from what i heard, OBD1 only need one O2 sensor? so if i'm running a straight pipe, it won't throw a check engine light? any other advantages to go from OBD2 to OBD1?

 

that is correct. obd1 = 1 o2 sensor. u can run a straight pipe with out getting a CEL.

umm..
obd1 ecu is tunable
obd2 ecu is not.

obd1 has less sensors to worry about
obd2 has more. more of a headache.

 

will a chipped OBD1 ECU run a CEL?
can i use my stock OBD2 o2 sensor or will i need a OBD1 o2 sensor?

You just need a jumper harness with an OBD1 ecu. All OBD2 O2 sensors are the same.

 

so all obd1 and obd2 sensors are the same?<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by poison &raquo;</TD></TR><TR><TD CLASS="quote">

you said all OBD2 sensors are the same. so, i'm guessing all obd2 and obd1 sensors are all the same? 4 wire?

yes u can use the obd o2 sensor.

 

do the dizzy wires have to be switched around?

 

I think what poison meant was that all OBD1 & OBD2a/b 02 sensors are the same, which is totallly true.

When you use a jumper harness to convert OBD2a/b to OBD1, you don't need to worry about any wiring at all. It's all done within the jumper harness. Thats what makes a jumper harness soo coool -- plug n' play!

 

thanks for the info.
