Now available are our complete LT5 / Manual control systems!

Our LT5 / Manual control systems are all built here in house on our LT5 engine station. The modules are programmed with our own custom calibration and test ran before shipping to ensure a properly functioning system is delivered to you and ready to install.

The control system includes:

Speartech standalone LT5 / Manual wiring harness
Programmed engine computer with base tune
Programmed auxiliary port injection and bypass valve controller
Wideband sensor (installs on passenger side)
In-line fuel pressure sensor
Fuel Pump Control Module (can omit if you place the order via the phone and you use an aftermarket fuel setup)
Electronic throttle pedal
MAF sensor with aluminum weld-on bung
Oxygen sensors (front pair)

Online purchase is for our default length harness. Default length harness is 42" from passenger side rear head and puts the modules under-the-dash. If you need a custom length harness or want to mount the modules elsewhere, you must call to order. 765-378-4908
