    In short...yes. Any 98-99 ECU can be. It just so happens that yours takes the most work to make it happen.

    That's a SOHC ecu, not sure about them. Let the ecu masters chime in

    The SOHC ECUs haven't been modified yet to clone a VR-4 ECU. It requires extensive work and I'm sure that will be a last option because there are plenty of other ECUs that can be modified. You'd be better off looking for a SL or VR-4 ECU.

    Is the 99 VR4 ecu the most inexpensive option when you add in the patch harnesses and additional work?

    I read somewhere an oem one is about $800. How much more or less do you have to throw at the coversion from a 99 vs a 98 ecu?

    98 and 99 are practically the same. Dealerships are out of them. A couple guys are converting montero and diamante ecus into perfect Vr4 clones for little expense compared to the real thing

    I got the ECU for pretty cheap so I'm hoping I can make it work. I've had a few offers for it but I'm considering keeping it.

    you need a patch harness with any flashable ecu if your car isn't a 98 or 99.
