lost my long post... dang.
ok, lots of words, (complex topic, a/t is , as is ECU) double trouble.
first off that list of ECU is junk, sorry, but my list is USA Suzuki real. and complete
the 58 means MPI, 56 means TBI so....
58B00 (last digit is revision levels, or smog tweaks) B01 is version 2 of this ecu,
cardone sell sells it rebuilt for $400 , used no ebay, are $50 to $100, 99% scalpers there. so..... YMMV
look gain, type ecu in my search box, and land
http://www.fixkick.com/ECU/ECU.html#EPC
then pick your year
and get...... this
http://www.fixkick.com/ECU/EPC-ECU96-98/...9-95NA.pdf
see last page, and YOUR ecu, in fact see all ECU in NORTH AMERICA.
the newer cars are on my same 1st link above 1996 up.
the red words are my crib notes. showing the odd suzuki coding.....
next the 4speed 03-72LE (A44DE) trans.
so why not do the tests? (its first not new transmissions)
1: stall fails cold. (and shifts late hot)
so you remove the top end of the cable, TV,
then you feel it, is spring 17 working, if not it will never shift right if jammed (by any means ,end to end)
if the spring works, i can feel the cam move say 1.5" of spring travel (cam) after slack taken up, sure.
then it may be ok in the box.
if it feels ok, then now drive with it unconnected.
no more, 10min delay (whatever, as 1.2seconds delay is max spec) then drive. it,
does it shift up nice, ?
yes/no?
ok so now there can be 2 issues, here. like all A/t
lack of engine power, will cause all A/T to shift late. what if there were 2 problems (pretty normal for 20 year old cars, right?)
what if the engine is weak.
so unplug the TCM at TCM or at side of box, left side. connnector.
drive in Low, then 2nd, then Drive(OD)
and reverse last
do all gears work?
do any slip?
does engine have full power in each gear?????
drive low, 2nd and D, shift like a m/t box, with 2nd missing, so 1st will need RPM wind out. say 3000 rpm or more. the cut the throttle and shift to 2nd.
repeat, and wind that out, load it up and shift to D (od is 4th)
see?
suzuki does not publish the command authority of the cam #20....
(that means I dont know what happens if it sticks 100% open..... seems losts more than shift points are effected, seems it causes low line pressure full time.
and effects cold start too....
fixing 20 year old cars is not easy
for sure not having a scan tool, makes engine EFI diagnosis a pure hell....
case in point, you scan it and you have 02 sensor dead, or worst stuck at 1v.
or LTFT long term fuel trim is at +40% and worst stuck there and out of control...... (a horrid lean engine)
the A/t can not hide a weak engine. so the engine end is first. for sure. and is listed as #1 in my FSM on , 4speed, pages..... and should be...
btw1:
if the engine is weak, disconnecting the TV cable on top of engine TB< will allow it to shift better. (lowers shift points ) it might lug engine though.....
i have 10 fsm books on Vitara's (sidekicks ) etc.
and one the SQ416 has the best 4speed chapters. im exporting them to PDF now.
chapter 7B1-13 to 36 pages.
