Diablosport Forums

Hello, I own a 2005 Dodge Magnum RT. I understand that this is one of the early models (build in late 04). I have done some mods to the car and I plan to do some more. One of the tools I purchased to tweak the engine's performance is a Superchips Flashpaq. I have been quite happy with it except for one thing; I have not been able to change transmission settings. I cannot adjust the shift firmness and set it to paddle hold mode (stay in the gear I select, no matter the rpm or the throttle position, until I choose to change the gear). It is simple. I can't stand automatics and I love manuals but this car is not offered with a manual, so I had to buy the autostick setup. The rev limiter can only be partially adjusted and the torque management cannot be modified.

Anyway, I was told by Super chips that the reason for this is that the TCM and ECM software versions installed in my car cannot be modified by the Flashpaq. My dealer tells me that those are the most current versions and that they cannot be updated on his end, so I am stuck. Super chips can do nothing, the dealer can do nothing, and I hate how out of control my transmission is...

I am attaching two photos showing the ECM and TCM numbers.

So finally, here is the question for you: I am willing to purchase a Diablo Predator if someone can tell me that this programmer will have no problems dealing with my car. Can someone tell me if this is the case?

Thank you

Ours will give you all the trans adjustments EXCEPT the autostick hold option, the TCM/ECM combination will not allow it.
What i would recommend is go on the LX forum and get a hold of Mr Incredible and he can sell you a TCM that will have support for the autostick option, if you do that the Predator will allow you to disable it.
