G60 ECU pin 23 - Voltage HELP - Diagrams link

[Trakx 0]

From what i've read corrado G60 till 07/90 has ecu pin 23, which is my case. Was cheking the electrics (from viewtopic.php?f=1&t=29418&st=0&sk=t&sd=a&hilit=pin+13+23&start=585 ) and everything ckecks ok 12.3 V with the exception of 13+23 = 11.2 V !!??

 

What could be wrong ?

 

and some other questions:

 

1- Are ECU interchangeable (before 07/90 after) ?

 

2- Will any chip work? (never heard of diferent chips for diferent ecus (except California models, i think are diferent)

 

3- Whats pin 23 for?

 

4- Can one "convert" this ecu loom to newer one without pin 23?

 

Also found: "23 auxiliary control Digifantr elais (only with STG" B" , starting from CP freely)

24 with STG" B" freely, starting from CP on Leerklemme2 with Digifant relais sockel "

1- Are ECU interchangeable (before 07/90 after) ? Should be yes.

 

2- Will any chip work? (never heard of diferent chips for diferent ecus (except California models, i think are diferent) There are several different chips, the later the better and all work with all G60s except for the ones with throttle potentiometers.

 

3- Whats pin 23 for? Don't know, I am at work so cant check the wiring diagram right now.

 

4- Can one "convert" this ecu loom to newer one without pin 23?

Pin 23 is still there on later looms it just isnt used by the ECU.

News:

 

It seems that ecus are interchangeable, as written by Yandards.

 

I've not yet come to a conclusion on the PIN 23. It seems to be redundant and so put aside on newer ecus. Still figuring it out with haynes and Ecu board layout.

 

But i also found out that newer ecus have PIN 24. This is "hall out", basically Tachometer signal to cluster. I think, in this case, these are the ecus to be used on double digital cluster G60. I'm not sure if old ecus had this feature but i think soo.

 

About ecu looms:

My Corrado G60 has the Pin 20 (mil out) and Pin 23 but not Pin 24.

From the info i could gather it seems that newer G60 don

pin 25 coil

pin 24 not used on early cars, tach out to clocks on late cars like mine.

pin 23 isv.

Unless theres even more diferences.. PIN 22 is ISV not 23

one signal(22),one return(23) apparently.

You are right :) . Just cheked Bentley diagrams.

Just to close this subject.

 

Pin 23 is redundant.

Any G60 ECU will work on any G60 engine.
