I'm not exactly following what you are saying.
The X3Z is the Cobra EEC.
Codes should be able to be outputted in any event.

They should be able to pull codes regardless. Looking at your parts numbers, you have an X3Z, aka 93 Cobra processor. You will have to stay with the X3Z, as it is calibrated for your 24# injectors (unless you swap mass air meters).

It will run a lot rich if you do that. You could throw it in there at the dealership and not start it, just turn the switch to "on" and see if they can pull codes that way. If they can, it should read clean, but at least then you'll know they can read it, and then you can get a new X3Z.

I'm just saying that replacing your X3z with an a9l will not work unless you either:

• replace 24# injectors with 19# injectors
• replace mass air meter with one calibrated for 24# injectors.

I'm not sure which post you are talking about - is it the one about "switching to carb from efi"? If so, I haven't really gotten into that thread, since it was so long before I even saw it. It was at 3+ pages when I saw it the first time.

I'll try to check it out when I get a chance.
