    fuel injector balance test,

    Would like to see function to do fuel injector balance test. I think this is a function on the Tech 2. hook up a fuel pressure gauge, prime pump, then pulse injector for a set period of time. write down fuel pressure before and after for all 8 injectors, then compare the differences.

    Is this somthing that can be added? This would be a key on engine off test. The tech 2 limits you to only pulsing each injector one cycle unless you start the engine...to prevent flooding.

    I would like to second that motion! Far more useful in certain situations than the power balance test.

    What engine do you want to do that with...my VCM scanner (newer beta) has an injector balance test...it's done with the engine running, you take over control of the IAC and bring the RPM up, then it says it's ready, and you tell it to begin, it cuts injectors 1 at a time and monitors the RPM change.

    sounds like the feature we already have.... I'd like to control the injector being cut, and the length of time the injector is disabled...
