1.5 degrees retard x 12 psi = 18 retard. Doesn't that seem like alot of timing to be pulled for that amount of boost? Hmmm.

Guess it's better to be safe than sorry...especially if it's not your car!

Hey, do you understand 'open-loop' and 'closed-loop' conditions. I've been reading up on all kinds of archived posts on all kinds of cars about electronic O2 clamps, but still can't figure out if I'm supposed to raise or lower the output signal between the "clamp" (J&S Ultra v.2) back out to ECU.

From what I've read, I'm pretty sure I'm supposed to lower the ouput voltage, thus lowering the "stock set point" before the ECU goes into open-loop (where it pulls fuel and lean out...I think). But lowering the set point too much with the existing fuel pressure settings will create a "slimmer" closed-loop range, creating richer fuel conditions in that range (vacuum to 0psi).

Does that sound right?
