Since 32 and 6E code are both for MAF systems used in the same vehicles, and it seems that the only major difference in the 6E is the absence of the cold start injector, would it be possible to set up an EPROM using 6E code, install it the Calpack that I have from the 1986 'vette, and operate my system without the 9th injector, or would there be conflicts with the memcal? I know that the ECMs are the same part number ('7165), but I do not know of the other conflicts which might exist. It is my understanding that the different codes and there interpretations are contained in the EPROM, and outside components are not affected by the different formats. It seems more that the EPROM code tends to be designed around the components it affects. Is this generally correct? Could I go to the more common (and apparently easier to work with) 6E format, and retain my other components?

 

That's what I did, although I have an '87 Camaro IROC-Z. It has (but I disabled) the ninth injector and MAF sensor and uses the '165 ECM, and I had no problems using the 6E code. I didn't notice anything better until I started tweaking it, but (as others have said) it is supported better than the 32B code. So, go ahead and use the 6E code w/out any worries.
