Like the title said, plan on tuning a cummins with a splitter harness for dual cp3s and 150% overs.. Where should I be looking to get the cp3s working? Add to regulator vs flow? Working with efi live software..
Thanks!
You can try doubling the current curve for the FCA. I'll warn you right now that some ECM's do no appreciate this apparatus. The circuit was not designed to carry that amp load and I've seen very strange things happen on occasion when using the splitter harness. My advice would be to get 'Fish Tuning's' module instead. ymmv

Ok thats good to know! I'll advise him to get the controller. Thanks for the response
I had the y harness in the past...i did around 1.7x the current table...but now i change it to a fish controller since y harness draw to much current and can burn ecm overtime
Good to know! He ended up just ordering a fish controller.. Its cheaper and less headache than a burnt ecm
