The A4 is a relatively undemanding engine as far as ignition goes *except for being in a damp/wet environment*. IMHO the biggst gain from EI is that you won't have damp ignition starting issues. If you
need the EI just to make your engine work it has issues.

I never did check the voltage, I just installed the resistor supplied to me. I have been using it for a bit over a year now and did not notice that I had made any changes at all. The E/I will work will with lowered voltages, as long as you stay within suggested voltages. I absolutely did not notice anything  and I must say it did suprise me a bit  .
