could a fields vtec controller activate vtec? instead of using a switch.. could it control the fuel maps as well for when vtec hits? i was just thinking that it could be used with carbs to activate vtec.

 

controls vtech engagement by 100 rmp increasements, incresases fuel delivery by rpm, beep alert at redline, displays digital RPM reading.

The FIELDS controller interrupts the +12V signal(form the ECU) to the VTEC solenoid and sends a +12V signal to operate the solenoid. All the field does is sends +12V at the set RPM.

It DOES NOT have any control over the fuel maps of the ECU. All it does it changes the voltage to the map sensor to trick it that their is more/less air flowing. (Than the ecu adds/subtracts fuel)

For Instance, If your VTEC normally kicks in at 4400RPM (The ECU will send +12V to the VTEC solenoid and change over to the VTEC fuel/ignition Maps at 4400RPM)

If you set your VTEC to 6000RPM (with the FIELD), The ECU will send +12V to the FIELD unit (since the Field interrupts the +12V to the solenoid) and change to the VTEC fuel/ignition Maps at 4400RPM. (Since the FIELD interrupts the VTEC wire. It will send the +12V to the solenoid at 6000RPM, but it has no control over the VTEC fuel/ignition maps which will still change over at 4400RPM)

 

Do you know what pin the 12V goes to at the solenoid? I'm trying to make my own vtec switch.
