Of all the phases of tuning, adding timing is where being on a dyno is most critical. You can street tune the Fuel and the VE and or MAF tables but adding timing should be done on a dyno. You have to look at it from this prospective. the purpose of adding timing is so you can maximize the power output of your vehicle, correct? With that said, you shouldn't just add timing untill you see K/R because its quite possible that the point at which the vehicle stops making power and the point at which the vehicle will knock are nowhere near eachother. Example a car can level off its power levels (i.e. not make anymore power) after adding 15 Deg. of timing, but still not be showing a hint of knocking yet. Yor first instinct would be to keep adding timing untill you reach that threashold of K/R. lets say you reach 20 Deg before it starts to Knock so then you back down to 19 Deg. theres no point of going to that 19 or even 18 Deg, because the car stopped making power back when you were at 15 Deg. of timing and now with the 19 Deg. your right at that threshold of the car pulling timing (i.e. taking power because it may or has a greater likely hood of knocking.)
Does that make sense?
Also, it would make it easier/better to look at your log files with your configuration file that way we can see exactly what your logging. Right off the bat though I can see that your VE table need some work so does your PE Fuel Mulitplyer vs. RPM table Whats your AFR at? Please dont tell me your tuning with out a W/B.
your VE Table needs some work
