Lexus V8 Conversions

The Spitronics Engine Control Unit (ECU) is designed to be a cost effective replacement for Hi-tech fuel managements systems. It uses unique features found in Hi-tech systems, but it is still easy to install and program. It is designed with both the novice and professional installer in mind.

The Spitronics Engine Control Unit (ECU) is a South African developed and manufactured product and can be customized to suit dedicated engines and models. It is a reliable and compact system which is easy to mount in the driver's compartment. No external firing modules or converter boards are necessary.
 
The ECU is customized for specific applications and the installer does not have to pay for unnecessary wires or unused features. No separate firing modules and MAP sensors are needed. The ECU is delivered with the correct harness and equipment as well as software and maps to ease installation and setup. The software will also be calibrated to suit the sensors of a specific engine.
 
The Spitronics ECU unit comes in three models with dedicated harnesses to accommodate specific engine requirements:

• Standard
• Intermediate
• Advanced units

The units are designed to be small and compact and use the latest in high speed micro controllers assembled with surface mount technology.
 
Firing models are incorporated in the ECU and will reduce cost. Optional Analogue and Stepper idle control units can be used with all units.
 
The PC Tuning software is standard for all the Spitronics units. The specific ECU will blank out all tuning fields not applicable.
 
Other key features are variable charge times which is MAP dependant. The higher the manifold pressure, the stronger the spark.

Which Spitronics system do I need?

1. Standard ECU
Suitable for a single trigger (one pulse per spark) and batch fuelling with a single coil and rotor distributor like a Golf.
 
2. Intermediate ECU
For a complex trigger system like the crank gears or the dual pickup system for Toyota or Nissan distributors and still have one coil with rotor distributor, the Intermediate ECU is applicable which will do sequential fuelling.
 
3. Advance ECU
If it has a complex trigger system like the crank gears or the dual pickup system for Toyota or Nissan distributors and have coil packs or a coil per cylinder, then you must use the Advance ECU which will do sequential fuelling and wasted spark timing.
