1990 Geo Tracker 4x4 Manual ECU 60A31 Repair
#15
yes, if the , plus driver is dead.
and the yellow driver is good.

the ecu sends crude inaccurate pluses to the hot wired injector and it does fire and run
but runs like crap.

i could make a ECU from scratch with simple parts, that run better.
called aN alpha injection system , like some race cars use.

it uses RPM and TPS as inputs and runs rich. 12;1 AFR is max power . so...
it computes air flows, of just 2 sensors
just because something runs, is not magic, or amazing, what matters is runs right.
on your car, the ECU makes no spark
so we can slap a harley CV carb on it and make it run great.
or any carb for that matter, run.
spark,in the Dizzy good.
