I agree 100%..a healthy engine will resist flaming out even with a brutal tune....... Once a engine becomes unhealthy they become unstable and want to flameout ....Being that I sell modified engines my work is sometimes blamed for people's flameout issues and 99.9% time when the engines get torn down there is mechanical damages and neglect at the root of the issue....It is very unfortunate but some guys will go weekend after weekend with a flaming engine and never bother to do anything but chase the needles..... After weeks of failures and frustrations they finally contact me and by that time unfortunately the mechanical damages are beyond even my ability to repair...... If a engine starts flaming out for no reason its time to pull it off the track....... no ifs ands or buts...if you continue to fight the engine you are likely just working the dirt and damage deeper into he engine.....So ask yourself, is that last 10 minutes of the race worth scrapping your engine over ? As once dirt gets in the faster you shut it down, the greater the chances are of salvaging the engine.....
