The Microtech LT-16C Standalone ECU the flagship model & is an ideal EFI engine management system for both the first time users or experienced tuners. For use with up to 16 cylinder piston engines or 4 rotor rotary engines. MicroTech is the preferred engine management system & are found on some of the fastest record holding cars around the world, with its ease of use being second to none. Often installed with the car up & running in one day.

Each Kit includes:
LT-16c ECU
X6 Ignition/Igniter Module (when selected from menu)
Programmed to work with factory Mazda Sensors & includes base map.
Flying Lead Wiring Harness w/ Loom (individually labeled)
Vacuum Hose
30A Fuel Pump Relay
Fuse Holder & fuse
Technical Manual Booklet w/ Installation diagram & set up operation instructions.
Hand Controller & coils are available separately or as an upgrade option.

Select Your Options From The Menu:
- MAP Sensor: 20psi, 30psi, 45psi or 60psi (select based on how much boost pressure you want to run)
- Application: Engine it's being used on.
- Add extras & upgrades: X4/X6 Igniter Box, Coils, Hand Set, Dash Display, etc.

Each LT-16C is pre-programmed with a base map to suit your engine, works with all your factory sensors & made to order for your specific application to greatly simplifying the installation and start up process. LT-16C is capable of controlling sequential injection on 4, 6 and 8 cylinder engines as well as 2, 3 and 4 rotor Mazda rotary engines (12A, 13B, 13BT, 13B RE, 13B-REW, 20B, 26B) and direct fire ignition for engines up to 8 cylinders or 4 rotors, or wasted spark ignition on engines up to 16 cylinders.
Once the unit is installed, simply turn the key & the car will start and run well enough to be driven to your closest tuning shop for final tuning. All LT's can be fined tuned either by the hand controller or by laptop making the system perfect for the 1st time tuner or the professional racer.

Microtech X6 Ignition/Igniter box upgrade:
The X6 is an optional ignition enhancement module that adds remote igniters into the X6, rather than having to use coils with built-in igniters. The X6 adds extra spark energy for higher HP application. If ordering your ECU with the X4 upgrade, be sure to use coils that do NOT have built-in igniters.. standard coils only. If ordering your ECU without the X4 upgrade, be sure to use coils WITH built-in igniters.
2 rotor & 3 rotor engines: Use the X6 Ignition/Igniter Module
4 rotor engine: Use (x2) X4 Ignition/Igniter Modules.
