The MicroTech LT-9c incorporates several new and exciting features while still retaining the race proven reliability and simplicity MicroTech are world famous for, all with an outstanding price tag.

Each Kit includes:
X4 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, dash display, coils, etc are available as an upgrade option.

Each LT-9C 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-9C is capable of controlling sequential injection on 4 cylinder engines as well as 2 rotor Mazda rotary engines (2 rotor 12A, 13B, 13BT, 13B RE 13B-REW)
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 X4 Ignition/Igniter box upgrade:
The X4 is an optional ignition enhancement module that adds remote igniters into the X4, rather than having to use coils with built-in igniters. The X4 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.
