Message: [QUOTE="Blowby, post: 369756, member: 711"] Typically your timing is controlled by SOI commanded from the computer. This time of injection in crank angle is precisely mapped for changing conditions. Injecting a fuel (methanol) into the intake track will alter the SOI. Once the valve begins to open and air/ methanol enters the intake the SOI will be now determined by heat/pressure to start the burn before the computer commands the injectors to open. This analogy shows how the timing is advancing but you have no control of where in crank angle degree's it's occurring. Using a small amount of methanol will help in cooling and not be enough to ignite prematurely. This will also effect the time your atomized diesel completes the burn which will alter your timing based on peak of expansion but it will always start at the commanded point as the injectors open.
