Aftermarket Automatic Transmission Control

One of the most overlooked are of aftermarket programmable electronic fuel injection systems is the ability to control electronically controlled automatic transmissions.

The problem becomes, that if you install an aftermarket electronic fuel injection system on a vehicle that has an electronically controlled automatic transmission, you will generally have to piggyback it over the original ECU so that the original ECU can control the auto trans.

Luckily there have been huge advances in aftermarket electronic fuel injection systems, and you are able to install a fuel injection system that can supply an engine of up to 8 cylinders with sequential injection and ignition control, and at the same time control many electronically controlled automatic transmissions.

This is achieved by using many configurable auxiliary inputs and outputs to switch the gear selection and line pressure solenoids withing the transmission.

Now, the great thing here is that if you thought your transmission was a bit of a slush-box, and you want your shifts to be a bit (or a lot) more solid, you program the electronic fuel injection unit to do this. You can even have it switch hard when you want, and softer when you want.

There are so many possibilities now, with the massive flexibility of some electronic fuel injection systems.
