>I dunno, fooling around with fuel mixtureI was able to drop a full second on the 0-60 times so there is definitely powerto be had. I think with the 86 and later engines your options to eek out freepower are much more limited than the pre-86 since the pre-86 have basicallymechanical injection and the computer just adjusts timing by a constant amountfor a given engine rpm, so if I advance the base timing by 3 degrees, which Ishould have room to do since the car only asks for 87 and I run 93 I should beable to drop a few tenths on the 1/4 (I don?t know why I haven?tgotten around to this yet, I guess because I don?t want to buy a timinglight). But for the sake of checking my O2 voltage, does anybody know whatports you use to check the O2 sensor voltage on the CIS (no, it?s not thesame as the CIS-E, so Dan?s guide doesn?t help).
