    Default Injector Balance test

    I have a GM 411 PCM that I'd like to use to do an injector balance test. I'd like to use the V2 to pulse individual injectors a fixed number of times. Something like: 50 pulses at 100Hz and 50% duty cycle. With the engine not running, I'd like to do this one injector at a time to compare fuel delivery results.

    I've seen this done with the GM Tech2. I'm not seeing any mention of this in the EFI manual. I found a forum thread from 2008 that mentions a balance test, but nothing else.

    Can the V2 do a balance test? Where can I find info about it?

    Thanks

    i guess the v2 cannot do this (like e.g. a motec).

    you can get an unexpensive pulse generator ($5 ?) and a fet driver to pulse injectors.
