The stock computer will not be ideal; you would at least need a tune, and another option would be a tunable aftermarket ECU. With aftermarket ECUs, the key questions aren't so much what mods you have (you can tune for a very wide range of mods); the real question is what features you want. For example, our MSPNP
for this car would have these features as a selling point for why it would be a good fit:
1. It plugs right into the stock wiring and mounts precisely in the stock location.
2. It has a 2 step rev limiter built in.
3. It adds the ability to use a knock sensor and listen to the sensor through headphones plugged into the ECU.
If you wanted to look at another ECU in our catalog, the MS3-Pro
is something you could compare it to. This one doesn't plug into the stock wiring, so you'd need to rewire it. It does, however, have some features the MSPNP doesn't, such as individual cylinder tuning, the ability to ramp up timing after launch to reduce wheelspin, and trans brake control.
So, when considering an aftermarket ECU, I'd say the biggest question is whether you want basic spark and fuel control at a reasonable price, or if you want to spend more to get more advanced features.
