My roommate's '00 turbo ITR is up and running now. Just finished the maiden voyage! We were playing with the J&S sensitivity adjustment and have a question. The J&S was set to "retard all" and the sensitivity to "midrange" par J&S instructions. The Tial has a 6 psi spring in it and the XS manual boost controller was turned all the way down. Ignition timing was set as 16 deg. When we floor it, the boost climbs to about 2-3 psi max. At approx 5000, some retard starts, maybe 2-3 lights, so 4-6 degrees. When VTEC transition happens, the thing goes crazy and fully retards, 10 lights (20 deg), and you physically feel the car slow. The A/F meter is still rich and hasn't budged. Is the sensitivty set too high or are we actually knocking that much? Reminder, this is only at 2-3 psi. Second question, in "retard all" mode, during partial throttle will all lights stay lit in a row if knocking is detected? We are going out to finish installing the fuel pressure gauge right now. Please help?

 

No your car isn't knocking that much. Set the sensitivity WAY down.
