    Is 21 csp5 available or in the works?

    Not available, don't know if it's in the works or not. You can probably use the 2019 CSP OS just fine, parameter wise there is virtually no difference between the 2019, 2020 and 2021.

    Actually depends on which calibration you got for your 2021, some there is almost no difference, others there there are some differences

    Using a different OS on the 2019-2021 trucks is no different then using different OS

    Some reason 90% of what I posted didn’t get posted. To finish it, it’s no different than using different OS’s on the 2013-2018 trucks, it can be done every day all day long without issues. The thing to watch out for is if your 2021 from the factory is the cp3 or CP4 truck. If it’s the CP4, no problem at all, if it’s the cp3, you’ll want to change the FCA current to flow table and a few other minor things. There is actually very little difference between the 2021 cp3 and the 2019 CP4.

    That makes sence. I figured it was an ecm architecture/security thing keeping it from being released like the 2022s. I guess I'll give it a shot with a 2020 base file with cp3 tables

    Has nothing to do with security/architecture of the ECM and everything to do with EFILive writing the coding for CSP on the 2021 calibration. The only 2020 calibration that CSP support is 52200300, which if I’m not mistaken is a CP4 calibration, not a CP3 calibration.

    There also some single element parameters that would need to be changed as well that EFILive doesn’t have mapped, otherwise your flow through the injector pump will be restricted.

    Would you happen to have the stock file for a 2020 Ram 3500 with Aisin and the recall CP3 pump upgrade? Unfortunately I do not have the stock cal information. Thank you!
