Standalone ECUs
If you’re considering utilizing a factory intake, injectors, and cable-operated throttle body, with a 4L60, 4L65, 4L70, or 4L80 GM transmission, FiTech’s Ultimate LS standalone self-learning ECU with transmission control will get your engine ready for optimal performance. This self-learning Ultimate LS ECU is the best solution for a standalone LS swap and replaces the OEM computer and harness. This kit is dedicated to LS or similar engines with crank and cam sensors. The Ultimate LS standalone kit will self-learn to most cam swaps. Usually, only very large cam grinds will require additional tuning in the system. Easily tuned for even the most novice tuner, this kit includes a touch-screen controller for easy setup and configuration. The electronic transmission control is used when operating a GM electronically controlled automatic transmission. The Ultimate LS ECU has the ability to control the shift point, shift firmness, when to downshift properly, and all other features involved when controlling the transmission. This feature is suitable for 4L60, 4L65, 4L80 or 4L85 GM transmissions. If using transmission control connect the two sides of the trans connector to the sub-harness and connect this to the connector on the transmission. Once connected to the transmission you are ready. If not using transmission control leave the connectors untouched.
Application:
Contains a 3 BAR MAP sensor for power adder applications that supports up to 30 PSI of boost.

- Output driver for most speedometers.
- Compatible with car and truck coils.
- On-the-fly programmable target AFR and timing (if desired).
- Fuel pump relay output.
- Custom wire harness (uses factory coil pack sub harness).
- Knock sensor control.
Specifications:
The description says it’s for stock injectors. Does this just reference the pigtail for the harness? I imagine if it’s a three bar map built for running boost it will accept Changing injector data up to 80 pound injectors?
The product picture for this kit shows two o2 sensors and exhaust bungs. I don't see it mentioned anywhere in the description. Does this kit include two of each as shown in the picture?
Will this controller control a 4L60 transmission if it is 4 wheel drive?
Will this work with 94 and earlier 4L60E transmissions with the 12 pin connector?
Building a 2003 ss silverado wired trottlebody what do I need to convert where this system will work or do I need to go different route
Is this a viable replacement for the OEM controller, as used in a Vortech Lq4,Lq9 install?
which style injector connectors are on the harness? And will I still need to hit the dyno to get the max out of it?
Will it work with drive by wire throttle body
