As i said i'd post... I'll post more specs and data sometime tommorow. I got other issues going on tonight non-car related. Pet is sick. :-( Did several tests tonight since my last post. First test was to run it on 19psi of boost just as i did yesterday. Knocked pretty good after 5200 r's just as its been doing.
Next test #2, I did the same boost level (19) but turned up the sliders in dsmlink from 4500rpms to 7500 to +8. Result: Knocked pretty good but not quite as much, probably 3.x degrees being pulled.
I checked the base timing then with the timing light. Dsmlink is nice because you can ground it just by clicking on a button on the computer. At about 750-800rpms, she was dancing right around 5 degrees BTDC. Correct me if i'm wrong. First time i did this. On a 2g, on the tbelt cover is the degree readout, the only number that is on there is a number 10. Then a couple of other lines and then what looks like a "T". I'm assuming that T means top dead. Well that's where the little white dot on the crank pulley was hovering around.
My next test #3, Put fuel sliders back to zero. Cranked boost back down to around 14.5psi. All be dammed! No knock in ANY gear. A couple times i had those little .4 degree phantoms but not all the time and hardly at all. Most of the time, it was knock free period. Ran this setup about 4 times with little to no knock.
What does this mean? The 93 octane i put in it the other day is shit? Not really 93 octane? With the refining troubles they're having, i really gotta wonder if we're pumping what its actually supposed to be. How watered down is gas nowdays? I'm gonna first switch to either Mobil or Citgo fuel. I expect the result to be the same though because i think all gas stations around here no matter the name get their gas from the same supplier. I have an alcohol injection unit that i took off the GST before i sold it. I need to get it on the GSX.
I'll post logs tommorow or something. I just got more important things than cars going on tonight. I just wanted to update you.
Good night.
