[Gmecm] Re: TBI injector schema vs. port injector schema

[William Lucke]

I know that the 730 can't drive more than one and that it would need 
external drivers to run multiple LoZ injectors. I was just wonndering if 
there was anything associated with the way the ECM calculates pulse 
width and fires the injectors that wouldn't work with TBI injectors.

Common sense tells me that as long as the PCM is programmed with the 
correct injector flow rate and the VE tables are dialed in that there 
shouldn't be a problem.
The one person who's told me otherwise seems content to be demagogic and 
not bother to explain himself so I have to assume that he's wrong and my 
common sense evaluation is correct.
