Choosing a new ECU

I have another thread here about improving engine performance - thank you all for your contributions. I have a new question about the next step. In addition to improving engine performance, I want to install an automatic transmission (that is most of the reason for needing more performance). If I want to break the limitations of the present ECU, I will have to buy another one. If I put a E4OD or a 4R100 in, I will need to install some kind of electronic device to help the engine "talk" to the transmission. If I am buying a new ECU, can I find an ECU that will also do that function, i.e. communicate with the transmission as well as controlling the engine, so that I don't have to buy two devices?

Stinger Performance Pimpxshift is what you are looking for. A few folks on this forum are using their products.

Thank you! Does that work with the ECU or can it replace it?

It replace a factory ECU that would control both engine and trans.

For 900 or so you can get a PimpX that runs the engine & 400 more you can get a PimpXshift that'll control a trans. (at least it was)

Made of 100% new components except for the case it comes in.

And that's going to be close to market standard for any tunable control only system.

As stated previously any aftermarket controller that can handle the engine and electronic transmission is not cheap. Price just a transmission controller for comparison.

Staying factory is cheaper but does limit the HP/TQ goals and custom transmission shifting.
