No, if you mean for your '94 - because it's OBD1 and the X3 only works on OBD2 and above. Your options are QuarterHorse and/or something like a Zeitronix wideband that will do A/F, Lambda, TPS%, RPM, MAF Volts, boost and another 0-5v source.
Hi
If I understand correctly if I bought this, then I could log my AFR,RPM,Boost and air temp, Probably $550 or so. Then I could take the log to my tuner and have him make changes my SCT chip??
