HOW TO USE THE WIRE TESTER

E4E-Z Ethanol Controller - How to use the wire tester

The wire tester consists of a body with two pins attached, along with two green LED's on both sides.

The wire tester is used to make sure that the injector plugs are plugged in correctly, so that the power wire is connected to the power and not the signal wire.

 

Step 1 :  To use the wire tester, start the engine.

Step 2 :  Unplug ONE injector.

Step 3 :  Take the injector plug that is connected to the stock ECU and place the wire tester into the plug's two-pin holes.

Step 4 :  Check which side of the wire tester's LED's are flickering.

 

The side on which the green LED is flickering is the power wire/connection.

GUIDELINE FOR MANUAL FUEL ADJUST

You need the optional Up/Down switches, and if possible

 

  • A display or
  • A PC with RS232 communication and the communication harness


These are some guidelines for various tank mixtures:

 

Undiluted Fuel: ZERO fuel addition  
Unknown mixture: Light load, cruising: 12-18%
  Heavy load: 20-28%
Undiluted E85: Light load, cruising: 15-24%
  Heavy load: 24-30%

OPTIONAL DISPLAY INSTALLATION AND OPERATION

The display wiring and operation is a little crazy.

E4E-Z Ethanol Controller - Optional Display Wiring

The unit can display the following items. One can be selected by shorting the ‘select wire’ (pin 2) to +12 Volts momentarily.

 

Fuel addition Fuel Added
Injector Utilization In percent. At 100% you are running out of fuel!
Narrow NAFRIN The AFR reading from the NAFRIN input
Wide WAFR The AFR reading from a BOSCH LSU-4 probe
Engine Temperature The temperature as measured
Fuel addition This is the total of fuel added
Cold compensation Cold compensation in percent
ECU injection The ECU injection length in Milliseconds

 

 

FUEL ADDITION

 

This is the fuel addition from the manual adjust or the automatic adjustment. The reading is in percent. If you are checking the injector open times, then you will notice that the injector ‘sluggish’ open time is recognized.

 

 

INJECTOR UTILIZATION

 

This is a very important measurement. It describes the duty cycle of the injectors. At 100% you can’t add more fuel because the injectors are constantly on. The engine will run LEAN at this point. This can happen only at full power and high RPM. The engine may be damaged if you are operating at 100% for any length of time.

 

 

NARROW BAND AFR

 

This is the AFR as measured on the NAFRIN input. A ZERO indicates that the input is not recognized.

 

 

WIDE BAND AFR

 

This is the wide band AFR reading from the BOSCH LSU-4 probe connected to the NAFRIN and the WAFRIN input pins. A ZERO indicates that the input is not recognized. The unit checks the NAFRIN input first, and if it is OK will ignore the WAFRIN.

 

 

ENGINE TEMPERATURE

 

This is the engine temperature reading from the optional probe. A disconnected or malfunctioning probe will be displayed in the software as red and will read 010°C

 

 

FUEL ADDITION (TOTAL)

 

This is the total amount of fuel added in percent. It includes the cold start enrichment.

 

 

COLD START ENRICHMENT

 

This is the cold start enrichment fuel added to the injection in percent.

 

 

ECU INJECTION, MILLISECONDS

 

This is the ECU injection length in milliseconds.
