Forget the wishful thinking you've heard spewing out of your radio about fuel injected
Stingrays, 409s, and little deuce coupes - the artists of the songs below knew
where it was really
These EFI maps are for the Holley Commander 950 ECU. They were generated on my 440 using the 900cfm "350-500hp" TBI system (p/n 950-21S, four 85lb@21psi injectors). I am providing them in case someone else out there is using this EFI system on their big block Mopar - hopefully it will make the process a bit easier for you than it was for me. If your engine is anything like mine, using one of these as a base map to begin tuning should be a whole lot better than the generic Chevy ones provided by Holley. If you have found these useful, please let me know! Although it is definitely not a requirement, if these maps help you out and you feel like giving something back, I certainly wouldn't be beneath accepting a PayPal
donation to firstname.lastname@example.org to help offset my time and dyno tuning expenses!
