I have a 92 RMW w/L05. I have just completed the ultimate TBI mod and was wondering if I run the 92 9c1 injectors (65lbs) over the stock 60's do I need the ECM from the 9c1? Any help would be appreciated

 

That's about an 8% increase in fuel (assuming no pressure change).

I doubt you'd ever notice the difference. Might want to free up the air path, or cool it down - then you might notice a bit of change.

Run 'em for a bit, then check the color on your plugs. That'll tell you.

 

I swapped the 350, esc module, injectors, and ECM from a 92 9C1. All worked very well. I first tried swapping just the chips but had to swap ecms to make car(s) run properly. I would swap ecm if you have it unless you are going to custom program a chip in the one you already have.
