Anyone got any good 350Z UTEC links? I need to do some reading...

I went out first and tried no advance, +10, +15, and +20 and got worse results than Dave did. I believe my ks is toast because it is reacting the same way it did a couple of years ago on my 2k2 with the ks disconnected.
Then I came home and dug out a 470k ohm resistor for the ks and went out again. This is with 15 deg added but I also tried 10 and 20. At +20 added I had to shut it down the knock was very evident which is strange because I have ran +20 added which resulted in +41-43 total on the old A32 ECU with no knock.
So it appears as though the ks is pulling the timing but I will do a little more testing after I get another ks and maybe try desensitizing it to try and get a better picture of how it is reacting.
So now that I know I didn't mess up by swapping the ECU I will start tuning and hopefully make it to track this weekend. 35 deg was the optimum I found last year on the A32 ECU so I'm assuming it will be the same with the A33b.

Thanks Nmex, I'm pretty much sticking with WOT tuning because quite frankly I haven't the slightest as to how to tune at partial throttle. From what I've seen the ecu uses slightly higher timing at part throttle.
