[Gmecm] Anybody got a $4D VIN"Z" BIN available?

Jay...
 
not the only one confused.
I got the PN for the ECM off DynamicEFI (RBob's site) webpage.
He lists one ECM that has compatibility by pin for the 88-90 Camaro with a  
4.3L V, which I traced through GMECM files to a "Z" code 4.3L TBI that has a 
$4D  strategy.
So something is lost in translation.  Maybe there isn't a 1228063 with  a 
4.3L TBI in passenger cars (could care less if its a Camaro/Firebird).
 
Friend has a 230CID 6 cylinder, and I figure a 4.3L TBI is a good code  
calibration to start with IF it runs a MAT sensor (the $42 SW 1227747 doesn't  have 
one)
 
Want to actually use a 1228746 ECM in application, but I realize that the  SW 
in ROM is different between $4D and $61 (the 8746 code).  I think the  
1228063 doesn't make use of knock ESC.
 
So I guess what I am looking for is a 4.3L V6 TBI cal that can be compared  
to a 5.0L TBI cal from a 1228746 as a starting point.  One that uses a MAT  
sensor.
 
Any suggestions out there?

Hi there!

I'm a bit confused, so  please bear with me.

That cal ID / ECM is the 4.3V6 from Astro or  fullsize trucks, as far as 
I can tell.  4.3V6 TBI "Z" S-series of that  year used the 1228062 ECM 
and a different cal ID.  I'm not sure why GM  did that for essentially 
the same engine /  transmission.

Camaro/Firebird V6 of that vintage is a 2.8V6 MPI car --  different 
displacement, and different engine family (V6/60 F-car with DIS,  versus 
V6/90 truck with distributor).  The F-car of this vintage also  has a MAF 
sensor, so the fueling strategy is different from the 4.3V6  TBI.

So, which one are you after?  Or, maybe a better question, what  EFI 
system are you using and what are you installing it on?
