I was interested in buying a 93 cobra computer, but do i have to run the cobra mass air meter or can I still use my C&L 73 mm with 24lbs calibration tube to go with the 24lbs injectors.

you need to get the appropriate calibration tube FOR the X3Z ECM.

^wouldnt the 24lb tube be right for that pcm then?

Why not get an a9l?

I currently am running an A9L pcm, but was thinking that it would be better to run a computer already programed for 24lbs injectors? I don't know much about the Pcm's capabilities.

the a9l is better than the xz3, stay with it

AdderMk2

no, because the X3Z and A9L run different maf transfers

You will need to change the sensor to match the ecu (X3Z), as the A9L used a different MAF sensor.
This is in addition to the tube change that was suggested by Mr. Adder...

I agree, running the X3Z which is already programmed for 24's would be a better option... IF that is the full extent of the modifications planned for the car.
Consider the long term plans as well....


I'd love to hear why you say this....
