Potential Tuner
6.4 intake manifold to 5.7 swap - cant activate SRV .
The intake swap went relatively smoothly. Extended Maf and IAT wiring harness, pre-pinned OEM PCM connector for SRV control, but cannot set rpm activation in hptuner. I know that there is an option to run SRV with an external controller, but I want to try control via PCM, as OEM .
below is a screenshot of my car 2021 challenger 5.7 and for comparison 2017 challenger 5.7 where SRV activation is possible. Both GPEC2A ECUs .
I know it's possible, but maybe only in earlier years, unfortunately mine is 2021
any ideas ??

Advanced Tuner
Look into a 2021 5.7 charger tune and it can be set.
Have you pssed the emission questionaire from HP ?
At this time I try to figure out the same. If I set SRV equipped to enabled then AlfaOBD can pass the test. But at driving there is no response from the SRV channel. Only 100% SRV percent changes at engine start to 79% ....thats it, no more change will happens by driving or revving.
I dont want to install another equipment to get in touch with it.
I do more test the next time.
