I'm SW London
Re injectors, I did a resistance test on them. and they all read consistently, but slightly higher than the range given in RAVE. I didn't write it down at the time, but RAVE talks about 13.3k +/-1.3k - i think they all came in at 16k, I took consistency to be a good thing, but since I didn't really get the significance of the resistance test left it at that. At the time i hadn't heard of any of the techniques of blasting the injectors etc, so have never physically tested for leaks.
I haven't used an oscilloscope since school :o) wiil it tell me anything that nano doesn't?I can see the switching on nano - seems fairly regular now, voltages 0-5v, and generating s.t trims of +/- 10%, but usually +/-5%. For the first few trips on new sensors they were giving rise to some wild ST trims, but ok now.
Thanks for looking into the 39% Richard, my neighbours must hate me - I just finished fitting a new alternator to the wife's Audi. I wonder if the 39% is a default strategy, but then if it is, why...what does it think has failed to execute that. It's a very specific 38.75% - same on both banks @ start
