Proper initial calibration GM performance ZZ4

[cantdrive55]

hello EFI guru's

I have a question regarding the initial programing of my proflo2 model 35000

The motor setup is:

GM Performance ZZ4 crate engine
2 1/2" Ram Horn exhaust manifolds by Speedway
2 1/2" Pypes "race pro" exhaust
Mallory distributor for proflow
"E" type coil
dual O2 sensors regular band edelbrock


Which base line firmware should I start with during the initial setup?

Thanks

Frank

You can use either the 3512 or 3514 calibration files. Both should get you up and running. The 3514 is set up for a little bigger cam and might be a little lean in the low end if your cam is under 230 or so deg of intake duration at 0.050".
