What length syringe needle are you using? I believe 1/2" is recommended and it has to go all the way in the penis side. Both sides ahould be alternated. Two to three days apart is also recommended. Vary the dose minimaly. Too much and he will pay the price with a prolonged erection and pain.
I don't believe you can get to far off of target with injecions. My experience says that emotions play a large part in firm erections. Same dosage can produce beautiful erections most of the time but with the right distraction I have seen it go soft in seconds and not return even with a fair degree of stimulation.
Convince your hubby to try the weak side again and continue the alternating repetition.
Let us know about your success.
