4 channel Peak&Hold driver

Post by Sven »

Hello,

I'm using a KDFI V1.3 ECU in my car with duel fuel application. (Table switching).

For gasoline i use high Z injectors and for LPG i use low Z injectors.
For the Low Z injectors i would like to use your 4-channel peka and hold driver.

The injectors are 3ohm, can i use this driver?

thank you in advance,

Sven

If you mean this driver https://secu-3.org/en/product/4-ch-driv ... injectors/, then you can use it only for injectors with 4/1 peak to hold current ratio, so 4A peak and 1A hold. Check documentation on your injectors.

Hi,

I have ordered the unit.
Waiting for delivery, in the mean while i have an question about connection.

Must each output be connected to each injector? Mine fuel ECU has two channels and each channel is connected to two injectors.
