test lamp again, nothing.

Start engine on first crank, 2000rpm cold idle and down to 800rpm factory-spec idle, pull out of the driveway and again run like a champ, SILK smooth with no issues.

--Put engine in diagnostics mode with engine running and idle goes down as per factory manual to 700rpm (so diagnostics mode works), put timing light and find that base timing (10 BTDC) is spot on.

--Try test lamp with engine idling in diagnostics mode, nothing.

Sigh..
