Message	The 90-92 will work in the 94 however those years had AIV,s. You would have to get the numbers off the chip and ask JWT if the software has the idle software for the 90-92 or 93. If it has the older software it will idle a bit rich but will run fine otherwise. If you plan on custom software it should be fine the idle software is mute. Also the auto's have a differant VTC setting.
