Stock File Needed: 2020 Ram 3500 with Aisin and factory CP3 pump upgrade

[slimmons2009]

Would anyone 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!

Better off using a 2021 CP3 calibration as the 2019 and 2020 cp3 calibrations aren’t useable with EFILive.

Would you happen to have that file?

So out of curiosity if the 19-21 trucks have the CP3 recall done and are currently tuned with "Old" cp4 software they will require a revision for new pump? Didn't know if that was just a OEM stock truck thing.

There is around 40 parameter differences between the cp4 calibrations and the cp3 calibrations that cover more than just the FCA current to flow, things like max flow limit, current limits, PWM, feed forward constants, gains, flow constants.

Oh okay well good to know.
