Would the atlas 40 tune work well on this? Has it been used on a vt365? How would it interface with the MP8?

Thanks,

Jeff,

Welcome!

To answer your question... Yes. The FICM tuning works great on the VT365 and provides solid improvements to performance, throttle response, and economy. We see the same gains on the VT engines as we do on the standard Ford 6.0L applications.

I do not have an answer as to how it will work with the TS MP8 as I'm not certain what the MP8 affects in the engine controls. If you could maybe provide some insight as to what it connects to, I might be able to make a semi-educated guess as to what it's doing. In other words, does it connect to the OBD connector, the engine harness, or both? And if connected to the engine harness, which connectors or wires is it connected to?

We also currently are offering ECM tuning for those trucks, if that's something that interests you. Feel free to give us a shout if you'd like some more information.

Take care.
