what makes you think THE G16a ENGINE is good? (just because it idles proves little) I've seen them do that, , with near flat cam lobes. (cam a train wreck)(but is undriveable)
Ever check compression, over 150PSI(10bar), wide open throttle)?
Flash codes 12. (means only wires not broken to sensors or shorted)
spark advance work correctly?. (using any automotive timing light ever made even my 1970 light works perfect still, I have 2, old and very modern) it will advance 30degrees or more (left of scale , huge)
you can NOT mix distributors. (ecu must match Distributors)
The ECU must have a MATCHING MAP and ECT. sensors, you can NOT mix them, and 10x that in EU... they have up to 7 TYPE engine classes there for G16 vitara. (unlike here we have 2)
you can not mix, most those parts presented!!! (that 56b70 only works with 1 distributor, and will NOT like SAMMI sensors,)
stick to the Samurai EFI , end to end, get that working, then play swap parts , 1 by 1 and learn that most won't work or many in your box are just bad or wrong parts.
all we really know here: (IIRC)
is what?, engine idles ok.
fuel pressure great. (tested)
and some kind of power loss, not CLEARLY stated.
we know it likes the ECT unplugged, but that trips limp-home , HIDING TRUE CAUSE of failure!!!
do you know what limphome does, well for one thing IT SIMULATES THE PART removed, and does so with CRUDE METHODS, horrid rich, and retard timing.. and no idle controls.
power loss is complex so needs clear statements .
I can't drive it ,
nor hear if misfire?
or smell the unburned fuel or its black smoke,during that event.
or see the spark tips turn black. or drip raw fuel. or other gross contamination to same.
I can not hear or feel the engine shake from misfire.
i can not feel the bog
I can not feel power, during wide open throttle , (normal or dead weak,)
but we do have lots of Franken-Sammi's here, lots.
The old sammi system may run the G16a , up to 80% power is my guess, or who knows? but will have good engine power. 300cc more flows. (I think the SAMMI map sensor can handle it, but that is theory (a 1 bar sensor)
when the SAMMI sees 0 bar vacuum (near ) at WOT, it uses fuel flows for 1300 cc not 1600 !, so will be lean, wide open throttle.! count on it!
This is why most the guys here, swap engine , harness and 100% of all G16a EFI parts and sensors, The whole package, saving most or all the grief you have now.
that is my best guess so far, not driving it.(or seeing it)
