I've seen the schematic, its quite different to the Mitsi output driver. It just switches the flywheel diode out of circuit on turn off, I tried that type of driver (and several others), the Mitsubishi guys knew what they were doing when they designed the output stage, the Zuk injector is very difficult to drive.
Have you actually got your MS2 working on an 8V?

I published an explanation of how the Suzuki injector driver works here:

Thanks for answering

Will start testing and scoping the injector

will try and keep posted

all i know on this TBI injector.

i found the dead time to be .7 milliseconds. Stock ecu sigs. watching for hours and trying every mode of ecu. cold , warm , hot. etc.

hope this helps you.

as you can see the circuit is not complex.

if you want full spec on injector send to a pro clean injector shop and they will give you all data on the injector. for a fee.
