  3. 2.0L FC2 and FC4 Development Thread

    Well it's what you would expect. A thread revolving around the development and custom work done to the FC2 and FC4 platforms as well as their aftermarket support.

  4. KTuner 90 Octane

    HI, I have a K20C2 so no turbo to worry about with tuning. I'm well aware if I get a Ktuner and put 87 in it it will pull timing and possibly damage the engine over time. However, in my city, the highest octane I can get is 90. Is it possible to mess with the tune to get it to run OK on 90...

  7. K20c2 e85

    I understand that the k20c2 cannot be tuned for e85 with the stock ecu using ktuner. But now that there’s a maxx ecu harness from @Awdfk8machinist it is possible to tune for it with the maxx ecu sport. With tuning for e85 on the C2 now being possible, what other parts would I need to run e85...
