1990 tracker -no start FI fuse?

[fixkick]

Thanks for the reply Fixkick, Without question, your knowledge on this subject is far superior to mine. Just looking at this with new eyes. Here is a bit of background - I proposed the question of replacing the 89/90 Suzuki sidekick /tracker ecu with a (yet TBD) similar application GM ecu to a gentleman at Dynamic FI http://www.dynamicefi.com/  . and/or  https://affordable-fuel-injection.com/?g...8oQAvD_BwE The question was rather general as equal to the reply.  The purpose of the question: Those, like myself, that have limited funds for fixing our rigs have (had) the idea of the rig being a “budget off road rig”.  This goes out the door when we are spending hundreds of dollars on the ECU alone. Combine that with the ever decreasing numbers of ecu’s that fit this application (as you pointed out) the hunt becomes just that a hunt – never a found! – no joy there. I also want something reliable -, As I noted in my OP the truck has been incredibly reliable, then it just quite - while idling in the garage. I got to thinking, what if this happened 2 weeks prior while I was out scouting sites 30 miles from cell service? My old carb/point dist. relic could always get going somehow but ecu fail with no prior signs is a nervous thought. The truck is a brick without the ECU. My thought was, IF a GM (or ford or Chrysler /honda –whatever) ecu from some yet TBD  POPULAR model vehicle could be adapted to work in the tracker/sidekick it would be a sunny day in the PNW! Imagine being able to visit most any junk yard and finding an ecu that would work in the truck. Maybe a pin swap here or there and a couple sensors from same donor or at least readily  available to purchase new on the cheap –whatta great thought  hence my inquiry at the forementioned websites. Living in KALIFONIA I am likely a bit more concerned about having a working ecu than others. We still must pass smog inspection on cars 1976 and newer here.  Luckily the 89/90 vintage rigs are inspected only visually for smog devices, timing checked and run on a dyno with a sniffer. So if ecu is working clean –all GTG! OBD 2 not the same song here. The shame of living in
CA is a subject for another forum………
I’d appreciate your thoughts on pirating an ECU from another vehicle brand and adapting it to work on the 89/90 model specifically. Id also like to learn of any aftermarket ecu that would / may fill the void of the ever decreasing supply and increasing cost of an OE ecu.

find a carb put it on and run it.
you already have spark for free. (mr.dizzy does that with own VR sensor and own ignitor and advance mech)

find carb and tune it.
no lack of carbs, even off motorcycles.

but carb kits are not easy to find .

now lets talk alien ECU, will what would that be, answer toyota,  over 40 million 1.6 made called  Toy Corolla, more of these made than any car on earth
read that as endless new and used parts, find one and adapt  it.
the hard part (besides lots of wiring mods) is spark if the ECU can not control spark it will go mad,  spark and fuel are 3D maps in the firmware,
if the MAP (array of data means) is not indexed correctly it fails.  see what I mean?  if not study tuning a MegaSquirt ECU.

they have custom tuning on most of these now, done by hackers, nobody hacks G16B suz.
lots do TOY. huge it is.
I will look in my manuals, 1985 to 1999 for something that can work 1.6L. (or near)  for sure all sensors need to be changed, and spark issues and injector, are not the same.   The best ECU is MAP sensor based, not MAF.  MAP is far more easy. like yours is.

more later.
you need to use 1.6L so the data 3d maps (tuning) will work in firmware or if not have to re tune it. your self. (and burn EPROMS to get there)
Lets start year 1985, toyota were some of the first Asian cars with EFI. (digital not analog like 1978 VW had)
