As an experiment, I have been trying new things with camshaft timing. On my Corolla, I have a 3SGE 2.0L with variable valve timing on intake camshaft, I've moved the exhaust camshaft from the factory position to 16 degrees retarded. What this has done is increase overlap of the exhaust with the intake valves. This allows the exhaust to effect the intake filling cycle. The engine gained torque throughout the mid range as well as a bit above 6000rpm. I decided to try a version

NOTE: This is not a drop in modification and will require tuning of the Engine Control Unit (ECU). This mod is not exclusive to E85 usage. I have been tuning my 2007 Mazda Miata MX5 (NC) with an open source software for a while. I enjoy tuning as it gives me another level of depth that I can add to my vehicle. I can control and manipulate values to make the vehicle behave any way I want. I decided to experiment with E85 fuel. E85 is readily available near me and is relatively

The Mazda MX5 Miata is a competent vehicle for track duty. With a well designed suspension, and numerous well known upgrades it is very easy and relatively cheap to get started as a track-day vehicle. Many professionals and amateurs alike use the MX5 Miata to race. I purchased and have been using my 2007 MX5 for track days. Of all the components of the car, the front brakes have been the most interesting and yet untouched components on the car. At first, I had no issues with

To start with, I bought my Miata in order to attend track days. During track days, oil temperatures are more important than coolant temperatures. Just like coolant temperatures, oil can reach critical temperature. This can cause catastrophic engine failure if left to happen too long or too often. For this reason, I have chosen to install the water to oil oil cooler setup. In order to ensure engine reliability without introducing excessive complexity. The oil cooler on the NC
