problem wiring injector gdi 3cyl

[bocia79]

hello. 

I've some problem to wiring error in my suzuki's 3 cyl engine (firing order 1-3-2)

reading instruction normally i need to connect like this

cyl1 1a 1+

cyl2 1b 1+

cyl3 2a 2+

with this configuration in injector testing are powered by this table:

inj test#1 -->cyl 1

inj test#2 --> nothing 

inj test#3 -->cyl 2

inj test#4 -->cyl 3

If I start engine with this configuration fire only cyl 1 and 3

and i have wiring fault 2A-2B active

 

If i connect by this table:

cyl1 1a 1+

cyl2 2b 2+

cyl3 2a 2+

 

in injector testing all works fine and in engine fire all cylinders, 

but i still have in red wiring fault 1a-1b and 2a-2b.

What's wrong ?

Thanks

Your firing order table is set wrong.

Hi Clint, my engine's right firing order is 132 and in my basemap is 132 (maybe I uploaded an older basemap version). 

If in masemap I put 123 fire only first cylinder.

I suspect there may be a firmware issue that causes the wiring fault error, I'm not sure if we have tested it on a 3 cyl before so it may be something that was never considered.  I will discuss with engineering next week.  Does it run ok apart from the error?

Thanks Adam. 

The engine run ok, only this wiring error and sometimes triggers error when engine stop.
