Re: i need to know
 

it has to do with the injectors you use, not the ecu software.

Re: i need to know
 

...and what car you currently have. Depending on your car, you may already have one installed.

92+ (Stock OBD1) will not have one, and therefore, you need to aquire one.

88-91 (Stock OBD1), with a multiport fuel injection system will not need one.

And like Fook said, this is in conjunction with what injectors you use... High impedence with OBD1 ECU, no need for a resistor box. Low impedence injectors with an OBD1 ECU, you'll need one.
